General Contractor (GC)
The firm that holds the prime contract and is responsible for delivering the finished project.
Quick Answer
A general contractor (GC) is the firm that holds the primary contract with the owner and is responsible for delivering a construction project. GCs manage the schedule, budget, and site, and they hire and coordinate subcontractors for most of the actual trade work. Their responsibility spans from preconstruction planning through final completion.
The Full Picture
The general contractor role exists because construction requires dozens of specialized trades — concrete, steel, electrical, mechanical, glazing — and someone has to be accountable to the owner for the whole thing coming together on budget, on schedule, and to spec. Rather than the owner contracting separately with every trade, the GC holds that single point of accountability.
Mechanically, the GC's own staff typically performs some self-perform work — often concrete, carpentry, or general conditions labor — but the bulk of construction is executed by subcontractors the GC solicits, bids, buys out, and supervises. The GC manages the overall schedule, site logistics, safety, quality control, and the flow of money and information between the owner, the design team, and every subcontractor on site.
In practice, the GC's involvement often starts well before construction: on a negotiated project the GC is engaged during design to run preconstruction — estimating, constructability review, and bid solicitation — before construction ever begins. On a hard-bid job the GC compresses that same work into the bid period, then executes it once awarded the contract.
For preconstruction specifically, the GC's team is the one turning drawings and specs into a priced, buildable plan: reviewing documents for gaps, taking off quantities, soliciting and leveling subcontractor bids, and assembling the number the owner ultimately signs off on — whether that's a lump sum or a GMP.
Real Examples
Common Misconceptions
People assume: A general contractor builds most of the project with its own workers.
Actually: On most commercial projects, the GC self-performs only a fraction of the work — often general conditions labor and select trades — while subcontractors execute the majority of construction under the GC's coordination.
People assume: A GC's job starts once construction begins.
Actually: On negotiated projects especially, the GC is often engaged during design to run preconstruction: estimating, constructability review, and bid solicitation happen well before the first shovel of dirt moves.
Does MeltPlan Solve This?
Partially — adjacentMeltPlan doesn't define or replace the GC's contractual role — that's a legal relationship with the owner. But it's built specifically for GC preconstruction teams: the document review, quantity takeoff, bid package creation, and bid leveling work a GC's precon staff does before breaking ground is exactly what MeltPlan's products cover.

What's the difference between a general contractor and a subcontractor?
The GC holds the prime contract with the owner and is responsible for the whole project. Subcontractors are hired by the GC to perform specific trade work — electrical, plumbing, drywall — under a separate contract with the GC, not with the owner.
What does a general contractor do during preconstruction?
The GC's precon team reviews drawings and specs, produces quantity takeoffs, solicits and levels subcontractor bids, flags constructability issues, and builds the schedule — turning a design into a priced, buildable plan before construction starts.
Does a general contractor do any of the physical work?
Often some. Many GCs self-perform certain scopes — commonly concrete, carpentry, or general conditions labor — with their own crews, while subcontracting the majority of specialized trade work.
What's the difference between a GC and a construction manager?
The terms overlap heavily and are often used interchangeably. "Construction manager" sometimes implies an agency-CM role advising the owner without holding trade contracts, while "general contractor" implies holding the prime contract and the subcontracts — though in CM at Risk delivery, the CM functions much like a GC.
Who does a general contractor report to?
The owner, through the prime contract, with the design team (architect and engineers) as a close collaborator on design intent, quality, and contract compliance throughout the project.
