We have delivered more than 350 projects since 2010

We audited the existing haul roads of a key Newmont site to determine compliance with design specifications, with a focus on grades and bund geometry. In addition, to ensure the compliance of current networks, Newmont engaged CEA to complete detailed audits of the wider road network. Our expertise in haul roads enabled our team to identify areas of concern and design rational solutions.

CEA delivered the civil works design for KGL’s Jervois project. Our scope included access roads, pads, drainage, minor dams, and refuelling and washing facilities – made possible because we provide a full design service using experienced engineers. As a result, the project’s civil infrastructure was functional and achieved the capex-to-opex balance sought by the project manager.

To best manage heavy and light vehicle interfaces, CEA was retained to design the mine’s go-line. We developed the owner’s concept into the final design, removing HV/LV interfaces, integrating smart drainage and accommodating extra parking for operations. Output included a comprehensive model that could be uploaded to the on-site fleet, allowing works to start immediately.

Although CEA regularly supports tier one contractors and mine operations, we are equally committed to boutique companies. Neill Earthmoving has repeatedly engaged CEA over many years to assist with tenders, minor designs, project management and quality assurance. Our real-world experience drives logical construction programs and costings for rural and urban projects.

Our team offers proven expertise in remote area works – and the Harmony core shed is an excellent example. The location meant the design had to be compliant and offer high-grade constructability using available materials. This leveraged our team’s true design-and-construct capability. CEA worked with the contractor to understand their constraints and developed a design that successfully met strict requirements.

Seymour Whyte engaged CEA as the subject matter expert for the tender’s bulk earthworks and haul roads. We embedded an engineer in the contractor’s team to provide concept designs and construction methodologies with full appreciation of how they integrated with the wider solution. CEA identified real savings in areas such as stockpile design, and designed haul roads to suit in parallel.

CEA designed the heavy vehicle (ie ultra-class haulers) and light vehicle roads for Cadia. The designs were completed using state-of-the-art civil engineering software by a team that offers a deep understanding of haul road design and construction. The design methods we used allowed all sighting tests to be safely performed prior to any works commencing in the field.
 

Our team was selected to develop the spoil management strategy for the Lake MacDonald project. CEA designed all stockpiles, pads and drainage infrastructure from concept design through to issued-for-construction design. Our team’s in-house RPEQ and CPEng-certified engineers offer the skills and expertise needed to complete niche civil engineering designs with a focus on value.
 

CEA has completed the mass haul for one of Australia’s largest windfarm projects. Using industry-leading software, our team produced an accurate mass haul including options such as hauling across property boundaries, and rejecting hauls on public roads. Flexible outputs allowed the project team to readily modify their designs and develop a defendable cost model.
 

Many Inland Rail projects have benefited from mass haul analyses completed by CEA. Since 2018, we have worked with tendering and design teams on some of the largest and most complex mass hauls in the country. Our in-house processes ensure that our calculations are accurate and repeatable, and that outputs are readily useable by estimating, programming and delivery teams.

To prepare for the wet season, CEA was mobilised to the Tujuh Bukit site in Indonesia. We used our in-house auditing process to identify where meaningful changes could be made so the haul roads could withstand tropical downpours. Our team’s deep knowledge of pavement design and construction resulted in robust designs that could be efficiently implemented prior to the rains commencing.

CEA was engaged by Fulton Hogan to complete a detailed mass haul for Willogoleche 2 Windfarm. We worked alongside the contractor’s team to produce a detailed mass haul spanning earthworks, pavements and concrete. Our analysis enabled the tender team to understand the impacts of various crushing sizes, and the foundation delivery team to know what leads were required for each pour.
