This project involved the construction of a wavepool including plantrooms containing wave generation equipment, pumps, filters and air-conditioning equipment. The project includes a substation and a separate amenities / kiosk building. The wavepool itself has a water surface area of 4260m2.

The pool is constructed on reclaimed land and involves construction of heavy reinforcing with high crack control measures for all the floors and walls of the structure. A special high water resistant concrete mix was also used for the structure involving very strict quality control.

The pool is constructed over a piled foundation system involving in excess of 120 piles.

The installation of the reinforced concrete structure of the wave pool involved the detailed methodical planning procedures particularly in the floor area where a myriad of services needed to be cast below and within the floor amongst very heavy reinforcing and critical control joints.

The largest project challenge was to ensure that a watertight structure was constructed. This involved incorporating a controlled series of water stop control joints within the floor and wall structures and particular effort was required as to treatment of these joints where the wall and floor met. Constructability sequencing was managed around these joint locations. Due to its waterfront location, 24 hour dewatering systems were installed to maintain dry conditions to enable construction of below ground elements, throughout the various seasonal issues experienced through the wet and dry over 18 months of construction.
