- MEP: Mechanical, Electrical, Plumbing
- Fire Protection: Detection, suppression, egress
- Communication: Data, security, AV systems
Infrastructure Types
- Transportation: Roads, bridges, railways, airports, ports
- Water Resources: Dams, levees, canals, water treatment
- Utilities: Power, gas, telecommunications, sanitation
- Public Buildings: Schools, hospitals, government facilities

# 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
