The project is in an existing 162,000-sq.-ft., single-story warehouse and office building in an LI zone. This building consolidated two existing facilities currently located out of state and houses research and development, laboratory, microscopy, offices and support spaces focused on the metal casting and fabrication business. The facility included (2) Air Cooled chillers, Pre-action and Clean Agent Fire Protection system. Specialized requirements include a warehouse housing manufacturing and testing equipment.

The scope included a total of (17) new fume hoods, oxygen and nitrogen piping at the lab benches and some of the labs are ISO 17025 certified. Much of the equipment, including a pilot beverage can production line, was relocated from existing remote facilities located out of state. This required many trips and careful coordination of highly specialized equipment and unique utility requirements that are duplicated in the new facility. The equipment required substantial MEP infrastructure. A majority of the equipment required substantial MEP infrastructure and significant base building modifications such as structural enhancement for overhead equipment, mechanical systems and roof top equipment.

BIM Features

Since the schedule was tight, we strongly emphasized the benefits of prefabrication of the key elements and subcontractor trades.

For example, the electricians had their junction boxes prefabricated with conduit sticking above the ceiling in order to better coordinate with other MEP systems above the ceiling.

Additionally, the mechanical subcontractor prefabricated the spool pieces for the chilled water lines for easier, faster and more accurate installation. 
Electricians ran the MC cables for the temporary lighting in such a way that permanent light fixtures could be installed using those same cables, which saved a significant amount of time towards the finishing stage since those cables were already in place. These lean construction methods helped to achieve the goal of staying on schedule and on budget.

The entire team participated in the BIM coordination meetings and OurPlan scheduling meeting. OurPlan breaks each individual activity into day-to-day tasks and takes the input from field foreman and makes them accountable to the completion of these tasks. Every morning the team gets together for 30 minutes to go over the tasks and update their status and the reasoning behind them for incompletion, if there are any. This allowed the schedule to be managed at a micro level and ensured that all tasks were completed.

DPR Construction contributes to the benefit of the client, community and the construction industry by working with high quality subcontractors and involving all team members in the construction process. By enlisting the expertise of knowledgeable subcontractors, DPR is able to build relationships, share knowledge and develop Best Practices for the industry. The owners are included on these Best Practices so they can further perpetuate the principles of Lean Construction and the benefits of BIM, prefabrication and other team coordination plans.
