1. The only transportation that is government furnished will be one vehicle to and from the island.

Materials, equipment, tools and dumpsters are to be transported to the island by contractors boat/barge. Is this correct?

Answer: Yes, one vehicle to the island at the start of the project and then it will be brought off the island when the project is complete.

2. Will contractor be able to tie one boat at government docks at mainland and the island during the contract period?

Answer: Yes

3. Does all hardware need to be domestic as specified by the Buy America act?

Answer: Yes

4. Typical boardwalk specifications that are not in contact with salt water will say to provide Southern Yellow Pine, No.1 or No.2, Dressed S4S, Treated to ACQ retention of 0.40 PCF. Decking shall be placed bark side up. Is this standard the needed lumber spec, if not, please provide.

Answer: #1 pine, .40 ACQ or equivalent

5. Typical boardwalk connections between pile cap and stringers use hurricane ties such as Simpson H2.5 Z max. Existing connections are nails. For any stringers that need to be replace, should we use nails or hurricane ties?

Answer: Nails

6. Specifications call for re-grading the boardwalk to ADA slopes. This means adjustments at the pile cap and stringer connections. All adjusted pile caps should use new hardware? For bid purposes, these slopes are 8% along the boardwalk and 2% on cross slopes?

Answer: Yes, use new hardware at the pile caps. The slope for the length of the boardwalk is 1:12 or better and the cross slope is to be level.

7. Pile cap to pile hardware at Seacamp is 1/2" hardware. Each of the 4 x 6 posts also use 3 bolts that are 1/2" diameter each. The hardware at both Dungeness boardwalks is 5/8" diameter. Should the Dungeness boardwalks replace "in kind" using 5/8" hardware or is the smaller, 1/2" hardware preferred?

Answer: Replace in kind to match existing.

8. Carriage bolts that are 1/2" diameter carry a 1" head. Typical boardwalks use timber bolts with oversized heads and washers that are 1-3/4" for 1/2" bolts. Are we to use standard carriage bolts or timber bolts for connections?

Answer: Carriage Bolts

9. Are bolts to be hot dipped galvanized to ASTM-A153?

Answer: Yes

10. Standard Form 1442 lists the work as "Replace handrails and deck of three boardwalks". Is this more a title since the work also involves posts, pile caps, stringers, marine plywood and grading?

Answer: Yes

11. At Seacamp, item 2, we are raising 225 feet where the deck dips to the sand dunes. Besides this area, the remaining boardwalk to the east also needs to be raised or adjusted to meet ADA. Do we only change grades along the 225 linear feet?

Answer: The deck to the east does not need to be raised. The newly raised section will be installed meeting the ADA standard of a maximum slope of 1:12 or better and will tie back into the existing boardwalk.

12. At Seacamp, during the pre-bid there was discussion to omit the last 65 feet of boardwalk that has been covered by the dunes. Are we to omit the Eastern 65 feet of boardwalk at Seacamp?

Answer: The handrailings and posts at this section will be removed and a short 10 foot section that will rest on the sand at this point will be installed.

13. At Seacamp, item 6, replace 750 linear feet of 2x6 stringers, the existing stringers are 2" x 10" x 12'.

Answer: The stringers are actually 2x8.

14. At Seacamp, item 8, are 4" x 6" posts to be replaced from stringers to top of rail, or do 4" x 6" change all the way into the sand dunes? Do 4" x 6" posts change only at adjusted areas or do all 4" x 6" replace?

Answer: The 4”x6” posts will go from the stringers to the top rail. All 4” x 6” posts are replaced except for the ones that extend into the ground.

Answer: Yes, .60 ACQ or equivalent
