Major earthworks

The Major Earthworks contract was awarded to CPB Contractors and Lend LeaseJoint Venture (CPBLLJV) in August2019.On 9 September 2020 Acciona completed the acquisition of Lendlease Engineering and as such the Major Earthworks Contractor is now referred to as CPB Contractors and Acciona (CPBACC JV)

The major earthworks stage involves significant design and construction responsibilities, including moving around 25 million cubic meters of earth to support construction of the major elements of the airport, such as the runway and terminal.
