Civil and structural works for a 132 kV substation, including equipment foundations, control building, cable trenching and site drainage, coordinated with the electrical installation contractor.
Equipment foundation setting-out tolerances were tighter than standard civil practice.
The electrical contractor's programme required foundations released in a non-sequential order.
The site had a high water table affecting cable basement construction.
Foundation setting-out was carried out with total station control and independently verified before every pour, with records issued to the electrical contractor at handover.
The construction sequence was re-planned around the electrical contractor's installation order rather than civil convenience.
The cable basement was constructed with a waterproof concrete design and external tanking, tested before backfill.
A joint weekly interface meeting kept foundation release dates and installation dates on a single tracked list.
