PROJECT BRIEF: Tender to Construct 4 x Compliant Tennis Courts on an Asphalt Pavement. Works to include earthworks, excavation, crushed rock base, Asphalt Pavement, Fencing, LED Lights and book a court system, Acrylic Hard Court Surface, Furniture, footpaths, viewing areas.

Cardinia Shire Council put out to Tender, this project which involved the demolition of two existing Tennis Courts and the construction of 4 x new tennis courts at Cochrane Park Tennis Club in Koo Wee Rup.

A.S.Lodge were grateful to the Cardinia Shire Council for being chosen to build these courts along with a further two in Catani which was another Tender run concurrently. Initially the council was keen to adopt a flexible pavement using fine crushed rock and asphalt. However once the initial site strip was performed it was obvious the CBR of the subgrade was insufficient to hold a flexible pavement without extensive improvement and cost. Our design team put together a proposal to construct a heavy duty concrete pavement which was adopted by the council engineering department.

The project required earthworks to the existing sub-grade to get it to a standard capable of supporting the new pavements, and then the importation and placement of a 100mm capping layer of Class 2 Crushed Rock. A 150mm reinforced (SL92) concrete pavement was adopted and installed complete with stiffening edge beams.
The main drainage to be installed , consisted of 225mm UPVC pipes and associated pits, which was then discharged to the existing storm water system of Cochrane Park 

SUMMARY
We at A.S.LODGE were able to construct these courts in direct line with the specification, design and other tender requirements.

Low level LED lights were designed to minimise any light spill to the surrounding residents. This low level lighting was still able to present in excess of 400lux per court (PPA) and with a uniformity of 0.75 these lights were wired back to a Book-a-Court control system that allowed for public access to the courts in line with council philosophy.

The resulting facility provides a state of the art , attractive, modern and fully serviceable Tennis Court Facility to the Cardinia Shire and its constituents. We at A.S.Lodge are both grateful and proud that we were given the opportunity to be involved in this impressive infrastructure project.

PROJECT BRIEF: Reconstruct 4 courts that had become unusable due to subgrade movement. It appeared as if a natural water stream had risen under the courts which had made the entire pavement completely unstable. It was necessary to design and construct the 4 courts to the highest level and in doing so improve the total amenity by installing the latest in LED lighting and new retaining walls to stabilise the surroundings. The courts were to allow for 4 tennis and 2 netball courts to accommodate the needs of the community.

After stripping the old pavement away from the existing surface the full extent of the pavement failure became evident. Any subsurface drainage that had previously been installed had failed or had been damaged during previous works. The subgrade was described by our engineers as ‘soup’.

Our engineers designed a series of AG drains to drain the subgrade. These were put in at depth of approximately 1200 mm. once we were happy that the majority of the free water had been extracted from the subgrade we excavated 900 – 1000 of the unstable material and removed it from site. A Tensar grid was installed over the exposed subgrade and layers of crushed rock / clay fill was installed to gain a stable working platform upon which the courts court be constructed. A further layer of geogrid was then installed prior to further layers of 40mm crushed rock. Our team them excavated stiffening beams around the perimeter of the courts to ensure a sound and stable pavement could be constructed.

Our design team them selected a 150mm reinforced concrete pavement to counter any future sub-pavement movement . this was designed with all the necessary expansion joints and the like to present a long lasting playing surface.

Full high level LED lighting was installed to the 2 main tennis courts complete with stand alone switching cabinet and controls. These lights were tested to show an average 365 lux over the PPA which was an excellent result.

The club were intent on the highest level playing surface for its members. They finally chose our top rated HAS cushioned acrylic, supplied by CSS. This involved adhering a 4mm rubber mat to the prepared concrete base. Multiple layers of acrylic filler were applied prior to the final playing surface. The southern courts were coated with Plexipave acrylic surfacing and lined for both tennis and netball thus presenting a perfect multiuse facility.
