Description

Objectives

Learning Objective 1 – Identify stairway components and related require- ments.

  • Define key stairway terms and building require.
  • Describe the types of stairways.

Learning Objective 2 – Describe how to determine the total rise, number and size of risers, and number and size of treads needed for a stairway.

  • Summarize how to calculate the riser height, tread depth, and total run for a stairway.
  • Describe how to calculate stairwell opening sizes.

Learning Objective 3 – Restate the procedure for constructing stairs.

  • Explain how to lay out, cut, and build stringers and concentrate forms.

Performance Tasks

Performance Task 1 (Learning Objective 2) Calculate the total rise, number and size of risers, and number and size of treads required for a stairway.

Performance Task 2 (Learning Objective 3) Lay out and cut a stringer.

Course Sessions

Session One,  introduces stairways and stair components.

1. Show Session One PowerPoint® presentation slides.

2. Provide an overview of the module.

3. Identify types of stairways and their components.

4. Locate sections in the International Building Code® and International Residential Code® that pertain to stairs.

Session Two, introduces stair framing terminology.

1. Show Session Two PowerPoint® presentation slides.

2. Discuss stair framing requirements for residential structures. Contrast the requirements to those for commercial construction.

Session Three, introduces stair calculations.

1. Show Session Three PowerPoint® presentation slides.

2. Explain the mathematical relationship between the riser and tread dimensions. Discuss how a change in one of the dimensions will likely impact the other dimension.

3. Discuss how to determine riser height.

4. Discuss tread depth and total stair run and how these dimensions are determined.

5. Discuss preframed stairwells and explain how to determine their unit rise and run.

Session Four, introduces stair construction.

1. Show Session Four PowerPoint® presentation slides.

2. Discuss the importance of safety when constructing stairs. Craftworkers must work from heights, which introduces another safety hazard. Emphasize fall protection equipment that may be used when constructing stairs.

3. Explain how to lay out and cut a cutout stringer.

Session Five, is a review and testing session.

Have trainees complete the module Review Questions and Trade Terms Quiz. (Alternatively, these may be assigned as homework at the end of Session Four.) Answer any questions that trainees may have.

1. Have trainees complete the Module Examination. Any outstanding performance testing must be completed during this session.

2. Record the testing results on NCCER National Registry, and submit the report to your Training Program Supervisor.
