Softwood

In Plain English

Lumber from coniferous trees like pine and fir, used for framing and structural applications.

Definition

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.

Why It Matters in Bidding

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.

Example

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.

Frequently Asked Questions

Softwood trades as a commodity tied to housing demand, mill capacity, tariffs, and freight, so quotes can move weekly. Estimators counter this by requesting firm-price periods, adding escalation contingency on long-duration jobs, and confirming the bid date against when the lumber will actually be purchased and delivered.
Quantify members by board feet or lineal feet per size, then convert to standard lengths and add waste, typically a percentage for cutting, blocking, and bracing. Separate studs, plates, headers, joists, and sheathing so each can be priced and ordered correctly, and tie grade and species to the structural notes.
Yes. Structural members are specified by grade and species combination, which dictates allowable spans and load capacity. Higher grades cost more per board foot, and substituting a cheaper grade can fail engineering review or inspection. Always price the exact grade shown on the drawings rather than assuming a generic stud grade.
