A. Earthmoving and Heavy Construction
- Earthmoving: Process of moving soil or rock to meet construction needs. Processes involved: excavating, loading and hauling, placing, compacting, and grading/finishing.
- Earthmoving materials - soil and rock, characteristics include trafficability/loadability, soil types (gravel, sand, silt, clay), and organic materials.
- Soil classification systems - Unified System (two-letter symbols for coarse/fine-grained soils), AASHTO system (classifying soil).
- Soil conditions: Bank (natural state), loose (excavated/loaded), compacted (after compaction).
Construction Methodology
- Definition: Construction methodology refers to techniques used in building structures. It's a step-by-step procedure involved in infrastructure projects. It can be general or very specific/detailed.
-
General Classification:
- Earthworks
- Building Works (residential, commercial, industrial)
- Horizontal Construction (roads, bridges, dams)
- Specialized Construction (airports)
- Methodology in constructing a house: Processes like staking, excavation, structural works, walls, electrical/plumbing works and architectural work.
- Architectural Works: CHB Layering, Plastering, Doors/windows, Tileworks, cabinets/woodwork, Glassworks, and Painting.
