[i]The agency's $1.3 million contract with LVI Environmental Services Inc., a New York-based demolition and remediation firm, calls for the iconic towers to be removed from the pad perimeter by Jan. 13, 2011, according to Perez-Morales.
The January deadline is 200 days after NASA gave the contractor a notice to proceed with the demolition in late June...
Unlike other launch complex demolitions at Cape Canaveral, pad 39B's servicing towers will not be imploded using explosives. Instead, NASA wants to methodically take apart the structures using cranes to protect the facility's concrete foundation, which the agency plans to reuse.
The first step will be to cover the pad surface with up to 2 feet of sand, protective plates and ribbing. Workers will next move the pad's rotating service structure to a partially-retracted position parallel to the flame trench.
The towers' removal will begin in earnest by the end of September, [launch pad project manager Jose] Perez-Morales said, with the removal of cladding and support metals from the rotating service structure, leaving just a skeleton before workers move in cranes to cut the 13-story gantry from the fixed tower, Perez-Morales said.
Later this year, the contractor's attention will turn to the 25-story fixed service structure. Divided into 12 levels, the tower will be removed piece-by-piece as it was constructed.
"They're going to go to each floor, disconnect each floor all around, and then take each floor down," Perez-Morales said.
The contractor will move the remains of the structures to a parking lot outside the pad, where teams will cut the metal into smaller pieces for shipping to a recycling center.
"The equipment will come in and do the final cutting and go to the parking lot, where they will sort the metals to decide what they're going recycle and what's going to the garbage can," Perez-Morales said.[/i]
