Site engineering and drainage
We prepare civil drawings and technical calculations for drainage improvements and developments, coordinating runoff management with practical site constraints.
Typical deliverables
- Existing and proposed grading plans
- Stormwater calculations and detention analyses, including HydroCAD where appropriate
- Drainage layouts, profiles and details
- Erosion and sediment control plans, including SWPPP, GESC or DESC documentation as applicable
- Site drainage and utility coordination
Information to provide
Boundary and topographic survey, proposed plans, soil or infiltration reports, rainfall criteria, discharge requirements and local authority standards.
