Owner's reps get a lot of uncomfortable phone calls. But one of the most common, and most avoidable, is the client calling about a change order they didn't see coming. It's an awkward conversation because by the time that call happens, the problem usually isn't new. Often times, it's been sitting in the project since before construction started.

Most clients assume change orders are a construction problem. Something the contractor did, or didn't do, or didn't account for. And sometimes that's true. But the majority of change orders that catch owners off guard aren't construction surprises. They're bid process failures that just took a few months to show up.

By the Time the Change Order Arrives, the Damage Is Already Done

Scope gaps are the most common culprit. A contractor submits a bid that's missing something: an allowance, a trade package, a specific requirement buried in the specs; and it doesn't get caught during the bid review. The owner selects that contractor, often because their number looked competitive, and the project moves forward. Then six weeks into construction, the contractor submits a change order for the work they never included, at a price the owner has no leverage to negotiate.

The frustrating part is that the gap was almost always visible in the bid if someone had the time and the tools to look for it. When one contractor's electrical number is $80,000 lower than everyone else's, that's not necessarily good news. It's a question that needs to get answered before anyone signs a contract. A thorough bid review asks those questions. A rushed or manual one often doesn't.

This Is Where Owner's Reps Add Real Value

Catching scope gaps before a contract is signed is one of the most valuable things an owner's rep can do for a client. It's the kind of proactive work that saves real money and builds real trust. But it requires a bid review process that's actually set up to surface those discrepancies.

When bids come in on a standardized format, variances are visible immediately. When they come in as three different spreadsheets and a PDF, someone has to manually reconcile everything before they can even start looking for problems. The real problems lie in the fact that it's normally one or the other. The GC's eithe bid on the owner's rep bid form or provide their own bid. The first misses critical information like what is actually included or excluded and second takes time most teams don't have to review. This is why things get missed, and missed things become change orders.

The Conversation You Want to Have With Clients

The best owner's reps don't wait for a change order to explain the bid process to their clients. They set expectations upfront about how bids will be collected, how they'll be reviewed, and what the team is specifically looking for before a contractor gets selected. That conversation does two things: it demonstrates your expertise before the project even starts, and it gives you a clear framework to point back to if something does come up later.

Clients who understand the process trust the outcome. And clients who trust the outcome tend to come back to you with the next project.

If your clients are consistently getting hit with surprises mid-construction, it's worth looking at what the bid review process looked like before they broke ground. The answer to most of those surprises is usually in there somewhere.
