Geotechnical firm Simplex Westpile, along with contractor Galliford Try, is in the midst of piling for a new basement and tunnel at the famous Wimbledon tennis courts in south west London.
The work involves foundations for a new basement under courts 14 and 15, and the tunnel for the new Somerset Road pedestrian link at the All England Lawn Tennis Club.
The £900,000 contract started in September and is scheduled for completion by the end of December. It comprises 1.2m and 1.5m diameter bearing piles, at depths of up to 35m to create the new basement. It also includes constructing a 750mm diameter by 13m long L-shaped contiguous bored pile wall with full length reinforcement cages.
The companies are also installing contiguous rotary bored pile walls as part of the construction of the Somerset Road Tunnel pedestrian link.
