140P9723Q0012 – Amendment 0001

Q1) 2.5.5. Stainless steel chain – what is the desired length, size needed and purpose of this?

A1) The chain runs through the center of the tether rings around the piles. Size and length to be determined primarily by manufacturer, so as to surround the 18” dia. piles and allow free rise/fall movement during tidal changes, and keep the deployed boom from rubbing against the piling surface.

Stainless steel chain provided for corrosion resistance.

Q2) When it says 20-foot tidal swing, can you clarify that?

A2) Bartlett Cove can see tidal elevation changes of 20 feet between low and high tide.

Q3) What is the desired length of the I-Beam?

A3) 20’ marine grade aluminum

Q4) Are there any photos available of the intended location?

A4) See attachments below

Q5) What is the pier structure?

A5) The facility consists of a pile supported fixed pier, gangway, floating dock, sheet pile wave barrier and two mooring dolphins. The walkway portion of the pier substructure consists of seventy-eight (78) 18-inch diameter galvanized steel pipe piles arranged in seventeen (17) bents of two to four with galvanized steel pile caps. The wider offshore L-section turns east and is made up of three bents of six to ten support piles. The pier superstructure is comprised of precast concrete panels, with galvanized steel framing and railings. Timber 12-inch diameter vertical fender piles are arranged in roughly fifteen (15) clusters of three (3) around the outside perimeter of the offshore/north end of the pier. The gangway is comprised of galvanized steel framing and railings, and composite grating panels. The top of the gangway is pinned to the end the fixed pier, while the bottom is supported by rollers on top of the floating dock. The 375-foot long wave barrier consists of coated steel Sumitomo “U” sheet piles and an upper HP14x89 horizontal wale, affixed to the west side of the offshore end of the pier. The floating dock consists of steel framing, timber deck and fender skirting, foam floatation billets. The floating dock is held in place by five steel pipe piles on the west side of the dock, with internal pipe roller guides. The mooring dolphins are comprised of a cluster of three steel pipe batter piles with heavy-duty rubberized tires stacked internally.

Q6) What is the distance from the base of the pier to the waterline at low water level?

A6) Estimated @ 30’ however the boom will be stored on the floating dock and attached to the wave barrier on each end.

Q7) What is the condition of the intended pilings for the tether rings? Corrosion / Deterioration / Marine

Growth / Concrete / Timber / Steel?

A7) Pilings have minor areas of surface corrosion and minimal marine growth

Q8) What is the frequency of deployments?

A8) Boom to be deployed for emergency spills and periodic training drills only.

Q9) When deployed, how long typically will the boom be in the water?

A9) Until spill is remedied or larger boom is set in place and up to 2 hours during drills.

Q10) What is the current water speed, prevailing wind direction, wave heights?

A10) Boom to be deployed on the leeward side of the wave barrier making currents, wind speed and wave heights negligible.
