Construction is breaking ground for a long awaited hospital expansion
in Monterey, California. There is broad-based community support for the
additional
hospital pavilions that will provide much needed health programs and services
(diagnostics, treatment, and critical care) for the extended neighborhood.
The project is located on a tight, semi-urban site in the middle of a
protected forest. The critical scenic easements and local tree protection
requirements significantly limited the area available for construction.
The task of the Los Angeles office of Hellmuth, Obata & Kassabaum
Architects was to retain the ambiance of the existing buildings designed
by the acclaimed Edward Durrell Stone in the 1960s. The project scope
included the addition of two new
3-story wings, each with about 100,000 square feet of floor space. The
“Forest Pavilion” will accommodate new patient rooms. The
“South Pavilion” will house the surgical and emergency facilities
as well as the Intensive Care Unit. In addition, the existing building
will be remodeled to include diagnostic and treatment functions of the
Radiology department (X-ray, CT-scan, MRI).
The Los Angeles office of the structural engineering firm KPFF was charged
with accommodating various architectural programming needs, including
matching the floor heights of the existing Durrell Stone building. Furthermore,
high seismic forces demanded that sufficient lateral strength be provided
for this building.
 A
network of concrete shear walls 20 to 24 inches thick with extensive window
openings was selected to serve as the seismic lateral force resisting
system. The foundation system used a combination of mat footings that
extended 5 feet deep at the structural walls and isolated pad footings
at lightly loaded gravity columns. A 10-inch-thick conventionally reinforced
concrete flat slab with 4-inch drop panels was used to span 22 feet. At
the perimeter of big floor openings 20x18-inch and 20x24-inch concrete
beams were strategically added. Concrete strength was 4000 psi for both
floor system and walls.
The low floor-to-floor height (10 feet, 6 inches) of the middle of the
three levels necessitated a floor system with the least thickness possible
in order to accommodate the extensive above ceiling infrastructure. The
concrete flat slab floor system selected for the typical floors with conventional
reinforcing made that project goal possible while maintaining alignment
with the floors in the existing building. Vibration and deflection control
provided by the concrete floor framing complemented the structural rigidity
and seismic drift control achieved by the concrete walls.
