Relevant sustainability targets andinitiativesexternally audited. ANDWaste handling and disposal/recycling all theway to final destination has been audited atappropriate intervalsSourceSuggested approachTargets and initiatives potentially relevant to the proposal depending on final scope5.16 – Permeable and porous surfaces –Design for permeable and porous surfaces toallow for stormwater infiltration (preferablywith other treatments such as vegetatedswales)SDGAt present there is likely to be limited scope forthe use of permeable pavements, aspavements would need to match what isalready there. However, if the scope changesto include any significant footpath works wherethe proposal team can influence type ofpavements used, this initiative would apply.7.53 – Heat islands – Use light colouredmaterials and vegetation on roofs andpavements to both shade from and reflectsunlight, in order to decrease heat islandingSDGAt present there is likely to be limited scope toaddress this target, as pavements would needto match what is already there. However, if thescope changes to include any significantfootpath works where the proposal team caninfluence type of pavements used, thisinitiative would apply.Note: TPD – Transport Projects Division of Transport for NSW; SDG – Sustainable Design Guidelines version 2.0 (Transportfor NSW); AGIC - Australian Green Infrastructure Council Infrastructure Sustainability frameworkAs noted in Table 12.1, the proposal provides an opportunity to address the sustainability targetof diverting 90 per cent of waste from landfill. The greatest opportunities for sustainability gainson the proposal could be achieved by focussing on the reuse and recycle stages of the wastemanagement hierarchy (see Figure 12.1) as set out in the NSW ‘Waste Avoidance andResource Recovery Strategy’ (DECC 2008). Possible options for reuse and recycling would bedeveloped in consultation with the contractor/s, in line with feasibility and sustainabilityoutcomes.As noted in section 4, a ROI process was undertaken to determine market interest in removingand buying the Monorail infrastructure. The ROI process closed on 12 October 2012. Options toreuse all or part of the Monorail infrastructure are currently being assessed.The potential impacts and opportunities relating to materials and waste are considered further inthe following section.In summary, the key sustainability opportunities for the proposal are considered to include:• reusing infrastructure that forms part of the Monorail• maximising recycling and minimising waste to landfill where reuse is not feasible• reducing the quantity of Portland cement used in footpath restoration works wherepossible• developing a detailed waste management plan for the proposal.118 | GHD | Transport for NSW - Monorail Removal Project REF
Figure 12.1The waste management hierarchy12.3.2 Materials and wasteWaste generationAs the proposal involves removing a significant piece of transport infrastructure that extends forapproximately 3.6 kilometres and includes a number of built structures, it would result in thegeneration of large quantities of waste. Waste generated by the proposal would include:• structural steel from removal of track infrastructure, including beam and columns, as wellas steel associated with stations• concrete from removal of the footing pads and stations• electrical cabling from removal of wiring• industrial waste such as lubricating oils, hydraulic fluids and cleaning agents• transformers and associated infrastructure from substation decommissioning.The estimated quantities of the main waste types that would be generated are provided in Table12.2. These estimates were provided by Evans & Peck and are based on the removalmethodology outlined in section 5.Table 12.2 Estimated quantities of key waste types generated by theproposalType of waste Current use Estimated quantitySteel Beams 1,383 tonnesColumnsSteel reinforcingStations111 tonnes3 tonnes60 tonnesConcrete Pedestals 112 m 3Stations 300 m 3GHD | Transport for NSW - Monorail Removal Project REF | 119
