About this file
This is Addendum #1 to solicitation BL045-26 issued by Gwinnett County, Georgia on July 7, 2026, for the purchase of butterfly valves for the Lanier and Shoal Creek Filter Plants. The addendum addresses six questions submitted by prospective bidders regarding valve specifications, gearbox and actuator requirements, extension materials, and approved equivalents. Bids are due July 13, 2026. Key specifications clarified include requirements for AWWA C504/516 double offset butterfly valves with supplier-selected gearboxes suitable for these valve types; existing electrical actuators are to be reused where the make and model are provided in Attachment 2. The County confirmed that existing extensions between gearbox and actuator should be used when possible, with new extensions to be stainless steel if necessary. Extension stems between valve and gearbox must be stainless steel per Specification 40 27 02 Part 2.04A 2g. For Pressure Class 75 B valves, a working pressure of 75 PSI, body test pressure of 150 PSI, and disc test pressure of 82.5 PSI are acceptable.
The addendum explicitly rejected VSI BFVI Series valves and Fouress Butterfly Valves as approved equivalents, as neither product meets the double offset specification requirement. All bidders must sign and return the addendum with their quote submission; failure to do so may result in the bid being deemed non-responsive. No pricing information, set-asides, incumbent data, or contract term details are specified in this addendum document. Vendors must verify they are not on the Gwinnett County ineligible source list prior to submitting their bids.

ADDENDUM #1
BL045-26
Purchase of Butterfly Valves for the Lanier and Shoal Creek Filter Plants
I. Questions:
Q1. There are no specifications for gearboxes and electric actuators. Please provide gearbox and electric actuator specifications, if available.
A1. Replacement gearboxes are to be selected by the supplier and suitable for operating AWWA C504/516 double offset butterfly valves. Suppliers should provide gearbox details with the bid submission. There are no specifications for electrical actuators as the existing actuators are to be used. Make and model are provided in the table in Attachment 2.
Q2. Extensions will be put after the gearboxes. Will extensions be provided by the County?
A2. Existing extensions between the gearbox and actuator are to be used where possible. If new extensions between the gearbox and the actuator are deemed necessary by the supplier, they should be stainless steel and included in the Bid submittal.
Q3. According to the valve drawings in the specification, the horizontally installed valves will be buried underground, and the gearboxes will be located inside a chamber. The dimensions will be checked and if an extension is required between the valve and the gearbox, a carbon steel extension will be included in the bid submittal. Please confirm that this is acceptable.
A3. Inclusion of extensions between the valve and gearbox are acceptable. Extension stems should be stainless steel to match that of the valve in accordance with Specification 40 27 02 Part 2.04A 2g.
Q4. Please clarify the following. For Pressure Class 75 B valves, the firm will consider: Working pressure, 75 PSI, Body test pressure, 150 PSI; Disc test pressure, 82,5 PSI; Gearbox sizing according to 75 PSI working pressure.
A4. The pressures listed are acceptable.
Q5. Please confirm if VSI’s BFVI Series valves can be accepted as an approved equivalent for this solicitation.
A5. The VSI BFVI Series valves cannot be accepted as an approved equivalent. These valves are not double offset and therefore do not meet the specifications.
Q6. Please confirm if Fouress Butterfly Valve can be accepted as an approved equivalent for this solicitation.
A6. The Fouress Butterfly Valve cannot be accepted as an approved equivalent. These valves are not double offset and therefore do not meet the specifications.
This addendum should be signed in the space provided below and returned with your quote. Failure to do so may result in your bid being deemed non-responsive.
Thank you, BL045-26 Page 2 Addendum #1
