- A site ready for the next stages
What the service covers

- Footways, kerbs and pedestrian routes
- Existing utilities traced and coordinated with their providers
Our methodology
-
01
Survey and site setting-out
Existing levels are taken and network routes set out to the approved drawings, with existing utilities traced before any excavation starts.
-
02
Earthworks and formation
Excavation to the required level, then backfilling and compaction in layers, each density-tested and approved before the next.
-
03
Network installation and testing
Water and drainage lines laid to the approved gradients, with pressure and leak testing to the applicable regulations before final backfilling.
-
04
Trial operation and handover
Trial operation of the networks and completion of the surface works, with a documented handover of final test results and as-built drawings.
