Transmission storage warehouses.

A critical infrastructure project to support the expansion of the electricity network through the design and construction of two new strategic spares warehouses for SSEN Transmission in Inverness and Dundee. The warehouses are strategically positioned to ensure a rapid response to failures in the transmission network and support the Government’s drive to net zero, connecting and transporting Scotland’s vast renewable resources to where they’re needed most.

The 7,500sqm warehouses incorporate heavy lifting facilities, bunded areas for oil filled plant, bespoke storage areas, and office and welfare areas for staff.

Appointed by SSEN Transmission, BakerHicks were responsible for the multi-disciplinary designs from concept, before being novated to the contactors, Global Infrastructure, for the detailed design and construction stages. The team also delivered statutory responsibilities including planning application input, support with the discharge of conditions and coordination with the SSEN Transmission appointed planner, as well as the submission of the staged Building Warrant for both sites.

A key aspect of the project was the development of a robust fire strategy for the storage of fully filled Transformers aligned to Building Regulations Storage Class 1. Working closely with BakerHicks' supply chain partners, the team developed an innovative design and fire strategy solution that accommodates complex requirements relating to the scale of the equipment and SSEN Transmission's operational procedures.

To promote both efficiency and safety for staff, the site and floor plan were thoughtfully designed to accommodate the diverse range of vehicle sizes used within the warehouses.

To accommodate abnormal loads, a one-way system, turning circles and junction clearances were integrated in the designs, providing the safe transport of equipment and general negotiation on site. A transport assessment also helped to finalise safe vehicle transport routes from the main motorways to the sites.
