Campbell Section 5 - Works Approval Project Ref: 110029Prepared for the Land Development Agency7.3.9 MaterialsMaterials for paths and light structures will be plain, robust and durable, and complementary to thenaturalistic quality and theme of water flow:FRP and concrete bridges and structures;concrete paths;gravel and concrete blocks along the ‘stream’ and as play elements; andsmall scale recycled brick paths through trees.Throughout the parklands and public domain areas of Campbell Section 5 a focus has been placedon providing a sustainable and maintainable public environment. This has been carried through thedesign in a number of ways:Selection of materials based on durability, ease of maintenance and sustainable materialsourcing;Emphasis on providing a range of habitat opportunities throughout the park for urban wildlifethrough meadow and native grass areas, provision of forested areas both native and exotic,and a permanent wetland area;Water management systems within the blocks, throughout the streets and as a central focuswithin the park provide best practice initiatives for recycling, cleaning, and reusing water.Swales, wetlands, rainwater collection, storm water day-lighting and porous paving are allstrategies for improving the quality of water moving through the site;By providing areas of mown turf and areas of longer native grass within the parkmaintenance is focused on high activity areas while other sections of the park requirereduced maintenance regimes; andMaterial selection within the public domain reflects the direction established in the CanberraCentre design manual. Lighting, furniture and paving has been selected to ensure ease ofmaintenance and replacement while still providing a distinctive and high quality urbanprecinct.Schedules of proposed exercise and play equipment included in Appendix 10 of this report.November 2012 Cardno 44
Campbell Section 5 - Works Approval Project Ref: 110029Prepared for the Land Development Agency8 Civil, Infrastructure, Servicing and ConstructionManagement8.1 Additional Studies8.1.1 SurveyA detail survey was carried out by LANDdata Surveys Pty Ltd in September 2011. All existing roadinfrastructure such as kerbs, signs, stormwater drains etc. were identified. In addition, all vergefeatures such as service covers, power poles, trees, footpaths etc. were located.8.1.2 Geotechnical investigationContaminationA geotechnical contamination investigation was completed by Douglas Partners Pty Ltd in April2011. Following this, a Remediation Action Plan (RAP) was prepared. A copy of this environmentaland geotechnical report is included in Appendix 3. Ground ConditionsA Geotechnical Investigation was undertaken by Douglas Partners to establish civil engineeringground conditions. This investigation, laboratory testing and associated report providedrecommendations on:Sub-surface conditions;Excavation conditions;The use of the site soils as fill and fill construction procedures;Pavement sub-grade conditions and design CBR values;Allowable bearing pressures and settlement performance;Geotechnical factors relevant to construction and site drainage, including batter slopes.8.1.3 Utilities investigationA Dial Before You Dig (DBYD) investigation has been carried out and existing services are detailedon the General Arrangement Plans (Drawings 110029/C1201 - 08). In addition, potholing serviceswere conducted in October 2012 to better understand the underground site constraints.8.2 Drainage8.2.1 Flood Study and Road DrainageIntroductionCampbell Section 5 is located in a stormwater catchment area of approximately 109ha as shown inFigure 8.1. The stormwater pipe infrastructure within the Campbell Section 5 site is the responsibilityof the NCA as it falls within NCA land, although upstream and downstream of the site TAMS isresponsible for the network.November 2012 Cardno 45
