The Green Horticultural Group were successful tenderers for the sports field reconstruction of the "White Oval" for the The Kings School, one of Sydney's oldest schools.
The oval construction began with the removal of the existing surface and soil profile. This involved scraping and stockpiling the profile and carting approximately 10,000 tonnes of material to suitable locations for re-use around the school.
The 'in-ground' works included a network of sub-soil drains and irrigation. The sub-soil drainage entrailed an intricate series of lateral collectors, mainlines and a ring main close to 3km in length. The irrigation was installed in conjunction with the drainage as close co-ordination was required to maintain the integrity and co-existance of all inground services. This was followed by the installation of a 100mm gravel layer across the entire 1.4 hectare surface, amounting to some 2,400 tonnes. This gravel layer will serve as a drainage layer allowing free movement of water to the subsoil drains and away to the collection tank for re-use around the school.
Following laser levelling of the gravel layer, a sand/soil blend was installed. We experienced significant wet weather through these latter stages. Out of the 101 day construction period, we encountered 31 wet days.
We then supplied and laid Legends Couch which we also used when we rebuilt Campbelltown Stadium and Knox Grammar School's Number 1 Oval. We worked closely with the school's curator to formulate a 'growing-in" fertiliser and maintenance programme to include aeration and topdressing.
Many thanks to GHG for a job well done in both the planning and execution of this project. The transformation of the oval has been simply phenomenal.
