    • 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
    • St Paul de ChartresLocation Fedrick Street, Logan CityProject Engineer Samuel IdeSituationSubstantial 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
    • Peterson RoadLocation CabooltureProject engineer 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 ensureno increase in peak stormwater discharge flows. To maximise the useablesite area for development the bio retention basin (needed for water quality)was incorporated into the same footprint as the detention basin.ResultsA pleasant residential development which has maximised the saleablearea available while still maintaining aesthetic landscaping outlook for themajority of the sites.WESTERA PARTNERS | PROJECTS | CIVIL AND ENVIRONMENTAL
    • Menser StreetLocation CalamvaleProject engineer Samuel IdeSituationHigh 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 parkland wasnot to occur and disturbance to tree root systems was to be minimal.SolutionTo ensure the construction of the sewer and stormwater did not adverselyeffect the existing tree root system a combined shallow trench system wasproposed with a tree arborist on site directing the construction. Thealignment of the sewer and stormwater drainage was altered several timesto ensure no damage to tree roots, where this was not possible horizontaldirectional 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
    • Andergrove LakesLocation MackayArchitect Idea Architecture Pty LtdProject Engineer 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 villasand units (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 minimise constriction 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

    • Saltwater BargaraLocation Miller Street, BargaraProject Engineer Peter IdeSummary of the ProjectLocated on the ocean front of Bargara Beach, overlooking the Pacific Ocean.This residential development consists of three levels of luxury units with abasement floor, a concrete roof, swimming pool and landscaping features.SituationWestera Partners were engaged to carry out the civil and structuralengineering services for the project. There were a number of challenges toovercome, one challenge was that the neighbouring properties were locatedreasonably close to the proposed basement excavation and were in risk ofbeing undermined. Another challenge was the depth of the foundingboulder matrix below the basement excavation.SolutionWe were able to design and develop a construction methodology thateliminated the need of expensive sheet piling, but still provided adequatestabilisation to the excavation batters for the basement earthwork. Thefoundation design of the building chosen was a high level spread footingsystem in the low bearing capacity sands with localised compaction toreduce settlement. We were also able to be flexible with our designapproach when the client decided to reconfigure the load bearing walllocations in an effort to optimise the final unit spaces to suit purchasers.ResultThe construction was carried out without any incidents, in time and withinbudget. The development has won the UDIA QLD state presidents award forbest overall development in Queensland as well as the best small- medium density development awards.WESTERA PARTNERS | PROJECTS | COMMERCIAL, MULTI-RESIDENTIAL AND INDUSTRIAL
    • Freshwater PointLocation Broadbeach WatersProject Engineer Ross Keene & Clive CowdellSituationFreshwater point is positioned in the heart of Broadbeach andneighbours Jupiters Casino and The Gold Coast Convention Centre. Thedevelopment boasts approximately two hundred and sixty units intotal across three buildings from four to ten storeys in height. The resortsfacilities include outdoor heated pool, children’s wading pool, sauna, spa,steam room, gym, fishing jetty, café and meeting/function rooms.SolutionWestera Partners were engaged by the client to provide Civil and StructuralEngineering Services to this project. The buildings sit over a double heightbasement that pushes well into the surrounding water-table. Tensionground anchors were required to resist the large hydrostatic forcesassociated with this aspect. Precast walls and columns were adopted tosupport the reinforced concrete slabs to assist in reducing the very tighttime frame given to construct the building. These precast elements wereconstructed off site and were trucked and stock-piled on site ready to belifted into place after each deck pour. The modern architectural designrequired large cantilevered slab elements that can be viewed from allelevations.ResultsFreshwater point was delivered to the client on time and within budget.The construction techniques adopted by the builder were very efficientand resulted in the building being the “talk of the town” at the time, withreference to the construction speed.WESTERA PARTNERS | PROJECTS | COMMERCIAL, MULTI-RESIDENTIAL AND INDUSTRIAL
    • VIP PetfoodsLocation YatalaProject Engineer Clive CowdellSituationVIP Petfoods has become a household name and a world renowned QLDcompany specialising in fresh chilled pet food. This 7000m2 building is thecompanies head office located in Yatala. Its signature appearance can beeasily noticed when travelling along the Pacific Highway. The project wascompleted in two stages. Stage one was the two main factory buildings.Stage two was an extension to one of the existing buildings and a purposebuilt administration building.SolutionBeing a specialist food preparation building, Westera Partners workedclosely with the architect and builder to maximise the efficiency of thedesign with particular attention to hygiene. The pet food preparationbuilding is a portal frame structure with the portal columns located on theoutside of the building. This technique enabled the insulation wall panelsto continuously run around the perimeter forming both the internal andexternal wall structure. The ceiling panels were supported by the concealedroof steelwork. The ground floor slabs were post-tensioned to limit thefloor jointing within the building, thus improving the hygiene component.ResultsVIP Petfoods is a real local success storey and the company continues togrow worldwide. Westera Partners is proud to be associated with this clientand look forward to continued work through expansion in the future.WESTERA PARTNERS | PROJECTS | COMMERCIAL, MULTI-RESIDENTIAL AND INDUSTRIAL
    • Kula Beach HomesLocation CoolumProject Engineer Joshua NealeSituationThe Kula Beach homes are situated on the Sunshine Coast nature reservesand within a close walk of the beach. The project consists of sixty twounique architecturally designed homes created by four of Australiasleading architect firms. The homes which are two and three storeys highwere required by the developer to be economically constructed withoutcompromising the designers creative intent.SolutionWestera Partners were given the responsibilty of creating a uniform,efficient and affordable construction methodology for all four architectsdifferent design variations. We were able to simplify complex problems andexplore extensive options to satisfy the builder, architects and developer.ResultsThe completed homes have proven to be extremely popular in the marketwith many industry awards already been won. The ability of WesteraPartners to communicate with so many different parties on this projectand deliver a simple and unified solution has been a contributing factor inthe projects success.WESTERA PARTNERS | PROJECTS | COMMERCIAL, MULTI-RESIDENTIAL AND INDUSTRIAL
    • HarmonyLocation Runaway BayProject Engineer Clive CowdellSituationHarmony is a unique apartment development incorporating the fine art ofFeng Shui. The project comprised of six seperate buildings from betweenthree and eight stories in height built entirely over an undergroundbasement. The buildings size and orientation were paramount to thedesired theme. The development incorporates a common central courtyardwith pool, fire pit, private niches and community spaces surrounded byplanting which includes a number of original mature trees retained on thesite. A central water feature snakes its way through the central court-yardnaturally dividing the different spaces.SolutionWestera Partners were commissioned by the client to undertake Civil andStructural services on this project. The sites stormwater bio-retentionsystem was cleverly incorporated into the landscaping scheme. Thebuildings foundation raft slab and podium slab were post-tensioned dueto the large basement spans and carrying load pattern above the podiumdeck. The roof slabs were also stressed to help ensure water-tightness.Generally the typical floors were reinforced concrete supported on block-work and cast insitu concrete walls/columns. The site had a high watertable so particular attention was given to de-watering during the basementexcavation and construction of the buildings to ensure this would not be anissue for the structure.ResultsHarmony is a unique development with a lot of special featuresincorporated, that may not be necessarily visible and therefore appreciatedby the buildings occupants. The developer has been meticulous in followinghis desired theme throughout and has worked very closely with theconsultants and builder to create a product that he is particularly proud of.WESTERA PARTNERS | PROJECTS | COMMERCIAL, MULTI-RESIDENTIAL AND INDUSTRIAL
    • Audi Centre Gold CoastLocation Southport, Gold CoastProject Engineer Ross KeeneSituationFollowing continued strong growth in Audi car sales throughout Australia,Gold Coast Audi franchisee the Frizelle Group embarked on this impressive$11 million development. The development comprises a basement carparkand car storage area, showroom, administration areas and 23 high-techservice bays. The architectural design and detailing of the building wasrequired to conform to Audi’s Showroom Concept, which is used around theworld to bring a distinct identity to their dealerships. This includes a curvedfloor plan with raking columns and walls to divide the customer zone fromthe car presentation zone.SolutionThe showroom area, with its curved gallery level and raking columnsoffered the most challenging aspect to this project. The curve and rake tothe columns resulted in the office level, some 8m above the showroomfloor, having large spans of up to 24m. A structural steel frame comprisingraking and vertical columns, and deep steel plate I beams, was designed tosupport precast pre-tensioned concrete floor planks. This structural systemminimised the need for high formwork scaffolding. Care was requiredduring the design, detailing and construction to maintain the stability ofthe steel frame until the perimeter blockwork bracing walls and floors wereconstructed.ResultsThe completed building offers Audi customers a sophisticated openatmosphere to compliment the premium quality of the vehicles on display.They can even enjoy a coffee in the cafeteria overlooking the showroomfloor.WESTERA PARTNERS | PROJECTS | COMMERCIAL, MULTI-RESIDENTIAL AND INDUSTRIAL
    • Tweed Valley RespiteLocation KingscliffProject Engineer Joshua Neale & Daniel ChristieSituationThe project is a relocatable modular structure built and transported tosite, then craned into position. The site had limited access which requiredlifting the structure over the existing obstacles.SolutionThe design incorporated a welded steel chassis which can be seen in thephotos to act as the rigid support frame during the lifting process. Oncethe building has been craned into position on the steel posts this framethen becomes the floor structure. The building is supported on isolatedpier footings.ResultsThe structure is currently in operation and functioning effectively in thecommunity.“ WESTERA PARTNERS PROMPT RESPONSES TOQUERIES & ENGINEERING DESIGN SOLUTIONS HASFACILITTED A SMOOTH WORKFLOWJOHN RISSMAN - ARCHITECT ”WESTERA PARTNERS | PROJECTS | COMMERCIAL, MULTI-RESIDENTIAL AND INDUSTRIAL

    • Hungerford LaneLocation KingscliffSupervising Partner Joshua NealeProject Engineer Dan ChristieSituationThe house is located on a sloping site and was met with extensive rockexcavation. The design had to take into consideration the build over sewerline which is located under a large section of the residence. The site is alsoexposed to high wind speeds and the architectural layout had minimalopportunities for bracing due to the open design and Bi-fold doors. Theopen design also meant that there where large cantilevering sections withrestricted locations for support columns to give the desired open design.SolutionThe design outcome was achieved by closely working with the Architect andbuilder. The design incorporated raft slab on ground and pier footings tospan the structure over the sewer line. The large cantilever members wereachieved by the use of steel beams and the structure was braced with a mixof conventional ply bracing and steel work.ResultsThe house is a standout residence in the area. With an incredible opencoastal feel with un-interrupted views when opened up.WESTERA PARTNERS | PROJECTS | RESIDENTIAL
    • Small StreetLocation NewsteadProject Engineer Joshua NealeSituationThe house is located on a very small site being only 230 square meters.The site also required potentially complex foundations due to theneighbouring property being built to the boundary. Bracing of thestructure was challenging as a result of the architectural form and theneed to maximise views.SolutionWe were able to design the structure to resist bracing loads by theintroduction of a simple steelwork portal frame and the introduction ofblockwork nibs which added minimal costs to construction. We alsoadopted a hit and miss approach to the foundation system to avoidundermining or underpinning of the adjacent residence which savedsignificant costs during construction.ResultsAn award winning architectural home that is intricate and yet structurallyefficient. The attention to structural detail is evident in the constructionsimplicity and clean form.“ BEING A VERY SMALL AND TIGHT SIGHT, THEENGINEERING WAS TO BE SMART, SIMPLE AND EASYTO ERRECT.SHAWN GODWIN - BASE ARCHITECTURE ”WESTERA PARTNERS | PROJECTS | RESIDENTIAL
    • Cylinders DriveLocation Salt VillageSupervising Partner Joshua NealeSituationThe house is located in a high wind coastal region and is susceptible toharsh environmental factors such as salt air, thermal fluctuations and largerainfall events. The subject site is also located in a newly developedsubdivision that experienced considerable filling to achieve design levels.SolutionThe project was designed to resist high wind forces by the introduction ofa suspended slab and masonry walls to assist in diaphragm action to theexposed rear of the house, thus avoiding unnecessary and bulky steelwork.The foundation system adopted was a raft slab that spread the mass ofthe house over the majority of the site to minimise differential settlement.ResultsThe completed house is a standout along the esplanade at salt village andalways grabs the attention of visitors. The builder, Steve Kerr from SteveKerr Homes, has won several awards for his teams extraordinaryworkmanship and attention to detail. The client has been very pleased withthe final outcome.“ The signficant house structure was efficientlydeveloped by the Westera Team and resulted in a refinedcomposition.Chris Lillis - Crisilis Architecture ”WESTERA PARTNERS | PROJECTS | RESIDENTIAL
    • Lota HouseProject Lota HouseProject engineers Peter Ide & Matthew GibbsSituationThe residence is located on a triangular block near the esplanade frontingRaby Bay. The design had to meet client expectations of high ceilings andopen plan living whilst the structure had to withstand the high wind loadscaused by the exposure to Raby Bay.SolutionWestera Partners worked closely with the architect to design variouscarefully detailed timber and steel bracing elements which ensured theopen planned concept was achieved whilst keeping to the clients budgetrequirements.ResultsThe finished constructed form has effectively delivered to the clients abeautiful conducive environment for producing their own creative work.The collaboration between the architect, builder and Westera Partners hasmanaged to ensure the restrictive site has been optimised to its fullpotential.WESTERA PARTNERS | PROJECTS | RESIDENTIAL
    • Hedges AvenueProject Hedges AvenueLocation Mermaid BeachProject Engineer Anthony HockingsSituationThis house was constructed over four sites on “millionaire’s row”, HedgesAvenue, Mermaid Beach. The two storey residence is built entirely over abasement that features large column free space for car storage, a featurewine cellar crafted by a specialist artist to create a vintage feel, largecinema room, gym and plant rooms. The architectural design maximisedthe beachfront views on each level and special consideration was given tothe large entertaining areas overlooking the beach, pool and tennis court.The two large columns facing the beachfront represent goal postsreminding the original owner of his successful professional AFL career.SolutionWe designed the house using a number of specialist techniques. Generallythe floor slabs were reinforced concrete construction, however the thirteenmetre free span over the carpark required a post-tensioned slab. Theexternal walls were either block work or cast insitu concrete for durabilityand longevity. The building is situated within the council scour zone andtherefore the foundations are supported on deep piles. Ground retentionsheet piling was adopted on the southern boundary to protect theneighbouring property. Condition reports were completed on eachneighbouring structure prior to construction.ResultsThis home is regarded one of the most valuable properties on the GoldCoast. Its short history already boasts many interesting stories that stretchfar and wide. Its presence commands attention from passes buy, anunforgettable image spread across one of the most beautiful beaches inthe world.WESTERA PARTNERS | PROJECTS | RESIDENTIAL
