About this file
This is Addendum #5 to Request for Quote 26-015-JG issued by Kissimmee Utility Authority (KUA) in Florida on February 26, 2026, concerning the purchase of Variable Frequency Drives (VFDs) and motors. The RFQ seeks three VFD units and motors for chilled water air handlers, with preferred brand Yaskawa, though any brand is acceptable. The project includes removal of old variable inlet valves, installation of new static pressure sensors if needed, installation of new motors and fan/blower sheaves, and cleaning of fans/blowers. Motor specifications include two 7.5 HP units (3 phase, 460V, Frame size S213T) and one 15 HP unit (3 phase, 460V, Frame size S254T). Proposers must acknowledge receipt of this addendum by signing and returning the acknowledgment sheet with their bid response.
The addendum addresses clarifications regarding technical specifications and contractor responsibilities. Wire gauge for the Siemens controller connection is specified as 18 gauge, with all wiring required to be in conduit. Siemens is responsible for providing static pressure sensors and integration costs directly to bidders, with Elliott Russell (407-462-2846) designated as the Siemens contact. The RFQ requests four specific data points from the VFD integration: start/stop, faults, status, and static pressure readings. Building drawings containing duct work details will be provided to the winning bidder. All addendum terms supersede verbal instructions and are incorporated into the original solicitation with equal force and effect.

ADDENDUM #5
Bidders are hereby notified that this addendum shall be made a part of the above-named Request for Quote and agreement documents. The items listed below are issued to add, modify, and/or clarify the solicitation document and agreement documents. The items shall have the same force and effect as the original bidding and agreement documents, and cost involved shall be included in the bid pricing. Bids, to be submitted, shall confirm with the addition and revision listed herein. Return this sheet with your bid response.
I. QUESTIONS
Q1. What is gauge and type of wire that needs to be ran to the Siemens controller? Will Siemens be providing the static pressure sensors or should the contractor source them? Will Siemens be providing a cost for their integration work that we are to include in our bids?
A1. Please reach out to Elliott Russell, Mobile: 407-462-2846, from Siemens and he will provide a quote for the required static pressure sensor and integration costs to all bidders. Bidders should contact Siemens directly. The required wire is 18 gauge.
Q2. What points do you want brought in on the Siemens panel? Generally, VFD points are
"Start/Stop", "Status", "Fault status", "Static Pressure". We can get more granular with "AMP's" and "Voltage" if you wanted.
A2. Points:
Start/stop Faults Status Static pressure
Q3. Can you provide drawings of the duct work for each AHU. The static pressure sensor needs to be placed 3/4 of the way down the ducts so we need to know how far that is to give an accurate price. Also, is the wiring from the static pressure needing to be in conduit or can it be exposed/open wiring?
A3. The building drawings will be provided to the winning bidder. All wiring needs to be in conduit.
