The failure to list an item or items in all affected sections of this addendum does not relieve any party affected from performing as per instructions, providing that the information is set forth one time any place in this addendum. These documents will be attached to and will become part of the Contract Documents for this project. The respondent/bidder is required to acknowledge the receipt of this addendum.

GENERAL:

1. The following changes and/or additions to the Contract Documents, via this addendum, must apply to proposals made for and to the execution of the various parts of the work affected thereby.

2. Careful note of the Addendum must be taken by all interested parties and all trades affected must be fully advised in their performance of the work involved.

3. This Addendum is hereby made part of the project requirements and contract documents for the above reference project.

Ensure to acknowledge this Addendum in CivCast when downloading this Addendum. Acknowledgement of this Addendum is a requirement in order to submit bid in CivCast. This addendum consists of the items and their associated attachments as listed below:

A. ADMINISTRATIVE CHANGES TO BID DOCUMENTS:

1. Adding additional drawings to the bid documents.

B. CHANGES TO PLANS / SPECIFICATIONS:

1.

C. QUESTIONS & RESPONSES:

Question #1: Will there be an opportunity to walk the site?

Answer: A Site Visit was held on 11/13/2023.

Question #2: Is the existing chiller operational? At what point will the temporary chiller be needed and for what duration?

Answer: Yes. The temporary chiller will only be required while the existing chiller play is being replaced.

Question #3: The current lead time on the Trane Scroll chiller is 30 weeks (210 calendar days). Would like a time extension from the granted 210 days to account for submittal review, installation, commissioning for an additional 60 days (270 total calendar days from NTP).

Addendum #3, Frank Garrett HVAC Project No. 35-00282-02-03 Form09/22/2021AM Page 2 | 2

Answer: A split NTP will be provided to allow for the long lead time of the chiller.

Question #4: Will a building permit be required or just trade permits? if a building permit is required, who is paying for the permit review and building permit?

Answer: Trade permit only.

Question #5: Will COSA be providing lab testing for the new chiller pad?

Answer: Yes.

Question #6: Pipe sizes for the domestic cold water and sanitary sewer are the only pipe sizes shown.

Pipe sizes for the domestic hot water and hot water return are not shown. In order to price these systems, all pipe sizes will be required, and site visit is not enough time for us to do this.

Answer: See Addendum #3 drawings for pipe sizes.

Question #7: What are the pipe sizes to all new chilled water piping? Not shown on drawings.

Answer: See Addendum #3 drawings for pipe sizes.

SIGNED AND SEALED BY CONSULTANT (Engineer/Architect of Record) By signing and sealing this addendum, the Engineer/Architect of Record acknowledges that the sign/seal is only for changes/clarifications to the items associated with the Engineer’s/Architect’s work referenced in this addendum.

CONTROL SEQUENCE FOR CHILLED WATER SYSTEM:

1. SYSTEM DESCRIPTION: THE CHILLED WATER SYSTEM CONSISTS OF ONE AIR COOLED SCROLL

CHILLER AND TWO VFD CONTROLLED CHILLED WATER PUMPS PIPED IN PARALLEL FOR

LEAD/STAND BY OPERATION. LEAD/STAND-BY STATUS SHALL BE ROTATED BY THE BAS

WEEKLY FOR THE PUMPS.

2. CHILLER START: UPON CHILLER ENABLE, THE BAS SHALL ENABLE (SOFT START) THE LEAD

PUMP, RAMP THE SPEED OF THE PUMP TO THE DESIGN FLOW RATE AND MONITOR STATUS

VIA CURRENT SENSOR. ONCE CHILLED WATER FLOW IS PROVEN VIA THE FLOW SWITCH, THE

BAS SHALL ENABLE THE CHILLER. THE BAS SHALL MONITOR THE CHILLER VIA BACNET MS/TP

AND ALARM IF THE CHILLER FAILS. THE CHILLER'S FACTORY CONTROLS SHALL MAINTAIN

THE LEAVING WATER TEMPERATURE SET POINT OF 44F (ADJ.). THE BAS SHALL ENABLE THE

STAND-BY PUMP IN THE EVENT OF A LEAD PUMP FAILURE. THE BAS SHALL ALARM IN THE

EVENT OF EQUIPMENT FAILURE.

3. CHILLER STOP: WHEN THE CHILLER IS COMMANDED TO STOP, THE BAS SHALL DISABLE THE

CHILLER AND DISABLE THE CHILLED WATER PUMP.

4. FREEZE PROTECTION: IN THE EVENT OF AN EVAPORATOR LOW TEMPERATURE ALARM, THE

BAS SHALL ENABLE THE CHILLED WATER PUMP AND OPERATE IT AT THE DESIGN FLOW

RATE.
