Newest Hayden Ferry Tower
Sustains Nautical Theme
Suncor Development continues a nautical theme with its newest
phase at Hayden Ferry Lakeside. A new 12-story office tower
joins the existing structures, along with the addition of
an eight-level parking structure, retail space and outdoor
The newest phase of Hayden Ferry Lakeside is taking shape
beside Tempe Town Lake in Tempe, Ariz. The growing complex,
developed by Tempe-based SunCor Development, includes an existing
eight-story office tower, a parking garage and a condominium
tower. Phase II will add a 12-story office building, a parking
structure and retail space.
As with the first phase, McCarthy Building Companies is constructing
the new tower and garage. Once the first tower was complete
in 2002, the general contractor moved its offices to the site.
The contractor is also currently building another condominium
tower at Hayden Ferry and has been named as the contractor
for the site's 12-story $104 million Le Meridien Hotel.
DFD CornoyerHedrick of Phoenix, Ariz. designed the new office
tower, and was also the designer on phase one. The design
of both phases was heavily influenced by nautical shapes,
and the two towers have similar oval, bow-like shapes.
At the beginning of phase two, SunCor Development and the
designers met for a 'lessons-learned charrette', according
to Buck Yee, project director with DFD. "It was an all
day session understanding the good, bad and the ugly of the
things that went on with phase one," Yee said. "We
formulated a list and incorporated those components into phase
two to have an improved building."
One change was how the curved wall interfaced with the structural
"Although our details had provided the design intent,
the actual installation of how it was finally put together
was realized during the phase one construction," Yee
said. "We had the advantage of the shop drawings this
time, to help us better detail the set of documents."
The office tower sits above a single-level, 156-space underground
parking garage. While there was some compacted fill remaining
from the previous phase, workers got down to a challenging
sand, gravel and cobble soil level during the excavation,
according to Kurt Nyberg, McCarthy project manager for the
office tower. The foundation is comprised of 96 caissons,
ranging in size from three-ft. to eight-ft. in diameter. Since
the site is located at the foot of 'A' Mountain, the caissons
on the south side nearest the mountain went down 22-ft. while
the north side required 38-ft. deep caissons to reach the
A typical floor on the post-tensioned concrete structure was
poured in two halves on an eight-day cycle. McCarthy poured
the concrete for the post-tensioned structure, with Ceco Concrete
of Phoenix doing the forming. "The construction was really
fast - on the eighth day we'd pour the north half, on the
12th day we'd pour the south half, then on the 16th day we'd
pour the north side on the floor above, and so on," Nyberg
said. "It was actually a two-day less cycle than phase
one," because of improved forming methods.
The building features the same high-performance aluminum and
glass curtain wall system as the previous tower.The HVAC system
uses a variable air volume system for air distribution.
One major change from the first phase is the two-story entrance
lobby, which features textured art glass and granite, backlit
in blue light to appear like water.
"The lobby space is actually entered from where the pointed
ends of the building are, so you have to experience a long
lobby journey before you get to the center elevators,"
Yee said. "We used that as the opportunity to create
this under-the-sea theme."
The tower also features a 100-ft. metal spire that will project
40-ft. above the top of the building and will be lit with
a strip of blue LED lights. The surrounding campus will also
feature nautically-themed landscaping, including a large water
feature emulating the spray of water created by the wake of
"Phase two is SunCor's signature building of the campus,
so there is a lot of attention to detail on it," Nyberg
McCarthy is also completing the final build-out of an eight-level,
2,460-space parking garage. During the first phase, two underground
levels and the surface level were completed, with temporary
columns erected to protect the rebar in place until the second
Initially SunCor planned to complete four new levels, with
another four levels planned with a future office tower for
phase three. "We were about halfway through when they
suggested we just finish off the garage now to prevent the
hassle of closing it off in the future,'" said Justin
Dent, project manager for McCarthy on the garage.
The garage primarily features post-tensioned concrete. "There
are 31 concrete pours total for the garage structure, and
we are about a pour a week, with four pours per floor."
The garage features three-ft. pre-cast concrete panels that
will go on the outside of each level to hide the slab edge
and beams, masonry accent walls and pre-cast concrete sheer
The garage also features a three-story retail component that
cantilevers out from the garage. Continuing the nautical theme
the shape follows a radius, with the 35-ft. wide center being
the widest point.
