D59 BAE Systems


The Brief

As part of the new Primary Build Capacity for BAE Systems’ submarine programme. This development would facilitate manufacturing requirements and scaling for the domestic defence-nuclear sector.

We are producing the new fabrication and assembly buildings for the D59 BAE systems development. This includes the steelwork to support a number of cranes with maximum loading of 150t.

Our Approach

  • The project’s framework had to be designed to consider the impacts of fatigue over the life span of the buildings. This is a practice we have been championing, so design and fabrication required Execution Class 3.
  • The D59 building is a multi-level portal frame with trusses, long span rafters, pre-cambered beams and connections to a concrete core.
  • This building required multiple specialised features in its overall design, such as durbar plating for walkways and specialised treatment requirement. Meaning supply and installation required high levels of expertise and coordination.

The Outcomes

We were awarded by Morgan Sindall a perfect delivery Certificate during 2017-18 period of construction. And we are still delivering steelwork to site as of 2020. 

In total we have supplied 200+ changes, over the course of the project programme and we continue to tailor the client needs to the structure. We have subsequently been awarded the honour to deliver the next stage of this development in 2021.

“The complexity and scale of the site, coupled with the building’s design requirements meant that the project required a team with particular expertise”
