Editor’s Note: This story was updated on April 20, 2020 to acknowledge the fluidity of the COVID-19 public health crisis. As events continue to unfold, DPR is actively working with its healthcare customers nationwide to help them meet their needs.
This October, NorthBay Medical Center in Fairfield, CA began admitting patients to its new 80,000-sq.-ft. north wing, unveiling a state-of-the-art facility that was delivered on time and under budget by a highly collaborative, DPR Construction-led project team that included design partner LBL (now Perkins Eastman). Achieving those benchmarks was the product of leveraging an integrated delivery approach along with strategic use of virtual design & construction and prefabrication.
The new three-story wing, which connects to the existing 1992 building on each floor, encompasses 22 patient rooms, eight high-tech surgical suites, a 16-bed Pre-Op/PACU, diagnostic imaging, kitchen and dining area, as well as a new central sterile department. The project also included a 20,000-sq.-ft. remodel of the Emergency Department – all completed while the hospital remained in full operation.
Co-locating in the Big Room
Delivered using elements of Integrated Project Delivery, or IPD, DPR worked alongside the owner, designer Ratcliff Architects, LBL (now Perkins Eastman), structural engineer Thornton Tomasetti and other key team members to complete the highly challenging project on schedule and under budget. The team co-located onsite in an open, big room environment that fostered collaboration, innovative problem-solving, and quick decision making.
“NorthBay’s belief in the integrated team, having us all there on site every day and being able to make timely and well-informed decisions were all keys to our success,” said DPR Project Manager Stephanie Jones-Lee. “If there was an urgent item that came up that we needed a solution to, we could just walk over to the architect or engineer, get the subcontractor on the phone and hash it out right there.”
The high level of communication and shared problem-solving helped reduce the number of RFIs and submittals and moved them forward much more quickly than might be expected for a project of this size and complexity, according to DPR’s BIM project leader Jonathan Savosnick.
“Almost all of our RFI’s were confirming RFIs, meaning we had already talked through the issue with the design partners before we sent it in for documentation purposes,” he said. “I think that made a huge difference on this project and made the process a lot faster, easier to prioritize, and more successful.”
The project incorporated several innovative or first-of-its-kind features. It was the first OSHPD-regulated project to employ the prefabricated ConXtech structural steel system. Akin to a “Lincoln Log” type of assembly, major structural components of the ConXtech system are prefabricated offsite and then delivered to the jobsite for quick assembly in the field.
“Because everything gets fabricated in the shop, it is safer, faster, and there is a lot less welding and field work to put it in place,” Jones-Lee said.
The project also was one of the first hospitals in California to incorporate brand new ARTIS pheno operating room (OR) equipment – a major change order introduced midway through construction when the equipment supplier discontinued its previous version of the OR equipment.
The team quickly adapted to the challenge.
“The new equipment added a lot of electrical conduit on the second floor, below the operating rooms,” said Savosnick. “We were in the middle of building out that second floor when we learned about the change.” They worked collaboratively to re-sequence the work and incorporate the new design solution.
Additionally, DPR employed laser scanning to verify existing conditions in the overhead ceiling space in the Emergency Department area, as well as in the Central Utility Plant. While BIM coordination was integral to the project’s success, accessing patient rooms in the still fully operational emergency department to laser scan for BIM coordination was a complicated endeavor.
“Doing BIM coordination for an existing facility that is in use was a big challenge,” Savosnick said. The team used HEPA carts and deployed field investigators to access above-the-ceiling areas in order to gather the information needed to update the model.
The VDC program had other extensions that delivered value. The team used virtual reality to review access issues and verify clearances on the roof with NorthBay facility engineers. Marking the first time that NorthBay had used VR on a project, the technology helped resolve potential conflicts before work was ever installed in the field.
