6) Does Construction Industry have all the latest information and documents for this project?

The latest, most accurate information is contained within the solicitation.

7) I asked earlier about the electronic design files and Amendment 1 said they will be provided for construction. I wasn’t clear that I was looking for them now for bid preparation. Is that possible?

The www.Sam.gov website does not support the upload of DWG type files (i.e.

AutoCAD file types). Should contractors want these files, they must send an email to Janice King at janice.king@usda.gov. Requests should be made prior to the quote due date.

8) Geotechnical Report / Groundwater Conditions - Please provide the geotechnical report, if available, including subsurface exploration data, groundwater elevations, and pavement design criteria. The specifications reference dewatering procedures; however, no groundwater information or anticipated subsurface conditions were identified in the bid documents. In the absence of a geotechnical report or defined groundwater elevations, contractor will have to assume groundwater is not anticipated within typical excavation depths. Confirmation is requested.

A geotechnical investigation was not completed. Groundwater is not anticipated with typical excavation depths.

9) Pavement Section – Bid Option Areas - Please confirm the required pavement structural section for all bid option areas, including: ◦ Aggregate base thickness ◦ Asphalt http://www.sam.gov/ mailto:janice.king@usda.gov thickness ◦ Compaction requirements (percent of maximum density and test method) ◦ Required testing frequency.

If capacity is found to be insufficient during construction, please confirm that corrective measures (including well upgrades or replacement) will be treated as a change to the contract. Contractor cannot assume performance of an existing system without documented verification.

See Attachment 16: Well Log. Improvements to Loop B will result in a maximum increase of 3 hydrants to the existing 15 hydrant system.

11) Water System Disinfection, Testing, and Sampling Requirements - Please confirm the specific disinfection standards (AWWA reference), sampling protocol, laboratory requirements, number of required passing samples, and testing agency requirements.

18. C7.0 has the 8 tent sites 91 – 98 called out specifically as “NOT THIS PROJECT” but the option bid sheet shows making marker signs for these sites. Are these sites being constructed by others and what option do their signs need to be in?

See specification Section 01250, Part 3, 3.2.Q.2 This Base Item requires Contractor to provide all signs shown on the Sign Plan, including those that are for Optional Items.

19. C7.0 has sits 85-90 being constructed in the base bid but the signs are listed in the option item bid on C8.1, shouldn’t these be in the base bid since the sites will be constructed in the base bid or what option do the signs go in?

See specification Section 01250, Part 3, 3.2.Q.2 This Base Item requires Contractor to provide all signs shown on the Sign Plan, including those that are for Optional Items.

20. C7.0 shows the host sites at the campground entrance 56 and 57 being option items but the signage for them is in the base bid sheet C8.0. is there to be any grading or gravel of these sites in the base bid. and from other campgrounds isn’t the host site typically right when you enter, not on the way out?

Yes. The Forest Service would entertain crushing existing surfacing materials for use as gravel surfacing and/or subbase. The entire section of surfacing material, asphalt and subbase, would need to be salvaged, crushed and blended with virgin base course to attain a uniform gradation matching the specifications found in Section 321123.

24. Is Loop B to remain closed for the entire contract duration?

Loop B is to be closed when construction begins and will reopen when construction is complete. It is expected that once work has begun it will progress without interruption until completed.
