Building materials suppliers cover lumber yards, drywall and insulation suppliers, roofing suppliers, ready-mix concrete plants, tile and stone yards, flooring and carpet suppliers, paint stores, glass shops, molding suppliers, kitchen cabinet and countertop suppliers, and sheet metal suppliers. These are procurement relationships, and for a general contractor or builder they work best when set up before the first order, not at the counter. Most yards offer contractor accounts with net terms and trade pricing; opening one usually takes a credit application and references, so start the process during preconstruction rather than the week framing begins. Once the account exists, the practical questions are lead time and logistics. Commodity lumber and drywall are typically stocked and can deliver in days; engineered lumber, custom windows in glass packages, cabinet lines, and slab countertops are order-driven and can run weeks, so sequence those purchase orders off the construction schedule with float. Ready-mix concrete is its own discipline: pours are scheduled against plant capacity, mix designs may need submittal approval, and a missed pour window ripples through the whole slab and foundation sequence. Decide early which materials go will-call versus jobsite delivery. Will-call suits small fill-in runs; jobsite delivery matters for framing packages, drywall stocking (many suppliers will place board room-by-room), and roofing loads that go straight to the roof by boom truck. Confirm whether the delivery comes with a forklift, boom, or Moffett, and whether the site can actually receive it. On commercial and public work, expect submittal requirements: product data for insulation R-values, roofing assembly approvals, tile and stone samples. California projects also involve Title 24 energy compliance, which shapes insulation and glazing selections, so make sure the supplier can document what the energy consultant specified. A supplier who delivers accurately and on the promised day is worth as much to the schedule as a good sub.
Most yards run a credit application with business and trade references, and decisions typically come back within days, so start during preconstruction, not the week framing begins. Once the account is open, agree pricing on the commodity items the project will burn through and walk the takeoff with the yard's estimator so the framing package ships in the sequence the framer will use it. Confirm engineered lumber lead times separately; they run longer than stock dimensional lumber.
It varies by line, but cabinets are usually one of the longest-lead finish items. Imported and semi-custom lines can run many weeks from approved drawings, and countertop fabrication cannot start until cabinets are set and the tops are templated. Order cabinets early enough that they arrive before drywall and paint are done, and build the template-to-install gap for countertops into the finish schedule.
Will-call works for small quantities, fill-in runs, and materials a crew can carry in a pickup: paint, fasteners, a few sheets of drywall. Jobsite delivery pays off on framing packages, drywall stocking, roofing loads placed by boom truck, and anything palletized. Confirm the delivery equipment and site access in advance; a boom truck that cannot reach the roof or a flatbed that cannot enter the site turns a delivery into a labor problem.

The mix design against the structural drawings, whether the engineer or inspector needs to approve it beforehand, plant-to-site travel time, truck spacing for the pour rate the crew can handle, and washout arrangements on site. On inspected work, coordinate the pour date with the deputy inspector or testing lab so cylinders can be cast.
Contractors typically run primary packages through a yard: framing, structural work, and anything that needs multiple coordinated deliveries. Grade consistency, takeoff service, delivery scheduling, and account terms matter more there than shelf price. Big-box stores are the right call for small, urgent fill-in runs a crew can grab the same day. The deciding factor most pros cite is reliability: a yard that delivers the right material on the promised day protects the schedule.
