Sustainable concrete design for interchange

The construction of a major road interchange project in South Australia is expected to start soon with the contractor promising a sustainable design by reducing material quantities and minimising concrete.

Acciona Construction Australia has been awarded the design and construct for the $120 million Majors Road Interchange Project in the southern suburbs of Adelaide. The project involves the construction of new on/off-ramps for the Southern Expressway at Majors Road.

“Combining our local knowledge with global expertise enables us to bring an innovative perspective to the development of this project.,” Acciona stated. “For example, our sustainable design solution includes reducing material quantities such as minimising concrete use by reducing retaining walls, decreasing underground concrete stormwater, and shortening ramp lengths and bridge girders.”

Construction on the Majors Road Interchange Project is expected to begin in the last quarter of 2023, with final project completion expected toward the end of 2025.

The South Australian Government and Acciona revealed the project is expected to support approximately 245 full-time-equivalent jobs per year over the construction period.

“As part of this commitment, approximately 10% of the workforce will consist of apprentices and trainees; 12% will be comprised of Aboriginal employees; and 4% will be individuals facing barriers to employment or long term unemployed. To complement this, the project includes a local industry participation target of 95%,” Acciona confirmed in a statement.

Danny Parkinson, Acciona’s Regional Manager for South Australia, said the company has a strong relationship with South Australia and will continue to partner with service providers to engage local people to execute the work. The project presents multiple local employment and procurement opportunities, according to the company.
