The decision was made at the beginning of Construction Documents to phase both the CD's and Construction. This decision was made jointly by the Owner, Prime Architect, Construction Manager, and City of San Francisco due to a number of factors:
1. CITY REQUEST: San Francisco's Department
of Buildings requested that the permit set be issued in a series of packages
to allow city officials to manage the review process.
2. SCHEDULE: COFAM needed to maintain their originally-projected construction
completion date in order to limit the extensive "soft" costs associated
with storage and administration of their vast art collection. Swinerton Builders
recommended that drawing packages involving materials and processes with long
lead times be issued in advance of other packages to maintain this completion
date. Swinterton further advised the team that several large state projects
(which the contractor was involved with) were going to bid in the near future
and that it would be necessary to bid the de Young quickly so as to get the
project's steel order to the mill.
3. COST / INFLATION: Rising construction costs, due to a booming economy,
during the late-1990's put pressure on COFAM to move quickly. Unless the Museum
began construction on time, COFAM feared that the 5-7% annual inflation rate
of construction costs would drive the Museum's budget beyond the scope for
which COFAM could raise funds.
4. POLITICAL MOMENTUM: COFAM felt the need to project the public image that
the Museum's design and construction were proceeding without impediment. The
project eventually developed considerable public support. Because the Museum
was such a high-profile project and was still receiving considerable criticism,
the Museum's Board felt that any display of weakness could harm their fundraising
efforts.
5. DESIGN EXCELLENCE: COFAM wanted to allow as much time during CD's to ensure
Herzog & deMeuron's design intent was maintained and that Fong & Chan
were able to live up to their reputation for providing extremely high-quality
documents. The Owner realized that the tight schedule would not allow this
to happen, while maintaining the completion date, unless the project were
phased.
Construction Documents were broken down into several packages:
1. HAZARDOUS MATERIALS REMOVAL AND DEMOLITION
(began late 2001, complete in early 2002). This process had to be coordinated
with the closing of the Museum, relocation of collections into long-term storage,
and later closing of the Asian Art Museum. The Asian Art Museum remained intact
after the majority of the de Young was demolished so that the Asian's space
could be used as storage.
2. EXCAVATION AND SHORING (currently underway, mid-2002)
3. ISOLATION BEARING SYSTEM (prototype bearing in development and testing,
mid-2002)
4. STRUCTURAL STEEL (bid returned to Fong & Chan on 9/27/02)
