When completed in 2023, the 33km WestConnex project, also called the M4 tunnel, will connect the northern beaches of Sydney, western suburbs, Sydney Airport and southern suburbs.

This tunnel passes directly beneath the Cintra Park Hockey Complex and requires the entire facility to be reconstructed on the other side of Gipps Street.

THE CHALLENGE

The construction of the M4 tunnel required an exhaust shaft in the location of the Cintra Park Hockey Facility and subsequently the facility, consisting of hockey pitch, pavilion and carpark had to be reconstructed on the other side Gipps Street.

Canada Bay Council required the facility to be a like-for-like redevelopment while also complying with FIH requirements.

 

The nominated site for the relocated hockey pitch consisted of contamination and un-controlled fill. In addition to the undesirable ground conditions, there was a significant level change from the pitch level and the carpark.

THE SOLUTION

FIH National Standard ‘wet’ pitch

The hockey pitch was designed to be a FIH National Standard ‘wet’ pitch which required an irrigation system to apply precipitation across the surface within the FIH stipulated timeframe. The like-for-like objective meant that a water treatment facility was to be included to treat surface run-off from the pitch and re-use in the irrigation system.

A switch-back DDA compliant ramp

A switch-back DDA compliant ramp was required to enable universal access from the carpark to the pavilion and hockey pitch.

THE RESULTS

The facility opened in time to enable old facility to be decommissioned and construction works on the exhaust tunnel to commence. The facility was tested and found to comply with the FIH performance requirements and has been successfully used by the Briars Hockey Club since.
