WTC Investigation Contracts
External Experts and Contractors that Supported the WTC Investigation
NIST augmented its in-house technical staff with experts from outside NIST who could contribute significantly to the goals and objectives of the WTC investigation. In most cases, this was accomplished through contracts that included specific deliverables required for successful completion of the investigation. Awarding contracts on technical tasks allowed NIST access to capabilities and expertise available in the private sector and allowed efficient use of in-house staff resources on the WTC investigation. In addition, an administrative services contract was awarded to Science Applications International Corporation (SAIC) in August 2002 to support the two-year investigation.
