Can the boardwalk be placed on a ground level pile system using our Structural fiber Composite piles? Or is there no opportunity to do so? If we were to place it on a simple pile system, we can better control the settling parts that you see with the existing system. If it is not an option, then we can provide long sections to try and maintain a level walkway.

The instability of the soil and the installation of piles can cause instability or damage the natural resources of this area. A piling system will not be accepted as an option.

12.

Floating Sections: can this be a pile system also? It can save a bit of money by eliminating floats, hinge systems, hold downs, and seats. Railings can be a challenge with these also.

See answer no. 11

13. We can provide floating structures.

I would like for our materials to be considered as an approved equal so I can provide material quotes to the bidding contractors.

Product/Material Mfg requesting: Wagners Composite Fiber Technologies

Wagner did not provided adequate specifications to compare the existing decking to determine if the product can be used as an approved equal.

Based on the information provided it look that this product required a structural frame and columns penetrations.

The “Superdeck” product required for this project does not use any structural frame or ground penetration. The superdeck is made out of plastic and will be layout over the ground except for the sections in the water that will require floats.

This particular trail contains high sensible vegetation and minimum disturbances were approved to meet the NEPA and 106 compliances. The project was approved with restrictions in having minimal or no ground disturbances and penetration. Because the Superdeck product is made out of plastic and due to its density, it does not submerge in marshy terrain.

14.

This is a question in regards to the handrail requirement in the specs.

Handrails shall be included for the first 352 lf until the end of the floating boardwalk and around the new platform.

What material type is the handrail?

What is the mounting requirements?

Will the handrail be on both sides?

Will a detail be provided in the plans?

1. Handrails material: aluminum

2. Mounting per manufacturer specifications.

3. Provide handrails on both sides of the boardwalk. (Only Floating areas)

4. Contractor shall provide handrail detail per manufacturer specifications to meet ADA/ABA requirements.
