What is EPC (Engineering, Procurement & Construction)?
A delivery model in which a single prime contractor handles engineering, procurement, and construction for a project. The EPC award — when the owner selects the prime — is the milestone at which subcontract opportunities for specialty trades become imminent, typically 2–6 weeks later.
In BD conversations, “EPC” does double duty: it names the delivery model and, loosely, the prime contractor itself (“who's the EPC on this job?”). For specialty trades, the EPC award is the single most actionable milestone in a project's life — it converts an owner-side opportunity into a contractor-side one, with a named counterparty whose procurement team will buy out trade packages on a schedule.
Example: an owner announces a gas-fired plant and, months later, signs an EPC contract with a national prime. Within weeks the prime's procurement group issues subcontract RFQs for civil, mechanical, and electrical scopes. A sub that opened a relationship with that prime's regional office before the award gets a bid invitation; one that waits for the public announcement often finds the bid list already set.
The practical rule: track projects toward their EPC award, and treat the award itself as a starting gun, not news. The two-to-six-week window between prime award and sub-RFP is where prepared BD teams win.
