STRUCTURES

Jolly Giant Housing
Location: Humboldt State University, California

New student dormitories at California State University at Humboldt were constructed on a steeply sloping hillside. Existing redwood trees were saved by careful design of building site and stepped concrete foundations on grade beams.

Three new 3 level dormitories and a central dining and community center building were constructed for this project. Conventional timber framing was used for floors, walls and roof framing.

Kimball Hall
Location: Stanford, California

Stanford University student housing Kimball Hall, provides housing and dining facilities for 200 Stanford Students. This new dormitory building is three story, Type-V, wood framed construction. The construction included a 66,200 sf. dormitory and an adjacent 10,200 sf. dining room. The 4-acre site is located on campus in the Manzanita Park Housing Area at Campus drive East and Escondido Road.

The design of Kimball Hall complements the adjacent residences, Branner and Toyon. Structural design included seismic performance and detailing to provide rugged earthquake performance. Special structural details included are seismic drags and struts, plywood diaphragms and shear walls, full height self compensating steel rod hold-downs, and steel braced frames in the lobby, elevator, and stairway cores.

Ana Hotel
Location: San Francisco, California

This 35 story, 700 room hotel was opened in the 1980's as the first private project of the City of San Francisco Redevelopment Agency Yerba Buena District Development. This steel framed hotel is located two blocks from Moscone Center and close to San Francisco's financial and retailing centers. Over 500,000 SF of floor area, including two underground levels, accommodate parking, two restaurants, conferences, and two world class restaurants.

A seven foot thick concrete foundation mat supports over 5500 tons of welded steel frames provide the structural skeleton for the first class facility. Uniform steel detailing and speedy erection of the steel framed structure, allowed the hotel to open only 17 months after construction commenced.

Crestmarin Apartments
Location: San Rafael, California

This 220-unit apartment development includes a recreation building and 20 buildings, with a construction cost of $10 million. The project site is a rock quarry on top of a ridge, with the buildings on the edge of the crest.

We provided structural design for the buildings of four different designs. One group is three-story residences resting on a post-tensioned concrete slab. The others are two-story construction.

All of the residential buildings are of standard timber joist and stud construction with prefabricated timber roof trusses.

The lateral-load-resisting systems consist of plywood sheathing in the residences and concrete shear walls for the first group's basement levels. Each foundation system required a field survey and a unique foundation plan to specify the bottom of footing and wall heights. The buildings are founded on spread footings. The footings were dug to keep the foundation a least seven feet from the edge of the slopes.

Careful coordination of the site topography, garage clearances, site access and grading led to minimal site grading and a well-designed construction package.

Hanover Terrace Apartments
Location: Oakland, California

Hanover Terrace is a 224-unit apartment complex located near Lake Merritt, in Oakland. The complex includes three and four levels of timber framed apartments supported by a post tensioned concrete podium level. This concrete is elevated one story over ground level parking. C+D Structural Engineers provided a seismic vulnerability assessment to the new owners and determined that the constructed residential units had inadequate strength for an expected Hayward Fault Earthquake. This active earthquake fault is 4 miles from the site.

The construction included adding 34 new four story welded steel frames, new plywood shear walls and tie down anchors. The new seismic system is designed to meet a performance level of reduced damage and continued occupancy after earthquake.

101 Telegraph
Location: San Francisco, California

This is a unique project on Telegraph Hill in San Francisco. An existing three-story multiple unit residence was remodeled and another new four unit building was constructed on the adjacent vacant lot. Access to the new building parking level was through the existing building and because of fire rating and occupancy, the new building was noncombustible steel frame with metal stud partitions. A concrete filled metal deck was used for the garage and floors with this solution providing the investors a very marketable and profitable project next to the Filbert Steps and the home of the Telegraph Hill parrots.

University Gardens
Location: Menlo Park, California

University Gardens, located in downtown Menlo Park, is a mixed-use developed with 12,400 sq. ft. of residential and 11,890 sq. ft. of commercial space as well as 21,000 sq. ft. of on-site parking.

We designed a post-tensioned slab providing the open plan necessary for a basement parking garage and acting as a "table" to support the timber-framed residential and commercial buildings. The two-story commercial building fronts University Avenue with the individual units encircling a central, open courtyard. Two stories of residential units, located behind the commercial building, also wrap around a separate, interior plaza containing planters and a fountain.

Our structural system employes reinforced concrete columns and foundations and reinforced masonry walls to support the flat post-tensioned slab with drop panels at the columns. The timber framing includes both standard "stick" construction (i.e., studs and joists) and pre-fabricated floor and roof trusses. Split-face concrete masonry unit walls were incorporated into the architectural and structural systems of this $5.2-million project.

The project is unique in that it combines a commercial office street frontage with a 19-unit apartment complex. Long-span timber/metal truss joints are used to frame the office building, while conventional timber stick framing is used for the residential portion. Seismic loads are resisted by masonry shear walls in the basement garage and by plywood shear walls or masonry walls in the timber buildings above.
