Deck beam and joist framing before decking checklist

A pre-decking framing checklist for verifying beam size, plies, splices and bearing over posts; joist size, spacing, span, cantilever and crown; approved hangers, caps, clips and fasteners; rim and blocking; stair and guard-post reinforcement; concentrated loads and openings; lateral and diagonal bracing; field holes and notches; treated cut ends; drainage and ventilation around framing; alignment, level and temporary stability; and framing inspection photographs before deck boards or porch flooring conceal the structure.

Beam size, grade, plies, splices, fasteners and bearing match design

Critical item

Beam splices should occur only at approved supports.

Joist size, grade, spacing, span, cantilever and orientation match plans

Critical item

Framing geometry should support decking and loads.

Hangers, clips, caps and structural fasteners are correct and complete

Critical item

Every required hole and specified fastener contributes to capacity.

Rim, blocking, bridging, guard backing and stair support are complete

Critical item

Edge loads and future attachments need planned framing.

Holes, notches, splits and field alterations remain within approved limits

Critical item

Trade modifications should not weaken framing.

Frame is aligned, braced, inspected and photographed before decking

Critical item

Decking should not be used to correct unstable framing.

Use after structural framing and before decking. Do not load incomplete or unbraced framing. Do not enter unsupported excavations, work below suspended framing, climb incomplete structures, load unbraced decks, remove shoring or test guards by hazardous body loading. Structural changes, ledgers, stairs, guards, electrical work and elevated porches require appropriate design, permits and qualified construction.

    Deck post base and column before framing checklist

    A post and column checklist for confirming cured and undamaged footings or piers, correct post-base model, anchor embedment and corrosion compatibility, required standoff above concrete or grade, post species, treatment, grade, size and end treatment, plumb and bearing, caps and beam connection, temporary bracing, splice prohibition or approved splice detail, protection from water and soil, porch-column enclosure ventilation and complete photographs before beams, skirting or finishes reduce access.

    Deck lateral-load connections and bracing before decking checklist

    A concealed-structure checklist for verifying the approved strategy resisting side-to-side, front-to-back and uplift forces; inspecting house-to-deck hold-downs where required, post-to-beam and post-base restraint, knee or diagonal bracing, freestanding deck stability, tall post and multi-level conditions, stair and landing bracing, roof or porch-column loads, connector models and fasteners, corrosion compatibility, field conflicts and complete photographs before decking, ceilings, skirting or finishes make the load path difficult to inspect.

    Deck scope, permit and design before contract checklist

    A pre-contract checklist for defining deck or porch size, height, loads, roof or enclosure, stairs and guards; confirming property setbacks, easements, utilities and septic constraints; determining attached versus freestanding support; documenting existing house framing and cladding; obtaining approved structural and water-management details; specifying wood species, treatment, corrosion environment, connectors and fasteners; assigning permits, inspections, demolition, hidden-damage allowances, electrical and finish work; and comparing equivalent bids before signing.

    Deck footing before concrete checklist

    A pre-pour deck footing checklist for verifying approved layout and setbacks, utility clearance, excavation safety, undisturbed bearing or engineered preparation, footing diameter and shape, depth for frost and soil conditions, bottom elevation, groundwater and loose material, reinforcement where specified, forms, post-base or anchor layout, concrete access and weather plan, required inspection release and dimensioned photographs before concrete permanently conceals the excavation.
