INSPECTION AND EXERCISING OF WATER AND SEWER VALVES ON AN ANNUAL CONTRACT

ADDENDUM #1

Q1. For valves requiring repairs under bid items 2.1C, 2.2C, 2.3C, and 2.4C in sidewalks, will the entire sidewalk section (typically 4’x5’ for internal roads and 5’x5’ for external roads) require replacement to meet the “existing joint to joint” section stated in Part 3.9 entitled (page 6), “Concrete Sidewalks/Driveways”?

A1. Yes, joint to joint and finished to match the existing sidewalk.

Q2. For driveways requiring repairs under bid items 2.1C, 2.2C, 2.3C, and 2.4C in driveways, what is the largest driveway apron section (sf) required replacement to meet the “existing joint to joint” section stated in Part 3.9 entitled (page 6), “Concrete Sidewalks/Driveways”?

A2. Driveways shall be replaced to the first joint. If no joint is present, the replacement will not exceed the Right of Way.

Q3. How many valves do you anticipate will need a blocking truck?

A3. “Contractors shall perform the work in compliance with OSHA; DOT; MUTCD and all other applicable safety regulations”.

Q4. Will back log repairs be added to any repair work orders created during assessment activities? If so, do you have an estimate of the number of back-log repairs?

A4. We have approximately 5,000 CNA/CNE fire hydrant isolation valves that will be assigned during the life of this contract.

Q5. Does Gwinnett County anticipate bringing in any new systems during the length of the new contract?

A5. No.

Q6. Can you estimate how many valves are in GDOT roads?

A6. We estimate approximately 6010 valves are located in Gwinnett DOT roads. However, this number may not be accurate as we do not confidently track this information.

Q7. Can you estimate how many valves in roads with a speed limit >45mph?

A7. We do not track this information.

Q8. Can you estimate how many valves are in state routes?

A8. We estimate approximately 750 valves are located in state roads. However, this number may not be accurate as we do not confidently track this information.

Q9. Will the contractor be paid for digging up concrete or asphalt when no asset is found?

A9. No payment shall be made for valve location efforts if the valve is identified by the Contractor as

CNL.

Addendum #1

BL087-22

Q10. How many valves will be part of the scope that have not had an assessment or repair meeting or exceeding the requirements of this scope A10. All assigned valves have had a previous inspection. We have approximately 5,000 CNA/CNE fire hydrant isolation valves that will be assigned during the life of this contract.

Q11. Will Gwinnett County consider unit prices of $1.00 to be acceptable and responsive, when it is clear that construction and/or repair related scope items cost more than $1.00. For example, the material costs alone for Items #3 and #4 for the previous contract (BL067-20) were more than $1.00, but unit pricing in that amount was accepted by the County.

A11. It is the intention of Gwinnett County to solicit an item for bid and expects the vendor to price the item competitively. Gwinnett County will hold the vendor to the submitted unit pricing for the life of the contract.

Q12. Since the Contractor cannot bill for CNLs, will Gwinnett County provide the total number of current

CNLs on record and the total number of valves in the system?

A12. We have 57,606 distribution and fire hydrant isolation valves (6”-20”). Of the 57,606, there are 670

CNL distribution valves and 12,440 CNL fire hydrant isolation valves.

Q13. For valves previously determined to be CNL under the previous contract, will Gwinnett County consider removing these from the assigned valves under the new contract?

A13. If a valve has two consecutive CNL inspections, the valve will not be issued in the assigned scope of work.

Q14. Please provide the County’s specifications and diagram for valve risers in/out of pavement and asphalt.

A14. Gwinnett County DWR allows drop in valve risers for valves that need to be raised 6” or less in or out of pavement. Drop in valve risers may be used for valves in excess of 6” with the pre-approval of the Gwinnett County DWR contract manager.

Q15. For valve risers 12-inches and less, will the County accept drop-in type risers? If so, does the

County have a specification for drop-in type risers?

A15. Gwinnett County DWR allows drop in valve risers for valves that need to be raised 6” or less in or out of pavement. Valve risers must meet ASTM A48; Cast Iron 5-1/4” shaft, 1-1/2” or 2-1/4” depth, Sigma VB26015/VB2602 or approved equivalent.

This addendum should be acknowledged on Bid Form, page 22. Failure to do so may result in your bid being deemed non-responsive.
