The Change Order Is Where Your Margin Goes to Die

Ask a general contractor about the job that got away and the base contract is rarely the villain. The estimate was fine. The crew was fine. What killed the margin was the pile of changes – the extra work that got done, the directives that came by phone, the scope that crept a foot at a time – none of it priced, documented, or signed until the job was over and the leverage was gone. The change order is where more construction margin dies than anywhere else, and it dies quietly.

Two ways a change order costs you money

Changes destroy margin in two distinct ways, and they need different fixes. The first is work you performed and never got paid for – the undocumented change. The second is work you did get paid for, but priced too low because you quoted it under pressure, in the field, without your real costs in front of you. The first is a discipline problem. The second is a pricing problem. Most contractors have both.

The unpriced change is a gift to the owner

Here is how it happens on almost every job. The owner or architect directs a change – often verbally, often urgently. Your superintendent, rightly, keeps the job moving, because stopping to paper it would cost a day. The work gets done. The paperwork waits. Then it waits some more. By the time anyone prices it, the job is closing, the owner has spent their budget, and a change that was obvious in the moment is now a he-said-she-said you will probably lose. You did the work. You financed the material and the labor. And you gave it away – not because you agreed to, but because you never wrote it down while everyone still remembered.

The leaks are predictable:

• •Verbal directives that never become written ones.
• •Time-and-material work that is not tracked daily, so the ticket can never be reconstructed.
• •Scope creep – a series of additions, each too small to paper, that add up to real money.
• •Pricing that lags the work by weeks, so it is negotiated after the leverage is gone.

An unpriced change is not a change order. It is a donation – and the owner never asked you to be that generous.

Change-order discipline, not a better attitude

You do not fix this by telling the field to try harder. You fix it with a process that makes the right thing the fast thing:

• •Log every directive the day it is given – who, what, when – even before it is priced. The contemporaneous record is what wins the argument later.
• •Price before you proceed whenever the schedule allows, with your real costs, not a field guess.
• •When you cannot price first, track the change as time-and-material daily, with signed tickets, so the number is defensible.
• •Tie every change order to the budget and the schedule, so its effect on both is visible – not discovered at closeout.

None of this is exotic. It is structure, applied consistently, at the moment the change happens rather than the month the job closes.

That is where the right system earns its keep. In SCPM Project, a change is logged against the job budget and the WIP the moment it is raised, priced or not, so an unpriced change is a visible open item instead of a quiet loss. Structure defeats chaos – and the change order is where chaos does its best work.
