ABSTRACT
The most sensitive features affected by the works were the railway tracks and the underground utilities, including drainage pipes and sewers, close to the alignment of the pipe jacking.
Prior to the commencement of works, a condition survey of the existing road and the structures within 25 m of the alignment of the pipe jacking and a CCTV survey of the existing drainage pipes and sewers within 20 m of the works were carried out. Another CCTV survey was also carried out on completion of the works.
