BAE Systems Maritime – Ship Fabrication Building – Substantiation & Strengthening Following Demolition of Adjacent Structures

The project involved the demolition of a series of existing structures at the Barrow Shipyard site in support of the forthcoming Successor Submarine Manufacturing Project.

SWA was appointed to undertake substantiation and strengthening of the retained 1900 building structure and foundations following demolition of adjacent structures. SWA’s scope also included the design of cladding proposals and access door to the newly exposed elevations and the provision of drainage proposals for the retained building and for the newly demolished area.
