Challenges:Adhering strictly to the 2001 California Building Code with all applicable Office of Statewide Health Planning and Development (OSHPD) amendments and Code and Application Notices (CAN) served as great challenges.
“NYA implemented an optimal structural system that allows for flexibility in healthcare planning and achieved technical excellence when collaborating with the OSHPD team during the review process all the way through construction to finish, was on budget and was ahead of schedule.”
- Rebekah Gladson, Campus Architect and Associate Vice Chancellor of the University of California, Irvine
Solution:The structural system for the foundations is a reinforced concrete mat, varying from
4 feet to 0 feet, and from 7 feet to 0 feet in thickness.
A four-story tall glass encased bridge connects the two halves of the hospital tower above the third floor and was integrated to the global system with a seismic joint at the west end of the bridge.
A connecting bridge was required between the new hospital and the existing 1A Building located adjacent to the south of the building. Working with a span of approximately 30 feet to 0 feet, a two elevator tower was designed with a 45 feet to 0 feet long overhang to span over the existing low roof of the 1A Building. The 1A Link is seismically separate from both adjacent buildings and due to the small footprint, cast-in-drilled-hole piles were used as the foundation system.
As part of the Align-Build Process, all non-structural design was performed by the appropriate sub-contractor and NYA served as the Engineer of Record, reviewing and approving the design for incorporation into the permitted documents.
