Let&#8217;s say pipes cutting through beams, HVAC clashing with lighting, or trades walking off-site due to misaligned timelines. The root of these issues? A lack of structured BIM clash detection. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Without a proactive approach, these problems sneak into construction phases. Then, blowing out budgets and pushing timelines into chaos. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Even when <a href=\"https:\/\/interscale.com.au\/blog\/what-is-bim\/\">Building Information Modeling (BIM)<\/a> is adopted, it\u2019s often too late in the game, leaving little room for strategic coordination.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At Interscale, we&#8217;ve witnessed how getting BIM clash detection right really changes the game. Yes, you can turn a reactive firefighting approach into proactive quality management. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Let&#8217;s walk through how you can make this work for you.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Is_BIM_Clash_Detection\"><\/span>What Is BIM Clash Detection?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">BIM clash detection is the process of identifying and resolving physical or functional conflicts within a building model, before they become real-world problems. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The idea is prevention at scale. A clash is where two building elements, let&#8217;s say, a duct and a beam, shouldn&#8217;t occupy the same space, but do. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Sometimes, the problem is subtler, like when a maintenance path around equipment is too tight. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Either way, finding BIM clash issues early means you can resolve them in the virtual space rather than during construction. All to saving time, cost, and stress.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The processes above are powered by BIM clash detection software. The software checks for overlapping components, inadequate clearances, and sequencing errors within 3D models. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Who&#8217;s in charge of the clash detection process? Typically falls to <a href=\"https:\/\/interscale.com.au\/blog\/what-is-a-bim-coordinator\/\">BIM coordinators<\/a> or managers, professionals skilled in tools like Navisworks or Solibri. In some cases, an external consultant can be the one in charge.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The benefits of BIM clash detection are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Significant reduction in errors and costly rework<\/li>\n\n\n\n<li>Substantial time and cost savings through early conflict resolution<\/li>\n\n\n\n<li>Enhanced cross-disciplinary collaboration and communication<\/li>\n\n\n\n<li>More accurate project timelines and sequencing<\/li>\n\n\n\n<li>Streamlined construction processes and increased productivity<\/li>\n\n\n\n<li>Improved site safety through advance identification of hazards<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_Is_Clash_Detection_Critical_in_AEC_Projects\"><\/span>Why Is Clash Detection Critical in AEC Projects?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Clash detection is critical in AEC projects because coordination problems usually show up before teams realise the model can no longer be trusted.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"538\" src=\"https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2025\/04\/image-1024x538.png\" alt=\"bim clash detection\" class=\"wp-image-11507\" title=\"\" srcset=\"https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2025\/04\/image-1024x538.png 1024w, https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2025\/04\/image-300x157.png 300w, https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2025\/04\/image-768x403.png 768w, https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2025\/04\/image-1536x806.png 1536w, https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2025\/04\/image.png 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">That is why the process of clash detection in BIM matters beyond geometry because the issue is not only whether two elements collide.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The issue is whether the model is still reliable enough for review, issue, sequencing, pricing, and handover. That\u2019s where the impact starts to show up, often earlier than expected:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Coordination can fail before a hard clash appears: Once information control slips, BIM coordination weakens well before the most obvious clash is visible.<\/li>\n\n\n\n<li>A model can look usable and still carry delivery risk: A duct through a beam is easy to spot. The harder problem is a model that appears coordinated, but still carries access, clearance, or timing problems that force another round of checking later.<\/li>\n\n\n\n<li>Small model gaps quickly become project control problems: The structure may update after services has already been reviewed for the week\u2019s package. Or the geometry may clear while maintenance access still fails. Or the clash report may be complete, but still too unclear to support the next site-facing decision.<\/li>\n\n\n\n<li>Once trust drops, coordination gets slower and more expensive: This is where BIM clash analysis becomes a delivery control task. Teams start revalidating information, issue ownership gets blurred, and approval timing becomes harder to manage.<\/li>\n\n\n\n<li>Software decisions carry commercial weight: The software pricing does not decide the software mix by itself, but it does show why role coverage, coordination scope, and software planning need to be considered together.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Types_of_Clashes_in_BIM\"><\/span>Types of Clashes in BIM<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Knowing the different types of clashes in BIM can help your teams sort, prioritise, and fix the conflicts that pop up. Generally, we group them into three main buckets:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Hard Clashes: <\/strong>The clash occurs when two components physically intersect. Think of a duct running straight through a concrete beam. These clashes are typically the easiest to detect. You can use BIM clash detection software, and are often resolved early in the process.<\/li>\n\n\n\n<li><strong>Soft Clashes (Clearance Clashes): <\/strong>These occur when there\u2019s not enough space between elements, even if they don\u2019t touch. For example, if a water heater doesn\u2019t have the required clearance for servicing. Or maybe a pipe is too close to the insulation. These require custom rule sets in your clash detection platform to find.<\/li>\n\n\n\n<li><strong>Workflow Clashes (4D\/Sequencing Clashes): <\/strong>These relate to project timing and logistics. Installing drywall before the cables go in? That\u2019s a workflow clash. By linking models with the project schedule, what we call 4D modelling, you can simulate construction sequences and spot timing conflicts before they become costly errors.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"BIM_Clash_Detection_Software\"><\/span>BIM Clash Detection Software<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Finding BIM clashes hinges on the right tools, and there\u2019s no shortage of BIM clash detection software to choose from. Here are the go-to platforms our team at Interscale works with:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Autodesk Navisworks Manage: <\/strong>The gold standard for model aggregation and clash detection. It brings together files from Revit, ArchiCAD, Tekla, and more into a federated model.<\/li>\n\n\n\n<li><strong>Revit: <\/strong>While it\u2019s primarily a BIM design modelling tool, Revit has its own interference check. This lets designers do initial Revit clash detection within their work before the formal BIM coordination.&nbsp;&nbsp;&nbsp;<\/li>\n\n\n\n<li><strong>Solibri Model Checker: <\/strong>Known for its smart, rule-based BIM model checking, Solibri goes beyond basic clashes. Solibri is great for complex soft clashes and code compliance.<\/li>\n\n\n\n<li><strong>Autodesk Construction Cloud (ACC)\/BIM 360: <\/strong>With its Model Coordination module, ACC allows multiple teams to publish and review models in a shared space. This approach is so perfect for collaborative clash management.<\/li>\n\n\n\n<li><strong>Revizto: <\/strong>Popular for visual issue tracking and communication, tightly integrated with clash coordination workflows.<\/li>\n\n\n\n<li><strong>Trimble Connect &amp; ClashMEP:<\/strong> Trimble brings solid cross-disciplinary support. Meanwhile, ClashMEP focuses on specific system conflicts, like mechanical and electrical.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Choosing the right BIM clash detection software depends on your project\u2019s complexity and team setup. And each tool has its sweet spot. Platforms like Navisworks and ACC are common, but being able to work across different software is still important. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_BIM_Clash_Detection_Works\"><\/span>How BIM Clash Detection Works?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">BIM clash detection works by combining discipline models into one review environment, testing where systems conflict, then turning those findings into coordinated fixes before they affect documentation, procurement, or site work.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"551\" src=\"https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2025\/04\/image-1-1024x551.png\" alt=\"\" class=\"wp-image-11508\" title=\"\" srcset=\"https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2025\/04\/image-1-1024x551.png 1024w, https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2025\/04\/image-1-300x161.png 300w, https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2025\/04\/image-1-768x413.png 768w, https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2025\/04\/image-1.png 1260w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">In practice, the workflow of BIM clash detection is not complicated at a basic level:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Bring the models together by combining architectural, structural, and services models into one federated environment so each discipline can be checked against the others rather than reviewed in isolation.<\/li>\n\n\n\n<li>Confirm the shared setup by checking coordinates, levels, naming, and model versions first, because clash detection in BIM becomes unreliable quickly when the underlying model conditions are already out of sync.<\/li>\n\n\n\n<li>Run the clash tests to identify physical overlaps, clearance problems, or sequencing conflicts that could affect constructability, access, or delivery timing.<\/li>\n\n\n\n<li>Review the results properly so the team can separate real coordination issues from false positives instead of treating every detected clash as equally important.<\/li>\n\n\n\n<li>Judge which clashes matter most by focusing BIM clash analysis on the issues that affect design decisions, service access, sequencing, or buildability.<\/li>\n\n\n\n<li>Assign clear ownership so each live issue sits with the right discipline lead, modeller, or BIM coordinator before the next review cycle starts.<\/li>\n\n\n\n<li>Update and retest the model because the process of BIM clash detection only works when closure is verified in the model rather than assumed in a meeting.<\/li>\n\n\n\n<li>Carry unresolved clashes forward with clear status and accountability so they do not quietly disappear while the project continues moving.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"543\" src=\"https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2025\/04\/image-2-1024x543.png\" alt=\"\" class=\"wp-image-11509\" title=\"\" srcset=\"https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2025\/04\/image-2-1024x543.png 1024w, https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2025\/04\/image-2-300x159.png 300w, https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2025\/04\/image-2-768x407.png 768w, https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2025\/04\/image-2-1536x814.png 1536w, https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2025\/04\/image-2.png 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">But please note that the setup matters more than teams sometimes expect. If the wrong model version is loaded, if disciplines are not using the same coordinates, or if naming is inconsistent, the clash report becomes harder to trust before the team has even started resolving anything.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When design coordination starts without a shared model setup, discipline models may not sit in the same location, may use different storey names and settings, or may carry incomplete project information, and once that happens, clash review becomes less reliable from the start.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Software choice starts to matter after those fundamentals are in place. Revit clash detection is useful for early author-side checking inside the model, but broader clash detection in BIM becomes more effective once multiple discipline models are reviewed together in a federated BIM coordination environment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, let&#8217;s say you have an education project, then the architect can clear internal interference checks and still miss the real issue until hydraulic, fire, and mechanical models are tested together.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Or in your Melbourne industrial project, the geometry may look valid at object level but still create a sequencing problem once installation logic is tested against how trades need to move through the space.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Best_Practices_for_Effective_BIM_Clash_Detection\"><\/span>Best Practices for Effective BIM Clash Detection<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">While <a href=\"https:\/\/interscale.com.au\/blog\/bim-software-list\/\">BIM software<\/a> is crucial, effective BIM clash detection requires a structured process, clear communication, and adherence throughout the project lifecycle. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For us, a good structured process of BIM clash detection starts early in the design phase. Run checks regularly (say, weekly) alongside model updates.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Regular <a href=\"https:\/\/interscale.com.au\/blog\/bim-coordination\/\">BIM coordination<\/a> meetings are key. Then, set clear rules upfront. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Also, you need to define tolerances for soft clashes, like maintenance clearances or code requirements, to avoid drowning in irrelevant alerts. This cuts down the noise and hones in on what matters.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Then, federate models systematically and properly. All to ensure all disciplines\u2019 inputs align in a single and coordinated model. Use consistent coordinates, naming conventions, and ensure the latest versions are included. From there, you need to run clash tests strategically. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Prioritise critical systems, like structural vs. MEP, before sweating the small stuff. Review results carefully, filtering out noise and creating clear BIM clash detection reports with visuals to pinpoint issues.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Assign ownership for each clash and track resolutions using software tools. Integrate this with broader BIM model checking to ensure data-rich, accurate models. This is where a thorough <a href=\"https:\/\/interscale.com.au\/blog\/bim-audit\/\">BIM audit<\/a> can make all the difference. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It highlights structural inconsistencies or outdated elements that could otherwise disrupt clash detection workflows. Collaboration is key here. You need to use coordination meetings to hash out complex clashes and keep everyone aligned.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These steps turn clash detection into a proactive quality control tool. And that\u2019s how we do it at Interscale.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Common_Challenges_in_Clash_Detection\"><\/span>Common Challenges in Clash Detection<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The common challenges in clash detection below tend to look small at first, but once they start stacking up, they slow coordination, reduce trust in the model, and make it harder to move forward with confidence:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Hidden or non-visible elements still trigger clashes, which confuses reviewers and forces teams to double-check whether the issue is real before they can act on it.<\/li>\n\n\n\n<li>Some interferences are missed altogether, especially in IFC-based models with structural framing, which creates a false sense that coordination is already complete.<\/li>\n\n\n\n<li>Manual review effort grows too quickly, pulling time away from resolving real coordination risks and into checking whether the model can be trusted in the first place.<\/li>\n\n\n\n<li>Clash data becomes too noisy to act on, so teams spend more time filtering results than actually fixing issues that affect constructability or access.<\/li>\n\n\n\n<li>Teams struggle to agree what actually matters, which means minor clashes get attention while more critical coordination risks are delayed.<\/li>\n\n\n\n<li>Issue ownership becomes unclear across disciplines, making it harder to close clashes before the next review cycle and leaving problems to carry forward.<\/li>\n\n\n\n<li>Unresolved clashes slip through to later stages, increasing the chance that coordination gaps reach documentation, procurement, or site work.<\/li>\n\n\n\n<li>Coordination confidence drops even when reports exist, because the team can see the clashes but cannot clearly link them to the next decision or package.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Should_You_Outsource_BIM_Clash_Detection\"><\/span>Should You Outsource BIM Clash Detection?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">You should outsource BIM clash detection when the project needs tighter coordination discipline than your internal team can sustain without slowing delivery, weakening model confidence, or stretching key people too thin.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2025\/04\/image-3-1024x546.png\" alt=\"bim clash detection services\" class=\"wp-image-11510\" title=\"\"><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">In practice, the shift usually becomes clear when a few conditions start repeating across projects:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Consultant models arrive in mixed formats and need normalising before review, which adds setup overhead before coordination can even begin.<\/li>\n\n\n\n<li>The internal BIM lead is only partly available, so clash detection in BIM becomes inconsistent rather than a steady weekly process.<\/li>\n\n\n\n<li>Clash meetings are happening, but the close-out rhythm is unstable, meaning issues are discussed but not consistently resolved in the model.<\/li>\n\n\n\n<li>Project managers want clearer reporting, but the authoring team does not have time to structure and track issues at that level.<\/li>\n\n\n\n<li>The team can detect clashes but cannot consistently turn them into accountable resolution, which is where BIM clash analysis starts losing real project value.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">At that point, the decision is less about in-house versus outsourced preference, and more about whether the coordination workload now needs dedicated ownership, a steadier cadence, and clearer accountability than the current setup can provide.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, in 10-30 person firms, this often shows up when the technical capability exists, but no one has enough uninterrupted time to run the process of BIM clash detection properly each week.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In larger consultant teams across Sydney and Melbourne, the pressure usually comes from keeping coordination aligned across different publishing cycles, package deadlines, and discipline priorities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That is where structured <a href=\"https:\/\/interscale.com.au\/services\/bim-services\/clash-detection\/\">BIM clash detection services<\/a> from Interscale can help your teams.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Instead of just running clash tests, Interscale focus is on building a consistent coordination layer across the project. Models are properly federated, clash rules are applied with intent, issue ownership is clearly assigned, and close-out is tracked so nothing drops between review cycles.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Whether you\u2019re setting up your first federated model or fine-tuning clash rules across multiple consultants, we\u2019re happy to discuss it. <a href=\"https:\/\/interscale.com.au\/contact-us\/\">Start by booking a free BIM coordination session with Interscale here.<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Your_Next_Steps\"><\/span>Your Next Steps<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">BIM clash detection is the difference between catching design flaws in a model and scrambling to fix them on-site. So, don\u2019t let clashes derail your next project. If your current process still feels reactive or if clashes are slipping through the cracks, it\u2019s time for a reset.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"FAQ\"><\/span>FAQ<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<div class=\"wp-block-aab-accordion-block aab__accordion_container  accessibilityOn\" style=\"margin-top:0px;margin-bottom:15px;border:1px solid #bcb6b638\" id=\"aab_accordion_e138c6f0_0\" role=\"button\" aria-expanded=\"false\" tabindex=\"0\"><div class=\"aab__accordion_head aab_right_icon \" style=\"background-color:#bcb6b638;border-top:none;border-right:none;border-bottom:none;border-left:none\"><div class=\"aab__accordion_heading aab_right_icon aab_right_link\"><div class=\"head_content_wrapper\"><div class=\"title_wrapper\"><h3 class=\"aab__accordion_title\" style=\"margin:0\"><span class=\"ez-toc-section\" id=\"What_is_the_Best_Software_for_Clash_Detection\"><\/span><strong>What is the Best Software for Clash Detection?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3><\/div><\/div><\/div><div class=\"aab__accordion_icon\" style=\"border:0px solid transparent\"><span class=\"aab__icon dashicons dashicons-plus-alt2\" style=\"font-size:23px\"><\/span><\/div><\/div><div class=\"aab__accordion_body  \" role=\"region\" style=\"display:none;border-top:1px solid #bcb6b638;border-right:none;border-bottom:none;border-left:none\"><div class=\"aab__accordion_component\">\n<p class=\"wp-block-paragraph\">There are a lot of best software for clash detection for Australia AEC industry, like Revit, Navisworks Manage, or Autodesk AEC Collection.

A more commercially relevant example is a soft clash where equipment technically fits in the plant room, but there is not enough clearance left for safe service access. Another example is a workflow clash where one trade is sequenced to install before the space or supporting system is actually ready.<\/p>\n<\/div><\/div><\/div>\n\n\n\n<div class=\"wp-block-aab-accordion-block aab__accordion_container  accessibilityOn\" style=\"margin-top:0px;margin-bottom:15px;border:1px solid #bcb6b638\" id=\"aab_accordion_e138c6f0_0\" role=\"button\" aria-expanded=\"false\" tabindex=\"0\"><div class=\"aab__accordion_head aab_right_icon \" style=\"background-color:#bcb6b638;border-top:none;border-right:none;border-bottom:none;border-left:none\"><div class=\"aab__accordion_heading aab_right_icon aab_right_link\"><div class=\"head_content_wrapper\"><div class=\"title_wrapper\"><h3 class=\"aab__accordion_title\" style=\"margin:0\"><span class=\"ez-toc-section\" id=\"Can_Revit_detect_clashes\"><\/span><strong>Can Revit detect clashes?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3><\/div><\/div><\/div><div class=\"aab__accordion_icon\" style=\"border:0px solid transparent\"><span class=\"aab__icon dashicons dashicons-plus-alt2\" style=\"font-size:23px\"><\/span><\/div><\/div><div class=\"aab__accordion_body  \" role=\"region\" style=\"display:none;border-top:1px solid #bcb6b638;border-right:none;border-bottom:none;border-left:none\"><div class=\"aab__accordion_component\">\n<p class=\"wp-block-paragraph\">Revit can detect clashes, but it is more useful as an early checking layer than as the whole coordination process. Autodesk\u2019s Revit explicitly lists interference check among Revit\u2019s collaboration features, so Revit clash detection is a valid part of the workflow. The limitation is that broader BIM coordination usually needs federated review, issue ownership, and cross-discipline visibility that sit beyond one authoring model.<\/p>\n<\/div><\/div><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"References\"><\/span>References<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Autodesk.
