SmartOverlay for Builders

One missed drawing change can mean weeks of rework and a variation claim you can’t recover.

SmartOverlay highlights every change between drawing revisions—so your site team builds the right scope the first time.

The Problem

What missed drawing changes cost builders

Rework from undetected changes
Your site team builds to the old revision. When the change is discovered, rework costs 3–5× the original scope. The programme impact ripples through every trade on site.
Subcontractor coordination failures
Undetected changes in one discipline cascade through services coordination. One missed duct relocation creates clashes with electrical, hydraulic, and ceiling trades.
Late variation notices to the client
You can’t submit what you don’t detect. Late variation notices erode client confidence and make claims harder to negotiate.
Drawing management overhead
With dozens of revised drawings per week across multiple packages, manually tracking what changed in each revision is a full-time job that nobody has time for.

In Practice

A day with SmartOverlay

A revised structural drawing arrives Friday afternoon—the engineer has relocated a footing by 400mm. Without SmartOverlay, your site foreman wouldn’t have noticed until concrete day on Monday. With SmartOverlay, you see the change instantly. You issue a variation to the client on Friday, redirect the subcontractor, and avoid $15,000 in rework costs. The programme stays on track.
Your reputation is built on delivering projects right the first time. SmartOverlay ensures your team always works from the right information.

Ready-to-send message
“We need a better way to track what’s changing in our drawing revisions. I’ve been trialling SmartOverlay—it compares any two drawings and highlights every difference in seconds. On the current project, it caught a footing relocation we would have missed until concrete day. It’s a fraction of the cost of one rework event. Worth setting up for the team?”
