Creating the Strategy
Initially, we had to determine the overall modeling environment and toolbox to be used within the SYNCHRO 4D software. We created a massing model of the building to provide a visual demonstration of the construction sequence. It was then broken down with Gilbane’s scheduling and operations teams to define an iterative process that would support the numerous changes throughout preconstruction. Tackling an incomplete model and incomplete schedule was too big of a task for just one team to support, therefore we joined forces with our scheduling department in order to meet our fast-approaching deadlines. Knowing the project’s design would be continuously altered due to construction constraints, the schedule would also be affected. Through working in tandem with our internal teams, a workflow was developed to accommodate design changes, while also allowing schedule changes to be made instantaneously. The team was able to eliminate unnecessary rework by uncovering problems before they happened, continuously saving weeks’ worth of rework.
Executing the Strategy
The model enabled the team to proactively perform analysis on the building’s constructability, prior to construction. Our VDC team worked closely with the scheduling team for updates on the work breakdown structure. Weekly meetings were held with the operations team to refine the 4D model and the strategy. The groundwork of building the model from scratch, with all the project’s obstacles, gave the operations team useful information to communicate with the client.
Iterations
Results
Our team found a non-traditional approach to 4D usage to proactively solve construction challenges. The strategy provided for prompt decision making and a more reliable schedule. It allowed our trade partners to be coordinated more efficiently. It helped to break down communication silos and improve relationships with partners, clients, and other stakeholders. Overall, the 4D model provided considerable benefits of having structured conversations about major project decisions. This collaborative approach helped drive the innovative use of the technology.
