grab the third level of the roof,” Falconer explains. “It’s sort of a precarious
way to put things together because vertically all the load has to go back onto
the cantilever or out to the facade of
the building.” Another unusual aspect
is that the Galleria’s trilevel roof will
comprise diaphragms. This structural
system was selected because it will facilitate the transfer of lateral loads from
each roof level to the structural members at the ends of the building, eliminating the need for lateral bracing.
Each roof level will be 120 to 150 ft,
which will help direct wind away from
the curtain wall, Falconer says.
Unlike many laboratory buildings,
which typically have stairways at the
ends of corridors, the stairs in the Singh
facility will snake through the structure to encourage people to take the
stairs rather than elevators. These stairways will feature intermittent landings furnished with tables and chairs so
that people can gather spontaneously.
“Those ascending lounges are what are
going to make the movement through
this building very, very unique,” Weiss
says. “Those connections are places where we hope you don’t just pass
people by but maybe stop and talk.”
The stairways required a great deal of
scrutiny and additional stiffness in the
structural framing to ensure that they
would not send vibrations into the laboratories. This will be achieved by reinforcing individual members and incorporating framing for controlling
vibrations, Falconer says.
Once construction of the center is
complete, the Edison Building will
be demolished to make way for the
courtyard. The open quad, along with
the center’s transparent design and exterior and interior artwork displays, is
intended to galvanize interaction between the $92-million facility and the
rest of the campus and community.
The project is slated for completion
in early 2013. “Nanoscience is one of
the newest sciences out there,” Weiss
says. “It’s one of the few that don’t
hew neatly to disciplinary boundaries, and we’re hoping that this building and the way that it is organized do
everything [possible] to take those
boundaries away and invite brand-new dialogues.” —JENNY JONES
Call it what you will — price adjustments, indexing, or escalators. We call it an outdated
bidding policy that subsidizes oil-based asphalt. Asphalt’s slick deals cost DOTs and
taxpayers millions when oil prices rise, even when more durable materials like concrete
promise affordability and stable pricing. Learn more about asphalt’s raw deals at
