SmartOverlay for Quantity Surveyors

You’re assessing variation claims against drawing revisions. How long does the manual comparison take?

SmartOverlay shows exactly what changed between any two drawing revisions—so your cost assessments are based on verified scope changes, not assumptions.

The Problem

What missed drawing changes cost quantity surveyors

Time-consuming manual comparison
Overlaying drawings manually takes 30–60 minutes per pair. When multiple revisions are involved, the comparison alone can take days.
Assessments based on assumed scope
Without verified visual evidence of what changed, your cost assessments rely on what the claimant says changed. Overstated claims pass through. Legitimate changes get missed.
Disputed variations drag on
When neither party can show exactly what changed between revisions, variation disputes become arguments about interpretation rather than facts.
The Solution

Variation disputes based on interpretation

In Practice

A day with SmartOverlay

A subcontractor submits a variation claim referencing three drawing revisions. Before SmartOverlay, you’d spend a day overlaying the drawings manually. Now you run each pair through SmartOverlay. In minutes, you see exactly what changed—the claim is accurate on two items and overstated on the third. Your assessment is precise and defensible.
Accurate cost assessment depends on verified scope. SmartOverlay gives you the evidence.
