This was a complex, multi-disciplinary engineering project and the design needed to address extremely challenging site constraints imposed by available land area, close proximity to neighbouring houses, ground conditions and existing infrastructure.
Some particularly innovative design and project delivery approaches used for this project include:
- design of an interlocking secant pile wall structure to enable construction within such a confined area without the use of sheet-piling which would risk vibration damage to neighbouring houses
- utilisation of 3-dimensional modelling software for the design of the pump station, which ensures the various complex elements of the design fit together as intended
- using a combination of mains power and on-site diesel generation to power the pump station in order to minimise long term cost.
