Study Notes
Preparation for Construction
- Staking-out involves establishing boundary lines for foundation layout before construction begins.
- Batterboards are wooden boards placed at corners to guide excavation and foundation setup.
Formwork & Shoring
-
Types of Formwork:
- Lumber forms should be partially seasoned for strength.
- Plywood forms must be waterproof, Grade "A," and at least ½" thick for durability.
- Steel forms may be used for concrete joist construction and can include pans and decking.
- Phenolic boards are waterproof and mold-resistant, made from phenol and formaldehyde, ideal for various construction applications.
Construction Tools & Equipment
- Tools are categorized into four main groups:
- Hand tools reliant on manual power.
- Pavers for placing, spreading, and finishing concrete or asphalt.
- Compactors for soil and material compaction.
Major Parts of a Building
- Superstructure: Above-ground components of a building.
- Substructure: Below-ground, habitable components of a building.
- Foundation: The structural base transferring load to the soil.
Types of Substructures
- Slab on Fill: A slab built directly on the ground.
- Crawl Space: An unfinished area below the first floor, typically less than full-story height.
Soil Considerations
- Types of earth materials affecting foundation stability include:
- Loam: Contains a proportion of vegetable matter.
- Peat: Compressed vegetable matter influencing load-bearing capabilities.
Allowable Loads on Foundation Beds
- Prior investigation is essential to determine the allowable unit load on foundation beds.
- Uniform site conditions allow a uniform load, while varying conditions necessitate load adjustments to minimize differential settlement during construction.
