Accessibility from the Model"},"content":{"rendered":"<p><strong>Yes: a BIM model can detect accessibility barriers before they are built, as long as accessibility criteria are incorporated into the model.<\/strong> The same logic that detects a pipe crossing a beam can reveal a column narrowing a corridor, a door swinging into the maneuvering space or a ramp with the wrong slope. Fixing it in the model costs far less than demolishing on site.<\/p>\n<p>This content is part of our <a title=\"construction magazine for the Americas\" href=\"https:\/\/constructhubs.com\/en\/digital-magazine\/\">construction magazine for the Americas<\/a>, within the editorial line dedicated to <a title=\"architecture and design\" href=\"https:\/\/constructhubs.com\/en\/category\/architecture-and-design\/\">architecture and design<\/a>.<\/p>\n<p>The proposal comes from <strong>Grupo ADIPSA<\/strong>, a Panamanian structural design and BIM coordination firm, which suggests broadening interdisciplinary coordination so that not only systems work, but also people in the space.<\/p>\n<p>You can also read the <a title=\"version published in the August 2026 issue of ConstructHUBS magazine\" href=\"https:\/\/cp.aflip.in\/constructhubs-ago26.html#page\/14\" target=\"_blank\" rel=\"noopener\">version published in the August 2026 issue of ConstructHUBS magazine<\/a> (in Spanish).<\/p>\n<h2>A barrier can also be a clash<\/h2>\n<p>In BIM coordination, a clash occurs when two elements conflict. From an accessibility standpoint there are conflicts too:<\/p>\n<ul>\n<li>A column that reduces a circulation space.<\/li>\n<li>A door whose swing invades the area needed to maneuver a wheelchair.<\/li>\n<li>An installation that alters a planned route.<\/li>\n<\/ul>\n<p>The difference lies in broadening the view: coordinating so that people can use the space properly.<\/p>\n<h2>What can be checked in a BIM model?<\/h2>\n<ul>\n<li>Door and corridor widths.<\/li>\n<li>Maneuvering spaces.<\/li>\n<li>Routes and accessible paths.<\/li>\n<li>Ramp slopes and configuration.<\/li>\n<li>Location of obstacles.<\/li>\n<li>Access to elevators.<\/li>\n<li>Restroom layout.<\/li>\n<li>Clashes between installations and circulation areas.<\/li>\n<\/ul>\n<h2>What BIM does not replace<\/h2>\n<p>BIM does not replace regulations or the professional who evaluates the project. Technology only checks what has previously been defined as a requirement. That is why accessibility criteria \u2014such as the <a title=\"universal accessibility and DALCO criteria\" href=\"https:\/\/constructhubs.com\/en\/universal-accessibility-dalco-criteria\/\">DALCO criteria for universal accessibility<\/a>\u2014 must be defined from the start and built into the model.<\/p>\n<h2>Fix it in the model, not on site<\/h2>\n<p>Detecting a barrier in a finished building means demolition, modifications, costs and delays. One of the great advantages of digital construction is making decisions while they are still easy to change. As ADIPSA puts it: \u201cthe best architectural barrier is the one that never gets built.\u201d<\/p>\n<p>This approach relies on the same <a title=\"BIM clash detection\" href=\"https:\/\/constructhubs.com\/en\/bim-clash-detection\/\">BIM clash detection<\/a> process used to prevent conflicts between structure and installations.<\/p>\n<h2>Frequently asked questions<\/h2>\n<h3>Does BIM automatically check accessibility codes?<\/h3>\n<p>Not on its own.
