Study Notes
Building Specifications and Planning
- Specifications include the types and quality of materials, construction methods, and structure location.
- Floor plans show the layout of spaces but do not display footings.
Floor Layout and Construction
- Floor plans indicate the location of floor openings for stairways.
- Wall panels in platform-frame structures are assembled on the subfloor.
- After raising a wall panel, secure it first to the subfloor.
Types of Framing and Materials
- Platform framing features individual units for each floor, enhancing construction flexibility.
- Sill plates are typically made from 2 x 8 lumber and must be treated when in contact with ground-related materials.
- Steel I-beams provide the greatest strength for structural support compared to other materials.
Construction Guidelines
- Girder pockets should be at least 1 inch wider than the girder, with a minimum wall bearing of 4 inches.
- The foundation's squareness should be checked before installing sill plates to ensure proper alignment.
- The first floor is framed prior to backfilling to help the foundation bear lateral pressure.
Leveling and Installation Techniques
- A level sill plate is crucial as any imbalance affects the overall structure.
- A plumb bob is not the recommended tool for checking a sill plate’s level.
- Use 8d nails at 6-inch on-center spacing when nailing a rim joist to the sill plate.
Joist and Beam Installation
- Joints of built-up beams should align over support columns for optimal strength.
- Joists should be end-nailed to the header joist and toenailed to the sill plate.
- Double floor joists are unnecessary under load-bearing interior walls that run perpendicular to joists.
Framing Openings and Components
- The rim joist is formed by two header joists and two end joists.
- Tail joists are short pieces installed parallel to common joists when framing floor openings.
Bridging and Subfloor Installation
- Bottom ends of cross-bridging remain un-nailed until after subfloor installation.
- When placing 4' x 8' subfloor panels, measure 4 feet from one side of the rim joist for proper alignment.
Structural Features
- Cantilevered decks or porches extend unsupported over foundation walls, requiring specific construction techniques.
- A material takeoff document summarizes required materials with dimensions for a job.
Measurement and Material Requirements
- For a 60' x 28' construction, 176 feet of 2 x 8 sill material is needed.
- Three 2 x 12s for a 60-foot beam necessitate 180 feet of material.
- A total of 53 panels of 4' x 8' subflooring is required for the same 60' x 28' area.
Advanced Systems
- Concrete joist systems use long pans or dome pans to create voids underneath slabs.
- Modular panel and pedestal systems are optimal in environments demanding extensive cabling infrastructures.
