When the board of the Salvador Dali
Museum in St. Petersburg, FL determined that they needed
a new museum, they used the opportunity to create an iconic
new facility that would represent the spirit of the artist
the museum was dedicated to.
The new Salvador Dali Museum lies at the southern tip
of downtown St. Petersburg, just across the street from
Tampa Bay, and along the track of the Grand Prix of St
Pete IndyCar street race. The 74,000 square foot facility
includes over 13,000 square feet in new gallery space,
a library, an auditorium, a café, and a multi-purpose
room for functions. The building features an extensive
free-form glazing system on the north and east sides of
the building, skylights to allow natural lighting for
Dali’s major works, a rock garden, and a 70 foot
tall spiral concrete grand stair.
The structure itself is cast-in-place concrete with mild
reinforced one-way slabs and beams. The exterior concrete
walls are architecturally exposed elements that act as
load- bearing members and the primary moisture barrier
for the building. A self-consolidating concrete mix was
used to allow the 18-inch thick walls to be poured in
14-foot high lifts, flowing around window and door openings
while limiting lift lines and leaving a smooth exterior
finish in the concrete surface. The mix design included
a crystalline waterproofing admixture to prevent moisture
from passing through the walls during Florida’s
rainy season.
The building will house the world’s largest private
collection of Dali’s art, but the 1st floor sits
only 10 feet above mean sea level in a hurricane-prone
coastal area. To protect the priceless collections, all
gallery, library and vault spaces are located above the
1st floor. Additionally, the owner required that the building
itself be able to withstand a design wind speed of 165mph.
The primary glazing system, designed by Novum Structures,
could not meet this high wind requirement, so the interior
galleries, rare book library and vault spaces were hardened
to withstand exterior wind pressures, should the building
envelope be compromised.
One of the major architectural design features is a helical
grand stair running up the center of the building from
the ground floor to the galleries 30 feet above on the
3rd floor. The spiral shape continues 28 feet above the
3rd floor and tapers down to a point at the top. Dali
was fascinated by the DNA structure as well as the recurrence
of the golden section in nature. The single helix was
selected as more economical than the double helix stair
originally proposed. The 14-inch wide wall stringer member
is the primary load carrying element in the stair. The
treads cantilever off of the stringer and also add lateral
stiffness to the structure, to help prevent unwinding.
During construction, the stair was unshored and reshored
between lifts before locking it into the 3rd floor structure.
This was done to minimize stresses in the stair, and to
allow as much natural deflection of the coiled shape to
be built into the treads and risers as the stair was erected.
Construction began in January of 2008. The new Salvador
Dali Museum will open in January 2011. |

This project is a new 60,000
SF Naval Facilities Engineering Command Building located
at Naval Air Station, Jacksonville, Florida. The new
facility houses the Naval Facilities Engineering Command
that was relocated from Charleston, SC along with the
Naval Facilities Engineering Field Activity Southeast,
Public Works Center Jacksonville and Regional Engineer
staffs.
The building includes a two story administrative facility
with a 3rd floor mezzanine open to the 2nd floor below.
Key elements include:
- Elevator
- Raised access flooring
- Underfloor air distribution
- Moveable wall systems
- Emphasis on natural lighting
New walkways, landscaping, pavers site utilities and
roadway demolition were included on the building exterior.
Design Goals included:
- Energy efficiency
- Functionality
- LEED compliance
- Being aesthetically “showcase” building
- Comfortable, safe and providing flexibility for
future changes
The main construction goal was providing a quality built
facility on time, within budget and with no safety infractions.
These goals were reiterated in the Partnering Agreement
signed by all participants, government and Haskell alike.
All goals were met and the project was a complete success!
