Change Orders: How to Cut Them Before They Happen

6 min read

By the time a change order reaches your desk it is a negotiation. The work that prevents it happened months earlier.

Where change orders actually come from

In practice, nearly all of them trace to one of five sources:

Incomplete or uncoordinated documents. Gaps between disciplines become field questions, and field questions become cost.
Unforeseen conditions. Real, but frequently a diligence failure — undocumented utilities, unexpected soils, hidden structure in a renovation.
Owner-directed change. Decisions made late, or reversed after they were made.
Scope gaps between trades. Nobody bought the item because every bidder assumed someone else had it.
Schedule and escalation. Delay drives extended general conditions and price movement on unbought materials.

Only the second category is genuinely unpredictable, and even that shrinks with better preconstruction.

Prevention before the contract

Run a constructability review with the builder before the documents are final, and require written responses.
Produce a scope gap matrix across trades before buyout. Every division of work gets an owner.
Hold a real bid leveling session and resolve every exclusion in writing before award.
Close all open allowances you can before signing, and define reconciliation for the ones you cannot.
Freeze finishes and equipment selections before the drawings go out — late selection is a leading cause of owner change.
Buy out long lead items early to lock price and delivery.

Governance during construction

Require written notice within a defined period, with the contract clause cited. No notice, no claim.
Require full backup: labor hours and rates, material invoices, equipment, and any schedule impact analysis.
Cap markups in the contract, and separate them for self-performed and subcontracted work.
Distinguish cost impact from time impact. Approving one is not approving the other.
Use a proposed change order log with status, dollar value, and days — reviewed weekly, not monthly.
Never authorize work to proceed on a verbal price.

Negotiating a specific change

Ask three questions in order. Is it actually extra work, or was it in the original scope? Is the pricing consistent with the contract unit rates and markups? Is the schedule impact real, or is it float consumption?

Most disputed change orders fail one of the first two tests. Owners who make that examination routine rather than confrontational get better pricing without damaging the relationship.

Track the pattern, not just the total

A change order log that only shows dollars is a receipt. Categorize each one by root cause and review the distribution monthly. If design gaps dominate, the design team needs attention. If owner-directed change dominates, your decision process is the problem. If unforeseen conditions dominate, diligence needs to improve on the next project.

The takeaway

Change orders are a downstream symptom. Complete documents, a scope gap matrix, early buyout, frozen selections, and a disciplined notice-and-backup process cut them dramatically — and turn the ones that remain into a manageable negotiation instead of a surprise.
