B. Elevator Machine Room: There is one (1) elevator machine room (EMR) in the building serving all 14 elevators. The EMR is accessible by entering Stairwell #1 to the 13th floor, then through corridor 1307, then up a single story Stairwell #6 to the EMR.

There are three (3) split-system, direct expansion air conditioning units located in the EMR for temperature control. All A/C units and associated ductwork, controls, fire alarm interconnect in the EMR shall be replaced under this contract since they have reached their useful life span of 20 years. This requirement supersedes the “Study” recommendation to keep the A/C units.

C. Add Option #1: Provide twelve (12) card readers in the passenger elevators cars 1 through 12, so that floors 7 through 12 call buttons are activated/light-up upon an approved HSPD-12 badge being read. The EXIM tenant on floors 7 through 12 have requested this upgrade. Contractor shall submit a separate line item with their bid to include Option #1 – Card Readers in Cars 1-12. Selecting of an FIPS 201 approved access control reader compatible with our existing access control system and suitable for elevator environments.
