Location CurrumbinProject Engineer Bret Arthur

SituationMedium density residential development (sixty nine individual units and duplex). The site is very steep with a history of slope instability. Construction of the access roads to service each unit required extensive cut and filling to achieve required grades. Access for construction was very restricted due to only one entry location and the steep narrow roads proposed.

SolutionThe roads were designed with cut and fill to minimise excessive earthworks. To stabilise the slopes, engineer designed masonry retaining walls with deep piles were adopted. This enabled minimum excavation into the existing slopes while maintaining a strong and durable retaining system.

ResultsThe finished stage one area now enables a sealed all weather access to all areas of the site with stabilised batters for the construction of future dwellings. The roadworks and stormwater drainage installed has helped control erosion on the site and managed the discharge of stormwater from the site in such a manner as to not effect downstream properties.

SituationSubstantial expansion of the existing aged care facility (fourty six single storey units) to the west of the existing site. The existing site is a vaccant lot with only one exsiting building. Access is to be provided off the existing road network to the west and linked to the existing aged care facility. The site is considerably sloped across to an existing creek at the south of the site.

SolutionExtensive modelling of earthworks to create a road network and building platform which can be used as pedestrian access for the occupants. Stormwater drainage needed to be redirected and captured to ensure no increase in flow was directed to the existing area’s stormwater system. A detention and water quality system needed to be installed that would cater not only for this stage but for future works as well. To maximise site area for buildings an underground detention tank was provided under the road network.

ResultsConstruction for stage one is set to be finished in late 2011. The detention tank under the road has allowed for more site area to be available for buildings and for the dispersal of flows to the existing creek without excessive erosion. The site merges well into the existing road network internally and provides an easy acess for all residential occupants to walk to the main facilities building.

SituationResidential subdivision (one lot into twenty three). Existing single lot residential alotment was to be subdivided up into twenty three seperate residential alotments. External catchment from western park area feeding into and through site. The existing road intersection on Peterson Road needed to be modified to allow safe access to site. Existing stormwater and sewer mains in Peterson Road needed to be altered and diverted to ensure adequate capacity still maintained to suit new development.

SolutionLarge detection basin proposed in the south east corner of site to ensure no increase in peak stormwater discharge flows. To maximise the useable site 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 saleable area available while still maintaining aesthetic landscaping outlook for the ma-jority of the sites.

SituationHigh density residential townhouse development (two storey buildings). Existing site sloped to rear of allotment. Legal point of discharge for both the sewer and stormwater was nominated at a location 180m to the west of the site, this would require the extension of the sewer and stormwater through an existing council parkland. Removal of trees in the parkland was 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 system was proposed with a tree arborist on site directing the construction. The alignment of the sewer and stormwater drainage was altered several times to ensure no damage to tree roots, where this was not possible horizontal directional drilling was to be undertaken.

ResultsThe use of on site supervision and modern drilling practises has enabled the construction of the stormwater and sewer systems to occur where conventional construction would have resulted in the project not proceeding.

SituationThe 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 and 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 in Stage 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 flow from two separate catchments- Located within an area mapped as High Ecological Significance (HES) Wetlands- Receiving urban runoff from external catchments for maintaining proposed lake water levels

SolutionEarthworks were designed to maximise flood storage and minimise onstriction of overland flow from external catchments. The material beneath the marine clays was tested and found suitable for use as fill for lots. Constructed wetlands and a natural waterway were designed to treat runoff from the development and external catchments before discharging into the proposed lake. Sewerage reticulation was designed to include a gravity system, pump station and rising main.

ResultsDesign and operational works approval for stages 1 to 5 are complete. The civil works for stages 1 to 3 have been tendered and is expected to commence early 2012. The development has received positive media overage and is expected to boost tourism for the Mackay region.

SituationThe Brown and Hurley families have been associated with John Westera since his days as Kyogle Shire Engineer back in the 1980s. Since this time and in particular more recently, Westera Partners have assisted in the national expansion plans of the Brown and Hurley Group. Part of this expansion was the design and construction of their Yatala branch including a sales yard, spare parts facility and workshop.

SolutionWestera Partners were commissioned by Brown and Hurley to undertake the Structural and Civil Engineering services for this project. We also assisted in construction tendering, builder selection and negotiations as well as construction administration and inspections. The Yatala project consisted of a modern, architecturally designed, purpose built precast tilt panel building with specialised finishes unique to the Brown and Hurley Group. Detailed consideration was given to the environmental sensitive elements of the project including the on site water usage and stormwater treatment. The practical, hands on nature of the client ensured that maximum efficiency was achieved for the end users.

ResultsWestera Partners have also assisted the Brown and Hurley group, in a similar role with their new branches in Toowoomba and Townsville. The Townsville branch was subject to the damaging winds of Cyclone Yasi and survived relatively unscathed. Westera Partners is proud to be associated with quality companies that share the same core values, such as the Brown and Hurley Group, whose motto is “People before Profit”.

Situation“Villa Serena” was commissioned by a respected local developer that specialises in aged care developments. He has been involved in a number of similar projects including “The Domain” in Ashmore and Helensvale Aged Care. Villa Serena was constructed in a number of stages, the most recent being the four storey multi level building located on the south-eastern side of the property. The site is located within the Robina Town Centre hub and close to the Pacific Highway, hospital, public transport and Skilled Park. Villa Serena is a boutique aged care community that focuses to maintain maximum independence, freedom and choices for its residents.

SolutionWestera Partners were commissioned to provide the Civil and Structural Engineering services for this development. The project architect, a long time associate of the client was also an aged care design specialist. The initial stage was a combination of single and two storey residential construction. Masonry retaining walls were detailed to provide the raised building platform when viewed from the road side. The final stage was a multi-level building with suspended concrete slabs supported by load-bearing masonry walls and concrete columns in the basement. Particular attention was given to smoke and fire separation compartments within the building with structural detaining to suit. The civil services for each stage had to be married together and incorporated into the existing infrastructure.

ResultsVilla Serena is a quality project and a testimony to the client, architect and builders ability to produce a quality development, on time and below budget. Since the completion of this project the client has successfully developed the five star residential aged care home located on Linfield drive, Helensvale.
