Projects: Civil Engineering
Client: Severn Trent Water
Location: Walsall
Programme: 37 weeks, ongoing
Work carried out: Excavating cofferdams and storage overflow chamber, installing pre-cast concrete culvert units, associated drainage and manholes.

The contract is located alongside the River Tame. Severn Trent Water required some form of storm water retention and flooding alleviation. We were brought in with G F Tomlinsons to install 170 ton of pre-cast concrete culvert units to a depth of 7m deep.

Interlocking sheet piles were driven 9m into the ground in an area of 70m x 24m, this was then excavated and framed up using a heavy duty shoring system, the culverts were then installed ranging from 14t to 28t using a 220t crane.

This site is a high profile capital expenditure contract requiring stringent quality and health and safety checks.
