> Hayden Ferry Lakeside
Hayden Ferry Lakeside will be the first luxury mid-rise condominium
complex in Tempe, Arizona. Located on the Salt River with a gorgeous
beach and breathtaking views, the project will ultimately encompass
four or more mid-rise towers with underground parking.
The architecture will reflect traditional southwest ambiance, with
cladding materials of native stone and precast concrete. The buildings
will vary in height from eight to fourteen stories and include six
luxury units on a typical 90’x 125’ floor plate. Upper
penthouse floors will contain two to four larger units. Every unit
will feature a spacious balcony.
Due to variability in the underlying soils along the Salt River,
the building foundations will be supported on piles. Because of
the difficult installation conditions expected, the structural engineer,
Cary Kopczynski & Company, was challenged to create a design
that would minimize the number of piles. This was accomplished through
a lateral load carrying system that mobilizes the entire building
frame for resisting wind and seismic forces. All slabs and columns
will participate in resisting lateral loads, resulting in overturning
forces to the foundation that fall within the pile allowable capacity
for short term loading. No additional piles will therefore be required
for lateral forces.
According to Cary Kopczynski, the structural frame for each building’s
superstructure will be constructed entirely of cast-in-place concrete.
Seven inch thick floor slabs with typical spans of 27 feet will
be post-tensioned with half inch diameter unbonded monostrands.
Typical columns are 18” x 18” in the 8-story buildings,
and 18”x 24” in the 14-story buildings.
Concrete strengths are 4,000 psi in the foundations, 5,000 psi
in the post-tensioned slabs, and 6,000 psi for all columns. Set
retarders and ACI hot weather concreting provisions will be used
to support the proper curing of slab pours in Tempe’s ultra
scorching weather.
As Kopczynski points out, concrete was the natural choice over
steel for Hayden Ferry Lakeside. Its high quality, fire resistance,
compatibility with numerous architectural styles, and minimal floor-to-floor
height made it the ideal choice. Constructability of the concrete
frame is efficient. With all columns aligned in the transverse direction
will allow an economical fly-form system to be used for all buildings.
Optimizing the number and location of concrete walls will result
in an exceptionally fast construction schedule. The first building
is expected to be complete in 2006 at a construction cost of approximately
thirty million dollars.
