ROAD & PAVEMENT CONSTRUCTION

 

Lower Hermitage - Road Safety Upgrade Project

Client: Adelaide Hills Council
Construction Period:
 15 Weeks
Value:
$750,000

Project Scope:
The construction brief for this project set out to complete the widening of Lower Hermitage Road to increase the carriage width to 2 lanes. Detailed project scope included bulk excavation of the existing verge batter, earthworks to construct a new lane on the inside of the existing carriageway, granular pavement construction, spray seal surfacing, linemarking and fencing. The intersection at Miller Road was also widened with drainage extensions and new headwalls placed.

Innovation: The volume of material to be removed and height of the cut batters were very difficult to construct. This was achieved by using very experienced operators along with dual excavators to safely carry out the works on time and on budget. The volume of material to be removed and height of the cut batters were very difficult to construct.

The works fronted existing properties, where stock fencing required reinstatement on new boundary lines. Due to the height and access difficulties, this was undertaken by hand at no additional cost to the client.

 

Longwood Road, Heathfield - Sports Court Renewal

Client: Adelaide Hills Council
Construction Period:
 11 Weeks
Value:
$315,000

Project Scope:
Project scope included demolition and removal of existing fencing, retaining walls, court surfaces and sporting equipment. The new fenceline was altered, and a concrete plinth installed beneath the bottom rail to assist in drainage and prevent scouring of the court edge. A feature element of design was the new concrete stairs and being able to move patrons through the split level courts with ease. New asphalt court surface was placed and acrylic surfacing laid to national standards. Completion activities saw new linemarking and sporting equipment provided.

Innovation: Camco (SA) worked closely with our client to ensure the design brief was delivered to expectations, with little official project design documentation. This was achieved to high standard with additional expense the contract, however saved on the need for Council to engage and external consultant.Camco (SA) worked closely with our client to ensure the design brief was delivered to expectations, with little official project design documentation.

Torrens Street and Crozier Road Roundabout Construction

Client: Department for Infrastructure and Transport
Construction Period:
 6 Months
Value:
$1,650,000

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
Value:
$5,700,000

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.

 

Rutland Avenue - Road Resurfacing and Raingardens 

Client: City of West Torrens
Construction Period: 16 Weeks
Value: $1,150,000

Project Scope: Road infrastructure and stormwater upgrade of Rutland Ave between Henley Beach Road and Sir Donald Bradman Drive. The project scope consisted of re-kerbing of approximately 2,000lm, construction of eight new paved speed humps and concrete approaches, 15 raingardens of various shape and design, including irrigation and road resurfacing.

Problem Solving: Design optimisation for the speed humps occurred, this was due to speed of construction and longevity of the asset. As a result of the programme was accelerated by four weeks and access for through traffic was maintained at all times.

 

Cambridge Terrace Roundabout Upgrade, Unley

Client: City of Unley
Construction Period:
 8 Weeks
Value:
$330,000

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.

Onkaparinga Road, Woodside - Supermarket Access Road

Client: Cambridge Group SA
Construction Period: 5 Weeks
Value: $310,000

Project Scope: The project consisted of constructing a two new parallel parking bays off Onkaparinga Valley Road at Woodside, adjacent the new shopping centre that had been recently constructed. The main road was realigned to accommodate a right turn lane, which involved reconstructing the existing parking bays to a heavy duty trafficable pavement. New lighting, linemarking and pedestrian bollards were also installed as part of the scope of works.

Problem Solving: Upon commencement of excavation works it became apparent the watermain had insufficient pipe cover to be able to construct the design as documented. Working closely with the client, design team and SA Water representatives an alternative pavement configuration was designed and constructed to alleviate SA Water concerns with old and fragile infrastructure.Upon commencement of excavation works it became apparent the watermain had insufficient pipe cover to be able to construct the design as documented.

The newly constructed driveway to the shopping centre was slightly out of alignment with the construction documentation. A simple redesign allowed the new kerb line to match neatly to the driveway, which in turn meant works proceeded without having to close the carpark entrance for an extended period.
