Best of 2006 Northern California Plaza Apartments opened its doors to tenants in January 2006, becoming the first new construction for supportive housing in the South of Market neighborhood. A nine-story building on the northeast corner of Howard and Sixth streets, Plaza offers 106 single resident occupancy (SRO) units. The first LEED-certified building constructed by general contractor Nibbi Brothers, Plaza Apartments became the first affordable housing development with a LEED silver certification for both the city and county of San Francisco. It was also the first project developed by the Public Initiatives Development Corp., a nonprofit development corporation of the San Francisco Redevelopment Agency formed in 2001. Project challenges were many, including being located in a high-volume traffic corridor that also has a continuous volume of pedestrian traffic. And from Thanksgiving through the New Year, there is a holiday moratorium that prohibits any construction work on the street or deliveries; no lane of Sixth St., for example, could be obstructed. In addition to a tight site, materials and logistics issues, the tenant type was changed in early 2005. Plaza Apartments was originally slated for low income residents, but in 2005 the project was brought under the wing of the mayor’s 10-year plan on homelessness included in the Direct Access to Housing program. DAH is run by the Department of Health; the tenants are formerly homeless people with disabilities that are currently being seen by department case workers. The goal of Judges’ Comments the program is to shift the burden of care off of facilities like SF General and Laguna Honda and shift them toward supportive housing developments. 31 California Construction 12/2006 Plaza Apartments, San Francisco Project Team Redevelopment Winner Owner Public Initiatives Development Corp.

The ground floor multi-purpose room was turned into the case workers’ office. On the second floor, the existing “Highly integrated synthesis of social programs, sustainable construction and urban scale-making.” office space was reconfigured to add more staff. The laundry room and lounge became the nurse’s office, exam room and psychiatrist’s office.
Best of 2006 Northern California This major restoration project overcame many obstacles to seismically upgrade a circa-1889 building and return the interior to its original grandeur and to serve the community for the next 100 years. The 45,000-sq.-ft., two-level structure is an unreinforced masonry building with wood framed floor and partitions and heavy timber roof trusses. The lower level is partially below grade and contains various community spaces. The main level is approximately six ft. above grade and contains the worship space. The scope of the project addressed four basic areas of need: 1) water intrusion problems, 2) seismic and structural defi- Cathedral of the Blessed Sacrament, Sacramento ciencies, 3) liturgical issues, and 4) antiquated systems. All wall and ceiling surfaces were decoratively repainted or restored to reflect the original Trompe-L’Oeil painting. All liturgical elements, such as the altar, tabernacle and baptismal font were made of hand-carved marble and the ambo, cathedra, were made of a combination of mahogany and gilded iron. Vanir Construction Management Inc. and its designers, contractors and subcontractors utilized computer generated 3D models to illustrate detailed elements in addition to the architect’s large-scale model of the interior of the cathedral. Many full-sized field mock-ups provided the means of testing and acceptance of interior finishes. Since drawings of the original construction were long gone, Vanir prepared a set of as-built drawings of the building— nearly 300 of them—during the condition assessment. Another challenge was access to the exterior building repairs, which was assumed to require scaffolding the entire façade. However, the cathedral’s dome and three towers were so tall that installation of scaffolding was not only extremely expensive but also caused increased safety 33 California Construction 12/2006 Project Team Restoration Award of Merit Owner Cathedral of the Blessed Sacrament & Rectory, Sacramento Architect Beyer Blinder Belle Architects & Planners, New York General Contractor Harbison Mahony Higgins Builders Inc., Sacramento Construction Manager Vanir Construction Management Inc., Sacramento Major subcontractors Armour Steel, Rio Linda; Artisan Glass Works, Sacramento; Capitol Architectural Products Co., Sacramento; Cleveland Marble, Orange; Quarryhouse, San Anselmo; Teichert Construction, Davis. concerns. So the contractor employed steeplejacks, high-wire artisans and trades people (most of whom are also mountainand rock-climbing enthusiasts) to complete the required scope of work. Vanir said the project was a model of Judges’ Comments “An outstanding historic project, the cathedral kept the grandeur of its structure while being consistent in its use and contribution to the community.” teamwork and collaboration. The result was on schedule delivery of a very complex restoration of a very fragile historic building.
