Civils and Building Subcontract
Putney AFA is the most complex “Access for All” scheme undertaken by Network Rail, which involves the demolition, re-design and construction of the station building in a live public environment, with most of the building works taking place over live railways. The scheme also includes the installation of lifts and new stairs to all four platforms. One of the busiest stations in the country, Putney lies within a cutting, at the junction of the South Circular and Putney High Street. The severe access constraints to the site for this project has resulted in 1000’s of tonnes of materials and equipment being hand carried into the station from the surrounding roads, whilst the disruptive possessions, pre-booked a year in advance, are met as programmed.
A Nationwide Rail & C Spencer Alliance was formed at Contract Award in recognition of the project complexities, and to this, Nationwide Rail brought expertise in design development to suit the required construction techniques, complex temporary works design and experience in the delivery of complex multi-disciplinary projects around the operational railway.
From contract award, Nationwide Rail changed the proposed construction methodology to accommodate the extensive use of the station by proposing and constructing temporary bridges. This created access to the works completely segregated from the public and the operational railway, thus the opportunity to deliver the project during daytime working hours and with minimal impact on the 10 million yearly station users was realised. Nationwide Rail’s focus was on creating maximum High Street Environment working and eliminating ALO through careful consideration of the construction techniques.
Responsible for design management Nationwide Rail Value Engineered the design to specifically suit the logistics and restrictions of the station, and to eliminate a number of long term maintenance requirements.
The ongoing project is due to be completed months ahead of programme.
