Project Scope: Upgrade of an existing failed in-situ concrete box culvert base slab adjacent Main North Road Munno Para. The project scope includes the excavation and stockpiling of an existing noise mound (approximately 4m high), removal and storage of the existing 3m x 900mm high box culvert crowns, demolition of the failed base slab, preparation and construction of the new in-situ structural base slab, remediation of all culverts and replacement of the existing culverts that were beyond repair, backfilling and reinstatement of the existing noise mound and various small drainage modifications. 

Innovation: Whilst working onsite it was identified that there were some failures further upstream meaning that water was leaching into the in situ soil and bypassing the culverts. Council requested that this was repaired. The repair methodology was then developed in conjunction with the supplier to ensure the longevity of the repair, it used various highly specialised crack patching materials that were able to be applied in damp and underwater conditions.
Problem Solving: Once the culverts were exposed it was identified that a number of culverts were beyond being salvaged. Camco demobilised at no extra cost to the client whilst awaiting the manufacture of the additional culverts.
Work, Health and Safety: Working in an active watercourse, meant that it was imperative to maintain a high standard of environmental management. A low flow pump set up was established in order to reduce the flows through the site and sedimentation basins as well as haybale traps were constructed in the water course to reduce sediment levels.

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.

Innovation and Value Add: 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.

Client: SA Water
Construction Period: 8 Weeks
Value: $880,000

Project Scope: In order to facilitate the construction of the Gawler East Link Road, a new OD711 MSCL water main at the intersection of Potts Rd/ Para Rd/ Main North Rd intersection was laid. This included a 15m DN250 DICL branch on Main North Road, and link-in to the existing network at locations outside the scope of the proposed DPTI intersection, to prevent digging up new road for future connections.

Innovation and Value Add: Day works were altered to night works as requested by SA Water, to alleviate resident complaints.In order to maintain as many full lengths of pipes as possible (due to various services making it impossible to maintain full lengths), an innovative solution for pipe installation was developed across Main North Road. 

Client: City of West Torrens
Construction Period: 16 Weeks
Value: $630,000

Project Scope: This project involved the extension of an existing stormwater pump station discharging into the Sturt Creek channel at Shannon Avenue Glenelg North. The scope included the supply and installation of a new pump chamber, two new valve chambers (retro-fit one), installation of new outlet pipework, switchboard upgrade, mechanical fit out and connection to existing stormwater network.

Innovation and Value Add: The build required the excavation to be 5m deep in ground water with one side of the opening being against the existing pump station meaning the use of traditional shoring would result in a clash with the existing stormwater pipe. Camco was able to redesign the footprint to install the lower increments of the new pump station first and back fill with CLSM (controlled low “concrete” strength material), allowing the connecting pipe to be excavated safely between the two pump stations.
