General contractor vs construction manager: what is the difference

"General contractor" and "construction manager" get used almost interchangeably in casual conversation, and that is a problem, because the two roles carry a different contract structure, a different risk position, and a different answer to the question of who is actually accountable when something goes wrong.

What a general contractor does

A general contractor typically holds the contracts directly with the trades, whether those trades are the contractor's own crews or subcontractors it has hired. The general contractor is accountable for delivering the finished project for an agreed price, and that price generally includes the risk of most of what happens during construction. If a subcontractor's cost runs over, that is largely the general contractor's problem to absorb or manage, not the owner's.

What a construction manager does

A construction manager provides that same oversight of schedule, cost and quality, but usually on the owner's behalf rather than as the party holding every trade contract. Depending on the arrangement, the trades might be contracted directly to the owner with the construction manager coordinating them, or the construction manager might hold some contracts while advising on others. Either way, the construction manager's job is managing the project for the owner's interest, not carrying the same fixed-price risk a general contractor typically carries.

Where the risk actually sits

This is the real difference, more than the day-to-day work, which often looks similar from the outside. A general contractor on a fixed-price contract is generally on the hook if the job costs more than agreed, outside of legitimate change orders. A construction manager is typically paid a fee for managing the project well, with the cost risk of the trades sitting more directly with the owner. Neither structure is better in the abstract. They simply put the financial risk in different places, and an owner should know which one they are agreeing to before signing anything.

Where each one fits

A general contractor arrangement tends to fit an owner who wants one number, one contract, and one party accountable for hitting it, and who is comfortable letting that contractor manage the trade relationships without the owner's direct involvement in each one. A construction manager arrangement tends to fit an owner who wants more visibility and control over the trade contracts themselves, perhaps because some trades are already selected, or because the owner has the internal capacity to be more involved at that level of decision-making and wants the transparency that comes with it.

Questions worth asking either way

Whichever structure you are looking at, ask the same handful of questions. Who actually holds the contracts with the trades doing the work. How is a change in scope or cost documented and approved. Who is accountable if a subcontractor falls behind or does substandard work. And what happens to unused contingency at the end of the job, since that answer tells you a lot about how the fee or the risk was actually structured underneath the label.

The label matters less than the contract

Two companies can call themselves a general contractor and structure their risk almost like a construction manager, or the reverse. The label on a proposal is a starting point for the conversation, not the answer. Read the actual contract for who carries the cost risk, who holds the trade agreements, and how a dispute over cost or schedule gets resolved, because that is where the real difference between the two roles lives.

We take on both roles, general contracting with our own crews carrying the fixed-price risk, and construction management on behalf of an owner who wants that oversight with a different risk structure. We are licensed and insured, with over 20 years of combined experience running both kinds of projects across the greater Houston area. If you are trying to decide which structure actually fits your project, we are glad to walk through what each one would look like for your scope.
