Lumber from coniferous trees like pine and fir, used for framing and structural applications.
Softwood is lumber derived from coniferous (cone-bearing) trees such as pine, fir, spruce, and cedar. It is the primary material used for structural framing, sheathing, and rough carpentry in North American construction. Despite the name, some softwoods are harder than some hardwoods; the classification refers to tree type rather than actual hardness.
Softwood framing lumber is one of the most volatile line items in a bid because commodity prices swing sharply between estimate and award. Estimators must lock supplier quotes, account for escalation on long-lead projects, and confirm grade and species call-outs match the structural drawings, since substituting a lower grade to cut cost can fail inspection and trigger rework.
When pricing a wood-framed apartment building, the estimator pulls a board-foot takeoff for the studs, plates, and roof sheathing, then gets a 30-day-firm softwood quote from the lumber yard to protect the bid against a mid-month price spike.
