Raynes Park

PROJECT DESCRIPTION

We were appointed with Careys Civil Engineering by The All England Lawn Tennis Club (AELTC), which runs the Wimbledon tennis championships, to deliver new grass courts at their Community Sports Ground in Raynes Park, South West London.

Package 1 of the project involves the provision of 16 No. outdoor grass tennis courts, 3 No. new acrylic tennis courts under an inflatable dome, winter sports pitches, services, site wide drainage and hard and soft landscaping. Package 2 involves the construction of a maintenance building with associated car parking, yard area and access road to Cannon Hill Lane.

BWB provided civils, structural, M&E, geotechnical and value engineering services. This includes the detailed levels, earthworks, drainage and external works design, structural design for the ring beams around the courts and the maintenance building, utility strategy and coordination. BWB were Careys chosen designer and therefore joined the project at Construction stage.

Key Challenges

Strict specifications for the courts to meet Championships standards have been set by AELTC. To ensure these are met we are working closely with the AELTC and its design team.

The tender design originally allowed for the 9 no. sets of 4 courts ring beams to be 1m deep with half of them being 800mm wide and the other half 1500mm wide. We reduced all the 1500mm wide ring beams to 800mm wide ring beams. We provided solutions to AELTC to reduce reliance on Thames Water supply to irrigate the court by detailing an abstraction borehole option. We simplified the tender drainage design by designing out the two Hydrobrakes initially specified by the previous Consultant and led discussions with the Drainage Officer to have this change approved. We reduced the build-up depths and therefore reduced the excess of material to be exported off-site. We re-designed the inlet and outlet of the pond using proprietary products instead of large gabion structures, saving the Client on cost and programme.
