A proper earthworks estimate separates excavation, reusable and unsuitable soil, imported materials, compaction, access and working depth.
From geometry to actual quantities
Initial volume comes from length, width and average depth, then profiles and levels refine it.
- excavation and movement on site
- loading, disposal and receiving site
- sand and aggregate supply
- layered placement and compaction control
Machinery and productivity
Excavator, loader, roller and truck selection depends on soil, work-front width, distance and constraints.
- access and working width
- utilities and depth
- soil moisture and bearing capacity
- haul and delivery distances
What to send
Provide a plan or sketch, sections, approximate levels, ground information, location and programme. If data is limited, begin with a site inspection.
