San Francisco-based Swinerton Builders have taken to their blog to spotlight the Building Information Modelling journey of a recent courthouse redevelopment project.
The Prince Jonah Kuhio Kalanianaole (PJKK) Federal Building and U.S. Courthouse project in Honolulu, Hawaii, saw the 30-year-old law-related building undergo a complete interior replacement of the MEPS and envelope, allowing for a larger tenant occupancy in the actual courthouse.
The main challenge of the refurbishment was to remove conduit of audio-visual system rough-in within the ceiling between the third and fourth floors. According to the blog post, the conduit was “virtually impenetrable” due to the dense population, so the project team needed to use BIM effectively to find the best solution of re-coordination new MEP infrastructure scheduled to be positioned in that particular space.
VDC tools were utilised to scan the area and create a digitized version of the current situation, and then they BIM team used the scan to collate relevant information to generate a 3D model. Following the creation of that, this extra new 3D model was then incorporated into the main collaborative model hosted on BIM 360 Glue.
Cloud-based collaboration was vital here to ensure that all parties in the project workflow were aware of the problems and ultimately, know how to solve them. As the blog states, taking the process to the cloud “allowed the project team to streamline the decision-making process and minimize schedule impacts” as best as possible.
Quality control subcontractor work was also boosted thanks to on-site field leader personnel being equipped with iPads that contained BIM 360 Glue also, meaning they had access to the latest update of a model as soon as it was available.
