Buyout is the process a general contractor runs after winning a project, negotiating and finalizing subcontracts with each trade partner so the awarded scope, price, and schedule actually lock down. A buyout contract, then, is the executed subcontract agreement that comes out the other end of that negotiation.
There’s a gap most people outside construction don’t realize exists between what a GC bids to the owner and what they actually pay subcontractors, and buyout is where that gap gets managed. The GC’s estimate for electrical might be $2.1 million based on a preliminary budget number, but buyout could land the actual subcontract at $1.95 million after competitive bidding among three or four qualified electrical subs. That difference, often called buyout savings, is real money, and tracking it project by project is standard practice on the GC’s side.
Scope gaps are the recurring headache in this phase. Every subcontractor’s proposal comes with a list of inclusions and exclusions, and if two adjacent trades both exclude the same piece of work say, both the drywall sub and the framing sub exclude furring at an exterior wall condition- that gap doesn’t show up until someone’s standing in the field wondering who’s supposed to install it. Careful buyout means cross-referencing every proposal against every other proposal in the same trade cluster before signing anything, not just checking each one against the drawings in isolation.
Timing matters too: buyout typically needs to close well ahead of mobilization, since long-lead items (switchgear, curtain wall, elevators) can carry procurement lead times of six months or more, and a delayed buyout on those trades can push the whole schedule regardless of how fast field work moves once it starts.
Buyout also carries a documentation obligation that’s easy to underweight in the rush to finalize pricing. The executed subcontract needs to actually match what was negotiated: the same scope inclusions and exclusions discussed verbally, the same unit prices, the same schedule milestones, and a mismatch between the negotiated deal and the signed document, even an unintentional one from a rushed contract drafting process, becomes the version that governs if a dispute ever arises later.
A GC’s own internal buyout log is worth thinking of as a living risk register, not just a pricing tracker flagging every trade still unsigned, every long-lead item still unordered, and every proposal with exclusions that haven’t yet been reconciled against neighboring trades gives project leadership a clear, current view of where real exposure still sits heading into mobilization.
