York Civil was awarded the Civil Contractors Federation (SA) Earth Award for Excellence.

York Civil received the Category Four Award (for projects valued between $20 million and $75 million) for the Central Pipeline component of SA Water’s North South Interconnection System Project. The Earth Awards recognise excellence in environment, construction and project management.

The Central Pipeline Project was delivered as part of SA Water’s program to improve the quality of Adelaide’s water supply. Works comprised the design and construction of a 10km pipeline interconnecting the northern and southern water supply networks through highly populated residential and commercial suburbs, improving Adelaide’s water security, reliability and flexibility.

Mark Dedman, SA Water’s North South Interconnection System Project Director, said “York Civil responded proactively to construction constraints adapting their work methods in response to sensitive stakeholder and high traffic demand areas, for instance, conducting night-works along Walkerville Terrace so as to minimise disruption to business trading.”

Key challenges included the delivery of works in residential and commercial districts and the management of related delivery works such as environmental, traffic and safety management, site reinstatement and community engagement.

“In addition to effective health and safety performance throughout the package life cycle,” said Mark, “a high quality end product was delivered through robust quality systems and checks. Due to the critical nature of the infrastructure, York Civil had to perform under high pressure and within tight timelines in order to meet SA Water’s project requirements and program.”

York Civil’s Managing Director, Dominic Vieceli, congratulated the project teams’ effort on timely delivery of the works, and said that the award was a great outcome for all involved.

“Success was achieved through innovative thinking by the project team working at ground level,” said Dominic. “On North East Road, where daily traffic volumes reach 50,000 vehicles, the team developed a work method that saw the removal of the median strip to allow traffic to move relatively uninterrupted. This saved tremendous amounts of time compared to working only at night with restricted traffic flows.”

The project achieved outstanding safety performance, often achieved through innovative approaches. This included the use of American manufactured shoring equipment to better protect work crews operating in deep trenches. York Civil engaged geotechnical specialists and conducted testing to ensure the system was safe to use in the local conditions. The equipment was also tested against York Civil’s quality and safety systems.

As a result of these and other initiatives, the project completed 167,000 work hours with zero lost time injuries and zero medical treatment injuries, despite the challenges of multiple work crews and a workforce that peaked at 60.

The quality of the works was also recognised in the award. When the pipeline was hydro-tested nil leaks were identified requiring nil rework, which is generally unprecedented in a project of this size and complexity.
