Robin Murphy’s first major project began in the Western Highland Province of Papua New Guinea (PNG). A dense and lush valley in the central mainland at an elevation of more than 1500 metres.
It was Robin’s first working expedition outside Australia. He had successfully been awarded the design and construction of four permanent steel and concrete bridges. From design, employment, purchasing and communications to logistics, plant manoeuvring and various other roles, Robin was responsible for the entirety of the project. 50 years since its completion, experiencing harsh and devastating natural disasters, the Nebliyer Bridge still stands and is in complete operation.
In 1978, Robin Murphy moved his construction and engineering company from Tasmania to Queensland and founded Construct the precursor to Canstruct. After six years of operations, Construct was purchased by Danish company Christiani & Nielsen (C&N), who led Construct to many significant projects throughout Australia. During this time, Robin remained integral in C&N’s operations as Managing Director.
After almost a decade, Robin repurchased all company shares, goodwill and reputation of Construct and 1991, Robin would go on to change the name of the company to Christiani And Nielsen Construction transforming Construct to Canstruct.
Located at the northernmost region of the Great Barrier Reef, three kilometres east of the Papua New Guinean border and 40 kilometres west of Murray Island, Canstruct was contracted to install a navigation tower. The travel time to this remote location spanned 10 days via tug-boat. Upon arrival, a 150-tonne platform was secured together with the pre-fabricated tower components. Two decades on, this 33-metre structure still stands, providing critical navigation services.
A contract to perform remediation works on the Brisbane Story Bridge. The Story Bridge was showing significant signs of structural stress and in some part’s major failure. The works involved the instalment of newly reinforced concrete decking to replace the concrete cancer of the existing locations. This included the footpath along the Bridge and the concrete construction joints in the main road deck.
The steel work of the bridge’s infrastructure was severely degraded. Thousands of heavily corroded bolts and nuts throughout the structure together with corroded girders were replaced. Approximately 2000 new gal steel stairs and walkways were installed to replace the existing timber walkways from the original 1930’s construction.
In partnership with Worley Parsons, Ostwald Bros and Department of Main Roads Canstruct designed, widened and rehabilitated a large section of the Dawson Highway, including the construction of multiple bridges. The 91-kilometre project between Calliope and Banana in Central Queensland, main project objective was to increase the width of the carriageway, improve road roughness and pavement strength along the Dawson Highway.
Canstruct provided early constructability advice during the design phase, constructed all bridges, the camp and other structural works. The ARRP CQ Alliance project reached practical completion in December 2007, six months ahead of schedule with a solution that achieved savings in of 10% for the client.
Canstruct was responsible for the construction of accommodation facilities and associated amenities for the Nauru Infrastructure Project. This included a hospital reverse osmosis and desalination plants, wastewater treatment plant, communication towers for the reticulation of data and hand-held duplex radio, a school and other community and ancillary facilities on Island.
Canstruct was awarded a lump sum contract to design and construct four new bridges and approach roadworks along the Kokoda Highway in the Oro Province of Papua New Guinea. The new bridges were to replace the existing bridges destroyed by Cyclone Guba in 2007. The new bridges provide permanent crossings over four separate rivers in the Oro Province.
All bridges have various spans with total lengths of:
Kumusi River - 285m, Girua River - 150m, Ambogo River - 100m and Eroro Bridge - 66m.
This major project was delivered for the PNG Department of Works two months ahead of the Contract PC date and under the client’s budget. Surplus project funds were used to upgrade other high priority crossings within the province, providing greater flood immunity and consistent local accesses.
An Engineering Procurement Construction Management (EPCM) contract to design, install and commission an undersea discharge pipeline. The scope of the project included the replacement of 3.6 kilometre of 800mm diameter ocean outfall pipeline which had failed in waters up to 60m deep off the coast of New Caledonia.
Instead of performing all pipe fabrication and pipe lay activities offshore on a high-tech vessel, Canstruct’s proposal was to separate these activities between onshore and offshore. Pipe installation and connection works were high-risk activities and were conducted in an open sea environment from numerous vessel types. The high value of the project works was required to be completed within a particularly restricted timeframe to enable construction outside of the cyclone and wet season.
Canstruct celebrates 50 years of delivering construction and infrastructure projects throughout Australia and the South Pacific. From the beginning, we have made a conscious effort to solve complex problems in remote areas to create impactful and dynamic solutions.
Awarded by the Australian Department of Home Affairs, we provide facilities management services to the Department and the Nauruan communities as part of Nauru Garrison Support Services. Our scope involves schedule maintenance, reactive maintenance and breakdown services on over 22,000 assets, emergency management, logistics, catering, pest, vermin and vector control, accommodation management and transport.
In collaboration with International SOS, Canstruct designed and manufactured ten Mobile Air Pressure Units (MAPU) to provide a medical unit capable of being deployed to remote locations. International SOS provided specialist medical advice during the design phase ensuring the MAPU were fit-for-purpose for treating or the isolation of COVID-19 patients. These units have been deployed to remote medical facilities both domestically and internationally to assist during the current pandemic.
The 2019 Australian bushfires devastated communities and businesses throughout Australia. In the wake of this significant event, Canstruct provided advisory and pro bono assistance to fire affected communities and small businesses in addition to donating to various causes to support those affected.
