Client: Thomas & Coffey
Location: RAAF Base Williamtown (Ordnance Loading Aprons)
Scope of Works: Construction of taxiways, aprons and roadways. Project Value approximately$6m. Works included
- Clearing and bulk earthworks and improving the variable subgrade conditions caused by the previous land use of sand mining.
- Construction of airport pavements in accordance with stringent specifications for material supply, compaction and level control. Proving pavement with both Pneumatic and Solid Tyred MARCO Rollers.
- Works were constructed adjacent to the existing operational Williamtown RAAF base runway. Thus, issues associated with a live runway had to be considered. For example, site security, foreign object debris (FOD), firm program requirements and aircraft noise.
The OLA project had a number of very sensitive environmental aspects that required careful management
- Working on permeable sandy soils “The Tomago Sandbeds” which are used to supplement Hunter Waters supply.
- Protection of threatened plant species “Eucalyptus parramattensis subsp. decadens”
- Implementation of a management plan to prevent spread of “Phytophthora cinnamomi”, a soil-borne water mould that has the potential to cause widespread dieback of native vegetation
