WestConnex M4 Project Delays and Unforeseen Site Conditions
Accura Consulting was engaged by a major joint venture contractor to provide commercial and claims advisory services during the delivery of the WestConnex M4 East—a key stage of one of Australia’s largest transport infrastructure projects.
The M4 East comprises twin tunnels extending over 5.5 km beneath Sydney’s inner west, forming a vital link in the broader WestConnex program.
The scale, technical complexity, and urban constraints of the project gave rise to a wide range of commercial and contractual challenges during construction.
