Mount Druitt Commuter Car ParkReview of Environmental FactorsRecycled road base materials would be used where possible for the pavementconstruction.The anticipated type and approximate volumes of materials that would be generatedduring demolition include:Concrete –2500 tonnes; andReinforcement (including prestressing) - 70 tonnes.The existing ground floor slab would be retained and incorporated within the newground floor structure. No other on site recycling of construction materials isanticipated. The reinforced concrete that is removed from site could be crushed andthe concrete reused for granular material, and the reinforcing steel recycled.3.3.5. Traffic management and accessA primary consideration during construction would be the continued uninterruptedoperation of Mount Druitt Railway Station, Court House, TAFE and the surroundingbusinesses, and minimising inconvenience to railway commuters.Construction traffic would largely be limited to construction worker‘s vehicles,management staff and deliveries as bulk earthworks are unlikely at the site. Peakconstruction traffic of six heavy vehicle movements per day would occur during thedemolition phase. Construction traffic would be encouraged to use main roads as faras possible and entrances to the site would be clearly signposted.Approximately 85 per cent of construction vehicles would travel to the site fromCarlisle Avenue along North Parade. The remaining heavy vehicles would access thesite via Mount Street. Access to the site during construction would be via an entry/exitpoint on Mount Street.Further details regarding construction traffic management are provided in Section 6.1.3.4. Ancillary facilitiesThe demolished structure would be temporarily stockpiled on site and would beremoved efficiently and quickly. Stockpiling of other material would not be significantfor the Proposal and cut/fill works would not be substantial.The construction compound would be located along the site frontage to North Parade.The size and arrangement of this construction compound would be determined duringdetailed design. The construction compound would include site sheds, offices andmaterial storage areas as per normal construction practices.The construction site would be fully enclosed with security fencing to maximise safetyand security to the public. Hoarding would be erected along North Parade if required.Footpath works would generally be limited to the frontages of the car park alongMount Street and North Parade, however some minor footpath improvement worksbetween the car park and the station may be undertaken as necessary.No other construction facilities would be required for the Proposal.3.5. Public utility adjustmentsAn electrical substation and associated high voltage supply located towards thesouthern middle section of the site would require removal and a new substation wouldbe installed at another location on site. Other utilities present include electricalcabling, stormwater drainage and telecommunications. Details of these utilities andany necessary adjustments would be progressed during the detailed design stage.KMH-2010123a REF Rev 4 doc Page 25 of 116Status: Final
