Airlinks utilise contemporary architecture and technology, and have been developed specifically for 21st Century airports. The units include full acoustic and thermal insulation to ensure a controlled internal environment. What’s more, a unique connector frame allows separate modules to be connected together, to give a walkway indefinite length.
Airlinks have been designed in accordance with Eurocodes BSEN 1990,1991 and 1993, and CE Marked in compliance with BE EN 1090. The concrete floor ensures compliance with SCI P354 “design of floors for vibrations: a new approach 2007” and the Concrete Centre “a design guide for footfall induced vibration”. Airlinks also comply with BAA Specifications.
Airlinks have a robust steel structure crafted to directly receive composite cladding, roofing and glazing. Airlinks are a fine example of lean construction; they contain so secondary steelwork flashings. Building services are fully integrated within the internal fitout: lighting, heating/air conditioning, PA system, fire detection/alarm, interchangeable double glazing, composite cladding, designed to accommodate ramp gradients up to 1 in 20 and spans up to 28 metres.
The footbridge which crosses the busy East Coast Main line Nr Peterborough, was opened mid-July following years of campaigning from local councilors and residents to improve safety at the crossing.
The crossing usage averages 200 plus school children pedestrians or cyclists per day across a 60mph main passenger line with 26 trains passing through this point.
Bourne was involved in the design stage allowing early collaboration from the outset with the client and Network Rail. The completed 240 meters of ramps, stairs and bridge section were fitted out with lighting electrics, handrails, GRP treads and paint work to ensure a “right first time” result before being placed by crane.
Winchester Station is a busy commuter station used by up to 86,000 passengers every week. The Bourne Group was commissioned with the erection of a footbridge, stairs and lift shafts at the station as part of Network Rail’s ‘Access for All’ campaign.
Bourne Special Projects erected the steelwork during overnight weekend possessions / blockades. Bourne were heavily involved throughout the design process, working closely with the whole design team to enable ‘completed’ elements to be designed, fabricated, and erected.
The completed 15 metre long, 25 tonne steel bridge structure was lifted into place by a 200 tonne mobile crane, within a one hour blockade, with the full height open inward glazed panels being the only missing components.
The frame dimensions required extensive fine tolerance surveying prior to the lift, as the bridge had to fit exactly. Very careful planning enabled us to complete the installation to plan, to the satisfaction of all parties.
This project consists of disabled ramps, a bridge and staircases that Bourne Special Projects provided as a modular solution to reduce the installation period.
As part of the service all components were finished with Protective Treatment N1 paint. BSPL also provided anti-slip flooring, stair nosing’s, drainage and containment for M&E which were all completed before the first lift.
Early collaboration with our client and Network rail ensured this project was on time and on budget.
Bourne Special Projects successfully completed the installation of the Custom House Excel Bridge during a 51 hour possession in December 2014.
The 34 metre long bridge has been installed as part of the construction of a new Crossrail station at Custom House, linking the station with ExCeL London. The new structure was lifted into place in three sections by two huge cranes with a combined weight of nearly a thousand tonnes.
Laing O’Rourke project director, Chris Warren, has said “What an awesome weekend. We`ve delivered on what we said we would, before the planned hand back time, and more importantly, without any incidents. An excellent result. Thank you for all your efforts and dedication, pure professionalism and commitment. A true example of how working as a team brings out the best results!”.
With Crossrail, the journey between Custom House and Bond Street will be around 10 minutes quicker and passengers travelling to and from Heathrow will be able to reduce their journeys by more than 30 minutes. When it opens in 2018, Custom House station will be run by Transport for London as part of London’s integrated transport network.
WestQuay is the premier shopping destination on the South Coast, designed over 3 storeys with retailing arranged over 2 floors and an upper level containing a 2,000 seat food terrace, this development has become the location of choice to the UK’s leading retailers.
At the time of construction WestQuay was the largest inner-city project of its type in Europe, the nature of the steelwork we provided was also quite remarkable. The focal space roof was formed with 14 metre span tubular trusses supported by branched circular columns. The entire steel roof structure had to be erected on a temporary scaffold support structure and lowered into position onto the branched circular columns. 20 metre boxed girders weighing approximately 50 tonnes formed the Portland Terrace Bridge. Their massive size deliveries meant that many roads around Southampton had to be closed when they were delivered. The roof over the bridge also had 8 welded trusses weighing 34 tonnes each. These were pre-fabricated at our works to enable the 350 tonne structure to be erected in just 8 days.
