Every commercial owner we talk to has a version of the same story. The project started well, the numbers looked reasonable, and then somewhere around month four the change orders started arriving and nobody could explain where the original estimate went.
That outcome is almost never a surprise in hindsight. The warning signs were there during the interview. They just were not the things people usually ask about.
Here are the five questions that tell you the most about a general contractor, and what a good answer actually sounds like.
1. Who is actually running my job, and what else are they running?
The people in the interview are frequently not the people on your site. Ask for the name of the project manager and the superintendent who will be assigned to your project, then ask how many other jobs each of them is carrying at the same time.
A good answer names real people, states their current workload honestly, and explains what happens if that workload changes mid-project.
A warning sign is a contractor who will not commit to names until after the contract is signed. If the staffing plan is flexible before you sign, it will be flexible after.
2. How do you build an estimate, and what is not in it?
Every estimate has exclusions. The question is whether your contractor volunteers them or buries them.
Ask specifically about the things that most often blow up a commercial budget: site conditions and utilities, long-lead equipment, permit and impact fees, owner-furnished items, and allowances that were set before anyone made a selection.
A good answer walks you through the exclusion list without being asked twice, and flags which allowances are most likely to move.
A warning sign is an estimate that is noticeably lower than the others and cannot explain why. Low numbers do not stay low. They just get corrected later, in change orders, when you no longer have anyone to compare them against.
3. What does your change order process look like in practice?
Change orders are not inherently a problem. Owners change their minds, conditions get discovered, and codes get interpreted. What matters is whether you find out about the cost before the work happens or after.
A good answer describes a written process with pricing submitted and approved before the work proceeds, and a running log you can see at any time.
A warning sign is any version of “we handle that at the end.”
4. How do you select and qualify subcontractors?
On a commercial project, the general contractor performs a fraction of the work. Most of what gets built is built by subcontractors. Their quality is your quality, and their financial stability is your schedule risk.
A good answer covers prequalification, how long the contractor has worked with the trades on your project type, and what happens if a sub fails to perform.
A warning sign is a contractor who bids out every trade to the lowest number every time. The savings on paper tend to reappear as delays and rework.
5. Can I talk to an owner whose project went badly?
Anyone can produce three happy references. The more useful question is what happened on a project that went sideways, because every builder with real volume has one.
A good answer is a specific story: what went wrong, what it cost, what the contractor did about it, and whether the owner would hire them again. Willingness to have that conversation says more about a builder than a portfolio does.
A warning sign is a contractor who claims nothing has ever gone wrong.
The point of asking
None of these questions require construction expertise to ask, and none of them can be answered well by a contractor who has not thought hard about how they run work. That is exactly why they are useful.
The best time to find out how a builder handles pressure is before there is any. Ask early, listen for specifics, and pay attention to what gets volunteered without prompting.
If you would like to run these questions past us on a project you are considering, we are glad to have that conversation. No pitch required.
