The Cost of A Late Caught Clash by Project Phase

The direct, visible cost associated with a late caught clash by project phase is usually smaller than the total real cost, once schedule impact, administrative overhead, and downstream effects on other trades or project phases are accounted for.

What the Visible Number Misses

Beyond the direct cost, there is typically schedule impact, since resolving an issue related to a late caught clash by project phase often means other work has to pause or be resequenced around it. There is also administrative overhead: documentation, communication between parties, and sometimes formal change order processing that adds real time and cost beyond the underlying work itself.

Why Timing Changes the Cost So Much

The same underlying issue costs dramatically different amounts depending on when it is caught. Caught during design, it usually means a redrawn detail or a coordination adjustment. Caught during construction, after related work has already progressed, it typically means demolition, rework, and schedule delay layered on top of the original fix.

Where This Connects to Design-Phase Review

Systematic, cross-discipline review during design is aimed directly at catching the issues that would otherwise surface later as this kind of cost. Structured AI's QA/QC Compliance Checks and Overlay feature are built to catch coordination and code compliance gaps before a drawing set leaves the office, which is exactly the point in a project where catching an issue is cheapest.

FAQ

Is there a standard industry figure for this cost? Estimates vary significantly by project type, region, and how the cost is measured, so a single universal figure is not reliable to cite without a specific, sourced study behind it.

Does better upstream review eliminate this cost entirely? No, but it meaningfully reduces the preventable share of it, the portion that traces back to coordination or documentation gaps that a more thorough design-phase review could plausibly have caught.

How should a firm start tracking this cost internally? Categorizing occurrences by root cause, rather than just counting total cost, reveals which specific gaps are driving the expense, which is more actionable than a single aggregate number.
