A commercial general contractor builds your project and carries the risk of delivering it on time and on budget. A construction manager works for you, oversees the build, and does not profit from the construction itself. The GC signs the construction contract. The CM signs a professional services agreement. Most Central Texas projects only need one.
We offer both at Aday & Associates, which puts us in an unusual spot. We have no reason to steer you toward the more expensive arrangement, and we will say so when a project does not call for one. Here is the honest version of the comparison, including where each role stops earning its fee.
Commercial General Contractor vs. Construction Manager: The Short Answer
Question: What is the difference between a commercial general contractor and a construction manager?
Answer: A general contractor holds the construction contract, hires and pays the subcontractors, and is responsible for delivering the finished building. A construction manager is hired directly by the owner to plan, coordinate, and oversee the project as the owner’s advocate, without holding the trade contracts.
| Commercial General Contractor | Construction Manager | |
|---|---|---|
| Works for | You, under a construction contract | You, under a services agreement |
| Holds trade contracts | Yes | Usually no |
| How they are paid | Lump sum or cost plus fee on the build | Flat fee or percentage of project cost |
| Carries cost and schedule risk | Yes | Rarely |
| Hires subcontractors | Yes | Reviews and recommends |
| Best fit | Defined scope, single building, clear drawings | Phased work, multiple sites, no in-house project staff |
What a Commercial General Contractor Actually Owns
The GC owns the outcome. Once that contract is signed, the schedule, the subcontractor performance, the material procurement, and the punch list all sit on one company’s shoulders. If the framing crew shows up late, that is the GC’s problem to solve and, in most contract structures, the GC’s money at stake.
That single point of accountability is the entire argument for commercial general contracting. You have one phone number to call, one company answering for quality, and one warranty when the building is done.
Where the GC’s Money Comes From
This is the part owners rarely ask about, and it changes the whole comparison. A GC is paid to build. Under a lump sum contract, savings found during construction generally stay with the contractor. Under cost plus with a guaranteed maximum price, unspent contingency usually flows back to the owner or gets split.
Pro Tip: Ask any GC bidding your project which structure they are proposing and who keeps the savings. The answer tells you more about how the project will be run than any line item in the estimate.
Did You Know: A GC’s fee is only one slice of the price. Subcontractor markup, general conditions, and contingency often move the final number far more than the fee percentage owners tend to negotiate hardest.
What a Construction Manager Actually Owns
A construction manager owns the oversight, not the build. The CM plans, budgets, schedules, and supervises on the owner’s behalf. As the Construction Management Association of America defines the role, the CM represents the owner’s interest and provides oversight of the whole project directly for the owner.
On a project with several separate contracts, an in-house committee making decisions, or work phased around a business that has to stay open, that advocacy is worth real money. Our construction management services exist for exactly those situations.
Agency CM vs. CM-at-Risk in Texas
The two CM models are not close cousins. An agency CM advises and never holds construction risk. A CM-at-risk gives the owner a guaranteed maximum price and takes on cost risk, which makes it look a lot like a GC with a preconstruction seat at the table.
Texas public projects follow defined delivery methods for both models under Chapter 2269 of the Texas Government Code. Private commercial owners are not bound by that chapter, but the definitions are a useful yardstick when a firm’s proposal is vague about which model it is actually selling you.
We Sell Both. Here’s When We Tell Owners to Skip the CM.
We offer construction management and pre-construction consulting as standalone engagements, including for owners who already have a general contractor of record and want an independent eye on cost, schedule, and subcontractor performance. Selling both sides of this comparison means we have no reason to push you toward the pricier one.
So here is the honest version. A CM fee is hard to justify when three things are true at once: the scope is defined, the project is one building in one jurisdiction, and someone on the owner’s side can answer a question within a day. Add a construction manager to that project and you have layered a second fee onto a job that already has one accountable party.
The reverse is just as clear. A CM earns its fee on a medical or dental build phased around live patient hours, on a franchise or bank rollout crossing several municipalities with several permitting timelines, and on church or committee-led projects where nobody on the owner’s side does construction for a living. We have worked with a franchise client across four stores in four different municipalities over a five-year span. Work like that is a coordination problem before it is a construction problem.
Did You Know: Round Rock, Austin, Georgetown, Cedar Park, and Pflugerville each run their own permitting and inspection timelines. A project touching several of them is where owner-side oversight quietly pays for itself.
How to Decide Which One Your Project Needs
Start with three questions, in this order.
First, are the drawings finished? If a design is still moving, you need someone in the room during design, which is a preconstruction role before it is a CM or GC role. Our pre-construction consulting work often settles this question before an owner picks a delivery method at all.
Second, who makes decisions on your side, and how fast? A single owner who answers email in an hour rarely needs a paid representative. A board or committee usually does.
Third, how many contracts and jurisdictions are in play? One of each points to a GC. Several of either points to a CM.
Pro Tip: Ask any firm proposing construction management whether they also perform general contracting. A company that does both can explain the trade-off honestly instead of selling the only service it offers.
Which One Should You Hire?
The choice between a commercial general contractor and a construction manager comes down to accountability and complexity. A GC gives you one company carrying the risk of building your project. A CM gives you an advocate watching the people who do. Simple, well-defined builds usually need the first. Phased, multi-site, or committee-led projects usually need the second.
If you are not sure which one your build calls for, that is a fifteen-minute conversation, not a research project. Contact Aday & Associates for a free consultation, and we will tell you which delivery method fits your project, even when the answer is the less expensive one.
Frequently Asked Questions
Can the same company be both the general contractor and the construction manager?
Yes, and many Texas firms offer both. Some owners hire one company for both roles for simplicity, while others keep them separate so oversight stays independent from the build.
Is a construction manager more expensive than a general contractor?
A CM adds a fee on top of construction costs, so the total is usually higher on simple projects. On complex or phased builds, that fee is often offset by fewer change orders and shorter delays.
Does a construction manager hire the subcontractors?
Usually not. An agency construction manager reviews bids and recommends trade contractors, while the owner or general contractor holds the actual contracts. A CM-at-risk is the exception and does contract the trades.
Do I need a construction manager for a small commercial building?
Rarely. A single building with finished drawings, one permitting jurisdiction, and a responsive owner is typically well served by a general contractor alone.
What is a CM-at-risk in Texas construction?
CM-at-risk is a delivery method where the construction manager provides a guaranteed maximum price and carries cost risk, unlike an agency CM who only advises. Texas defines the model for public projects under Government Code Chapter 2269.
