Anzac Station Roof - Metro Tunnel

WE WERE AWARDED THE ANZAC STATION ROOF IN MAY 2019 TO PROVE OUR 3D MODEL COULD DELIVER COST SAVINGS

Two months later the Cross Yarra Partnership asked us to model the base slab using our proprietary Advanced Detailing and Design Application (ADDA) with the middle platform slab to follow in 2020.

Model in 3D to detect design clashes before construction

We identified 112 clashes by modelling the steel reinforcement in 3D during the design phase. Our detailers worked with the project team to amend the design so that the steel reinforcement would fit together perfectly once construction began.

These clashes would likely have gone unnoticed in a 2D drawing, resulting in buildability issues during construction.

The 3D model eliminated the time typically wasted on steel placement by giving steel fixers a detailed view of the sequence and location of every bar using an iPad. The iPad also allowed the Designers to accurately check and sign-off the steel reinforcement by comparing the 3D model with the actual structure.

Substitute stock bar for processed bar to reduce waste

Our detailers substituted around 700 tonnes of cut and bent bar with stock bar. This resulted in a 5% cost savings ($150k) for the steel reinforcement.

We progressively reduced processed bar on the project, starting at 14% processed bar savings on the North Box and finishing with 41% on the South Box.

111,144 bars delivered to site with nil returns

The benefit of ADDA is quality throughout the project life-cycle.

* Collaboration among all stakeholders during design reviews using a 3D reinforcement model.

* Transparency to forecast six weeks ahead for procurement and scheduling.

* Enables you to get ahead of the construction program by manufacturing the bars early and pre-bundling them on Transiflats for just-in-time delivery.

* BIM compliant model for analytics, project legacy and insights on how to build SAFER, FASTER and with LESS WASTE.
