Project Complications & Achievements

Shamrock Civil developed a comprehensive staging plan which enabled 90% of the works to be completed without traffic control or lane closures and therefore minimised disturbance to Defence operations. Shamrock Civil assisted the designers by surveying unknown inground services and created a 3D model to assist in clash analysis and design review to accommodate the unknown services.
