MTH 98 or placement into MTH 65; placement into IRW 115 or WR 115

Course Description

Explores the rise and run ratio for stair construction. Includes material estimation and installation of both open and closed interior staircases. Emphasizes the relevant building codes in stair construction. Prerequisites: MTH 98 or placement into MTH 65; placement into IRW 115 or WR 115. Audit Available.

Course Outcomes

Upon successful completion of this course, students will be able to:

  1. Demonstrate safe practices associated with Construction industry.
  2. Identify the stair types and when they are used in a project.
  3. Calculate the rise-run ratio, riser size and stairwell length.
  4. Lay out stringers for given stair rise and run.
  5. Identify stair parts.
  6. Follow local building codes for stair construction.

Suggested Outcome Assessment Strategies

The determination of assessment strategies is generally left to the discretion of the instructor. Here are some strategies that you might consider when designing your course: writings (journals, self-reflections, pre writing exercises, essays), quizzes, tests, midterm and final exams, group projects, presentations (in person, videos, etc), self-assessments, experimentations, lab reports, peer critiques, responses (to texts, podcasts, videos, films, etc), student generated questions, Escape Room, interviews, and/or portfolios.

Course Activities and Design

The determination of teaching strategies used in the delivery of outcomes is generally left to the discretion of the instructor. Here are some strategies that you might consider when designing your course: lecture, small group/forum discussion, flipped classroom, dyads, oral presentation, role play, simulation scenarios, group projects, service learning projects, hands-on lab, peer review/workshops, cooperative learning (jigsaw, fishbowl), inquiry based instruction, differentiated instruction (learning centers), graphic organizers, etc.

Course Content

Outcome #1: Demonstrate safe practices associated with Construction industry.

  • Cleanliness of work area
  • Recognizing margins for specific tool safety – Red Zone
    • Saws
    • Drills
    • Hand tools
  • Maintaining tools in proper working condition
  • Safety rules of thumb:
    • Don’t force tools to do something they are not meant to do
    • Be present when using tools
    • Stay alert to what is going on around you

Outcome #2: Identify the stair types and when they are used in a project.

  • Understand the evolution of stairway construction
  • Identify the two types of stairs and their use
  • Calculate wider tread for winder stairs

Outcome #3: Calculate the rise-run ratio, riser size and stairwell length.

  • Distinguish between unit run and rise and total run and rise
  • Demonstrate accurate layout of stairway
  • Identify trimmers and headers to be used
  • Identify three rules for calculating rise-run and riser-tread ratio

Outcome #4: Lay out stringers for given stair rise and run.

  • Demonstrate riser height using a story pole
  • Use story pole to accurately transfer to a stringer and framing square
  • Identify three types of construction used for stringers
  • Demonstrate construction of a housed stringer stairway

Outcome #5: Identify stair parts.

  • Identify materials commonly used for treads and risers of main stairs
  • Describe basic stair riser shapes
  • Define the term “nosing” and the various designs associated with it
  • Identify the parts of an open stair

Outcome #6: Follow local building codes for stair construction.

  • Identify appropriate code that applies to stair construction
  • Read and interpret code
  • Follow and apply code standards
