13. QUESTION: Per specification section 01 35 13.10, Subpart 1.4.2 Over-water Transport, the government will provide transportation for men, material, and equipment. Please clarify what type of vessel will be utilized, deck space, deck capacity, and capacity of the floating crane

14. QUESTION: Please specify the location of the government furnished loading dock and capacity of the land based loading crane.

15. QUESTION: Are we to assume that this service will be available at scheduled intervals throughout the duration of construction (1 May through 30 November) without limit?

16. QUESTION: Are there any stated limited loading zones near the existing lock walls, existing tunnels, abutments, pier walls, ect.? If so, please provide the surcharge loading capacity.

17. QUESTION: The question in regards to oil-free compressors vs. oil-flooded compressors should be at the core of this compressed air system. It clearly is the driving factor in what air compressors we propose for this system. The solicitation calls for an oil-free system but does not classify the "CLASS" of air quality. I imagine that this system should be as close to ISO 8573-1 CLASS 0 as possible
