On the doorstep of the Swan Valley, RJV commenced work at Vale in mid-2012 and has since completed over 90 separate works contracts for Stockland, totalling in excess of $110M and providing housing lots for over 2,500 new homes in Aveley during this time. The main area of the works has been situated on farmland predominantly used for the training of racehorses. Prior to works commencement there was a significant demolition contract awarded to RJV for the demolition and disposal of structures, both above and below ground, including the cataloguing, removal, and disposal of large amounts of building materials including asbestos and other contaminants.

Subsoil conditions at Vale range from sand through to significant clay layers and occasional laterite. The management of acid sulphate soils and groundwater infiltration and acidity are daily tasks undertaken by RJV, along with the blending of site based topsoil with imported sand, providing a fill material that meets the strict permeability requirements of the development.

In May 2015, RJV commenced construction of the Ariella Private Estate in the suburb of Brabham, on the fringe of the Swan Valley. When complete, the 40 hectare development will comprise 500 residential lots developed in seven stages, and will include 11 hectares of community recreational facilities and a primary school. The development area includes a sensitive wetland and sits above an extremely high water table, with the treatment of acid sulphate soils, strategic dewatering and close monitoring and management of groundwater infiltration being part of the RJV daily operation.

The estate requires a large volume of imported fill sand to bring the site up to its design levels. This has required targeted planning and management in consultation with local authorities to ensure that existing residents and infrastructure are not adversely affected by high volumes of truck and machine movements occurring in the rapidly developing area of Brabham.

The development is adjacent to the Dampier to Bunbury Natural Gas Pipeline, one of WA’s most important pieces of energy infrastructure. Part of the works required the filling of parts of the PBNGP corridor to suit the estate levels, due to the sensitive nature of the works these earthworks are being completed by RJV in close consultation with DBP.

In August 2011, RJV commenced construction of the Whiteman Edge development in Henley Brook, 20km NE of Perth CBD (adjacent to Whiteman Park). When complete, the development will comprise over 1,500 residential lots and will include in excess of 22 hectares of community recreational facilities, a neighbourhood shopping centre and schools. The development is a joint venture between Stockland, Department of Housing, and Whiteman Edge Developments.

Construction at the site presented a number of environmental challenges for RJV, which prides itself on its commitment to environmental management. The development area is flanked by sensitive wetlands and sits above an extremely high water table. Treatment of acid sulphate soils, strategic dewatering and close monitoring and management of groundwater infiltration are part of the day-to-day operations being undertaken by RJV at the site.

Large volumes of imported local sand have been required to bring the site up to its design levels. This has required target planning and management in consultation with local authorities to ensure that existing residents and infrastructure are not adversely affected by high volumes of truck and machine movements.

To date, RJV has completed contracts in excess of $80m since commencement.

RJV commenced construction at Rosehill Waters in August 2016, starting with bulk earthworks on what was previously a public golf course. Initial works involved removal of nearly 15km of underground reticulation pipework, (much of it asbestos), together with remediation and backfill of existing ornamental lakes. Existing MRWA drainage installed through the golf course had to be realigned onto the new road layout via 1050mm diameter pipework at 7 metre depth. Given the close proximity of the Helena River strict sediment control measures were required to prevent turbidity in the Helena River.

Civil works followed the forward earthworks package, with Stage 1 incorporating approximately 170 lots and including 20,000m2 of road pavements, plus 400 metres of sewer slurry microtunnelling under existing roads and sensitive watercourses.

As at May 2018, RJV is currently constructing the second phase of earthworks and two further civils stages.

RJV"s association with PEET at Wellard commenced in early 2013 and to date, RJV has successfully completed $50m of Earthworks and Civil Works, which includes nearly 1,000 lots.

The Village at Wellard is Perth’s first greenfields purpose built transit orientated development, with the Wellard train station at the centre of the development. It will be ultimately home to some 7,000 residents. The development incorporates 2 wetlands and protected bushland which have been sensitively rehabilitated during development.

RJV commenced construction in March 2017 at Shenton Park Hospital, which is to be repurposed as a residential development by LandCorp. For the construction of the new development to take place the existing hospital needed to be cleared, demolished and rehabilitated to a state where civil works could be undertaken across the site. Given the age of the existing hospital, originally constructed in 1893, the demolition of the hospital contained various environmental risks which had to be dealt with in line with high level safety and environmental guidelines. These included asbestos, hydrocarbons, heavy metals, pesticides, buried services and potential groundwater contamination.

RJV worked in conjunction with licensed disposal contactors and offsite facilities to ensure the safe and responsible demolition of the site. Key works included:

• Removal and Management of Asbestos by accredited contractors from buildings and unexpected finds in excavations.
• Constant Asbestos fibre monitoring via automated monitoring stations around the perimeter of the site by a recognised Environmental consultant.
• Monitoring and testing of all demolished building footprints for contaminants such as hydrocarbons, heavy metals and pesticides.
• Removal of all contaminated material to licensed off-site disposal facility.
• Monthly groundwater monitoring to ensure groundwater contamination was not taking place throughout the works.
• Tracking of all exported material to ensure that all waste was accounted for.

RJV was able to successfully complete the demolition and remediation of the site. At the completion of works all materials were signed off as safely and responsibly disposed and the site was classified as clear for civil construction works to begin. All material was managed as per Green Start requirements with RJV achieving 99% recycling on this project.

Following completion of demolition and remediation RJV was awarded the Stage 1 Earthworks in November 2017 and Stage 1 Civils in January 2018, including an upgrade of the existing Selby / Nash Street intersection from traffic light controlled to a roundabout under live traffic conditions.
