Bristol Airport

Our ongoing, multi-million pound renovation and extension works at Bristol Airport will enable 10 million passengers to pass through each year.


Bristol Airport is the UK’s fifth largest airport outside London and the ninth largest in the UK, handling over 6.3 million passengers in 2014. With passenger numbers reaching record levels year on year, the airport embarked on a major redevelopment plan to meet increasing demand and deliver its 2006-2030 Master Plan. 

The phased development plan is being delivered through 30 separate component projects. These include the expansion of the passenger terminal, additional aircraft and passenger car parking, walkways, public transport interchange, fuel storage and office buildings. 

Hydrock was appointed to undertake civil and structural design and geotechnical consultancy services for the East Terminal extension, central pier and walkway, as well as various interventions in the existing terminal, including a new executive lounge floor slab, new escalators and stairs in departures, and new stairs within the arrivals lobby. Completed in 2015, the new eastern pier and walkway structure provides access for four new boarding gates and includes a bridge link to the existing terminal and business lounge.

The West Terminal extension, currently at construction stage, will be a three storey structure incorporating a single storey basement of predominantly concrete frame construction, with a steel frame to the front elevation. 

Each part of the design and construction process for these projects is complex, necessitating the consideration within the structural design of geotechnical issues around potential solution features and safety requirements for blast resistance.

Other considerations for working airside have included security procedures and restrictions, linking the newly constructed elements with the existing live terminal building, and night time working to minimise the impact of the works on passengers.

The expansion works undertaken by Hydrock have enabled the airport to increase its capacity as it manages more passengers than ever before, whilst ensuring a smooth transition through the airport and its component parts for all travellers. Passengers now have a greater choice of retail options and areas to sit and relax in, as well as an overall increase in destinations and flight options.
