1. OVERVIEW STATEMENT

The Drug Enforcement Administration (DEA) has a requirement to replace the aging and increasingly unreliable Superior Boilers located in the penthouse of the DEA Training Academy. The boilers having been installed in 1998, are at the end of their useful life and by industry standards are due for replacement. The boilers are critical in the operation of the Academy Building and the Training Mission and therefore need to be fully dependable and functional at all times which require replacement to accomplish this goal.
