BL129-19, Addendum #1 ATTACHMENTS: Pre-Bid Meeting Sign-in Sheet Construction Access and Staging Plan 22 1116 Domestic Water Piping Pre- Bid Meeting Items:

1. See attached sign-in sheet from the pre-bid meeting on 12/12/19.

Questions/Answers:

1. Question: For testing requirements under Section 1.05 Mandatory Testing Requirements, please clarify if prior testing documents for the same system are to be provided or if this is requiring testing on the specific run of turf for this particular project? Answer: General test results on the system should be acceptable at the time of the bids. However, additional testing may be required if an issue with the materials become apparent. In-place testing of impact attenuation is required for this project.

2. Question: For testing requirements under Section 1.09 Synthetic Turf Field Specifications, please clarify if prior testing documents for the same system are to be provided or if this is requiring testing on the specific run of turf for this particular project? Answer: General test results on the system should be acceptable at the time of the bids. However, additional testing may be required if an issue with the materials become apparent. In-place testing of impact attenuation is required for this project.

3. Question: Section 26 0000-2 2.01 Product Requirements. Item H. Underground conduit raceways. Conduit shall be UL listed PVC Schedule 40. Can HDPE be substituted for PVC when underground boring runs? Answer: Conduit for below grade installations shall be Schedule 40 PVC per the technical specifications. Where the contractor is directional boring, utilize Schedule 80 smooth-wall HDPE conduit.

4. Question: Section 26 5668 - Exterior Athletic Lighting Section 1.06 B calls for a 5-year warranty. In the past Gwinnett County has required a 25-year comprehensive parts and labor warranty for the sports lighting system. Does Gwinnett County desire this same standard of service from the lighting manufacturer for Shorty Howell Park? Answer: Yes, a 25-year warranty will be required.

5. Question: Gwinnett County in the past has specified spill light and candela (glare) values in all sports lighting specifications. Are there any spill or glare light requirements for this project, and if so what are those requirements? Answer: The Carolina High Mast (or approved equal) has an optional feature called a top visor. The County would like to add this feature to the fixtures to reduce spill light and glare.

6. Question: Can there be an alternate location for the construction entrance? Answer: Please see attached Construction Access and Staging Plan for alternate construction access and staging location.

7. Question: Please clarify how storage of the bleachers should be handled. Answer: The intent is for the contractor to remove and store the bleachers on site until they are ready to be reinstalled on the new concrete pad.

8. Question: Is construction fencing required? Where will the laydown area be? Answer: The construction site must be secure at all times. However, the asphalt walking trail and restroom building will remain open (even if Alternate 1 is selected). The existing fencing around the field may be utilized as the construction barrier as long at the construction area will be completely enclosed. Additional temporary fencing may be needed. All staging and laydown areas must be fenced. See attached Construction Access and Staging Plan for reference. Temporary fencing specifications are described in Section 01 5000 1.02 D, Temporary Facilities and Controls.

9. Question: How should handicap parking spaces be addressed if blocked by the lay down area? Answer: There are additional ADA spaces in the parking lot that may be utilized. Refer to the attached Construction Access and Staging Plan for alternate construction access and staging locations.

10. Question: What are the work hours? Answer: Monday through Friday 7am-7pm. Weekend and after hours work may be allowed; however, contractor must receive prior approval from the County.

11. Question: Can you provide the sign-in sheet? Answer: Yes, sign-in sheet from the pre-bid meeting is attached.

12. Question: Is the 3rd bleacher light on 2 of the existing light towers to be added into Alternate 3 to replace the lights on the mounting arm? Answer: In Alternate 3 we are adding two lighting fixtures with the two mounting arms since we are hoping to reuse (12) existing arms/brackets.

13. Question: Is the walkway light that is on the existing light towers to be changed to LED? If it is to be changed, which pay item is that to be covered under? Answer: No, the walkway lights on the existing field light poles are to remain as is.

14. Question: Notes on sheet C-3 indicate water pipe as PVC. Detail for the Misters on C-5.1 show type "K" copper and there is no specification for domestic water. Answer: The water line from the tee at the existing water line/water source to the control valve adjacent to the field is PVC, but the line from the control valve to the mister is copper. Specifications for the domestic water are included in section 22 1116 and are attached to this addendum.

15. Question: Is type "K" required for the entire mister pipe run from the source, or only from the sidewalk shutoff, or can schedule 40 PVC be used for the entire system? Answer: See response to Question #14 above.

16. Question: Is the bid closing date for this project to remain on December 20 at 2:45pm? Answer: Bids are due to Gwinnett County Purchasing on December 20 at 2:50pm. Any bid received after this date and time will not be accepted. Please refer to the Invitation to Bid for more information.

17. Question: How much is the construction cost estimate? Answer: There is approved funding for this project. Gwinnett County expects each contractor to bid a competitive price. Award will be made to the lowest responsive and responsible bidder.
