Answer: No bond is required for this project. The Standard One-year construction warranty will be required, however if the manufacturer of the ramps/deck provides a longer warranty that is to be passed on to USACE and provided in a warranty management plan.

Q10. For a ramp to be considered ADA compliant it must run on a 1:12 slope, meaning for every one inch of rise you need one foot of ramp. The plans submitted show an elevation for the deck of 40 inches, which is where the door threshold on the units would be as well. Based on this elevation the minimum amount of ramp required to be ADA compliant would be 40 feet. The current plans show a ramp length of 23 feet, which would not be considered compliant. Please advise.

Answer: Contractor To verify in field all measurements and provide shop drawings of all pre-engineered elements (deck, ramp, stairs, etc.) for Government acceptance and shall meet all ADA requirements. Our plan was not drawn out fully to be compliant, but rather just a concept drawing.The actual pre-engineered systems to be provided must be fully compliant. See Figure one.

Q11. The Solicitation plans show (2) new metal stairs and (2) Existing metal stairs to be salvaged and relocated. The only data shown regarding the existing metal stairs is on the picture of the offices from Exhibit 7 "General Specifications." Based on Exhibit 7, no handrails seem to be present on the existing stairs and it does not appear that the existing stairs are tall enough to reach the threshold of the trailers. Without more details on the existing stairs, it may not be possible to integrate them into the new ramp and platform system.

Please advise if:

a) you would like us to bid for all new stairs for a total of (4) sets of stairs ensuring compatibility with the system or

b) you can provide details and dimensions on the (2) sets of existing stairs to remain and we can attempt to bid on integrating them into the new system with added handrails onto the existing stairs.

Answer: There are two metal stairs. See Appendix A, and pictures provided here.

Q12. Gravel section thickness underneath platform. Please confirm.

Answer: See PWS paragraph 2.2.3 Class 2 gravel is acceptable, 20mm or ¾ inch. Recycled Class 2 base composed mostly of Asphalt Concrete is also acceptable. Minimum of 1.5 inches thickness of gravel is required.

Answer: See appendix B. Contractor to verify in field all dimensions.

Q14. Civil grading plans are not provided for concrete sidewalk elevations. Need sidewalk elevations provided on a plan.
