Investigators Research Cause of Recent Glass Canopy Collapse
July 21, 2010
Last Friday a glass canopy located at 300 Prospect Street in Hackensack,
N.J., fell onto a parking garage two stories below. According to
the Associated Press (AP), "the garage pancaked when the canopy
fell on it, [and] the top of the garage, level with the street,
was littered with dirt, debris and glass, and the pavement split
into chunks." Investigators are looking into what caused the
canopy to fall from the 22-year-old building, and though consumer
media was quick to report it, some industry experts say the collapse
may not have been caused by the glass.
According to a Fox News website, engineers found a crack in at
least one of the approximately 100 columns that support the building
[and] fire officials said the garage came crashing
down when a glass canopy from the top of the apartment building
next to it fell. Its yet to be determined what exactly caused
the collapsewas it a failure of the canopy or a structural
issue, such as problem with one of the columns?
The contract glazier is believed to be a company called Corporate
Glass, which is no longer in business, and the general contract
is believed to be Mahony Troast, also no longer in business.
While investigations are underway to determine whether or not the
canopy was constructed as a complete engineered system, Bob Price,
national sales manager with J.E. Berkowitz (JEB) in Pedricktown,
N.J., says that though JEB did not supply this particular canopy
system, as a company that does supply engineered canopy systems,
they are concerned about why the structure collapsed.
It goes back to the engineering; was it something [a glazing
company] did on its own with parts and pieces or did they use an
engineered system? Price questions, noting that this is a
subject into which research is still being done.
According to Price when it comes to selling engineered systems
that have a PE stamp, such as those sold by his company, sometimes
the pricing issue is a concern and they are subject to value engineering.
Its jobs like these where having the right combination
of engineering and people is extremely important, adds Price.
If the glass canopy is determined as the cause of the collapse
questions and concerns could arise over liability, warranties and
guarantees, as both the contract glazier and general contractor
are no longer in business.

in 1988 and Equity Residential Properties of Chicago bought it in
