Excavation & Back Filling
- Earthwork in excavation and backfilling of soil up to the required depth is required for the construction of foundation and trenches. The proper sequence of excavation and backfilling is required to optimize the process and prevent safety issues. Excavation and backfilling of soil is a very important part of the construction process, and care must be taken while excavating from a safety perspective.
- Different soil layers may be encountered while excavation, dewatering may be needed sometimes. These points must be kept in mind to take necessary action during excavation and backfilling.
- Correct measurement of excavation and backfilling is required because excavation cost is a major part of the foundation construction.
Scope of work for excavation and backfilling of soil includes;
- Setting out of corner benchmarks.
- Survey for ground levels.
- Survey for top levels.
- Excavation to approved depth.
- Dressing of loose soil.
- Making up to cut off level.
- Constructing dewatering wells and interconnecting trenches.
- Marking boundaries of the building.
- Constructing protection bunds and drains.
