Description of project:
The Villawood Immigration Detention Facility Redevelopment project involves the $180 million expansion of the existing detention centre. Rainbow is the Major
Works Civil Contractor for the project and has been on site since May 2011 successfully completing the Early Works package in September 2012 and Stage 1 works in December 2013 and now undertaking Stage 2A works.
Early Works largely involved the remediation of over 50,000m2 of asbestos contaminated soils, including the excavation and offsite disposal of approximately 2,000 tonnes of friable asbestos soils and the on-site remediation of approximately 10,000 tonnes of bonded asbestos soils for validation and re- use across the site. Early works also involved the bulk and detailed earthworks for future building pads, roads and car parks, construction of access ring roads around the development, demolition works and the relocation of multiple heritage structures.
Stage 1 Works commenced in May 2012 and largely involves the construction of over 20,000m2 of heavy duty roads and car parks to service the new detention centre. Rainbow’s scope of works includes:
- Bulk excavation and road box-out
- In-situ cement stabilisation of over 20,000m2 of subgrade to ensure it is suitable for a range of light and heavy traffic during its occupation
- Flexible pavement construction to AUS-SPEC standards
- Rigid pavement construction
- The construction of over 1.7km of new stormwater systems and over 6km of new subsoil drainage, including the construction of over 70 trafficable in-situ concrete pits ranging in size from 900x600mm to 3000 x 3000mm integrated within the pavement construction
- The construction of a large onsite detention basin to capture the entire stormwater system of the site including the construction of three headwalls, a major outlet discharge structure
- Construction of earth-retaining structures including both core filled concrete block walls and keystone block walls
- Concrete and paving works including footpaths, pram ramps, stairs and off-form concrete walls
- Streetscape works including the installation of over 35 custom seats and 7 benches
- Complex design management and consultant coordination
- Complete quality, safety and environmental management
- Traffic management
Stage 2A works commenced in May 2014 after successfully completing Early Works and Stage 1 works over the past 3 years. Stage 2A works involves similar civil works completed in Stage 1 above, also including bulk excavation and on- site management of over 25,000m3 of spoil, the construction of over 1000m of flexible pavement roads, stormwater construction, earth-retaining structures and streetscape works.
