Sutter Medical Foundation Medical Office Building

Fairfield, CA

This project is a three-story, 69,948 sq. ft. medical office building. It houses family practice offices and an expanded laboratory on the first floor; pediatrics, internal medicine, oncology, rheumatology and cardiology on the second floor; and administrative offices and additional space for growth on the third floor.

The structure is a seismic moment frame steel structure with the first floor being concrete slab-on-grade and the upper two floors being lightweight concrete over structural decking.

The exterior of the building is steel framed with EIFS, thin veneer masonry and stone with a built-up roof with California Title 24 cap sheet. The HVAC system is a conventional packed rooftop forced air system.

The interior of the structure is primarily framed with steel studs and finished with drywall and wall covering.

BIM was used on this project and included the Integrated Project Team (IPT), 3-D modeling, clash detection, drawing coordination and building layout levels. The modeling produced the following results:

  • Approximately 400 clashes were discovered in the systems, subsystems and components installation. Clashes were resolved by the designer and detailers during the IPT meetings.
  • Steel structure modeling was shown along with concrete foundations, sheet metal duct runs, electrical runs greater than 2'', cable trays, plumbing lines, and the fire sprinkler system.
  • The building was built virtually using BIM before any physical work was started.
  • Development of as-built drawings for the owner were completed accurately and timely from BIM.
