Performance outcomes
By the end, you can:
- 1Explain why stair uniformity is a safety requirement.
- 2Identify guard and handrail information requiring local verification.
- 3Prepare a final deck quality record.
Working vocabulary
Name it precisely.
- Total rise
- Vertical distance from the lower finished walking surface to the upper finished walking surface.
- Unit rise
- Vertical height of one step.
- Guard
- A protective assembly at an open-sided walking surface.
- Handrail
- A graspable component intended to support stair users.
01 · Instruction
Solve stairs from finished surfaces
Measure total rise between final elevations, select a compliant number of risers through the approved process and calculate uniform unit rise. Account for tread and landing thickness before cutting stringers.
02 · Instruction
Prototype before production
Lay out one stringer, verify every line and test fit before copying. Preserve required material at cuts and use approved support and connection details. Do not “tune” unequal steps after installation.
03 · Instruction
Close the inspection record
Check structure, connectors, stairs, guards, handrails, surface fasteners, drainage and interfaces with the building. Record measurements and corrections.
Execution checklist
- ✓Rises and runs measured
- ✓Guard and rail attachment documented
- ✓Connector inspection complete
- ✓Water paths open
- ✓Punch list closed
Concept diagram—not a construction drawing. Dimensions, connections and approvals come from the project documents and local authority.
Field assignment
Stair and guard review
Create a dimensioned stair worksheet and perform a mock final inspection.
Evidence to capture
- Finished-elevation calculation
- Pattern-stringer verification
- Guard/rail detail reference
- Closed inspection checklist
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.
Circular saw and jigsaw/hand saw →
Cut a verified stringer pattern without overcutting corners.
Impact driver →
Install specified stair and guard connectors.
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.
