SITE INVESTIGATION ASPECTS OF THE SYDENHAM ROAD SEWER TUNNEL
This report, the first of a series of case history studies of tunnel projects made from the point of view of the site investigation, has been prepared with the generous co-operation of the Borough Engineer and Surveyor of the London Borough of Lewisham and his staff. Preliminary appraisal indicated London Clay under granular deposits. The site investigation contractor offered a very competitive price and subcontracted the boring and testing. Further boreholes for a route adjustment and for ground water measurements were put down by a drilling contractor employed and supervised by the Borough. The contractor found the site investigation fully adequate for tendering for pipe-jacking, and for specifying, tendering for and constructing the tunnel by the chosen alternative method using a shield and concrete segmental lining. Ground conditions at the face were systematically recorded. A number of services was encountered during construction, but no problems arose due to design, method of construction, or ground type or conditions.
