17 Lot Residential Subdivision
Tullimbar NSW
APX Civil has been engaged to deliver one of the final residential land releases in the heart of Tullimbar, undertaking bulk earthworks and full civil infrastructure to create 17 large residential lots and a new internal road through the development.
STAGE 1
Site Establishment / Sediment Control / Site Office Setup
Client
Private
Region
South Coast
Status
Underway
The project commenced with full site establishment, including mobilisation of plant and equipment, installation of site compound facilities and temporary perimeter fencing.
Comprehensive survey control was undertaken to locate existing services, establish construction set-out and provide engineering control for all civil works. Traffic management plans were prepared and implemented, including council approvals, road occupancy requirements and ongoing traffic control measures to safely manage site access and construction activities throughout the project.
STAGE 2
Site Preparation & Environmental Controls
Initial site preparation included demolition of existing footpath sections and modification of kerbing to suit new access requirements.
Environmental protection measures were installed across the site, including silt fencing, inlet protection and construction of a sediment basin to manage runoff and erosion. Temporary construction access roads were also established to support efficient site operations.
STAGE 3
Bulk Earthworks & Site Regrading
Bulk earthworks operations included stripping and stockpiling topsoil for later reuse, followed by treatment and recompaction of existing uncontrolled fill to achieve design levels.
Imported fill was placed where required to raise site levels, with services trench material reused as engineered fill. The site was then trimmed and compacted to final subgrade levels before topsoil was re-spread across residential lots and verge areas to prepare for landscaping.
STAGE 4
Stormwater & Sewer Infrastructure
A comprehensive stormwater network was constructed to service the subdivision, including installation of PVC lot connections, reinforced concrete pipelines, precast pits and connections into existing infrastructure.
Drainage installed through existing roadways was reinstated to match surrounding conditions, with CCTV inspection completed to verify system integrity.
Sewer infrastructure works included trench excavation, installation of uPVC pipelines, property connections, maintenance structures and connection to existing manholes. All works were tested and completed in accordance with Sydney Water requirements.
STAGE 5
Roads, Pavements & Hardstand Construction
Civil works included construction of concrete footpaths, driveway crossovers and a reinforced concrete laneway slab complete with central dish drainage.
Subgrade preparation and base installation were completed beneath driveway and pavement areas, followed by installation of decorative brick paving to shared access areas. Additional works included construction of bin slabs and associated hardstand areas to support subdivision functionality.
STAGE 6
Services, Landscaping & Project Completion
Utility works included installation of potable water connections to all lots using underbore methods where required, along with electrical infrastructure, road crossings, street lighting provisions and NBN conduits and pits.
Final landscape works included installation of street trees, boundary and embankment planting, turfing of verge areas and hydromulching across residential lots. Following landscape establishment and maintenance, the project was delivered as a fully serviced residential subdivision ready for development.
