A trade subagreement, more commonly called a subcontract, is the executed contract between a general contractor and a subcontractor defining the subcontractor’s specific scope, price, schedule, and contractual obligations for their portion of the project. It’s the formal document that comes out of the buyout process once negotiations between GC and sub conclude.
It incorporate the prime contract by reference through flow-down language, binding the sub to relevant terms established at the prime contract level, such as insurance requirements, dispute resolution procedures, and certain payment terms, even though the sub never directly signed that prime contract itself. This layered structure is standard industry practice, but it means a careful sub, or their counsel, should understand which prime contract terms actually flow down rather than assuming the subagreement’s own text tells the complete story.
Scope definition within a trade subagreement deserves particular attention, since it’s typically the section most directly responsible for later disputes if it’s vague or inconsistent with the actual proposal that was negotiated. An agreement that doesn’t precisely match what was discussed and agreed during negotiation — different inclusions, different exclusions, even unintentionally — becomes the governing document regardless, which is exactly why reviewing the final executed text against the negotiated deal, line by line, matters more than it might seem given how routine that final signing step can feel after a long negotiation.
Because so much of a project’s actual construction risk gets transferred through this document, GCs increasingly maintain standardized subagreement templates with negotiated modification points, rather than drafting each subagreement from scratch, which speeds buyout while still preserving room to address genuinely project-specific terms where needed.
A detail worth double-checking before execution: confirming the subagreement’s payment terms actually match the negotiated deal, not just the scope and price. Payment timing, retention percentage, and conditions for release can all differ meaningfully from a firm’s standard template language, and a sub who doesn’t carefully check this section specifically can end up bound to less favourable payment terms than what was actually discussed and agreed during negotiation.
Termination and default provisions within a trade subagreement deserve careful attention from both parties, since these clauses define what happens in the worst-case scenario where the relationship breaks down entirely. A sub who’s never actually read their own termination clause carefully may be surprised by how quickly a GC can terminate for convenience or default under the specific language they originally signed. A brief legal review of these specific provisions, even for a firm’s own standard template, is worth the modest cost relative to the risk of an unpleasant surprise later.
