41. Drawings C-021, C-081, C-311 show a multipurpose trail (bike/hiking trail). The trail is shown on the demo drawings and the trail is shown on new work drawings; however, it is not clear if the contractor is to install this multipurpose trail. In addition, the trail on west side runs off the drawing so we are unable to quantify. Please clarify who is responsible for install of multipurpose trail. If the contractor is responsible under this solicitation, please provide details for preparing estimate for this scope.

a. ANSWER: Trail construction is with Skyline/Hill Brady intersection project and not this project.

We have also located numerous qualified and experienced fabricators who have completed similar projects of scope and size that are not AISC certified but are interested in submitting a proposal for the steel fabrication and installation. Will the government consider removing AISC certification for the fabrication and installation of steel on this project to allow more pricing from qualified subcontractors?

a. ANSWER: AISC certification will not be waived.

64. Section 054000 paragraph 3.9 indicates that the Government will engage an independent testing and inspecting agency. Is there any other scope where the Government will be engaging 3rd party inspectors and not the contractor exclusively?
