Hamilton City Council’s Pukete Wastewater Treatment Plant was built in 1975, with a $28m upgrade in 2002 providing secondary and tertiary treatment. The council is on a mission to modernise the facility’s asset information however, a lack of as-built information, uncertain accuracy of existing data, and time-consuming location of asset information for new works and maintenance was making the job extremely hard. In order to know what they had, how to maintain it and what it would cost to keep it running, the council needed good information.
The council partnered with Beca to scope out a BIM framework to develop a data model that would integrate with their asset management system. The project team utilised drones and Lidar (light detection and ranging) laser to create a detailed model of the plant and equipment and building shell architecture. The model was then migrated to a cloud-based building lifecycle management platform, with key asset data fields attributed to elements within the model. Operation and maintenance information was attached to the model, centralising asset information to create a single source of ‘truth’ for operation and maintenance activities.
At the broadest level, the council’s BIM model is a platform for digital asset management, providing functions to visualise and interrogate more detailed information about its assets. Ultimately, the model will integrate with the council’s asset management database and financial systems, with the cloud-based lifecycle BIM platform automating the flow of information between the model and supporting applications.
While BIM is perhaps most often discussed for new builds and assets, the reality is that the majority of asset owners own many more assets then they build each year. Leveraging BIM technologies to operate and maintain existing assets enables asset owners to capture far more value in the long run.
