Melbourne Metro Tunnels Project

A joint project between Australia's Arcadis, Arup, and WSP with Hassell, Weston Williamson, and Rogers Stirk Harbour and Partners as architects. Projected to be completed by 2025, this 5-station underground railway aims to connect Sunbury to Cranbourne/Pakenham. For more information, please see this link.

BIM Modeler/Senior BIM Modeler

I was in charge of leading the Manila drafting/modeling team for the Swanston Street Building of the Town Hall Station. My main role is to liaise with our Australian colleagues and ensure the smooth delivery of the project. We were seconded in Australia for 3 months at the start of the project to be familiarized with the workflows & standards and to connect with the whole team. My role involved clash detection, design review, assigning tasks, model health checking; ensuring that we follow the standards and are up-to-date.

The Swanston Street building site location is adjacent and almost touching a midrise building along with other smaller buildings. Because the adjacent buildings must not be disturbed in addition to the requirement that they must be connected via a tunnel to an existing building and a new building (Federation Square building), the design team has decided to use an uncommon methodology, a mix of top-down and bottom-up construction. Bottom-up construction is the common construction methodology. This involves excavating the whole site and then constructing the building from the bottom then working upwards. Top-down construction on the other hand is different. The top floor is cast before the earth under it is excavated completing each level in the same manner until the bottom is reached, hence the name top-down (for more information, click here ). Mixing these construction methodologies proved to be difficult and challenging for both the engineering and drafting/modeling team. But through our teamwork, effort, and proper communication, we were able to successfully finish our assigned station.
