Why a change order costs what it does on a commercial job

A change order for a single relocated door came across a desk last spring, and it was not the door that cost money. It was the header already framed, the electrical rough-in already inspected on the other side of the wall, the drywall already hung, and the two days of resequencing for the crews who were supposed to be painting that corridor. The door was a few hundred dollars. The timing was the rest. If you want to read a change order the way a builder does, start with the calendar.

The calendar sets the price

The same design change priced during pre-construction is a line in the estimate. Priced after material is ordered, it carries a restocking charge. Priced after the work is in place, it carries demolition, disposal, rework and the cost of whoever was scheduled to be in that room next. This is the largest single reason two owners can ask for identical changes and see numbers that differ by a multiple. It is also why we push decisions early and say so plainly: a finish selection made in week two is cheap and one made in week twenty is not, no matter who is building it.

Who asked for the change

An owner-driven change, a program shift or a preference for a different fixture, usually comes with lead time. There is room to price alternatives, shop the material and fit the work into the schedule where it hurts least. A field condition is different. The wall opens and the pipe is not where the drawings show it, or the slab under the old tile is two inches out of level. That gets priced under pressure, fast, because the crews are standing there, and the pressure limits how much shopping goes into it. On renovation and PIP work, where the existing building is the biggest unknown, we walk the space with the owner before pricing and open what we can, so more of the surprises move into the estimate and out of the change order log.

How many trades it touches, and what it does to the date

Swapping one finish material is a one-trade change. Moving a wall is framing, electrical, mechanical, fire protection, drywall, paint and flooring, plus the coordination among all of them. The coordination is real cost, not padding. Because our framing, drywall, tile, millwork and paint crews are in-house, the resequencing on a multi-trade change is a conversation on site rather than a round of subcontractor quotes, which shortens the pricing and often lowers it. The other multiplier is the finish date. A change that pushes the opening carries extended general conditions, and on a hotel or a retail lease it carries the owner's lost revenue on top. Any change order review should ask what happens to the date before it asks about the price.

What a good change order looks like on paper

It states the reason for the change and who initiated it. It itemizes labor, material, equipment and subcontract cost, and it shows the markup as its own line rather than folding it into the totals. Markup for overhead and profit is a normal part of the number and not the thing to argue about; the thing to check is whether the direct costs underneath it match the actual scope. It states the schedule effect in days, even if the answer is zero. And it is signed before the work starts, not reconstructed after. An owner who receives change orders in that form can tell a fair price from a padded one in a few minutes, and can decide with the full picture instead of a lump sum.

We price every change this way because the principal who signs it is the same person standing on your site when the wall comes open. If you have a project in design, or one already under way with a change log you would like a second look at, send over the plans and we will walk through what is driving the numbers.
