Is this structure supported on 8"x8" posts that are supported on reinforced concrete pads see (L-501) that are supported on HELICAL PIERS? If so are there one or two helical piers embedded in each concrete pad. Also I do not see how many concrete pads there are if any. A4.

I also see the abutment and the helical piers there. A5. Boardwalk (B) is supported by three concrete piers which are detailed in 2/S-2 and D/S-2. This is included in the base bid. Alternate #2 includes work associated with constructing the three concrete piers in Boardwalk (B) with a helical foundation.

(B) Boardwalk-Please verify there are no helical piers for the RAMP. I see 8"x 8" posts on Ramp however I believe this is for the railings only. A6. There are three concrete piers in Boardwalk (B). These piers are located and detailed in sheets S-1 and S-2. The 8 x8 posts called out in Boardwalk (B) are only to support the railing, and are connected to the boardwalk rim (per note 2 in 1/L-5.02). There are helical piers included in the bridge abutment wall, as shown in detail 1/S-2. This is included in the base bid. Alternate #2 includes work associated with constructing the three concrete piers supporting Boardwalk (B) with a helical foundation. Q7. Drawing L-5.01 shows footing pad detail that has helical piers as a possibility, if soil is not able to hold the load capacity. Should we submit our quote as a unit price for all footing pads? A7.

Also (B) has a ramp with no concrete pads and 8X8 supports. Should I go with the (14) concrete pads for Boardwalk A? There isn't a detail that shows how many pads there are. A10.

This is included in the base bid. Alternate #2 includes work associated with constructing the three concrete piers supporting Boardwalk (B) with a helical foundation. Q11. I see on drawing L-5.01 the footing pad detail that mentions how the Helical Piers for the pads will be used if the soil cannot hold the required load capacity. Can you let me know if all the footing pads under the 8" X 8" posts can be submitted as a UNIT PRICE? A11.

See Appendix A and Appendix B of the Project Manual. Q14. Could the contractor perform soil tests on site before the bid? A14. Contractors will not be allowed to perform soil tests on site before the bid due to time constraints and the County s inability to verify third party information and its conformation to the design. Geotechnical information has been provided in the appendices of the project manual for all contractors to use prior to bid. Q15. Regarding alternate 1, is the acetylated lumber only to be installed for the benches and decking boards only, excluding all other joists, framing, and railing lumber? A15. That is correct. Alternate #1 is only related to the lumber for the Floating bench and adjacent decking boards.
