Its purpose:<\/p>\n<ul>\n<li>Develop precise geometry.<\/li>\n<li>Incorporate technical information: materials, specifications and properties.<\/li>\n<li>Meet the agreed level of development (LOD 200, 300, 350 or 400).<\/li>\n<li>Produce consistent, traceable documentation.<\/li>\n<\/ul>\n<p>In structures, for example, it defines actual sections, reinforcement, connections, precast elements and fabrication tolerances. But discipline modeling does not guarantee that systems from different trades are compatible with each other.<\/p>\n<h2>What is BIM coordination?<\/h2>\n<p>It is the process that brings all disciplines&#8217; models into a common environment and analyzes them as a system. The goal is no longer to represent, but to validate. It includes:<\/p>\n<ul>\n<li>Clash detection.<\/li>\n<li>Clearance and technical accessibility analysis.<\/li>\n<li>Review of maintenance spaces.<\/li>\n<li>Constructability and erection sequence assessment.<\/li>\n<\/ul>\n<h2>BIM modeling vs. BIM coordination<\/h2>\n<table>\n<thead>\n<tr>\n<th>Criterion<\/th>\n<th>BIM modeling<\/th>\n<th>BIM coordination<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Scope<\/td>\n<td>Technical development by discipline<\/td>\n<td>Cross-review and comprehensive validation<\/td>\n<\/tr>\n<tr>\n<td>Responsibility<\/td>\n<td>Internal accuracy of the model<\/td>\n<td>Overall project viability<\/td>\n<\/tr>\n<tr>\n<td>Cost impact<\/td>\n<td>Reduces documentation ambiguity<\/td>\n<td>Reduces rework, claims and overruns<\/td>\n<\/tr>\n<tr>\n<td>Risk mitigated<\/td>\n<td>Geometric errors<\/td>\n<td>Critical clashes and construction conflicts<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>What happens without formal coordination?<\/h2>\n<ul>\n<li>Models are not validated against each other.<\/li>\n<li>Structural clashes are detected late, on site.<\/li>\n<li>The integrity of the original design is compromised.<\/li>\n<li>The contractor absorbs unplanned adjustments.<\/li>\n<\/ul>\n<p>In steel structures, precast elements and industrial systems, where tolerances are minimal, lack of coordination affects fabrication, erection and logistics.

It ranges from conceptual models (LOD 200) to models suitable for fabrication and erection (LOD 400).<\/p>\n<h3>If every discipline models well, is coordination still needed?<\/h3>\n<p>Yes. Each model can be correct within its discipline and still clash with another. Coordination is what validates the whole.<\/p>\n<h3>Who does BIM coordination?<\/h3>\n<p>A BIM coordinator, who integrates the models, manages clashes and safeguards the overall viability of the project.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Why a project that is well modeled in BIM can still fail on site if it is not coordinated.<\/p>\n","protected":false},"author":3,"featured_media":1878,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[523],"tags":[],"class_list":["post-1960","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-technology-and-innovation"],"_links":{"self":[{"href":"https:\/\/constructhubs.com\/en\/wp-json\/wp\/v2\/posts\/1960","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/constructhubs.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/constructhubs.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/constructhubs.com\/en\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/constructhubs.com\/en\/wp-json\/wp\/v2\/comments?post=1960"}],"version-history":[{"count":1,"href":"https:\/\/constructhubs.com\/en\/wp-json\/wp\/v2\/posts\/1960\/revisions"}],"predecessor-version":[{"id":1988,"href":"https:\/\/constructhubs.com\/en\/wp-json\/wp\/v2\/posts\/1960\/revisions\/1988"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/constructhubs.com\/en\/wp-json\/wp\/v2\/media\/1878"}],"wp:attachment":[{"href":"https:\/\/constructhubs.com\/en\/wp-json\/wp\/v2\/media?parent=1960"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/constructhubs.com\/en\/wp-json\/wp\/v2\/categories?post=1960"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/constructhubs.com\/en\/wp-json\/wp\/v2\/tags?post=1960"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
