Key Concepts
Construction Materials
| Material |
Properties |
Common Uses |
| Concrete |
High compressive strength, low tensile |
Foundations, slabs, columns |
| Steel |
High strength, ductile |
Frames, reinforcement |
| Masonry |
Compressive strength, fire resistant |
Walls, foundations |
| Wood |
Renewable, easy to work |
Framing, formwork |
| Asphalt |
Flexible, waterproof |
Pavements, roofing |

Site Development
# Grading calculations
def cut_fill_volumes(grid, target_elevation):
"""Calculate cut and fill volumes from grid"""
cut_volume = 0
fill_volume = 0
for cell in grid:
elevation_diff = cell.elevation - target_elevation
volume = elevation_diff * cell.area
if elevation_diff > 0:
cut_volume += volume
else:
fill_volume += abs(volume)
return {"cut": cut_volume, "fill": fill_volume}
Regulatory Framework
- Zoning: Land use regulations
- Building Codes: Safety standards (IBC, IRC)
- Environmental: NEPA, EPA regulations
- Accessibility: ADA requirements
- Permits: Building, grading, utility connections
