Earthwork is about creating the right ground conditions before the next trade arrives. Elevations, drainage, subgrade stability, imported material and compaction all affect the result.
What this work usually includes
- Confirm the finished use and required limits for site preparation.
- Review machine access, overhead and underground constraints before mobilization.
- Identify material that will be reused, stockpiled, hauled away or replaced with aggregate/fill.
- Plan drainage, elevations and restoration so the excavation does not create the next site problem.
- Construction lot clearing and stripping.
- Cut-and-fill to reach design elevations.
- Building-pad subgrade preparation.
- Rough grading and drainage shaping.
- Aggregate placement and compaction before construction.
Common site preparation projects
Site preparation can be a multi-stage scope. It may include clearing, stripping, bulk excavation, fill import, rough grading, compaction and aggregate base rather than one simple excavation line item.
What should be clear in the quote
Two quotes that both say “site preparation” may cover very different work. One may include excavation only. Another may include haul-off, imported granular, compaction, rough grading and cleanup. Compare the written scope, not just the total price.
How the work usually moves
Define
Confirm the intended finished result, dimensions, elevations and related trades.
Locate & prepare
Address utilities, access, removals, permits or approvals that apply to the project.
Excavate & handle material
Dig, move, stockpile, export or replace material according to the site plan.
Backfill, grade & restore
Complete the groundwork needed for the next trade or finished surface.
Site Preparation questions
What does site preparation usually include?
The scope can include layout, excavation, material handling, grading, backfill, compaction and restoration depending on the project. A site-specific quote should say exactly what is included.
How is site preparation priced?
Price normally depends on access, depth, soil, water, equipment, haul-off, imported material, compaction and restoration. Machine hours alone rarely describe the whole job.
Do I need utility locates before digging?
Where excavation could affect buried infrastructure, required locates should be arranged before digging. The contractor should confirm what applies to the specific site and scope.
