The £9.2m scheme has been let under the Project Allenby/Connaught contract.
Rydon is already on site following a tree planting ceremony, led by commanding officer Major General Colin Boag. The new headquarters will be completed in January 2014.
Rydon southwest regional director Paul Barber said: “Securing the Army HQ Support Command building is tremendous news for Rydon and testament to the standard of work for the MoD from our Bristol office.
“Having delivered 20 buildings for Aspire Defence’s Allenby/Connaught contract, we look forward to continuing our excellent working relationship on this important scheme.”
The building will contain 55,000 sq ft of open plan office space across three floors, connected by two atria. Two main entrances will be linked internally by circulation space through the ground floor forming a ‘street’ accessing the atrium spaces. The floors will be completely open to the atrium, providing views across the office areas.
External features include a slate tile roof, masonry envelope, curtain walling aluminium windows and a Brise Soleil system. Internal finishes include porcelain floor tiling and decorative wall panels to the entrance atria with glazed roofs.
Rydon recently completed the refurbishment of Government House Officers’ Mess in Aldershot, a Grade II Listed property hosting official events and functions for the Army.
