Solicitation 140FC125Q0008 Havasu Boat Ramp

Questions (Q) and Answers (A)

1 | P a g e

Q1. Do we need to add footings to the ramp?

A1. Contractor to provide 8”deep (20” total from top of slab) x 8” turndown with 1 -#4 bar in the center of turndown. Turn down slab bars into the thickened slab edge and tie to horizontal bar.

Q2. The ramp doesn't appear to be 70' long, how long are we needing this to be if we are doing a removal and replacement?

A2. Existing ramp is closer to 35'. I believe that the 70' referenced in the SOW might have been in error due to the original having two identical boat ramps listed. 50' extends the ramp down to the bottom of the lagoon area. We'll call it 70' in total, including the 20' apron on the flat parking area.

Q3. The SOW has the pad at 1' thickness. Do you want us to taper the last four feet of the ramp down to about 4"?

A3. Taper slab down to 6” to provide at least 3” cover on all rebar.

Q4. Do you want us to pack in rip-rap at the bottom of the ramp?

A4. No, if we find that rip-rap is needed, we'll do that in house later.

Q5. When removing the old ramp, do you want us to separate out all the rebar from the concrete and place it in separate pile?

A5. No

Q6. Will the boat ramp stop at the water’s edge, or will a portion of it be submerged?

A6. Under normal conditions, the boat ramp edge will be submerged, currently the water is at level where de-watering/sheet piles are not required, and the total length of the ramp is exposed.

Q7. Does the rebar need to be epoxy-coated?

A7. No

Q8. Is bonding (Bid/P&P) required for this project?

A8. There is no bid bond requirement. The payment bond/performance bond requirements are dependent upon the award amount. If your bid is over $35,000 a payment bond will be required; over $150k and both payment and performance bonds will be required.

Q9. Is there a turned-down slab around the perimeter?

A9. Contractor to provide 8”deep (20” total from top of slab) x 8” turndown with 1 -#4 bar in the center of turndown. Turn down slab bars into the thickened slab edge and tie to horizontal bar

Q18. Per the pre-bid site walk, please confirm if the ramp shall be revised in the SOW from a

16’W x 20’L Landing and a 16W’ x 70’L Ramp to match the field measurements taken during the site walk.

A18. Correct

Q19. Per the pre-bid site walk, please confirm if the new ramp shall be installed with a straight entry approach angle to match the existing site’s entry/exit point.
