New York City's Department of Design and Construction (DDC)
issued contracts to four contractors, called Construction Managers (CM),
who were responsible for debris removal.
According to an USACE website,
each CM was assigned a zone or section of the debris removal,
and was was controlled and monitored by a three-person DDC team.
The four CMs were:
- Tully Construction, Sacramento District
- Bovis Lend Lease International, Mobile District
- AMEC Construction Management, Portland District
- Turner Construction, Baltimore District
Two New Jersey companies were among the bidders that won the contract
for removing more than 60,000 tons of Trade Center scrap.
Metal Management Northeast bought 40,000 tons,
and Hugo Neu Schnitzer bought 25,000 tons.
Neu Schnitzer East is one of the largest scrap recyclers in the nation.
President Alan Ratner of Metal Management said the company
had bought 70,000 tons of scrap steel by January of 2002.
Controlled Demolition Inc. (CDI) appeared to be key player
in the expedient removal and recycling of the steel.
CDI was retained by Tully Construction Co. Inc,
one of the site's four cleanup management contractors.
On September 22, 2001, CDI submitted a 25-page "preliminary" document to
New York City's Department of Design and Construction,
which approved the plan.
The commissioner of New York City's Department of Design and Construction
and the man in charge of Ground Zero cleanup efforts
was Kenneth Holden.
Weeks Marine Inc.
created two steel offloading areas at Pier 25 and Pier 6
in the last week of September
to accelerate the removal of steel.
Great Lakes Dredge and Dock Co. was awarded a contract for $790,500
to deepen the Pier 6 site to facilitate barge removal of debris.
