|Project||Portsmouth Naval Base|
|Location||HMNB Portsmouth Naval Base|
|Value||Ranging from £5m|
|Scope||Structure/Maritime evaluation for upgrade/refurbishment for QE Class Aircraft Carrier operations: project management from Inspection, analysis, works to soft landing.|
Portsmouth Naval Base has been an integral part of the Portsmouth City since 12C. It is home to almost two- thirds of the Royal Navy’s surface ships, including the new aircraft carrier HMS Queen Elizabeth (at 65,000 tonnes, the biggest ship ever built for the Royal Navy), the formidable Type 45 destroyers, Type 23 frigates and mine countermeasures and fishery protection squadrons. It is a huge complex.
We provide specialist conservation advisory services to BAe through a framework supply chain. DA carried out building and structural appraisals plus design services throughout the built estate encompassing buildings and maritime structures. Some 200 heritage and high value, secure military structures over 5 years. We encompass the principles of BIM and Eurocodes.
Typical examples include:
Building 3-082 (100 Store): built as a factory in 1903 on the site of earlier timber sheds and brickfields. It is still the largest building in the Dockyard on a 180m by 85m footprint. By 1929 there was internal specialisation including torpedo, erecting and fitting shops. After various manufacturing functions it is now converted to a highly complex store with sophisticated robot operation and an electronically operated “dark warehouse”.
Trafalgar House: constructed in 1958 as an accommodation block for Warrant and Chief Petty Officers. The ground level footprint is about 45m x 38m, over seven storeys high as an “H” shape on plan.
Our condition survey for refurbishment, discovered that serious structural issues arose from steel frame corrosion requiring substantial emergency restorative works.
Dry Dock 6: A scheduled monument. From 1700, only the second stone alter step dry dock in the World (the first is to adjacent, left 1690).72m long, 25.3m wide and 7.7m deep. Use ceased after 284 years (1984).
DA carried out geotechnical investigations and proposed a scope of upgrade works in order to provide a structurally stable treatment in support of the new Victory Jetty designed to support the new Aircraft Carriers.
Delivery is dependent upon exceptional project management capability. Adam Desmonde has coordinated internal resources, multiple teams, project planning, feasibility analysis and close working with key stakeholders through the full project lifecycle including soft-landings.
