Throughout the majority of the site, the
excavation bottomed in the Bay Mud,
which could not support the excavation
equipment, including the rigs used to
install ACIP piles and drilled shafts. So, a
working platform was installed.
As with most sports facilities, opening
day was a non-negotiable completion date:
the Golden State Warriors had its first
home basketball game set for October 24,
2019. Therefore, geotechnical issues had to
be overcome within 33 months of
groundbreaking to meet the tight schedule.
Because of the complexity of the project,
an extraordinary number of brainstorming
sessions and regular meetings were held to
problem solve with the owner, owner's
representative, design team, general
contractor joint venture, and specialty
shoring and foundation subcontractors.

Deep Foundation Testing

One of 10 ACIP dynamic load tests

For the deep foundations, drilled shafts
were used at the heavy arena cores and
where ACIP piles could not provide uplift
resistance in shallow bedrock. More than
1,000 ACIP piles were also used. To start,
an indicator pile and a load test program
were used to confirm constructability and
capacity of both foundation types. This test
program was designed to provide enough
data to make decisions when installing
production piles in the variable subsurface
conditions throughout the site - while
keeping cost in mind. Indicator piles were
installed in production locations so they
could be used for structural support. Some
of the test piles, however, were placed in
nonproduction locations so they could be
tested to failure, and were not reused.
