If you learn only three things before your first day in the trailer, learn these. RFIs, submittals, and buyout are the connective tissue of a construction project — get fluent in them and you can hold a real conversation with any superintendent or subcontractor.
RFIs — asking the right question, on the record
A Request for Information is how the field asks the design team to resolve something the drawings don't answer: a conflict, a missing detail, an ambiguity. The skill isn't filling out the form — it's spotting the issue early and writing it so the answer actually unblocks the work. A good RFI protects the schedule; a vague one invites a useless answer.
Submittals — proving what gets installed
Before a sub fabricates or orders, they submit product data, shop drawings, or samples for the architect to review against the specs. Miss a submittal and the fabricator misses their slot, and now your steel or your elevator is late. Managing the submittal log — knowing what's out, what's due, and what's holding up procurement — is quietly one of the highest-leverage things a PM does.
Buyout — turning a budget into contracts
Buyout is where you take the estimate and actually award the work: soliciting, leveling, and executing subcontracts and purchase orders for every trade. The trap is the apparent low bid that has a scope gap — the number looks great until you realize connections or restripe work weren't included. Leveling bids so you're comparing the same scope is the whole game.
Why they go together
These three feed each other. Buyout sets who's doing the work; submittals prove what they'll install; RFIs resolve what the documents left open. A PM who runs all three cleanly keeps procurement ahead of the schedule instead of chasing it. That's the difference between a job that flows and one that lurches.
