With three domestic manufacturers of structural steel now
up and running, building with steel is becoming ever more
economical.
This year Steel Dynamics Inc. of Indiana joined Arkansas-based
NuCor and TXI Chaparral, which has plants in Texas and Virginia,
in supplying steel to the nations construction industry.
"Steel right now is selling for $400 a ton," said
Charles Carter, chief structural engineer for the American
Institute of Steel Construction Inc. "Youre going
to see steel become even more economical, and prices today
are lower than they were 30 years ago."
The cost of the material used to be 30 to 40 percent of the
total cost of steel construction; now its 25 percent.
The other big advantage of the increasing number of domestic
manufacturers and the advance in technology is decreasing
lead time.
"In New York our foundations typically take six or seven
months," said Allan Paull, vice president for civil and
structural engineering for the Tishman Construction Corp.
of New York. "If we buy steel a month into foundations,
our steel is there when the foundation is done. Weve
seen lead times on steel go from 20 weeks to 16. Ive
even seen some arrive in 14 or 12 weeks from the time we awarded
the job."
The availability of steel is being aided by the Internet.
The Metals Service Center Institutes Web site, www.msci.org,
will soon be ready to help fabricators locate the steel thats
out there.
"Its rarely ever been the case that a piece of
steel you wanted didnt exist," Carter said, noting
the value of the Web site. "It just didnt exist
where the fabricator for the project was looking."
More than 5,000 service centers across the United States buy
steel from the mills, process it in some way, and sell it
in a slightly different form. They distribute the steel and
other metal products in the exact quantities, and the exact
form at the exact time that customers require. Fabricators
are generally the customers of service centers. Technology
has impacted the distribution of steel greatly and has reduced
costs and increased efficiency, according to MSCI. Service
centers that adopt the new technology help keep inventories
low and shipments remain high. One service center that services
the Northeast, Infra-Metals for example, built two new service
facilities in order to incorporate new technology. This too
is speeding up the distribution process.
In these ecologically conscious times, an added advantage
of structural steel in the United States is that it is virtually
all recycled content, mostly from old cars.
All of these market and technological developments point toward
good times for steel contractors.
Indeed, as is documented in the following pages, steel is
being used in at least three new residential buildings in
Manhattan, an unprecedented development in a market where
concrete has been used for multifamily construction for generations.
Steels flexibility is also shown to advantage in two
projects discussed in this issue. The new Hearst Building
designed by Sir Donald Foster that will rise on 57th Street
and Eighth Avenue and the New York Times Tower designed by
Lorenzo Piano being planned for Eighth and 41st Street will
both use steel to create significant architectural icons in
a city already known around the world for its wondrous structures
of steel and glass.
