Performance outcomes
By the end, you can:
- 1Transfer a support grid from control lines.
- 2Verify footing and post conditions against approved documents.
- 3Inspect beam bearing and built-up member fastening.
Working vocabulary
Name it precisely.
- Tributary area
- The portion of a surface whose load is carried by a particular member or support.
- Footing
- A foundation element spreading structural load to soil.
- Post base
- A connector restraining and separating a post at its support as designed.
- Built-up beam
- A beam assembled from multiple plies connected to act together.
01 · Instruction
Control the grid
Establish building and deck baselines, locate support centerlines and verify diagonals. Protect layout references from excavation so the same grid can check installed posts.
02 · Instruction
Inspect what will be buried
Confirm location, excavation condition, required depth and size, reinforcement where applicable, and utility clearance before placement. Use the approved inspection process.
03 · Instruction
Set a reliable beam plane
Verify post plumb, base and cap installation, beam bearing, ply orientation and specified fastening. Record top-of-beam elevations before joists spread the error across the deck.
Concept diagram—not a construction drawing. Dimensions, connections and approvals come from the project documents and local authority.
Field assignment
Support-grid verification
Lay out a scaled support grid and complete an inspection form for a sample footing, post and beam.
Evidence to capture
- Baseline and diagonal measurements
- Support centerlines
- Connector schedule
- Top-of-beam elevation record
Supervision rule: use qualified supervision whenever the assignment involves unfamiliar tools, energized equipment, structural work, excavation, work at height, or any condition outside your demonstrated competence.
Tool loadout
Tools earn their place by the operation.
Eye and hearing protection →
Baseline PPE for cutting and fastening operations.
Tape, square and marking tools →
Establish, transfer and verify dimensions before cutting.
Rotary laser →
Control footing, post and beam elevations.
Impact wrench or driver →
Install specified connector fasteners to required procedures.
Tool links are a shopping convenience, not a requirement to buy. Equivalent equipment may be appropriate when it matches the operation, material, accessory, capacity, guard, and manufacturer instructions.
Mastery check
Prove you can make the call.
Answer all three questions. The passing standard is 80%, so this short check requires 3 of 3. Explanations appear after submission.
