Torrens Street and Crozier Road Roundabout Construction

Client: Department for Infrastructure and Transport
Construction Period:
 6 Months

Project Scope: 
Torrens Street is a key arterial road through the Victor Harbor town centre providing an important link in the regional road network carrying the majority of traffic. Torrens Street is under the care, control, and management of DPTI between Victoria Street and Hindmarsh Road. Torrens Street intersects with a number of other local roads under the care, control, and management of the City of Victor Harbour Council, including Crozier Road.

A road safety audit identified numerous safety concerns with the 4-way intersection including the potential for right angle collisions and poor connectivity for pedestrians. The state government consequently committed to installing a roundabout as part of the Safe Country Roads program.

Camco were engaged to construct this project which included significant traffic management challenges as the intersection needed to remain open to contra flow throughout the works. The project scope included widening of the existing radius kerbs, public lighting upgrade, construction of new deeplift asphalt pavement, installation of new concrete annulus and splitter islands, linemarking and footpath remediation.

Innovation: Traffic management and the safe, fluid movement of traffic through the site was a key consideration in the methodology, whilst traditional methods of stop-slow and portable traffic lights were utilised, more innovative approaches were also adopted. The use of a “temporary roundabout” from the project outset not only increased productivity it also provided a safer site for both workers and road users alike.


West Thebarton and Phillips Street, Road Reconstruction

Client: City of West Torrens
Construction Period:
 47 Weeks

Project Scope:
With such large works having to be undertaken, this project was broken down into two stages. The first stage took place on West Thebarton Road, Thebarton with the upgrade of the road and associated streetscape works. Stage 2 was on Phillips Street taking the upgrade from South Road to Port Road.

The project scope included detailed service investigation and survey, environmental soil classification, installation of 1500m of directional drilled common service trench, kerb removal and replacement, adjustment of existing service pits, footpath reconstruction with new block paving, exposed aggregate concrete driveways, stormwater works (including construction of approximately 500m of stormwater drainage works, up to 4.5m deep), deep lift pavement reconstruction, block paved side street intersections, irrigation and electrical design and installation, soft landscape works and ancillary landscape structures.

Problem Solving: Service locating and potholing prior to construction of new stormwater allowed us to redesign the stormwater to optimise trench excavation and identify service clashes not picked up in original design. This significantly reduced construction cost, unexpected delays due to service clashes and time to install.

Work, Health and Safety:Two-way and pedestrian traffic was successfully managed with site personnel and traffic controllers while works onsite were being undertaken.

Local Resources: This project utilised the services of two local subcontractors, Space Landscape Construction and Consolidated Landscape Services.


Cambridge Terrace Roundabout Upgrade, Unley

Client: City of Unley
Construction Period:
 8 Weeks

Project Scope: 
The scope of this project involved the reconstruction of two roundabouts along Cambridge Terrace to increase safety for cyclists and pedestrians. DDA compliant kerb ramps and openings in the kerb protuberances and splitter islands were also included to provide increased safety for pedestrians. Both Wattle St and Fisher St are busy shortcut routes through the Malvern area. Maintaining traffic flow through the intersections whilst completing the works was a critical criteria for the client. By using temporary traffic signals, we were able to achieve this, and open the intersections to two-way traffic out of hours to avoid any further risks.

Innovation: By utilising pavement profiling techniques and adding additional resources during critical tasks, we were able to optimize the program and complete works within tight timeframes resulting in less disruptions to normal traffic flows.
