BOARD OF COUNTY COMMISSIONERS

Date: October 4, 2010 To: Wakulla County Sanitary Force Main Pre-Bid Meeting Attendees From: Matt Hurd RE: Force Main Pre-Bid Summary General Items:

1. All bids must be submitted to the Board of County Commissioners Administration building, 3093 Crawfordville Hwy, and clocked in by 2:00 P.M. on Monday, October 18, 2010. Bids will be opened and read aloud at 2:30 P.M. at the Commission Chambers.

2. This project is funded through the FDEP SRF program. There is no ARRA funding in this project.

3. Bidders should pay special attention to the Questionnaire in section 00415. This will give the owner a detailed view of your company’s project history and performance.

4. There are several alternates to base bid items listed for the project, including fiberglass wet well structures and potable water services. The owner reserves the right to choose all base bid options, all alternate options, or any combination of base and alternate options.

5. A significant portion of the project’s work is in FDOT right of way. All FDOT guidelines must be followed to provide a safe working environment and safe travel. Work in FDOT right of way is prohibited on the day before, day of, and day after a state holiday.

6. In order to meet FDOT restoration requirements, it is highly recommended that the contractor take video of the project route prior to commencement of work.

7. Bidders are advised that the utility corridors on portions of US Hwy 98 are very crowded. Hand-digging should be anticipated.

8. Questions will be accepted until Wednesday, October 13. All questions should be submitted in writing, preferably by email to matthurd5@yahoo.com.

Questions and Answers

1. How should bidders deal with potential rock removal?

Bid Item 2.5 deals with rock removal, including removal, disposal, and replacement with select backfill. The quantity was estimated based on depth and area of the wet wells, and on previous experience along the project route.

2. Can you elaborate on tight utilities?

Existing utilities are shown on the project plans to the best of the engineer’s knowledge. There are areas, particularly along US 98, where existing water, reuse and sanitary lines are in close proximity to each other and cross over/under each other a number of times. The contractor will be required to hand excavate where the separation between existing and proposed utilities is less than three (3) feet.

3. How will the alternates affect the basis of award?

The contract will be awarded to the contractor with the lowest qualifying bid for the combination of base bid and alternate items as chosen by the owner.

4. If fiberglass wet wells are part of a set package, can pumps be different than the pumps in the concrete wet wells?

Only pumps from the list of acceptable manufacturers will be allowed. Fiberglass wet well manufacturer’s must utilize one of the approved pump types.

5. Can directional drilling be substituted for Jacking & Boring under FDOT roads?

FDOT requires that directional drilling be installed a minimum of 10 times the diameter of the pipe. For this project, that minimum depth is 10 feet. Based upon physical requirements to reach this depth via directional drilling, there does not appear to be adequate right-of-way for installation via this method.

6. Will alternate materials be considered?

For maintenance purposes, the owner requires PVC for direct bury main construction. FPVC and HDPE will be considered as acceptable alternate materials for all directional bores. See attached updated bid tab.

7. Are HDPE transition fittings required between PVC and HDPE?

Yes.

8. How will project correspondence be handled?

All project correspondence should be via fax or email to Eutaw Utilities at 888-878-2939 and matthurd5@yahoo.com. Any addenda will also be posted at www.mywakulla.com.

Questions Received After Pre-Bid

1. Is Agru “Sure Grip” Liner an acceptable alternate material for lining concrete structures?

Yes.

2. Please clarify lift station fencing. Plan sheets 41-43 call for 6’ chain link fence with 12’ gates. Spec section 02550 and detail on sheet 53 call for 8’ chain link fence with 16’ gates.

Chain link fence shall be 6’ tall and gates shall be 12’ wide. See revised sheet 53.

3. Please provide list of pumps that are approved by Wakulla County Ordinance.

Allowable pumps shall be manufactured by EMU or Flygt.

4. Sheet #10 Station #212+50, ARV symbol is shown on the line but not labeled. Is it your intent to have ARV at this location?

Yes, see revised sheet 10.

5. Sheet #36 Station #136+50 and Station #143+50, GV’s shown but not labeled. Is it your intent to have GV’s at these locations?

Yes, see revised sheet 36.

6. It appears that some specs are out of date. May AWWA C153 be used for ductile iron fittings instead of C110? May C515 be used for gate valves instead of C509? For steel casing, may a bitumous coating be used instead of coal-tar?

Ductile iron fittings shall conform to AWWA C153. Gate valves shall conform to AWWA 515. Steel casing shall have a bitumous coating.

7. Please clarify bid items and alternates for potable water services to lift stations.

Items 1.26-1.28 apply to Lift Station 2. These are in the base bid because there is an existing water main adjacent to the site. B1.8 includes meter assemblies for Lift Stations 1 and 3. The quantity for item B1.9 includes service lines at Lift Stations 1 and 3, 40 LF at each.

8. Sheets 5 and 14 show connections to existing force main. Do both require concrete vaults? The connection on sheet 14 abandons an existing line. Does abandonment require grout or plug?

The connection on Sheet 5 shall be in a concrete vault. The connection on sheet 14 does not require a concrete vault. The abandoned line at this location should be plugged. Separate bid items have been included on the revised Bid Tabulation (Items 1.32, 1.33).

9. When installing an air release valve, can a tapping saddle be used instead of a mechanical joint tapping tee?

Yes, tapping saddles are acceptable.

10. The valve vault detail on sheet 53 shows mechanical wall sleeves, will the Connection have to be cut it? Should the piping in the vault be ductile iron? Can a tee be used instead of a tapping sleeve?

The piping in the vault shall be ductile iron. The existing force main must not be interrupted while making the connection, therefore a tapping sleeve must be used for a wet tap. The wall sleeves have been eliminated so that the existing pipe will not have to be cut. See revised sheet 53.

11. The specification for transfer switches is in conflict the electrical detail sheet. Please clarify ATS amperage and enclosure type.

The automatic transfer switch shall be 250A in a NEMA 4X enclosure.
