LOCATION:
A civils works package for the construction of a new battery energy storage system (BESS), part of Pivot Power’s energy superhub project.
The system stores electricity generated at off-peak times and returns it to the grid at peak times when demand increases.
Our works included:
- Installation of 19 Quantum cube slabs and NGET, earthing, LVAC and AUX substation slabs.
- Construction of access tracks into the site with type-1 finish.
- Installation of LV and HV and CCTV ducting along with nine CCTV cameras foundations.
- Installation of two areas of soakaway to control the rain and ground water, with areas of 464m2 and 154m2.
Challenges
A key challenge was the poor ground for infiltration with a high water table; this provided significant drainage design challenges with no option to provide positive drainage.
Programming was of key importance to ensure our customer’s timescales were met for equipment delivery and installation despite delays in providing design information.
Interface with the National Grid connection works was also important to ensure that the project met operational targets.
There were several client design changes that resulted in delays in obtaining design information, which had an effect on the programme.
Solutions
Close collaboration was required from project award with the designers and system suppliers to ensure a robust drainage system was designed and constructed.
We developed close relationships with the client designers and client-appointed contractors; we collaboratively developed an efficient programme for the works. It was also important to sequence works so that the programme could be maintained during the BESS equipment deliveries.
