  5. 5. Currumbin RidgeLocation CurrumbinProject Engineer Bret ArthurSituationMedium density residential development (sixty nine individual units andduplex). The site is very steep with a history of slope instability.Construction of the access roads to service each unit required extensivecut and filling to achieve required grades. Access for construction was veryrestricted due to only one entry location and the steep narrow roadsproposed.SolutionThe roads were designed with cut and fill to minimise excessive earthworks.To stabilise the slopes, engineer designed masonry retaining walls withdeep piles were adopted. This enabled minimum excavation into theexisting slopes while maintaining a strong and durable retaining system.ResultsThe finished stage one area now enables a sealed all weather access to allareas of the site with stabilised batters for the construction of futuredwellings. The roadworks and stormwater drainage installed has helpedcontrol erosion on the site and managed the discharge of stormwater fromthe site in such a manner as to not effect downstream properties.WESTERA PARTNERS | PROJECTS | CIVIL AND ENVIRONMENTAL
  6. 6. St Paul de ChartresLocation Fedrick Street, Logan CityArchitect Brand + Slater ArchitectsProject Engineer Bret ArthurSituationSubstantial expansion of the existing aged care facility (fourty six singlestorey units) to the west of the existing site. The existing site is avaccant lot with only one exsiting building. Access is to be provided offthe existing road network to the west and linked to the existing agedcare facility. The site is considerably sloped across to an existing creek atthe south of the site.SolutionExtensive modelling of earthworks to create a road network andbuilding platform which can be used as pedestrian access for theoccupants. Stormwater drainage needed to be redirected and captured toensure no increase in flow was directed to the existing area’sstormwater system. A detention and water quality system needed to beinstalled that would cater not only for this stage but for future works aswell. To maximise site area for buildings an underground detention tankwas provided under the road network.ResultsConstruction for stage one is set to be finished in late 2011. Thedetention tank under the road has allowed for more site area to beavailable for buildings and for the dispersal of flows to the existing creekwithout excessive erosion. The site merges well into the existing roadnetwork internally and provides an easy acess for all residentialoccupants to walk to the main facilities building.WESTERA PARTNERS | PROJECTS | CIVIL AND ENVIRONMENTAL
  7. 7. Peterson RoadLocation CabooltureSupervising Partner Bret ArthurSituationResidential subdivision (one lot into twenty three). Existing single lotresidential alotment was to be subdivided up into twenty three seperateresidential alotments. External catchment from western park areafeeding into and through site. The existing road intersection on PetersonRoad needed to be modified to allow safe access to site. Existingstormwater and sewer mains in Peterson Road needed to be altered anddiverted to ensure adequate capacity still maintained to suit newdevelopment.SolutionLarge detection basin proposed in the south east corner of site to ensure noincrease in peak stormwater discharge flows. To maximise the useable sitearea for development the bio retention basin (needed for water quality) wasincorporated into the same footprint as the detention basin.ResultsA pleasant residential development which has maximised the saleable areaavailable while still maintaining aesthetic landscaping outlook for the ma-jority of the sites.WESTERA PARTNERS | PROJECTS | CIVIL AND ENVIRONMENTAL
  8. 8. Menser StreetLocation CalamvaleSupervising Partner Bret ArthurSituationHigh density residential townhouse development (two storey buildings).Existing site sloped to rear of allotment. Legal point of discharge for boththe sewer and stormwater was nominated at a location 180m to the westof the site, this would require the extension of the sewer and stormwaterthrough an existing council parkland. Removal of trees in the parklandwas not to occur and disturbance to tree root systems was to be minimal.SolutionTo ensure the construction of the sewer and stormwater did not adverse-ly effect the existing tree root system a combined shallow trench systemwas proposed with a tree arborist on site directing the construction. Thealignment of the sewer and stormwater drainage was altered severaltimes to ensure no damage to tree roots, where this was not possiblehorizontal directional drilling was to be undertaken.ResultsThe use of on site supervision and modern drilling practises has enabledthe construction of the stormwater and sewer systems to occur whereconventional construction would have resulted in the project notproceeding.WESTERA PARTNERS | PROJECTS | CIVIL AND ENVIRONMENTAL
  9. 9. Andergrove LakeLocation MackayArchitect Kevin Holt ConsultingSupervising Partner Bret Arthur & Sam IdeSituationThe Andergrove Lakes development involves six stages of development:- Standard residential lots - 86 in Stages 1-4, estimated 81 in Stage 6.- Medium density lots - 4 in Stage 1-4, numerous medium density villas andunits (110 estimated terrace houses equivalent) in Stage 6.- Commercial lots - 1 in Stage 1 (cable ski lake), 1 in Stage 4 (child care), 5 inStage 5, recreational lake operation and associated facilities in Stage 6.The site presents many challenges for the project including:- Difficult soil conditions such as marine clays and groundwater- Flooding by a complex mix of regional flooding and local overland flowfrom two separate catchments- Located within an area mapped as High Ecological Significance (HES) Wetlands- Receiving urban runoff from external catchments for maintainingproposed lake water levelsSolutionEarthworks were designed to maximise flood storage and minimiseonstriction of overland flow from external catchments. The materialbeneath the marine clays was tested and found suitable for use as fill forlots. Constructed wetlands and a natural waterway were designed to treatrunoff from the development and external catchments before discharginginto the proposed lake. Sewerage reticulation was designed to include agravity system, pump station and rising main.ResultsDesign and operational works approval for stages 1 to 5 are complete. Thecivil works for stages 1 to 3 have been tendered and is expected tocommence early 2012. The development has received positive mediaoverage and is expected to boost tourism for the Mackay region.WESTERA PARTNERS | PROJECTS | CIVIL AND ENVIRONMENTAL
