Our Management
As with neighbouring Steven’s Weir, this project experienced record-breaking rain and floods, causing repeated withdrawal from site, with accompanying re-establishment and repair work.
Throughout, CivilTeam managed to maintain an acceptable working relationship with the client and the respect of project stakeholders.
Value Adding
CivilTeam were proud to finally hand over the project that met all the client’s requirements and drew positive comments from both locals and project stakeholders.
