Project Overview

As the appointed Civils Subcontractor, Hayward played a pivotal role in this prestigious project, involving the construction of a 20MW battery storage facility within a large water treatment works on behalf of the HV Electrical Subcontractor. The intricate nature of the work demanded meticulous planning and coordination among various key stakeholders, including the site owner – a major water company. The project required strict adherence to rules and procedures, with compliance to the BESS Principal Contractors stringent Quality, Environmental, Health & Safety requirements being essential due to the work being performed adjacent to live treatment areas.

Challenges and Triumphs

The DNO cable route was successfully installed across challenging terrain, overcoming various obstacles. These challenges included ecological concerns, including the potential presence of protected species, and arboricultural concerns involving protected trees and root zones. Operational constraints were also encountered, particularly as most of the cable route passed through an easement within the water treatment site and alongside live, often unmapped, assets.

Performance and Execution

Hayward’s team of multi-disciplined, skilled workers operated safely and efficiently to execute a complex work schedule which relied on “just in time” deliveries from multiple suppliers. The tasks included offloading, assembly and installation of galvanised steel sub structure supporting the batteries, PCS units, transformers and switchroom. From receiving, unpacking, orienting, lifting and installing the equipment, all activities were completed incident free.

Adaptability to Changes

The project encountered several design changes, prompting regular planning meetings and rescheduling key tasks to align with the critical path. Despite these challenges, the team seamlessly managed the adjustments, providing the client and principal contractor with regular updates through Hayward’s standardised reporting systems.
