Project

Client: Tubelines Ltd

As part of the PPP Contract, Tubelines was required to undertake inspection and assessment of all assets for which no current inspection/assessment had been undertaken: 'Grey' Assets.

The programme of works comprised a three year commission to undertake inspection/assessment of all 'Grey' lineside assets on the Jubilee, Northern and Piccadilly lines.

This involved various structures such as retaining walls, pump houses, signal gantries, footbridges and such like.

Undertaken between 2005 and 2008, Roughton provided the planning and execution of the inspection and assessment of approximately 380 individual structures on the Jubilee, Northern and Piccadilly lines, including: 

• AIP (Approval in Principle) to detail the proposed assessment methodology
• Principal Inspection Report and associated CAD drawings prepared in accordance with LU/TLL Standards
• Assessment calculations prepared in accordance with approved AIP
