Timber / Lumber Order & Site Handling Verification Checklist

Essential Checklist+

Complete these critical checks before approving the work or proceeding to the next construction stage.

βœ“18 Inspection Points
βœ“5 Verification Categories
βœ“Species, Grade & Treatment Selection+
  • Structural grade confirmed against the design specification, not assumed from a generic name
  • Species (or species group) confirmed to match the design's allowable stress assumptions
  • Moisture content confirmed suitable for the application β€” kiln-dried (KD) for framing, appropriate rating for exterior use
  • Pressure treatment level confirmed to match the specific exposure category β€” ground contact, above-ground, or interior
  • Fastener and hardware material confirmed compatible with the treatment chemical used
βœ“Dimension & Quantity Verification+
  • Actual (dressed) dimensions used for volume, weight, and structural calculations β€” nominal size confirmed separately for board-foot billing
  • On-center spacing confirmed against the structural design or applicable building code, not a generic default
  • Wastage allowance matched to the actual job complexity, not a single default figure for every job
  • Calculated piece count cross-checked against the framing drawing or takeoff, not relied on alone
βœ“Site Storage & Handling+
  • Delivered lumber stored off the ground on stickers/dunnage, not stacked directly on soil or a wet slab
  • Stacked lumber covered or protected from direct rain and prolonged sun exposure while awaiting use
  • Pressure-treated lumber handled with the precautions on the treatment tag β€” gloves, dust control when cutting
βœ“Structural Use & Fastening Verification+
  • Actual span checked against the specific species/grade/size combination's published span table
  • Fastener type, size, and spacing schedule followed as specified, not substituted informally
  • Metal structural connectors (joist hangers, hurricane ties, post bases) installed exactly where specified
  • Minimum bearing length at each support confirmed adequate for the piece's size and load
  • Notches and drilled holes for services kept within the size and location limits allowed for the member
βœ“Waste, Reuse & Disposal+
  • Pressure-treated offcuts and sawdust disposed of per local regulation, never burned
Full QC Checklist+

Verification checklist for ordering and handling structural timber and lumber β€” covering species, grade, and treatment selection, dimension and quantity verification, site storage and handling, structural use and fastening, and waste and disposal. Use the Essential Checklist for critical checks before ordering and using lumber on site; expand to Full QC Checklist for complete quality control from order through installation.

βœ“Species, Grade & Treatment Selection+
  • Structural grade confirmed against the design specification, not assumed from a generic name
  • Species (or species group) confirmed to match the design's allowable stress assumptions
  • Moisture content confirmed suitable for the application β€” kiln-dried (KD) for framing, appropriate rating for exterior use
  • Pressure treatment level confirmed to match the specific exposure category β€” ground contact, above-ground, or interior
  • Fastener and hardware material confirmed compatible with the treatment chemical used
  • Each piece visually checked for grade-disqualifying defects before use β€” excessive warp, large knots, splits
βœ“Dimension & Quantity Verification+
  • Actual (dressed) dimensions used for volume, weight, and structural calculations β€” nominal size confirmed separately for board-foot billing
  • On-center spacing confirmed against the structural design or applicable building code, not a generic default
  • Required piece length confirmed available from the supplier before finalizing the order
  • Wastage allowance matched to the actual job complexity, not a single default figure for every job
  • Calculated piece count cross-checked against the framing drawing or takeoff, not relied on alone
βœ“Site Storage & Handling+
  • Delivered lumber stored off the ground on stickers/dunnage, not stacked directly on soil or a wet slab
  • Stacked lumber covered or protected from direct rain and prolonged sun exposure while awaiting use
  • Stickers (spacer strips) between courses aligned vertically above supports to prevent stack-induced warp
  • Pressure-treated lumber handled with the precautions on the treatment tag β€” gloves, dust control when cutting
  • Long pieces adequately supported during carrying and cutting to avoid cracking under their own weight
βœ“Structural Use & Fastening Verification+
  • Actual span checked against the specific species/grade/size combination's published span table
  • Fastener type, size, and spacing schedule followed as specified, not substituted informally
  • Metal structural connectors (joist hangers, hurricane ties, post bases) installed exactly where specified
  • Minimum bearing length at each support confirmed adequate for the piece's size and load
  • Notches and drilled holes for services kept within the size and location limits allowed for the member
βœ“Waste, Reuse & Disposal+
  • Usable offcuts sorted and retained for blocking, shims, or shorter framing needs before being treated as waste
  • Pressure-treated offcuts and sawdust disposed of per local regulation, never burned
  • Final as-used piece count, sizes, and any species/grade substitutions recorded for the project record
