Project Background
• CLIENT: UCSF Medical Center
• ARCHITECT: Anshen + Allen, part of Stantec Architecture
• OWNER: UCSF Medical Center
• LOCATION: San Francisco, California
• DURATION: Scheduled to open on February 1st 2015
• 878,000-gross-square-foot project
• $1.5 billion, 289-bed campus. LEED Gold and consists of 3 hospitals.

ICDC (Integrated center for design and construction)• Planning started 18 months prior to construction start and
was able to reduce construction costs by more than $100 million through the integrated virtual design and construction process.
• Co-location (The Big Room) More than 100 people from 19 companies were co-located to enhance collaboration and minimize delays in decision-making.
• Cluster teams: Nine cluster teams
• Pull and ICE sessions : Integrated concurrent engineering (ICE)
• Access to information: ProjectWise, a server-based document management system, is being used to allow for real-time access to the latest drawings and models.
• Target value design: An integrated effort set achievable cost targets per trade to reduce costs while maintaining cost, schedule, and quality.
• Virtual design or Building Information Modeling (BIM) cost-savings of $15 million and higher schedule reliability and field productivity.
• Coordination before permitting
Big Room Layout -- Matching room layout and seating with organizational structure, instead of having everyone sit with his or her respective organizations, has been proven to streamline communication in the big room environment. Large conference rooms and other meeting spaces form the perimeter of the room, with individual workstations in the interior. The spaces are color-coded on the diagram by company (e.g. dark blue for UCSF and red for DPR.) (Courtesy of DPR)

• Speed in construction with accuracy
• Portability
• Rapid Decision making
Fun Facts
In addition, the detailed BIM allowed the team to extract material quantities early on in the project with a higher level of certainty. Following are some of the quantities of materials being used in the construction of UCSF Medical Center at Mission Bay:
• 11,000 tons of steel, which is enough to build approximately 7,500 cars;
• 5 million sq. ft. of drywall, which is enough drywall for more than 700 homes averaging 2,000 sq. ft;
• 12,451 light fixtures, enough for 1,000 average size homes;
• 210 miles of conduit, enough to stretch along 3,360 San Francisco city blocks;
• 1,125 miles of wire, enough to round the bases at AT&T Park (home of the San Francisco Giants) 16,500 times;
• 85 miles of piping, equivalent of approximately 50 Golden Gate Bridges put together end to end;
• 1,783,000 pounds of ductwork, approximately 300 Ford F250 trucks (or the same as three empty 747 airplanes);
• 1,069,665 cubic feet per minute (CFM) of air supply, enough capacity to fill an Olympic-sized swimming pool in five seconds.
