Project teams relying on trade-by-trade coordination reviews, without systematic clash detection, often discover intersecting MEP and structural elements only once construction has physically reached that specific point in the building.
Why Trade-by-Trade Review Misses Cross-Discipline Conflicts
Coordination review conducted trade by trade — each discipline reviewing its own drawings for internal consistency — is not structurally capable of identifying conflicts between disciplines, because no single trade’s review process is designed to check its own elements against every other trade’s geometry simultaneously.
Where the Gap Becomes a Physical Problem
Without a coordinated model that overlays every discipline’s geometry together, conflicts between, for example, a structural beam and a mechanical duct route remain invisible until construction physically reaches that location and the conflict becomes an immediate, on-site problem requiring real-time resolution.
Why On-Site Discovery Is the Most Expensive Point to Find a Clash
A clash identified in a coordination model before construction begins costs a design adjustment. The same clash discovered on-site, after concrete has been poured or structural steel erected around the conflict, costs demolition, rework, and schedule delay that a pre-construction check would have avoided entirely.
Identifying Conflicts Before They Reach the Site
After identifying why clashes routinely survive trade-by-trade review into construction, the fix is systematic clash detection performed against a coordinated model before construction begins, rather than relying on trade-by-trade review to somehow catch cross-discipline conflicts it was never designed to detect. DASH’s Navisworks clash detection is the pre-construction layer that identifies these intersections in the coordination model before they reach the site.
