Integrated Sciences Building
Drexel University opened the doors to its new science
building, Pennsylvania's newest landmark for scientific
research and the future of integrated science, on Sept.
20, 2011. The $69-million Constantine N. Papadakis
Integrated Sciences Building serves as the new home
of Drexel's biology department and includes a 4 story
self-supporting helical stair with Glass Guardrails
and Stainless steel handrails, designed, engineered,
fabricated and erected by Anvil Craft Corporation.

One of the most challenging projects ever undertaken
by the firm, as well as the 2nd largest ever, the stair and
railing system at the Papadakis building is meant to
evoke the structure of DNA. The biological sciences are
premier here and that's evident right inside the atrium.
The entire project entailed hundreds of hours of
detailing, all done in house, 3,924 hours of Shop labor
and 6,822 hours of field labor provided by Local 401
Ironworkers.

The monumental stair and railing alone was a total of
approximately 2,800 shop hours and 2,400 field hours
to install. It included 68,000 pounds of 2 thick by 16
deep solid plate stringers, 5/16 tapered and radius
stair sub treads for the 2 thick terrazzo treads, 1,574 SF
of bent tempered glass rolled to a 53 Radius on a
32.47 degree incline plus 400 Lineal feet of aluminum
glass shoe molding and polished stainless steel
handrail rolled to the same radius and incline. All
handrails joints on the stair were seal welded and
polished in the field to create a seamless continuous
inside handrail. There is no top rail so all top of glass
edges had to align perfectly. Each run is held in place
by four hardened steel pins to allow the stair to move
independent of the poured in place cantilevered
concrete platforms.

Each section of the stair was fabricated complete in the
shop and shipped as an oversize load of 15-11 wide
by 14-5 tall. When the units arrived at the jobsite they
were repositioned on the trailer by a crane outside the
building, the trailer was backed into the almost fully
completed Atrium, where another 50 ton crane was
positioned inside the building, lifted the completed unit
into position where it was connected with the four
hardened steel pins. Each 17,000 pound section of
stair took 12 hours to pick, land in place and weld to the
point where the crane could be cut loose. Then it took
approximately 2 week per floor to complete welding and
prepare for paint.

This stair has been featured in multiple publications,
including The Philadelphia Inquirer, the Drexel Alumni
Magazine, as well as Chicago Rolled Metal Products Blog.

Anvil Craft awarded stair contract
for Statue of Liberty
Secretary of the Interior Ken Salazar today announced
that the Statue of Liberty National Monument will
undergo a $27.25 million renovation that includes
long-planned safety and other critical facility renovations
beginning in late October.

"Two years ago, when we reopened Lady Liberty's
crown to visitors for the first time since the September
11 attacks, I promised that we would continue to
upgrade the interior to makeit safer and more
accessible for all," Salazar said. "With today's
announcement, we aretaking a major step in bringing
a 19th Century icon into the 21st Century."

The National Park Service awarded the work to Joseph
A. Natoli Construction Corporation of Pine Brook, NJ, to
install code compliant stairways within the monument,
(to be fabricated by Anvil Craft Corp.) update
mechanical, electrical and fire suppression systems,
replace the elevators, and rehabilitate restrooms. The
improvements will also allow for increased visitor
access to the monument, including the pedestal and
the museum.

The National Park Service will keep the monument
open to the public through the Oct. 28 celebration of the
125th anniversary of the statue's dedication. The interior
of the Monument will be closed the following day as
work commences; however, Liberty Island will remain
open during the project and views of Lady Liberty will
remain largely unobstructed during the year-long
upgrade to the statue's interior.
