SmartOverlay for Subcontractors

Every undetected drawing change is money you’re leaving on the table.

SmartOverlay shows you every change between drawings in seconds. No more guessing, no more missed variations.

The Problem

What missed drawing changes cost subcontractors

Uncompensated scope changes
You build the change without claiming it. Your profit margin absorbs the cost. On a typical project, this can mean thousands in lost revenue per undetected variation.
Time-barred variation claims
Most construction contracts require variation notices within strict timeframes. If you don’t detect the change in time, you lose the right to claim—regardless of merit.
Procurement to the wrong revision
Materials ordered against the old drawing arrive wrong. Returns, re-orders, and storage fees compound the loss and push your programme out.
Manual comparison takes too long
You’re trusting a 10-minute manual scan to catch changes that affect your profit margin. On a drawing set of 14+ sheets, subtle changes are invisible to the naked eye.

In Practice

A day with SmartOverlay

Tuesday morning. Your team receives 14 revised architectural drawings for a commercial fit-out. Last time, you spent 3 hours manually comparing them and still missed two wall relocations that added $8,000 of scope you absorbed. This time, you run them through SmartOverlay. In 8 minutes, all 14 are compared. 23 changes are highlighted. Two of them are scope additions worth $12,000 in variation claims. You submit the variation notice the same day—well within the contractual notification period.
You’re not in the business of doing free work. Professionals check their drawings properly.

Ready-to-send message
“Every time a drawing revision comes through, we’re at risk of missing scope changes we should be claiming. I’ve been trialling SmartOverlay—it compares drawings and shows every change in seconds. On the last project, it identified three variations we would have missed. The subscription costs a fraction of a single variation claim. Can I set it up for the team?”
