Lancaster Storm Culvert Renewal - Lancashire

Working with Barhale for United Utilities, Grant Ltd have successfully completed the construction of a large storm water culvert on the city centre bus station site. Working in confined conditions, a large temporary works coffer dam was installed using vibro piling techniques.

Box section culverts weighing 14 tonnes each were then installed by crane and assembled in situ. This work involved the temporary diversion of live sewers and dealing with storm water run off during the project.

Castle Douglas WwTW - Dumfries & Galloway

Working with Carrillion for Scottish Water, Grant Ltd installed two large temporary works coffer dams for the construction of new waste water tanks. Dealing with a variety of ground conditions including running sand, dewatering techniques were used to enable the vibropiled excavations to be constructed using lateral trench support.
