UK-based Network Rail has engaged with Carillion to construct a 50m flyover, in the form of a single track viaduct, as part of the 2.3bn London Crossrail project at Stockley in Hillingdon, to enabling Crossrail services to operate to Heathrow.
Jacobs Engineering has undertaken the design of the Stockley viaduct in the Heathrow Airport Junction which will allow Crossrail trains to join the branch to Heathrow without delaying, or being delayed, also providing a separate route for fast trains to the west, thus increasing capacity and reliability on the extremely busy Great Western Mainline. SSL have carried out the design for all signalling works.
Active are currently carrying out demolition enabling works for the new construction of the viaduct and removing the asbestos roof sheeting to existing factory units. Namely; Ford Servicing, Ford Retailing, all Point Packaging, HG Timbers, Heathrow Motors and KGM Transport – works are currently on-going.
The viaduct will start begin on the western side of the existing airport lines, and cross over all tracks in the railway corridor and turning eastwards to continue on the northern side of the existing railway tracks. The viaduct will then widen and a to allow the junction for Crossrail and Heathrow Express services will be to be installed on the track.
The works are due to complete in 2017.
Crossrail trains will pass through 37 stations and run 118km from Maidenhead and Heathrow, via new twin-bore using 21km tunnels below central London to Shenfield and Abbey Wood.
When Crossrail opens it will increase London’s rail-based transport network capacity by 10% and is also expected to offer the ability to travel directly to the West End, the City and Canary Wharf.
With an eight-week programme and restrictions to on-site traffic, due to the live shopping complex, the project was highly demanding yet completed within time, on budget and most of all safely.
As part of the works, Active had to protect and retain external boundaries, UKPN electricity sub-station, street furniture within confines of the site, front car park and paving, inclusive of soft landscaping. As Main Contractor, Active established the site equipped to undertake the works conforming to CDM 2007 regulations and Health and Safety at Work Act. Site welfare provisions exceeded the minimum requirements of the Construction (Design and Management) Regulations 2007 and the smoke-free (Premises and Enforcement) Regulations 2006.
