Project Highlights
Innovation
We developed a highly detailed federated model to coordinate the design and resolve spatial conflicts. This model was hosted securely online and made accessible to the client team through a web-browser to support real-time collaboration.
Cost saving
We proposed 6 value engineering changes to the project which resulted in improved community outcomes and TfNSW cost savings in excess of $10 million.
Time saving
We identified several design changes and utility protection strategies that, when used together, would eliminate a complex relocation of a 500mm cast iron water main under Herring Road, a busy arterial road. This saved the project 8 months of construction and avoided significant traffic disruption.
Quality
We modelled the varying pavement treatment thicknesses required across the project to improve the residual life of the pavement and, optimised this treatment for night shift construction productivity and to avoid underground clashes.
