Wakefield Flood Alleviation Scheme

CPC Civils were successfully awarded the Wakefield Flood Alleviation Scheme (FAS) contract in 2010 and completed works in 2013. The Wakefield FAS Project was a major flood alleviation scheme, split into several phases, to ensure protection within Wakefield for up to 1 in 100 year flooding, protecting 715 homes and 59 businesses as well as the A638 dual carriageway.

Ings Beck Flood Alleviation Scheme was a National Capital Project delivered under the NCF Framework. We worked closely with Galliford Try as their sole Civil Engineering Sub Contractor throughout the duration of the scheme.

The scheme itself was a strategic plan to provide the City of Wakefield with a 1:100 year flood defence. The project consisted of many different types of construction in order to achieve the required standard, and covered around 20 different working areas within the City itself. These ranged from 2 large Dam Structures including deep drainage, using large diameter concrete pipes, bulk earthworks, reinforced concrete structures and sheet piles through to minor concrete repairs on existing structures. We also undertook a substantial road crossing under the 6 lane arterial road into Wakefield without a single service strike. Further to this, other work was carried out in private gardens, public highways and retail developments.
Throughout the project we worked as close partners with the entire delivery team and constantly provided either best practice ideas or efficiency saving in the true meaning of partnering.

On Phases M to Q, CPC Civils installed a new bypass road built over the existing water course. To do so CPC Civils installed 110 meters of twin 3 meter by 2 meter pre-cast culverts. The culverts were fabricated off site by FP McCann, as a modular product, and installed by CPC Civils using a 120T Mobile Crane and culvert pullers. Furthermore, the innovation in using the culverts to divert a main road during the construction work won CPC Civils and Galliford Try the Exemplar Performance Award from the Environment Agency.

The works on the contract phase S to T were to widen existing brooks and streams to reduce flood risk, traditionally these streams were dammed off and over pumped whilst the works was carried out, we decided to temporarily divert the water course by burying a 600mm pipe beside the work area thus reducing fuel consumption and minimising risk of spillages of fuels and oils. Although overall there was very little cost saving there was a far greater saving from an environmental point of view as once the pipe was installed it did not require any maintenance.
