by the California Office of Statewide Health Planning and Development (OSHPD), which is the agency approving building and design
permits for the work.
"This is very complex work - we are working within an operating
hospital and demolishing areas that are adjacent to the operation
room and [post-op and recovery areas]," the representative says.
"Coordinating our efforts with facility staff has been paramount."
The west wing make-ready work, which is slated to conclude in
October, also includes construction of a new lobby and new exterior façade.
Portions of the building are still being permitted and designed.
The project's design team includes architect Perkins Eastman Inc.
and landscape architect SWA Group. McCarthy and the design team
are using 3-D modeling to manage design changes to the project, the
hospital's new parking
garage includes solar panels on
its top level.
Construction of the west wing make-ready portion overlapped work
on two other major components of the MGH 2.0 project. A five-level,
500-stall parking garage opened in June 2016. The parking structure is designed to be a net-zero energy consumption facility, and
includes solar panels on its roof.
In addition to providing energy to the existing and future hospital
buildings, the solar panels will also provide shading for vehicles
parking on the structure's top level.
The new parking garage needed to be completed before work
could begin on the new building, as existing parking spaces were
closed to make way for construction. "There are many different activities that had to be accomplished before we could move forward, and
that was a very important one," McCarthy Building says.
Shoring and excavation work on the new hospital began in July
2016. The pouring of the building foundation concluded in August
2017. Structural steel installation is now underway.
McCarthy has already overcome a number of challenges related
to the shoring and foundation work, including a variety of soil conditions. Roughly 60,000 cubic yards of dirt were removed from the
site. In addition, the contractor is working within a tight space with
minimal laydown or storage areas.
A Collaborative Effort
McCarthy's use of the design/build delivery method on the project
has ensured close connections with several key trade partners.
"We've built a very good collaborative environment," the company says.
The contractor will soon share space with representatives of several of its partners in a trailer complex - known as a "big room" - being
built on the site.
The company says the design/build model offers Marin General
Hospital a number of advantages including cost and scheduling
certainty. The owner is also seeing another advantage of the method.
"One myth about design/build is that the owner loses a bit of
control of key design decisions early on, and that is a barrier going
forward," it adds. "In this case, Marin General Hospital hired the
design team and were able to get their preferences into the design."
The design team was assigned to McCarthy after the initial design
process took place. "We now take ownership of everything, which
flushed out conflicts early and ensure we work closely together," the
