Parsons Brinkerhoff has landed the programme manager’s job on the ambitious project to extend the East London Line.

The firm will run the main £900m contract, which involves replacing all existing railway lines and building new tracks, signals, viaducts, crossings and four new stations for Transport for London.

Programme manager Ashok Kothari will lead the team assigned to the project. He has spent the past 15 years leading the team on the £1.6bn San Francisco Bay Area Rapid Transit extension programme.

Work has begun on the East London Line extension and it is hoped that contractors will start on site by June 2006. Separate engineering work to replace 21 bridges is already under way and due for completion within 12 months.

The main project is due to finish in December 2010. The station developments will include the complete replacement of Shoreditch Station and the creation of new Tube stops at Hoxton, Haggerston and Dalston Junction.

TfL is spending £10bn over five years on projects aimed at improving transport in south and east London.

Parsons Brinkerhoff is a multidisciplinary company headquartered in New York.
