This redevelopment located in Piara Waters consists of a 28 hectare site Titles Newhaven Grove. It is bound by Nicholson Road to the west, Piara Drive to the south and existing subdivisions to the north and west.
The development of approximately 500 lots and a central Public Open Space was carried out in 17 stages.
The bulk earthworks design requirement was to achieve as close as practicable to a balanced cut to fill whilst interfacing with adjacent properties. Given the shallow ground water levels of the site, considerable amount of fill material was required to address drainage requirements.
One of the key requirements of the UWMP supplied by the hydrologist was to protect the central wetland and utilise the existing natural stream as the main drainage outlet for the 17 stages. An extensive amount on liaison was carried out by the consultant team with the City of Armadale to ensure design and approval phases were promptly closed out, whilst addressing the UWMP requirements. JDSi successfully designed the pit and pipe network system for each stage to outlet into this central catchment.
During construction, JDSi oversaw the swale-built form and managed the interfaces between civil contractor and landscape architect.
JDSi successfully managed the design, approval and construction phases for the Water Corporation sewer line that was built through ‘directional drilling’ below recently completed civil stages. This sewer spanned through the entire estate and had a number of complex interfaces that required efficient planning and coordination.
JDSi integrated multiple work packages concurrently and successfully delivered the design and construction of several stages. In one instance, JDSi was managing 10 contracts out of the 17 civil stages. The relationship between the Client, Local Authority and Contractor was highly professional which facilitated the on time delivery of this 500 lot estate.
