For an estimator, the number does not stop being at risk when the bid is accepted. Between award and the first day on site, a scope that is not reconfirmed can drift, and the number you priced becomes a negotiation in the field.
A bid is accepted on a set of assumptions. Between award and the start, drawings get revised, adjacent trades get defined, and the field takes shape. Each change is a chance for the scope the estimator priced to diverge from the scope that gets built.
The estimator rarely sees the drift happen. It shows up later as a change order argued after the fact, or a margin spent covering a gap no one confirmed.
Reading the priced scope against the current drawings before the crew starts catches the items that moved: a detail that changed, a responsibility line that shifted to or from an adjacent trade, an assumption that no longer holds.
Each one is cheap to settle before the start and expensive to settle at install. The point is to lock the built scope to the priced scope while both can still be adjusted on paper.
A finish scope confirmed before the start protects the estimator's number directly. What the crew installs matches what was priced, so the final invoice reads as the bid plus documented changes, not a set of surprises to defend.
That is the difference between a number that holds from award to closeout and one that has to be reconstructed at billing.
Before the crew starts, D'Matos reads the finish scope against the current drawings and confirms it in writing, flagging anything that moved since the bid. The estimator gets a scope that still matches the number, or a clear list of what changed.
The result is a smaller gap between what you priced and what gets built, which is the only version of the estimate that reaches closeout intact.
Send us the scope and we review it. No commitment required.
