The Waikawa Road Shoulder Upgrade project involved earthworks, installation of services (mainly stormwater), the preparation and pouring of concrete kerb and footpaths and roading with chip seal.
Culverting 45m of open stormwater drain and 65m of open watercourse including connection to existing outlet pipes, inlets and manholes. This involved over 100m of stormwater pipe installs most of which was 1050 pipes, 2 deep 2000 internal square manholes, 1 1050 grated headwall with rip rap all right beside a busy road, under powerlines and in an existing services corridor. The works also included site clearance, protection of existing services, erosion and sediment controls, extensive earthworks and structural filling, temporary works (shoring), hiab support of power poles, very large custom manholes crane lifted in in segments, all new kerb and footpath, full lane width road reconstruction and surfacing, stakeholder management and safety (private land access and a primary school next door), traffic management of the busy Waikawa Road, all QA and surveying.
The project also involved the installation of two large square concrete manholes. These manholes had to be precast in sections and then lifted onto site with a crane. This was all done while working under high voltage power cables. Overall, the project was completed to a very high standard with lots of good feedback from the local community.
