ASD Westok has a long history of involvement with airport structures across the UK and Ireland.
A variety of airports, aircraft hangars, air traffic control facilities, heliports, airport distribution centres and associated buildings feature Westok beams. In particular, Newcastle, Bristol, Glasgow Prestwick, London Gatwick, Newcastle, Ballygirreen, Doncaster-Sheffield, Southend and East Midlands all feature Westok floor or roof beams in some fashion.
Closer to our home in Leeds, Westok boasts a long history of involvement at Leeds Bradford Airport. Westok beams incorporating service integration are clearly visible in the existing terminal building at check-in, in the retail and dining areas and finally at the boarding gates.
To facilitate an ambitious airport expansion programme, a phased redevelopment has commenced with one of Yorkshire’s most significant infrastructure projects of recent years with the construction of a new 9,500m2, £100M steel-framed three-storey terminal extension building, known as LBA:REGEN.
Considering Westok’s experience with airport facilities across the UK, it came as no surprise that the client’s consulting engineers Dudleys, requested Westok’s technical advisory service to support their work. Once again, Westok has teamed up with structural steelwork contractor Elland Steel to help deliver the project.
How the completed extension and the refurbished existing facility will look.
The new terminal building is 120m long × 41m wide with a regular internal grid of 12.5m x 11m, with variations closer to the perimeter. The clear-span grids reduce the number of internal columns, facilitating the desired flexibility.
The two upper levels of the new building connect directly into the existing terminal, and lightweight Westok beams were specified to ensure the floor levels matched whilst at the same time providing the required service integration needs of the structure.
In close collaboration with Dudleys and the wider design team, Westok engineers sized lightweight and structurally efficient 850mm ribbon-cut cellbeams with regular 500mm diameter cells, which were precambered at no cost in the Westok fabrication shop.
Certain beams were detailed with elongated cells to allow wider rectangular services to pass, and for a small number of very heavily loaded primary beams, Westok plate beams were designed and detailed.
The design of the ground floor beams was particularly complex owing to intricate loading arrangements and service runs in the baggage-handling area. In particular, a cellular beam solution was required to address an array of issues including service distribution runs, baggage conveyors, access platforms and baggage tugs, all within the tight head height constraints of the building.
Working closely with the design team, Westok engineers designed a flexible solution to address all of these issues.
