Crown Reserve 38883 is known locally as Yaringa Quarry. The reserve is best described as a mesa ridge aligned north – south that is dissected by a creek. The reserve extends to include level areas west and east of the mesa. The target source rock and materials for road construction within the Yaringa Quarry are Clayey Gravel, Calcrete Duricrust and Toolunga Calcilutite. The source materials are limited a 6 metre thick horizon on top of the mesa. Approximately 80% of the total area available within the Crown Reserve has been investigated to identify approximately 540,000 banked cubic metres (bcm) of source rock suitable to be processed to various specifications for use in road construction. Project Scope Main Roads plan to produce approximately 612,000 loose cubic metres of road building materials from reserve 38883 to reconstruct the North West Coastal Highway (NWCH) in stages from 2017 to approximately 2021 as funds become available. As at June 2015, 540,000 bcm of suitable source rock in approximately 12 hectares has been identified within the Crown Reserve 38883. This represents a total of 720,000 bcm including topsoil and overburden. Some overburden material will be used to produce materials for less critical layers in the road pavement such as general embankment and sub-base. Design Capacity and Frequency It is estimated that the NWCH reconstruction project will require: Fiscal Year Product 16/17 17/18 18/19 19/20 20/21 Total (bcm) Basecourse (bcm) 45,000 42,000 42,000 42,000 42,000 213,000 Sub Base (bcm) 155,000 50,000 50,000 50,000 50,000 355,000 Estimated Total 3.70 1.83 1.87 1.90 1.94 11.24 Product Cost $M Main Roads WA will call tenders for the staged production of road building materials from the Yaringa Quarry. The annual tabled costs are the all-inclusive bases on current tendered rates and include and annual allowance for CPI of 2%. The tabled quantities represent an estimate of the quarry products required to a 55 kilometre section over 5 years and include an annual specific maintenance requirement of 20,000 lcm of sub base. Each tendered quantity required and labour costs may vary from that tabled, based on the available funding and the design requirement of the section of the NWCH to be constructed at the time. Each contract period is estimated to be approximately 10-12 weeks. Estimated Establishment Costs The Yaringa quarry has been used previously (circa 1975) by Main Roads’ contractors. Run of mine pads, access roads and hard stands have been constructed by earlier works. Subsequent works will re- establish this infrastructure. Document No: Page 3 of 5 Yaringa Quarry Estimated Road Building Production Program The delivered products will be stored on hard stands within the boundaries of Reserve 38883. As the hard stands have been established by earlier works they will require minimal regrading. Hard stands to accommodate products and plant shall be graded to flow the natural grades and will not significantly divert or impede the natural drainage, other than to collect and settle out sediments in silt traps Mobilisation/demobilisation costs will be dependent of the successful contractor’s base location. An allowance of $50,000 per contract year or a total of $250,000 for the project, for site establishment including mob/demob has been estimated for budgeting purposes. Key Infrastructure and Equipment Using previous similar works as a guide, Main Roads estimates that tenders will produce the required road building materials using conventional, mobile plant and portable camp. As the site has been used previously to produce road building material, only minimal site and erection works will be required to set the plant and commence operations. The mobile plant may consist of but not limited to: Pneumatic Drills and compressors Explosive magazines, licenced by the contractor Front end loaders Off road dump trucks Either Jaw/Cone and/or impact crushers Screen decks Conveyors and stackers Mobile quality control testing laboratory Mobile Camp* it is estimated that the contractor will utilise either the Overlander or Wooramel Roadhouses to accommodate employees, minimal camp will be onsite – ablutions and site office. Disposal and grey and black water will be at an approved Shire of Carnarvon site. Production Capacity To deliver the specified road building materials within the Main Roads timelines, it is estimated that the successful contractor’s plant shall have a minimum throughput capacity of 600-800 tonnes per hour. Estimated Labour and Plant Hire Costs The estimated total cost to produce the materials required of the NWCH reconstruction is $6.3M. The breakdown of the estimated cost is tabled below: Est. per annum Est. total Labour Hire $0.6M $3M Plant hire only $0.5M $2.5M Ground Water Investigation drilling, to a maximum depth of 8 metres, did not encounter any ground water. However, considering that the target material is calcite, it is possible that some minor quantities of contained perched ground water may be encountered. The risk of intersecting viable quantities of ground water within the Yaringa Quarry is considered very low as established by investigation drilling. However, if perched ground water is encountered Main Roads will liaise with Department of Water for appropriate approvals. Document No: Page 4 of 5 Yaringa Quarry Estimated Road Building Production Program Spoil Sites Any surplus quarry fines or overburden materials will be placed in two existing quarry pits on the north eastern side of the mesa ridge. The surplus/spoil materials will be graded and battered to reinstate the redundant quarry pits in accordance with the Main Roads WA Specification 303
