Terms and conditions

The effective date is the date this version is first published on the Buildner BIM Tools website. These Terms apply prospectively, subject to section 24.

1.1. The website and BIM utilities on which these Terms are expressly presented, referred to as Buildner BIM Tools or the Site, are operated by BUILDNER, SLU, a company established under the laws of the Principality of Andorra, registration number 715322-T, with its registered address at Carretera Mas de Ribafeta 6, 3-1, Arinsal, La Massana, AD400, Andorra. In these Terms, we, us, and our mean BUILDNER, SLU.

1.2. The Site is affiliated with buildner.com and forms a distinct BIM tools offering. Its separate operation does not make it a separate legal entity from the operator identified above. A Tool may be presented on its own page or subdomain; these Terms apply where that Tool is expressly identified as part of this Service and these Terms are made available to you.

1.3. These Terms apply to the Site and its building information modelling (BIM) utilities, schedule and parameter comparisons, completeness and consistency checks, coordination aids, IFC information checks, drawing-register reviews, issue documentation, explanatory materials, examples, previews and exports, together the Service. Each utility is a Tool. Sections relating to accounts, profiles, uploads, hosted storage, sharing, artificial intelligence (AI), or paid access apply only when we offer the relevant feature and you use it.

1.4. Other Buildner websites, including the general architecture tools at tools.bnr.ac, competitions, courses, subscriptions, publications, reviews and other services, have their own applicable terms. These Terms do not govern those separate services or change your rights or obligations under their contracts. Shared branding, ownership, links, sign-in or technical infrastructure do not combine the services into a single offering.

1.5. The privacy notice made available for this Site separately explains the handling of personal data, including relevant website and hosting activity. Tool-specific file-processing notices describe the local handling of project content. These Terms describe permitted use and functional processing; they are not a privacy policy, a data-processing agreement, or consent to marketing, tracking, or unrelated use of your information.

1.6. If we introduce additional terms for a particular Tool, we will identify them and make them available before they apply. An expressly agreed, more specific provision takes priority only for the subject it addresses. Mandatory legal rights always take priority.

1.7. The current BIM utilities process supported project content locally in the browser, as described in section 8 and the relevant Tool. The conditional provisions for accounts, profiles, online storage, sharing, paid access and remotely processed AI do not state that those features are currently available. Describing a possible feature does not promise its launch, a launch date, or access in any location or account. The tool-specific schedule at the end of these Terms forms part of them; it describes the limited purpose of each Tool and must be read with the general provisions.

2.1. By selecting an acceptance control, or using the Service after being given clear notice of these Terms and a reasonable opportunity to read them, you agree to these Terms to the extent that a binding agreement can be formed in that way under applicable law. If you do not agree, do not use the Service.

2.2. The Service is intended for adult architecture and design students, educators, architects, engineers, BIM managers, coordinators, technicians, designers and other people who need practical assistance with BIM information and coordination workflows. You do not need a professional qualification to use the Tools, but using them does not qualify you to undertake regulated professional work.

2.3. You must be at least 18 years old and legally capable of entering into this agreement. The Service is not offered for independent use by children.

2.4. If you use the Service for a business, practice, institution, or other organisation, you confirm that you have authority to accept these Terms on its behalf. In that case, references to you include that organisation where appropriate. If you lack that authority, do not accept these Terms on its behalf.

2.5. A Consumer is a person entitled to consumer protection under applicable law. A Business User is a user acting for purposes relating to their trade, business, craft, profession, or institutional activities and who is not entitled to consumer treatment for that use. Your legal status depends on the circumstances and applicable law, not simply the label used in these Terms.

3.1. The Service provides self-service digital utilities that compare, check, calculate, organise, document or display information you supply. Depending on the Tool, this may include exported schedules, drawing registers, room briefs, parameter definitions, identifiers, GUIDs, categories, types, dimensions, areas, units, coordinates, warning reports, IFC metadata, issue descriptions, assignees, due dates, screenshots, requirements, tolerances, mapping choices and export settings. A supported account feature may also hold the information and preferences necessary for its operation.

3.2. The BIM offering includes What changed? / Schedule comparison, Room check, Door check, Missing data, Parameter Match, Alignment check, IFC check, Warning sorter, Ready to issue? / Drawing package check, and Issue pack, where available. The tool-specific schedule below explains their respective scope. Supported formats and limits are shown in each Tool; an ability to read one export format does not imply support for every file from the same authoring application.

3.3. The Service may produce comparison tables, counts, completeness percentages, warnings, classifications, suggested priorities, coordinate diagnostics, diagrams, issue packs, printable reports and downloadable files. These results are Outputs. A Tool checks only the information, rules and relationships that it expressly supports. It does not automatically access your authoring model, linked models, common data environment, document-management system or live project database.

3.4. The Service works with the information and assumptions available to the relevant Tool. It does not independently inspect a site, measure an actual building, establish the authenticity of a file, verify that an export represents the latest authorised model, or check omitted information. A file import, coordinate fit or status label is not a complete or professionally verified review of the underlying project.

3.5. Examples, default values, suggested settings, and sample files illustrate how a Tool works. They are not requirements, recommended specifications, or confirmation that a setting is suitable for your circumstances.

4.1. The Tools are currently available without a charge from us. You remain responsible for your own internet, device, printing, software, and other third-party costs.

4.2. Free availability is not a promise that the Service, every Tool, or every feature will remain free indefinitely. We reserve the right to introduce charges for future access or use, including one-off fees, subscriptions, AI requests or credits, account or storage allowances, paid exports, premium features, or business licensing. We may also change which features are included in a free offering.

4.3. Before you incur a charge, we will clearly disclose the relevant price, currency, applicable taxes, billing basis, and material purchase conditions. For a subscription, this includes its duration, renewal arrangements, and how to cancel. Any applicable withdrawal, refund, and digital-service rights will also be explained before purchase.

4.4. We will not retrospectively charge for use that was free when it occurred. Using a free Tool does not authorise a payment, create a paid subscription, or give us permission to charge a payment method held in connection with another Buildner service.

4.5. Moving you to a paid offering requires your express agreement to that purchase and its applicable terms. If you do not agree, you may stop using the affected offering and continue using any free functions that remain available.

4.6. Introducing charges does not itself withdraw the permitted rights in Outputs you lawfully created and downloaded while the Service was free. Existing paid commitments, if any, remain subject to the terms agreed for them and applicable law.

5.1. Subject to these Terms, we grant you a limited, non-exclusive, non-transferable permission to access and use the Service through its intended interfaces for your own lawful personal, educational, and professional work. This permission lasts while the relevant Service is available to you and may be restricted or terminated in accordance with these Terms.

5.2. You may use the Tools to assist with work for your employer or clients and may include permitted Outputs in your own project materials. Charging a client for your professional work is permitted; selling access to our Tools or passing off the Service as your own is not.

5.3. This permission does not include a right to copy, host, distribute, sublicense, embed, white-label, or resell the Service or to provide it as a competing or substitute service. A separate written agreement is required for those activities.

5.4. You may keep a copy of these Terms for your records. Normal browser caching, accessibility functions, and other acts necessarily incidental to permitted use are allowed. Rights that applicable law or a separate open-source licence grants you are unaffected.

6.1. This section applies only if an account or profile feature is offered. The browser-local BIM checks do not, by themselves, create a hosted project account or save project content with us. Some hosting environments may separately require sign-in to access a page. Where a feature requires an account, sign-in or profile, you may use it only through an account you are authorised to access. Creating an account does not guarantee access to every Tool, a particular storage allowance or a future feature.

6.2. Provide accurate information where it is required for account operation, eligibility, or communication, and keep that information reasonably up to date. Do not impersonate another person or organisation or misrepresent your identity, age, authority, qualifications, or professional status.

6.3. Protect your password, sign-in links, authentication codes, and connected sign-in methods. Use available security controls appropriately, keep recovery details current, and sign out on shared devices. We may request reasonable verification before granting access, recovering an account, changing its ownership details, or acting on a closure request.

6.4. Tell us promptly at contact@buildner.com if you suspect unauthorised account access or disclosure of your sign-in details, and take reasonable steps to secure your account. You are responsible for activity you authorise and, to the extent applicable law provides, activity caused by your failure to take reasonable care. You are not automatically responsible for every action taken through a compromised account or for a security failure for which we are legally responsible.

6.5. Unless a feature expressly supports shared or organisational access, an account is for its registered user. Do not sell, transfer, rent, or share personal sign-in credentials or give another person access in order to bypass limits or restrictions. Use any supported invitation or permissions controls when authorising another user.

6.6. A profile may hold information you provide about yourself, your work, or your preferences. A profile or account label is not verification of professional registration, qualifications, identity, or the quality of your work unless a specific verification is expressly described. You must not suggest otherwise.

6.7. If a feature offers a public profile, shared workspace, or public project page, the relevant controls will explain what is visible and to whom. Check those settings before adding materials or enabling access. Creating an account or uploading a file does not, by itself, grant permission to use your private project materials in a public gallery, testimonial, or advertising campaign.

6.8. If you join a workspace expressly managed by an employer, institution, or another organisation, its authorised administrator may have the access and management powers stated for that workspace. Confirm that you are entitled to place the materials there and that the stated permissions are appropriate. An organisation does not gain control of a personal account merely because you use its email domain, unless an applicable managed-account arrangement has been clearly disclosed and validly agreed.

6.9. An account or sign-in method associated with another Buildner service may be used here only where the Site offers that option. Shared sign-in does not make these Terms the terms for that other service, combine separate purchases, or authorise payment using an arrangement made elsewhere.

6.10. Do not create duplicate or automated accounts to evade restrictions, obtain allowances dishonestly, or restore access after a justified suspension without permission. We may take proportionate steps to verify eligibility, investigate misuse, and protect account access in accordance with these Terms.

6.11. Account messages about sign-in, security, stored materials, important Service changes, or account closure may be sent to your registered contact address or through the Service where legally appropriate. Keep that address accessible. These operational communications do not constitute permission to send unrelated marketing.

7.1. Inputs means the files, exported schedules, IFC content, parameter definitions, drawing registers, warning reports, coordinates, brief requirements, text, screenshots, images, prompts, instructions, settings and other materials that you enter, select, import, upload, save or otherwise make available through a feature. Importing a file into a browser-local Tool is not the same as uploading it to us. Your account and profile details, where applicable, are also covered by your duties to provide accurate and authorised information. Personal-data rules are set out in the applicable privacy notice and law.

7.2. You retain the ownership and other rights you already hold in your Inputs. Using the Service does not transfer ownership of your designs, drawings, or project materials to us.

7.3. You must have the necessary rights, permissions, and authority to use your Inputs with the Service and to create, use, and share resulting Outputs. This includes any relevant permission from a client, employer, collaborator, copyright owner, or other rights holder.

7.4. You must not provide materials in breach of intellectual property rights, a confidentiality duty, a contractual restriction, a court order, or applicable law. Before processing or storing confidential project materials, confirm that the feature's stated operating method, including any remote storage or AI processing, is permitted by your obligations to the owner of those materials. The Service is not a facility for classified information or materials requiring a specially agreed regulated hosting arrangement unless we have expressly agreed that arrangement with you.

7.5. You are responsible for selecting the intended project, discipline, phase, revision, export scope and source files; checking that Inputs are complete and accurate; choosing appropriate identifiers and column mappings; using consistent units and coordinate systems; and reviewing rules and settings before relying on or exporting a result. Include the information required for the intended check. An omitted category, filtered-out row or parameter absent from an export cannot be assumed to have been assessed.

7.6. Use any dedicated sign-in, payment, or verification interface only for its stated purpose. Do not place passwords, authentication tokens, payment-card information, identification documents, or unrelated sensitive information in project files, profile descriptions, AI prompts, or support messages. Do not assume a Tool removes personal information, hidden content, or identifying metadata from an Output unless that function is expressly stated.

7.7. You are responsible for the decisions you make using the Service and for the project materials you issue to others. These responsibilities do not remove any obligation or liability that the law places on us.

8.1. By using a feature, you authorise the technical operations reasonably needed to provide that feature. For the current browser-local BIM utilities, these are local operations such as reading selected files, parsing pasted text or IFC data, comparing records, applying rules, calculating diagnostics, rendering previews, handling attached snapshots and generating downloadable reports or editable files. These operations do not grant us remote access to files that remain on your device.

8.2. Current local processing. The current BIM utilities process imported project files, pasted project content and entered check data in browser memory. Their application code does not upload that project content to Buildner, provide Buildner with access to it, or save it in a Buildner project database. Downloaded reports and editable packs are created on your device. The Tools do not deliberately persist this project content in cookies, localStorage, sessionStorage or IndexedDB. This statement concerns project-content processing by these Tools, not ordinary page requests, hosting or authentication logs, browser-managed restoration, device backups, extensions or separately authorised assistants. Keep and download any work you need; local processing is not a promise of permanent retention or recoverability.

8.3. If remote features are introduced. An expressly offered upload, account-storage, sharing or remotely processed AI feature may transmit the relevant materials to systems operated by us or our technical providers. Before such a feature is used, its description and controls will explain what is sent and why. A file processed locally is not necessarily kept local if you subsequently choose to save it online, send it to an AI feature, share it through another service, or attach it to a support message. These Terms alone do not enable or authorise a hidden upload of existing local project content.

8.4. To the extent a legal licence is needed, you grant us a non-exclusive, worldwide, royalty-free permission to reproduce, technically adapt, analyse and display your Inputs through the local functions you invoke. Only where you actually provide materials to us through an expressly offered remote feature, sharing function, or support channel does that permission additionally extend to receiving, hosting, storing, organising and transmitting them, and only as reasonably necessary to supply that function, provide requested support, protect its security and integrity, and meet applicable legal obligations. The worldwide scope allows distributed infrastructure where remote processing is selected; it does not override personal-data transfer restrictions or create access to a file we have not received.

8.5. We may extend that limited permission to hosting, storage, AI, and other technical providers only to the extent necessary for their role in supplying those functions. The licence does not give those providers a general right to sell, publish, or independently exploit your materials. Access by our staff or providers is limited to the permitted service, support, security, and legal purposes; these Terms do not authorise unrelated examination or use of your work.

8.6. This permission does not authorise us to sell your Inputs, publish your unpublished work except through a sharing function you choose to use, use your work in advertising, enter it into a competition, or use it to train a general-purpose artificial intelligence model. Operating an AI feature on your instructions is different from training a model on your materials. Any additional use requires a separate lawful basis and, where a licence or consent is required, a separate agreement or consent.

8.7. The permission lasts for the period needed to supply the features you use, including the storage of materials you choose to keep in your account, and for any limited period needed to complete deletion, maintain lawful restricted backups, handle a dispute, or meet a legal obligation. It does not create a general right to exploit your project materials after those purposes end. Personal-data retention details belong in the separate Privacy Policy.

8.8. If a new function materially changes the processing of your materials, such as sending a previously local file to a remote service, we will explain that change before you use the function and obtain any agreement or consent required by law. Creating an account alone does not authorise publication of your project files or submission of every stored file to every AI feature.

9.1. As between you and us, you retain the rights in your Inputs that are reflected in an Output. We do not claim ownership of your original project work merely because a Tool helped calculate, display, compare, or export it.

9.2. To the extent an Output contains material owned by us that is intentionally included by an authorised export function, we grant you a non-exclusive, worldwide, royalty-free, continuing licence to use, reproduce, and adapt that material as part of the Output for your lawful projects and to share those project materials with clients, collaborators, educators, and other intended recipients. Any clearly disclosed asset-specific restrictions remain applicable.

9.3. That permission does not allow you to extract and commercialise our software, branding, interface, template library, or other Service materials as a standalone product or service. It does not grant rights in third-party materials that you are not otherwise entitled to use.

9.4. You may edit an Output, but you must not falsely represent an edited or unedited Output as certified, independently checked, professionally approved, or endorsed by us. Use of the Service does not make us the author, designer, architect, engineer, or approving authority for your project.

9.5. Outputs may be similar to those produced for other users. We do not promise exclusivity, originality, copyright protection, registrability, or freedom from third-party rights. Numerical results, formulae, and other factual material may not be capable of exclusive ownership.

9.6. Before distributing an Output, review its accuracy, completeness, formatting, permissions, and suitability for the intended recipient and use. Download and retain your own copy where needed.

9.7. To the extent we acquire any transferable intellectual property rights specifically in AI-generated content produced for you through your authorised use of the Service, we assign those rights to you. This does not transfer our software, models, templates, branding, pre-existing materials, or third-party rights. It does not promise that an AI Output attracts intellectual property protection or that you can exclude other users from independently receiving similar content.

9.8. If an Output reproduces third-party content, you remain responsible for obtaining any permission needed for your intended use. An AI response cannot grant you someone else's rights or confirm a licence merely by saying that content is free to use.

10.1. The Service provides general information checks, calculations, comparisons and workflow assistance. It does not provide project-specific architectural, engineering, surveying, planning, building-control, fire-safety, accessibility, legal, financial, valuation or other regulated professional advice. It is not an appointed BIM coordinator, lead designer, information manager, checker, certifier or contract administrator.

10.2. Using the Service does not create a professional appointment, consultancy engagement, fiduciary relationship, or duty to supervise your project. We do not undertake to inspect, approve, certify, sign off, or monitor your work through the Service.

10.3. Do not use an Output as the sole basis for construction, fabrication, installation, procurement, a regulatory submission, a contractual commitment, or a decision affecting health, life, safety, or material property interests. Obtain independent checks and appropriately qualified professional advice before those uses.

10.4. You remain responsible for checking applicable laws, building regulations, planning requirements, accessibility standards, fire and structural requirements, professional obligations, project specifications, and contractual requirements. A Tool result does not establish compliance with any of them.

10.5. A label such as “clear”, “pass”, “within tolerance”, “complete”, “matched”, “reviewed”, “resolved”, “no issues” or “ready” relates only to the stated check, information, settings or user-entered status. It is not a statement that a model, building, drawing package, door, room, parameter, coordinate system or issue is safe, compliant, correct, coordinated, approved, complete or suitable for construction. A percentage measures only its stated denominator; 100% completeness is not 100% correctness.

10.6. Using the Tools does not submit, formally issue, approve, register or deliver your work to a client, consultant, contractor, public authority, competition, course, publication or other service. It does not satisfy a contractual hold point, design review, statutory inspection, certification, information-delivery milestone or common data environment approval process. You must independently complete the applicable review, communication and acceptance requirements.

11.1. Results can be affected by incomplete or incorrect Inputs, export settings, unsupported syntax, matching rules, formula assumptions, rounding, numerical precision, unit conversion, software errors, browser behaviour and the limits of the relevant method. False positives and false negatives are possible. Check important results independently, including against the original model or a separate calculation where appropriate.

11.2. Information scope. A schedule is a selected representation of project information. Filters, phases, design options, linked files, view settings, deleted or hidden elements, type versus instance properties and authoring-software permissions can change what is exported. A Tool cannot establish that an export includes everything required for your intended review. A result applies only to the supplied scope at the time of the check.

11.3. Identifiers and matching. Choose identifiers that have the intended meaning and are sufficiently stable and unique for the check. An Element ID may be meaningful only within its source model; a room number, mark, name or GUID may be duplicated, reused or changed. A match in supplied identifiers is not independent proof that two records refer to the same real-world object. Different Tools apply different case, whitespace and leading-zero rules; follow the relevant instructions.

11.4. Units and coordinates. Check length and area units, number formats, origins, axes, orientation, signs, reference points, transformations and tolerances. Decimal symbols, thousands separators, precision loss and spreadsheet conversion can change meaning. A numeric comparison does not imply unit conversion unless the Tool expressly performs it. A fitted transformation of control points is not proof of whole-model coordination or verified survey control.

11.5. Presence versus correctness. A non-empty field may still be incorrect, obsolete, misleading or inappropriate. A text match does not establish equivalence between technical classifications. A detected inconsistency does not establish which source is authoritative. You must decide the correct value and resolve the underlying source information.

11.6. Requirements and standards. User-selected required fields, placeholder values, expectations, type groupings, tolerances, priorities and issue statuses are your review criteria. Examples and defaults are illustrative. The Service does not independently establish your employer’s information requirements, exchange information requirements, BIM execution plan, level of information need, measurement rules, classification system, Information Delivery Specification, national annex, ISO 19650 obligations or contractual deliverables. A result is not certification against any such document or standard unless an expressly agreed service specifically provides that certification.

11.7. Versions and stale results. Re-run a check after changing source data, mappings, assumptions, criteria or relevant model information. A downloaded report is a snapshot and does not update when its source changes. Some Tools disable export after settings change; you must still verify that the result reflects the intended current state. Record enough source and setting information to reproduce an important check.

11.8. Filters and exports. A filtered or paginated screen may show fewer records than the full result. Export scope varies by Tool and format. For example, an Issue pack printable report follows the selected review filter while its CSV and editable pack include all issues. Read the export description and inspect the actual downloaded file before sharing it. A zero-row view caused by a filter is not evidence of an issue-free source.

11.9. Spreadsheet and document handling. Exported text may be quoted, escaped or prefixed to reduce the risk of spreadsheet formula interpretation. That protection is not a guarantee against every application behaviour, macro, link or later edit. Opening or re-saving a report in another application may alter leading zeros, dates, GUID formatting, delimiters, encoding, number precision or escaped values. Check the saved result and do not enable active content from an untrusted source.

11.10. Project records. A report is a working record, not a tamper-evident audit trail, digital signature, immutable revision history, legally verified timestamp or proof of receipt. A status entered by a user records that entry; it does not establish that the underlying work was inspected, fixed or accepted. Do not present a Tool export as an independent certificate or conceal its scope, settings or limitations when another person is expected to rely on it.

11.11. Model changes. The current Tools do not write corrections back into native authoring models or automatically resolve the issues they report. You are responsible for reviewing proposed actions, making authorised changes in the source system, coordinating affected parties, and checking the revised export. A downloaded comparison or issue pack is not proof that an authoring model was modified.

11.12. Safe reliance. Maintain appropriate review, professional sign-off, backups and project controls. Do not bypass those controls because the Service reports a favourable status. The tool-specific schedule below forms part of the explanation of each Tool’s limited capabilities. These responsibilities do not excuse our own breach or remove any non-excludable legal right.

12.1. This section applies when we expressly offer an AI feature. The current deterministic BIM checks, matching rules and calculations are not represented as AI professional review. A future AI feature may analyse supplied materials, extract information, respond to prompts or generate and modify text, images, diagrams or suggestions, including through a third-party provider. We will identify the feature and AI interaction or generated content where required by law. An interaction with AI is not an interaction with a human professional.

12.2. To provide the AI function you choose, relevant prompts, instructions, files, selected saved materials, and contextual information may be transmitted to and processed by the AI systems supporting that function. The functional permissions in section 8 apply. Do not submit client or other restricted materials unless you are authorised to use them in that manner. Using an AI feature does not authorise unrelated model training or blanket processing of every file in your account.

12.3. AI Outputs can be incorrect, incomplete, misleading, outdated, biased, or internally inconsistent even when they appear confident, precise, or persuasive. They may invent facts, citations, measurements, quantities, regulatory references, materials, or features that are not present in your Inputs. AI may also overlook information, misread a drawing, misunderstand scale or symbols, or fail to follow an instruction.

12.4. Review every AI Output before relying on it, saving it as an approved result, sharing it, or taking action. Verify relevant facts and references against authoritative sources and independently check calculations, dimensions, specifications, and regulatory statements. Use appropriately qualified human judgment for project decisions. A request to “check”, “verify”, or “make compliant” does not turn an AI response into a professional verification or certification.

12.5. AI results are not a substitute for the independent checks required by sections 10 and 11. Do not rely on an AI feature as the sole basis for construction, fabrication, installation, safety decisions, regulatory approval, or a binding professional or commercial commitment. The Service is not designed to make consequential eligibility or suitability decisions about individuals.

12.6. AI Outputs can vary between requests, even when the Inputs appear identical. Changes to a model, provider, settings, or available context may change results. We do not guarantee a particular model will remain available, an exact Output can be reproduced, or a generated result will be unique, protectable, non-infringing, or suitable for your particular project. Your rights in Outputs are addressed in section 9.

12.7. A successful AI request means only that the system has returned a response; it does not confirm that the requested task was completed correctly. A response saying that a file was saved, a calculation checked, or another action completed is not independent proof of that action. Check the relevant file, result, or Service confirmation. Review proposed changes before applying them to original materials or important work.

12.8. You must not use AI-generated content to fabricate qualifications, approvals, inspections, project evidence, or another person's statements. Do not represent a generated image as proof that a depicted building, condition, material, or completed project actually exists when it does not. Make any disclosure of AI use required by applicable law or by the rules of the client, institution, competition, or platform to which you submit the work.

12.9. Do not remove or defeat a disclosure, provenance marker, or technical marking where retaining it is required by law or a clearly disclosed lawful condition of the relevant feature. We remain responsible for transparency or marking obligations that the law places on us; this section does not transfer those obligations to you.

12.10. AI features may apply limits on requests, file sizes, processing time, context length, or available functions. Requests may fail, be delayed, be refused, or produce only a partial result. Do not evade reasonable safeguards or usage limits. Any future charge, credit arrangement, or paid usage allowance must be disclosed and agreed as described in section 4; an unsuccessful request does not remove any remedy required by law or an agreed purchase term.

12.11. Third-party AI systems may be updated or replaced as part of maintaining the Service, subject to our obligations concerning functionality, notice, and the permitted use of your materials. A provider's involvement does not enlarge the licence you grant us or excuse obligations we owe you. Material changes to how your files are used will be handled under section 8 and applicable law.

13.1. You are responsible for providing a compatible device, browser, internet connection where required, and sufficient processing capacity and storage. Support for particular devices, browser versions, file formats, file sizes, and export types may vary.

13.2. A file extension or successful import does not guarantee that a file is valid, complete, safe, correctly interpreted, or suitable for the requested operation. Keep original files and work from copies where appropriate.

13.3. Where account storage is available, you may upload and save supported materials for later use within the feature's stated limits. Storage capacity, supported formats, maximum file sizes, version history, and retention arrangements depend on the function or offering described on the Site. Free access does not promise unlimited or permanent storage.

13.4. A file selected on your device, a displayed preview, or an AI response appearing on screen is not proof of a successful upload or save. Check the relevant completion indication and that a saved item can be retrieved. Closing a tab, refreshing a page, clearing browser data, changing devices, a software update, a browser crash, or a technical failure may cause unsaved work to be lost.

13.5. Hosted storage is a convenience for using the Service and is not a substitute for your own independent backups. We do not promise a particular backup frequency, recovery point, version history, or restoration service unless expressly offered or required by law. We do not undertake to recover local materials we never received. These limits do not exclude responsibility that applicable law places on us for a failure of a storage function we have agreed to provide.

13.6. For the current local Tools, refreshing or closing the page, replacing the current dataset, loading an example, resetting the Tool or a browser failure may discard the working state. A “saved” editable file means a file downloaded to your device where that is how the Tool describes saving; it does not mean we hold a recoverable copy. Check that the download succeeded and retain it independently. Browser or device-managed backup and restoration behaviour is outside the Tool’s own persistence controls.

13.7. You may manage or delete stored materials through the available controls or contact us for assistance. Deleting a project, closing an account, or changing access permissions may make related files, working copies, links, and saved Outputs unavailable. Do not delete your only copy of materials you need. The rights to retrieve content that applicable law gives you remain unaffected.

13.8. We may reject, quarantine, or remove materials that are unlawful, infringe rights, contain harmful code, exceed disclosed limits, or otherwise breach these Terms. We may also remove materials in response to your deletion request, account closure, a lawful order, or discontinuation of a storage feature in accordance with these Terms.

13.9. Before a planned storage reduction, closure of a long-unused free account, or discontinuation that would remove lawfully stored materials, we will give reasonable advance notice and an opportunity to download available materials or keep an eligible account active. Urgent legal or security action may require a shorter period or prevent access to particular materials. Any mandatory notice period, right to retrieve content, or other remedy takes priority.

13.10. Account closure or deletion does not necessarily erase every lawful backup or record immediately. Any remaining copy is subject to restricted purposes and the limited permission in the processing section. These Terms do not establish an indefinite right to retain or reuse your work.

13.11. If a feature allows sharing, collaboration, or public display, check the stated audience and permissions before enabling it. Your choice authorises us to make the selected materials available to that audience for that purpose. A recipient may keep a copy they have lawfully obtained; disabling a link does not itself recall copies already downloaded. Public or shared access does not transfer ownership or grant rights beyond the permissions you validly provide and applicable law.

14.1. You must not, and must not assist another person to:

• use the Service unlawfully, fraudulently, deceptively, or in breach of another person's rights;
• copy, republish, distribute, sell, rent, sublicense, white-label, or commercially offer access to the Service without our written permission;
• clone or reproduce protected parts of the Site, including its software, visual assets, interface, documentation, or organised content, to build a substitute or competing offering;
• frame, embed, mirror, proxy, or integrate the Service into another website or product without authorisation;
• scrape, crawl, harvest, or systematically extract protected materials or Service results, manually or automatically, to create a database, dataset, content feed, model-training corpus, or competing service without permission;
• access the Service through unauthorised scripts, bots, headless browsers, bulk requests, or undocumented interfaces;
• bypass or interfere with access controls, payment requirements, limits, blocks, security measures, or restrictions, including by rotating accounts, identities, devices, or network addresses;
• exploit a bug, vulnerability, exposed credential, or configuration error to obtain unauthorised access, free paid functionality, another person's materials, or an unfair technical advantage;
• introduce malware or harmful code, conduct denial-of-service activity, or send Inputs designed to disrupt the Service or consume unreasonable resources;
• probe, scan, or test security without authorisation, except where a published security programme or applicable law expressly permits the activity;
• access, change, delete, or interfere with another user's information, work, session, or access;
• create impersonating or deceptive profiles, disclose another person's private information unlawfully, or use account, upload, or sharing functions for harassment, unlawful threats, spam, or illegal content;
• bypass AI safeguards, manipulate a Tool into exposing another user's materials or confidential system information, or use prompts or uploaded files to gain access beyond your permission;
• use AI features to generate unlawful instructions, fraudulent evidence, forged professional approvals, or misleading impersonations, or to make consequential decisions about a person's eligibility, employment, credit, or access to essential services;
• decompile, disassemble, or reverse-engineer the Service except to the extent a non-excludable legal right or an applicable software licence permits it;
• remove proprietary or attribution notices from Service materials, or falsely claim ownership, partnership, certification, or endorsement;
• use the Service to facilitate plagiarism, rights infringement, forged approvals, falsified project records, or other dishonest conduct; or
• use the Service as a safety-critical control system or as the sole verification method for decisions affecting life or physical safety.

14.2. Ordinary use of permitted Outputs in your own paid professional work is allowed under sections 5 and 9. That permission does not extend to exploiting the Tools themselves as a product or service.

14.3. Accessibility software and browser assistance that a Tool expressly supports are permitted when used for your own authorised session and within the same limits as ordinary interactive use. You must review any settings, actions, or Outputs produced through that assistance. Supporting a browser assistant does not grant an unrestricted API, scraping, or bulk-processing licence.

14.4. Conventional search-engine indexing is permitted only to the extent allowed by our published crawler instructions and applicable law. It does not authorise republication of the Site or provision of its interactive functions through another service.

14.5. These restrictions do not prevent lawful criticism, an honest review, use of unprotected ideas or mathematical principles, or an act that applicable law expressly permits notwithstanding a contractual restriction.

15.1. Except for your Inputs, rights preserved in Outputs, and materials owned by others, we or our licensors retain all rights in the Site and Service, including their software, original content, graphics, designs, documentation, branding, and protected compilations.

15.2. Access without a charge does not make the Service public domain or open-source software. No ownership or licence is granted by implication beyond the permissions stated in these Terms or a separately applicable licence.

15.3. Buildner names, logos, and other brand assets may not be used in a way that suggests ownership, sponsorship, partnership, approval, or endorsement without permission. Accurate references to the Site and other uses permitted by law remain allowed.

15.4. You may share an ordinary link to a public Site page if the link is accurate, lawful, and does not misleadingly present our Service as your own. Linking does not grant a right to embed or reproduce a Tool.

15.5. If a component is supplied under an open-source or third-party licence, that licence governs the rights it grants in that component. These Terms do not reduce rights that such a licence validly grants you.

16.1. The Site may refer or link to third-party information, authoring applications, software, schemas, standards, BIM platforms or other resources. A reference is provided for compatibility, context or convenience and does not, by itself, constitute endorsement, affiliation, certification or a guarantee. Autodesk, Revit, buildingSMART, IFC and other third-party names or marks belong to their respective owners; referring to them does not make those owners operators, sponsors or approvers of this Service.

16.2. External services are governed by their own terms. You are responsible for deciding whether to use them and for any commitments you make directly with their providers.

16.3. We do not control independent third-party websites, browser extensions, or services you choose to use. Their content, availability, and conduct are their responsibility. This clause does not excuse our own contractual obligations or responsibility for providers we engage to perform those obligations.

16.4. Hosting providers help us supply the website. If we offer remote storage or AI functions, the relevant technical providers may help supply those functions. Their technical limitations may affect availability, supported inputs or results. We remain your contracting party for the Service we provide. If a feature requires you to enter into a separate agreement directly with another provider, that requirement and the relevant terms will be identified before you choose that feature.

17.1. You may contact us with questions, suggestions, error reports, or security concerns. Do not include confidential project materials unless they are necessary and you are entitled to provide them.

17.2. If you voluntarily provide a suggestion about the Service, you permit us to use and implement that suggestion without payment or attribution. This permission does not extend to ownership of your project files, personal information, or unrelated creative work included in a support request.

17.3. General support explanations do not constitute project-specific professional advice, certification, or a promise of a particular project result. We do not promise a particular response time or support service level unless expressly agreed or required by law.

18.1. We may maintain, correct, update, replace, limit, or discontinue the Service or an individual Tool for reasons including security, legal compliance, technical compatibility, correction of errors, prevention of misuse, development of the offering, or commercial sustainability.

18.2. We may apply reasonable limits on file size, stored volume, supported formats, account activity, AI requests, processing time, or other resource use. Relevant material limits will be disclosed before you commit to an affected offering. Changes affecting existing access or stored work remain subject to the notice and retrieval protections in these Terms and applicable law.

18.3. We do not promise uninterrupted operation, permanent availability of a particular Tool or version, compatibility with every environment, or implementation of a planned feature. Temporary interruptions may occur during maintenance, failures, or circumstances outside our reasonable control.

18.4. Where reasonably practicable, we will give advance notice of a material reduction or discontinuation affecting an ongoing offering. Urgent security, legal, or operational action may require a change or interruption without advance notice.

18.5. Changes remain subject to any existing contractual commitments and mandatory requirements concerning notice, continued conformity, cancellation, refunds, or other remedies. Where the law requires notice on a durable medium or a right to terminate, we will provide it.

18.6. We are not responsible for a delay or failure to perform to the extent it is caused by an event beyond our reasonable control that we could not reasonably prevent or overcome. We will take reasonable steps to limit its effect. This does not remove a statutory right to end an affected contract or obtain a remedy.

19.1. We may suspend or restrict access where reasonably necessary because of a material breach of these Terms, unlawful activity, a security risk, misuse of resources, infringement of rights, or a legal requirement. We may also end an offering in accordance with section 18.

19.2. Measures may include rejecting a file or request, quarantining or removing content, limiting AI use or uploads, disabling a sharing link or function, suspending an account, or blocking access. We will aim to make a restriction proportionate to the issue and consider its seriousness, repetition, and effect on other people. Urgent or serious threats may require immediate action.

19.3. Where lawful and reasonably practicable, we will explain the reason for a restriction and provide an opportunity to correct a remediable breach. We may withhold information where disclosure would compromise security, another person's rights, or a legal obligation. You may contact us if you believe a restriction was applied in error.

19.4. You may stop using the free Service at any time. Stopping use does not create a fee, but does not remove obligations or liabilities already arising from your previous use.

19.5. When access ends, your permission to access the affected Service ends. Rights in Outputs already lawfully obtained continue as stated in section 9, unless the particular Output was obtained unlawfully or its continued use infringes another person's rights. Provisions intended to continue, including ownership, liability, accrued claims, and dispute provisions, survive as applicable.

19.6. You may request account closure through the available account controls or by contacting contact@buildner.com. We may take reasonable steps to verify that you are entitled to close the account. Export materials you need before closure. Account closure does not transfer ownership of your materials to us, and the storage and deletion provisions continue to apply.

19.7. Content and abuse restrictions may be applied following a user report, a legal notice, security information, or checks associated with the feature you use. Where automated screening or decision-making is used, we will explain its role and the available review process in the relevant feature information or restriction notice, as required by law. These Terms do not promise that every Input, profile, or Output is checked, and do not treat passing a check as approval of its legality or accuracy.

19.8. Where required by law, we will provide a clear statement of the reasons for a content or account restriction, its scope and duration where known, the contractual or legal ground, the role of automation, and the means to challenge it. You may request review at contact@buildner.com. We will consider relevant information and provide human review where applicable law requires it. These arrangements do not limit any other available complaint or redress procedure.

20.1. The Service is supplied for the limited purposes described in these Terms and the relevant Tool. Subject to section 21.1 and mandatory law, it is provided on an “as is” and “as available” basis.

20.2. To the extent legally permitted, we give no additional warranty that the Service or an Output will be error-free, complete, continuously available, suitable for every particular purpose, compatible with every system, or capable of achieving a particular commercial, academic, design, printing, or regulatory result.

20.3. We do not guarantee that every defect, omission, duplicate, parameter conflict, model difference, coordination problem, unsupported IFC relationship or register issue will be detected or corrected, or that the Service will prevent loss, delay, rework or rejection of your materials.

20.4. For Business Users, and to the extent permitted by law, implied warranties, conditions, and terms concerning satisfactory quality, merchantability, fitness for a particular purpose, and non-infringement are excluded.

20.5. For Consumers, nothing in this section excludes statutory requirements concerning conformity, reasonable care and skill, security, remedies, or binding descriptions of the Service. Describing a Tool as free, experimental, or a preview does not remove rights that the law gives you.

21.1. Liability that is not excluded. Nothing in these Terms excludes or limits liability for fraud, fraudulent misrepresentation, wilful misconduct, gross negligence, death or personal injury caused by negligence, or any other liability to the extent its exclusion or limitation is prohibited by applicable law. Nothing removes a non-excludable consumer right, statutory remedy, or right to compensation. This section takes priority over every exclusion, limitation, and indemnity in these Terms.

21.2. Matters outside our responsibility. Subject to section 21.1, we are not responsible for loss to the extent it results from inaccurate or unauthorised Inputs, use contrary to clear Tool instructions, changes made by you or an independent third party, or decisions for which the Service does not undertake responsibility. This does not exclude responsibility for our own breach or an error for which we are legally liable.

21.3. Business losses excluded. For Business Users, and to the fullest extent permitted by law, we are not liable for indirect, consequential, special, exemplary, or punitive loss, or for loss of profits, revenue, business, contracts, anticipated savings, opportunity, goodwill, or reputation. We are also not liable for loss or corruption of data, loss of use, business interruption, or wasted expenditure, whether those listed losses are direct or indirect.

21.4. Project and production consequences for Business Users. Subject to section 21.1, the business exclusions include losses from missed coordination or submission deadlines, rejected deliverables, reissued drawing packages, incorrect ordering, fabrication or construction errors, rectification, undetected clashes, inaccurate quantities, model or coordinate misalignment, project delay, and claims by your clients or contractors arising from reliance on an Output. These exclusions apply even if the possibility of the relevant loss was brought to our attention, to the extent permitted by law.

21.5. Business liability cap. Subject to section 21.1, our total aggregate liability to a Business User for all claims arising from or relating to the Service and these Terms is limited to the greater of EUR 100 and the fees that Business User paid us for the affected features of this Service during the 12 months immediately before the event giving rise to the first claim. For a series of related events, the first event is used. Fees paid for separate Buildner services are not included. This limit applies collectively across contractual, tort, negligence, statutory, and other claims to the extent the law permits.

21.6. Consumers. The business exclusions and cap in sections 21.3–21.5 do not apply to Consumers. Our responsibility to Consumers is determined by applicable law. Where the law permits a limitation by reference to foreseeability, we are responsible for loss that is a foreseeable result of our breach or failure to exercise the care and skill required by law, and are not responsible for loss that was not reasonably foreseeable. All mandatory rights to repair, correction, price reduction, refund, termination, or compensation remain available where applicable.

21.7. Avoidable loss and contribution. Each party must take reasonable steps to reduce a loss where the law requires it. Liability may be reduced to reflect the other party's contribution to a loss to the extent permitted by law. No clause reverses a statutory burden of proof or makes a Consumer responsible for our breach.

22.1. This section applies only to Business Users. To the extent permitted by law, you will indemnify us against reasonably incurred losses, liabilities, and reasonable legal costs resulting from a third-party claim to the extent caused by your material breach of these Terms, unlawful use of the Service, or Inputs that infringe the third party's rights.

22.2. This obligation does not apply to the extent a claim is caused by our breach, negligence, misconduct, or an alteration or use of your Inputs that you did not authorise. It does not make you responsible merely because a third party alleges wrongdoing.

22.3. We will give reasonably prompt notice of the claim, allow reasonable participation in its defence, and take reasonable steps to mitigate loss. You are not required to fund a settlement entered into without your consent, which must not be unreasonably withheld. No settlement may impose an admission, non-monetary obligation, or restriction on either party without that party's agreement.

22.4. Consumers are not subject to this contractual indemnity. Any responsibility they have for unlawful conduct or loss they cause is determined by applicable law.

23.1. Contact us using section 27 if you have a complaint, encounter a material error, believe your access was wrongly restricted, discover a security issue, or consider that material stored or made available through the Service is illegal or infringes your rights. You may also use a reporting control offered for the relevant feature.

23.2. To help us investigate, identify the relevant page, Tool, profile, file, or content location; describe the issue and why you consider it unlawful or otherwise objectionable; and provide a way to contact you. For a rights complaint, identify the protected material and explain your authority to act. For a technical error, include the approximate time and relevant settings. Submit reports in good faith, state that the information is accurate to the best of your knowledge, and share only what is necessary. Any legal exception to a requirement to identify yourself remains available.

23.3. If you discover a vulnerability, stop any activity that risks harm or unauthorised access and report it privately. Do not access another user's materials, extract data, or disrupt the Service to demonstrate the issue. A report does not itself authorise further security testing.

23.4. We will consider complaints and notices in good faith and respond as required by applicable law. We may request reasonably necessary information and take proportionate action, including correcting a Tool or restricting disputed material.

23.5. Contacting us is encouraged but is not a mandatory condition before exercising a legal right, making a regulatory complaint, seeking urgent relief, or starting proceedings. These Terms do not shorten a statutory limitation period.

23.6. Where applicable law requires it, we will acknowledge a content notice, communicate the resulting decision and available review options, and provide the legally required information about automated processing of that notice. Do not knowingly submit false reports or use the complaints process to harass another user.

24.1. We may update these Terms to reflect changes to the Service, business arrangements, applicable law, security requirements, or identified drafting errors. We will publish the revised wording with an updated date.

24.2. For a material change affecting an ongoing relationship, we will give reasonable advance notice through the Site or another appropriate channel, and obtain fresh acceptance where required by law. An urgent legal or security change may take effect sooner where permitted and necessary; we will explain it as soon as reasonably practicable.

24.3. Changes apply prospectively. They do not retrospectively impose a fee, transfer ownership of your existing Inputs or Outputs, remove an accrued claim, or rewrite a completed purchase.

24.4. If you do not agree to a revised version, stop using the affected Service before it takes effect. Continued use constitutes acceptance only where you have received legally sufficient notice and applicable law permits that method of acceptance. Rights concerning cancellation, refunds, or termination of an existing paid arrangement remain unaffected.

24.5. Introducing paid access remains subject to section 4. Posting revised Terms alone does not authorise us to charge you.

25.1. These Terms and disputes relating to the Service are governed by the laws of the Principality of Andorra, subject to mandatory rules that apply regardless of a choice of law.

25.2. If you are a Consumer, this choice does not deprive you of mandatory protections available under the law that would otherwise apply, including protections of your country of habitual residence where applicable.

25.3. For Business Users, the competent courts of Andorra have exclusive jurisdiction over disputes relating to these Terms or the Service, except where a mandatory rule requires otherwise.

25.4. Consumers may bring proceedings in any court available to them under mandatory law, including the courts of their place of residence where applicable. We will bring proceedings against a Consumer only in a court permitted by applicable law.

25.5. These Terms do not impose mandatory arbitration, waive a right to participate in proceedings where that right is protected by law, or restrict your right to complain to a competent public authority.

26.1. Entire agreement for this Service. These Terms, properly notified Tool-specific terms, and any express written agreement for this Service form the agreement concerning this Service. They do not replace contracts for other services or exclude a statement or representation that applicable law makes binding.

26.2. Severability. If a provision is invalid or unenforceable, it will not apply to the extent of that invalidity, and the remainder continues where legally possible. An unfair consumer term will not be rewritten merely to make an otherwise unlawful restriction enforceable.

26.3. No waiver. A failure or delay in enforcing a provision does not waive the right to enforce it later. A waiver of a particular breach does not waive a later breach.

26.4. Transfer. You may not transfer a licence to access the Service without our permission, except where the law permits it. We may transfer our rights and obligations as part of a lawful reorganisation or transfer of the Service, provided this does not reduce your mandatory rights or the guarantees owed to you. We will give notice where required.

26.5. No partnership or agency. These Terms do not create a partnership, employment, agency, or joint venture. Neither party may commit the other to obligations without authority.

26.6. Communications. We may provide Service notices electronically where the law permits. This does not amount to consent to marketing. Formal notices must use a method and address permitted by applicable law.

26.7. Language. These Terms are issued in English. If a translation is provided, applicable consumer-language requirements and legal rules on interpretation continue to apply; this clause does not override them.

Please identify Buildner BIM Tools and the relevant Tool in your message so that it can be directed to the appropriate team.

28.1. Some Tools may expose supported browser-assistant actions, including an optional browser tool interface. Availability depends on the Tool and browser. Those actions are provided for your authorised use of that Tool, within its stated limits, and do not create an unrestricted public API or a right to bulk-extract Service materials.

28.2. Depending on the supported action, an assistant may supply Inputs, start a check, update the visible working state, or receive a result or report summary. Other browser extensions or assistants you authorise may also be able to read visible page content. Review their permissions, intended actions and applicable privacy terms before sharing client or restricted project information. The local-processing statement in section 8 does not state that a separately authorised assistant keeps all information on your device.

28.3. Permission to use a browser assistant does not authorise it to submit project content to a remote provider contrary to your client, employer or other obligations. Review its proposed Inputs and actions and verify its reported completion against the actual Tool state and exported files. An assistant’s statement that a check passed is not a substitute for inspecting that check.

28.4. Assistant support differs between Tools. Some actions accept only caller-supplied data; others may return information about the current result. Do not assume every Tool exposes previously imported files or that all Tools have the same capabilities. The descriptions and permissions of the actual integration govern the actions available.

28.5. An assistant, add-on or integration does not enlarge the Tool’s scope, certify its results, override access restrictions, grant permission to act for another person, or relieve us of an obligation imposed on us by law. Any future direct connection to an authoring platform or common data environment must identify the relevant access and processing before you choose to connect it.

This schedule forms part of the Terms. It describes the current BIM tools by function. A renamed Tool performing the same function remains subject to the relevant description when it is offered under these Terms. Only the features expressly available in the Tool are supplied. Follow its current format, size and instruction limits. These provisions supplement sections 7–13 and do not override mandatory rights or an express binding commitment.

A. What changed? — Schedule comparison

A.1. This Tool compares two exported tables using the selected identity columns and fields. It reports records and values as added, removed, changed or unchanged within that supplied information. It does not inspect model geometry, unexported parameters, linked files or model history.

A.2. Identifiers are trimmed and treated as case-sensitive strings, retaining leading zeros. Missing or duplicate identifiers prevent a reliable one-to-one comparison and must be addressed as the interface requires. A changed identifier can appear as one removal and one addition even where the same physical element continues to exist.

A.3. Header matching and optional value normalisation may ignore differences you would otherwise consider significant. Numeric-format comparison is not unit conversion. Missing columns and empty cell values can represent different conditions. Check the matching, selected fields and normalisation settings against the purpose of your review.

A.4. The change export includes the detected changes regardless of display search or filters. “Unchanged” means that the compared exported values match under those settings; it is not a whole-model change certificate or confirmation that nothing relevant changed elsewhere.

B. Room check

B.1. This Tool compares a supplied room brief with an exported room schedule using the selected room identifier or name, area units, requirement type and tolerance. It does not measure room geometry, read the full model or verify a PDF brief, regulatory schedule or statutory floor-area measurement.

B.2. Name or identifier matching normalises case and extra spaces but retains leading zeros. Duplicate matching keys require review; the Tool does not decide the intended room pairing. Check whether a brief row represents one room, a room type, a quantity or a department before supplying it to a one-room-per-row comparison.

B.3. A target-area test considers both the upper and lower tolerance bounds; a minimum-area test considers the lower bound. The bounds are inclusive. A minimum supplied by you is not independently verified as a regulatory minimum. Confirm the area units for each schedule and the intended tolerance.

B.4. Missing or extra rooms remain review matters even if an overall total appears acceptable. Totals can include valid areas from duplicate or extra records and are not a substitute for record-level review. A favourable room result does not establish adequate occupancy, accessibility, circulation, daylight, ventilation, fire safety, usable dimensions or suitability for the intended activity.

C. Door check

C.1. This Tool checks an exported door schedule for matters such as duplicate marks, missing mapped fields, non-positive or invalid dimensions, differences within a door type and optionally missing fire-rating information. It does not read the native door geometry or carry out building-code or fire-engineering assessment.

C.2. Dimension units must be selected correctly. A positive width or height is not evidence of required clear opening, escape capacity, accessible clearance or the installed construction. A mark is checked for uniqueness across the supplied schedule, including levels; a repeated mark may require a project-specific explanation.

C.3. Fire-rating information is checked as supplied text. Labels that look similar are not certified as equivalent fire classifications, and a populated fire-rating field is not proof of a tested assembly, certification, installation or compliance. The Tool does not evaluate smoke control, hardware, swing direction, operating forces, door closers, ironmongery, acoustic performance or all relevant standards.

C.4. A type conflict identifies inconsistent source information without deciding which value is correct. Review source rows, authoring families and instance overrides, and consult the responsible designer or specialist before ordering or changing an assembly.

D. Missing data

D.1. This Tool checks whether the required columns and values you select are present within the chosen category scope. Blank cells, whitespace, configured placeholder markers and absent required columns may count as missing. Zero and false count as present unless your placeholder rules specify otherwise.

D.2. Presence does not establish truth, plausibility, units, a valid classification, an appropriate specification or compliance with information requirements. Required fields are defined by your choices; the Tool does not discover every project obligation or determine whether a field is required for a particular delivery stage.

D.3. Each record is checked independently. Repeated identifiers remain separate source records and are not automatically evidence of unique real-world elements. A completeness percentage relates only to the selected requirements and checked scope, not the entire model or every discipline.

D.4. Display filters do not reduce the exported issue scope described by the Tool. “No missing values” means none were found under the selected settings; it does not confirm that source values are correct or that omitted categories and records meet the same requirements.

E. Parameter Match

E.1. This Tool compares supplied parameter definitions using GUIDs, names and available definition fields. Supported shared-parameter text files and delimited tables are interpreted as definitions, not as access to a live authoring model.

E.2. A GUID match confirms only the supplied shared-parameter identity. It does not independently establish compatible values, correct binding, valid project use or suitability for replacing another parameter. A name match alone does not establish identical parameter identity. Missing GUIDs or data types remain unconfirmed.

E.3. Instance values, formulas, non-shared parameters, omitted category bindings and other information not supplied in a supported form are outside the check. Optional group and binding comparisons concern only the fields actually available. Different export conventions or application versions can require manual interpretation.

E.4. Review proposed changes in the authoring application and test their effects before replacing definitions or migrating values. Parameter replacement may affect schedules, tags, formulas, family behaviour and downstream systems that this comparison does not inspect. Source-row references may refer to parsed records rather than physical text-file lines, as described by the Tool.

F. Alignment check

F.1. This Tool diagnoses differences between three corresponding XYZ control-point pairs using the units and tolerance you enter. It calculates original separations and a horizontal least-squares similarity fit with rotation, uniform scale and translation diagnostics. It does not parse or modify an RVT or IFC model.

F.2. The method fits horizontal rotation and uniform scale in the XY plane, derives translation from the selected points and applies the scale to Z. It is not a general three-axis rotation solution, geodetic transformation, survey adjustment or verification of the whole model. A small fitted residual can conceal a significant original offset or an unrepresentative choice of control points.

F.3. You must select genuinely corresponding, suitably distributed points and interpret each coordinate frame consistently. Collinear, repeated, mirrored, nearly degenerate or poorly measured points can make a fit unreliable or misleading. A reported mirror condition or degeneracy requires independent investigation.

F.4. A scale or offset diagnostic is not an instruction to rescale or reposition a production model. Check project origins, units, survey control, linking methods and the consequences for other disciplines with an appropriately qualified person. Additional independent control points and the full model may reveal problems that three pairs do not detect.

G. IFC check

G.1. This Tool reads supported plain STEP IFC exports and checks selected metadata and relationships, including configured class totals, storey names, required-property presence, element names, spatial relationships, duplicate or malformed GlobalIds and certain missing references. The current reader supports the stated IFC2x3 and IFC4 forms; unsupported variants, including IFCZIP, IFCXML and IFC4.3, are outside this reader’s current scope.

G.2. This is a partial information check. It does not validate model geometry, clashes, unit assignments, coordinates, every classification, all EXPRESS rules, every relationship or the correctness of property values. A successfully read file or favourable result is not full IFC conformance, buildingSMART certification, Information Delivery Specification validation or proof of interoperability with another application.

G.3. Counts use the categories and exclusions stated by the Tool. Element totals may differ from totals in another application because of type definitions, openings, feature elements, virtual elements, annotations or spatial entities. Confirm that the expected count is based on the same scope and schema treatment.

G.4. Property presence can consider occurrence values and supported assigned-type values, with occurrence values taking precedence as described. Property names are case-sensitive. Zero and false can be valid present values. Recognising a reference or a nested value does not verify its substantive accuracy or resolve every referenced object.

G.5. Storey or containment findings require context: some elements can legitimately lack the storey relationship expected for ordinary building components. The Tool does not determine whether every warning is a schema violation. Visible affected-element lists may be shortened for display while the export includes the full identified list. An empty export, unsupported entity or incomplete model must not be treated as a successful full review.

H. Warning sorter

H.1. This Tool groups warning records from supported text, table or recognised HTML reports and provides editable suggested priorities, actions and review statuses. It does not connect to the authoring model, inspect geometry, clear warnings or perform repairs.

H.2. Suggested priorities are workflow aids based on recognised message patterns and available report information. They are not a professional risk assessment or an instruction to ignore a warning. Language, version, message wording and report layout can affect recognition; non-English text may be retained without matching the English priority rules.

H.3. Similar messages do not prove identical causes or consequences. Review the original records, relevant element identifiers and model context before assigning a priority, deleting geometry, changing constraints or making another correction. Unsupported HTML layouts may need to be re-exported as a supported table.

H.4. Marking a group reviewed records a user action and does not mean the warning has been resolved. The CSV retains the source records with the stated grouping and status information. Re-export warnings from the revised model and review them independently to confirm a fix.

I. Ready to issue? — Drawing package check

I.1. This Tool checks the supplied drawing register for missing required information, duplicate drawing numbers and inconsistencies with selected revision or issue-status requirements. It reviews register metadata, not the contents of the drawings or completeness of the physical or digital issue package.

I.2. A favourable result does not establish that drawings exist, open correctly, carry valid signatures, match the register, contain coordinated design information, use the intended revision, or have received contractual or regulatory approval. It does not verify linked documents, transmittals, recipient lists or permissions in a common data environment.

I.3. Set revision and status requirements to reflect the intended issue. Where a requirement is left unrestricted, mixed non-empty values may not breach that particular check. Project-specific codes and acceptable mixed-revision packages need human interpretation; the Tool does not impose a universal revision or suitability-code scheme.

I.4. “Ready to issue?” is the Tool’s name and a question for your review. Neither that name nor a “clear” result authorises issue, constitutes professional sign-off, changes a document’s contractual status or sends the package. Complete your organisation’s approval and formal transmission process independently.

J. Issue pack

J.1. This Tool helps you write and organise coordination issues with descriptions, owners, dates, priorities, statuses and optional snapshots. It supports the stated imports and local CSV, printable/PDF and editable-pack outputs. It does not detect all clashes, interrogate the model, manage a hosted issue database or synchronise with another platform unless a separate feature expressly does so.

J.2. An owner, due date, priority or status is user-entered project information. Entering it does not notify that person, obtain their agreement, serve contractual notice, allocate legal liability, amend a project appointment or prove completion. You must separately communicate and agree actions through the appropriate project channels.

J.3. Snapshots are static illustrations and may omit model context, hidden geometry, orientation, scale, location or later changes. A screenshot is not proof of the current or actual condition. Check visibility and confidential information before including snapshots in a report. Image conversion may affect resolution or metadata and is not a certified anonymisation service.

J.4. Review filters affect the printable/PDF pack; CSV and editable packs include all issues as described by the Tool. The single-issue preview is not the complete exported pack. Check the output, page breaks, omitted resolved issues, ordering and attached images before issuing it. Printing or saving PDF uses your browser’s settings and capabilities.

J.5. An editable pack is a local file you must save and retain. It can include unfinished issues and embedded snapshots. Loading a pack or importing issues may replace current working content, subject to the Tool’s controls. A CSV or PDF is not necessarily a complete substitute for the editable file and may not preserve all editable information or images.

J.6. An issue identifier or editable pack is not automatically a BCF package, live model viewpoint, verified document record or interoperable project exchange. Do not assume another application can reconstruct the underlying model context or import every field. A resolved status must be supported by the appropriate model check and project agreement.
