Clancy Rail – key contractor in ICE Civil Engineering Award

What is the ICE?

The Institution of Civil Engineers (ICE) Awards recognise excellence and imaginative concepts in civil engineering practice within London. The award identifies construction projects and promotes excellence in the engineering profession. This premier showcase for engineering excellence in the capital holds an annual award ceremony to recognise the engineering achievements within London. The flagship event hosts up to 200+ of the industry’s finest civil engineering contractors. The winners were shortlisted from 17 projects and seven were awarded trophies.

What was the overall project?

The East London section of the London Overground is a great success story with passenger numbers rocketing since the line was revamped in 2011. These increased passenger numbers meant capacity enhancements were needed with the Mayor setting a deadline of December 2014. The extra capacity has been created by increasing the length of the trains from four to five cars. This involved the delivery of a complex programme of platform lengthening, train stabling, signalling upgrades and maintenance facilities for the longer trains – a job that had to be done in just 20 months. A new depot has been built on contaminated wasteland at Silwood Sidings and a maintenance shed at New Cross Gate has been extended to fit the new trains in. All this had to be done without affecting daytime services or train maintenance – a job the project team finished on time.

What was the award for?

The awarded work facilitated the London Overground capacity improvement programme project to deliver 5-car trains on the East London Line in record time. Clancy Docwra acted as pre-enabling and phase 1 contractor at Silwood Sidings and managed the design and delivery of the scheme, working closely with the infrastructure maintenance contractors and London Overground to ensure the successful delivery for this award-winning project.

 “An increase in capacity has been achieved with very little intervention and cost, which will dramatically improve the service for commuters. This complex job was delivered without any impact on the service..” – Institution of Civil Engineers Judges

A big congratulations to all the Clancy Docwra team who contributed to the success of this significant project.
