AMENDMENT 1 (14 APR 26): Amendment made to correct an admin error in the Evaluation Factors attachment.

Original: Subfactor 1.1 mentioned a "Mobile Surveillance System" by mistake.

Edit: Removed "Mobile Surveillance System" to avoid confusion on what requirement this is for.

AMENDMENT 2 (27 APR 26): To address Request For Information, and to extend the solicitation to allow time for Offerors to address the RFI answer into their quote provided.

RFI: "I was mistaken in regard to the serial# being incorrect vs. the solicitation. The issue is that the serial# does not exist with Trane anymore so the shaft size (length) is unavailable, however Trane has confirmed it being 1 of 2 different shafts. Trane is searching for the information to try and pinpoint the correct shaft. My sub will send me both quotes in hopes they will have the information by the deadline."

Answer: "We rely on our Colorado Springs account manager, Danny Marsh at 719-482-6397 and danny.marsh@tranetechnologies.com, for parts and equipment information. He didn't receive any questions from contractors, so he/she is getting info from elsewhere. I can't tell the contractor which shaft should be provided as part of their proposal." Solicitation Extended - New Date Offers Due set to Friday 1 May at 12 PM MST.
