Christ Church Grammar School identified some years ago, the future need for an increased number of sports fields and facilities to sustain the continual growth in pupil numbers. They purchased a parcel of land, formerly a part of the Brockway Road Landfill site, for the purpose of these playing fields. In 2015 the school had reached a point where the additional facilities were required and design work was initiated for construction.
The project included the remediation of the top 600 millimetres of the 86,000 square metre area with screening of this material to minus 15mm. Each screened material stockpile was analysed for contaminants and validated before being replaced over a layer of geofabric. This was then covered with a 100mm clean imported fill capping layer. The screened material was buried on site well below the finished field level in a selected location.
Additional works were added during the contract including the reconstruction and shaping of the Northern and Eastern boundaries. This required a further 4,000 cubic metres of imported fill material, a parking area, an access road and a slip lane on Stephenson Avenue.
By utilising 2 heavy duty power screens, over 50,000 cubic metres of the existing sand capping was processed to ensure that the project was completed on time.
