The £184M scheme to replace Gatwick Airport’s pier 1 involves demolition of the old pier and construction of a totally new facility in its place. It will accommodate five aircraft of a larger size than can be accommodated at the existing pier and they will have direct access via an air bridge, improving turn around times.
The building is designed around the baggage handling system, a new £45M ergonomically efficient system which will increase capacity from 3800 to 4250 bags per hour. The design of the building had to respect the radar line and the required height reductions were achieved with the help of a post-tensioned slab at first floor level. This slab carries the terminal facility over the baggage handling area.
The PT slab has a total area of 6690m² and has been constructed in 12 pours. The slab is 375mm thick and some of the heavily loaded internal columns benefit from a 900 x 900 steel shear head. To allow unhindered access into the baggage area below, several of the supporting columns are omitted along the front face and, instead, the PT slab is supported from a steel roof truss via tension hangers. The “L” shaped building measures 442 x 78.6m and typical grids are 12 x 12m.
The design relied heavily on BIM to identify clash detection and check access for maintenance. It also assisted in designing the baggage handling system to cope with various “what if” problem scenarios. The model also served as a useful training tool for the new staff prior to opening at the end of 2014.
CONSTRUCT AWARD WINNERS 2014
Freyssinet have been awarded the Award for Innovation and its Adoption at this years Construct Awards. The award is for our ongoing works at Hammersmith Flyover in London. The innovation relates to the use of Ultra High Performance Fibre Reinforced Concrete (UHPFRC) as a key element in the Post Tensioning (PT) strengthening system. Freyssinet is extending the life of key structures using advanced concrete with new techniques. The solution UHPFRC challenged the application of design codes, driving new techniques like the development of a unique concrete placement system. These innovations have the potential to change the way we think of future refurbishment of similar concrete structures.
The award and cheque was collected by Kevin Bennett, Sales and Technical Director and Ron Wilkinson, who were both thrilled by the accolade. The cheque was donated to the event’s chosen charity, The Lighthouse Club, who provide support to construction workers and their families.

“What a most interesting and enjoyable seminar! Your talks were most interesting, full of useful information […] and the trip round Hammersmith was really interesting because as far as I can see it’s are at the forefront of prestress, with the Ductal end blocks and 300m 37/15 tendons ending in blisters. All explained with great knowledge and patience. Thank you to all who took part.” AECOM
