BMU (Building Maintenance Unit) Commissioning Collins Square Tower 5

About This Project

Vertimax Australia was engaged in May 2019, by the overseas manufacturer and Multiplex Constructions to complete the final installation of the large and complex BMU at Collins Square Tower 5.

The two previous local independent BMU companies engaged for the installation works and the local head contractor who imported the BMU all walked away from the project and their obligations to complete the works in early 2019.

The manufacturers asked if we would review the works undertaken to date and provide comments around the balance of works. There was large number of defects and works not completed at all even though a safe to use certificate had been issued.

After several months; a lot of code writing, mechanical rectification works and electrical corrections the BMU was commissioned in August 2019 and was safe to use. It can now move through three separate zone areas to ensure the counterweight and a boom do not obstruct the building at any stage.
