About this file
This is an addendum to a competitive sealed bid solicitation issued by the Utility Board of the City of Key West for the replacement of three 5-ton CRAC units located at 1001 James Street in Key West, Florida. The scope of work includes demolition and removal of existing Data-Aire CRAC units and installation of three new 5-ton split CRAC units with associated piping, electrical work, and integration into the existing JCI Metasys control system. The addendum provides clarification on technical specifications and equipment requirements through a questions and answers format. A mandatory pre-bid meeting was held on July 13, 2026, with written questions due by July 17, 2026 at noon, and sealed proposals due July 31, 2026 at 10:00 a.m. The contract term is one year from execution, with an anticipated award date of August 12, 2026, subject to Board approval. Project completion is required by June 1, 2027, with liquidated damages assessed at $100 per day for delays. Work must be performed outside Hurricane Season (June 1 through November 30) and during standard hours of Monday through Friday, 7:00 a.m. to 3:30 p.m.
Key technical requirements clarified in the addendum include the following: all new piping and electrical components must be replaced rather than reused; isolation valves are required at both ends of each line set; outdoor condenser coils must be factory coated for corrosion protection suitable for the Florida Keys salt-air environment; all CRAC equipment must be fully integrated into the JCI Metasys centralized control system with BACnet MS/TP capability; press fittings are permitted for refrigerant line re-piping as an alternative to brazing; marine-grade 5052 and 5083 aluminum struts may be substituted for stainless steel with verified load capacity; and the successful contractor must provide operator training on equipment operation, maintenance, and controls. No manufacturer preference exists provided equipment meets or exceeds specifications. Contractors must submit a 5% bid bond or certified check with proposals and a 100% performance bond within ten days of award. All pricing must remain firm for 120 days and include labor, supervision, materials, equipment, permitting, mobilization, overhead, and incidentals, plus a $10 indemnity fee. Contractors must maintain commercial general liability insurance of $2 million per occurrence, business automobile coverage of $1 million per occurrence, and workers' compensation insurance naming the Utility Board as additional insured.

KEYS BID 12-26 SPECIFICATIONS FOR CRAC UNIT REPLACEMENT
Addendum 1
Questions and Answers:
1. Tag info on the indoor equipment is needed; can you supply the info?
Photos attached herein.
2. Reheat/humidification vs cooling only Which configuration is required?
Dehumidification is necessary. Ideal temperature for room is 67 degrees with humidity less than 50%.
3. Project completion schedule.
KEYS anticipates awarding the contract in September, subject to Board approval and completion of the procurement process.
Work is to take place outside of Hurricane Season. Hurricane Season runs June 1st through November 30th each year.
4. Will existing piping and electrical be reused?
No. The intent of the project is to replace all associated piping and electrical components required for the new CRAC system.
5. Are isolation valves required?
Yes. Provide isolation valves at both ends of each line set (at the condensing unit and at the indoor air handler) to facilitate future maintenance and repairs.
6. Is there a preference for manufacturer?
No. KEYS has no brand preference, provided the proposed equipment meets or exceeds the project specifications. Contractors may propose any manufacturer that fully complies with the technical specifications and performance requirements.
Please include manufacturer equipment specifications in proposal.
7. Are coated coils required due to the coastal environment?
Yes. Outdoor condenser coils shall be factory coated to provide corrosion protection suitable for the Florida Keys’s salt-air and marine environment.
8. What are the requirements for the controls?
All CRAC equipment shall be fully integrated into KEYS’ centralized controls system, with all equipment capable of being monitored and controlled through the building automation/control system. KEYS utilizes JCI Metasys UI for the centralized control system. Server Room controls shall be integrated into current control system.
9. Is training required?
Yes. The successful contractor shall provide operator training for KEYS’s personnel on the operation, maintenance, and controls associated with the installed CRAC equipment.
10. Will press fittings be allowed for use for re-piping of refrigerant lines? Due to the need of burn permits for brazing of refrigerant lines, press fittings can be a safe alternative for use inside of the building since no open flame is necessary. Documentation on a brand of press fitting can be submitted for review.
Yes.
11. Can aluminum stand struts be used in lieu of stainless steel? Aluminum can be a more cost-effective solution over stainless steel and will avoid a galvanic reaction between the existing aluminum stands and the new stainless-steel struts since there is no space to isolate one metal from the other in the strut receiver of the stand.
Yes, marine-grade 5052 and 5083 may be used. Load capacity must be verified prior to installation to ensure it will support the units.
