Question 2. The description of Work on attachment

J is little confusing: "This shall be done while maintaining an active water system on selected tanks unless National Park Service (NPS) can maintain a bypass to allow each tank to be drained during the work."

Answer Question 2. Divers will follow NSF disinfection procedures, (Bleach water spray down before entering tanks etc.)

Question 3. There was not enough information on the reservoirs regarding dimensions, depths to put together a bid price.

Answer Question 3. Fort Cronkhite and Fort Baker tanks are both 400,000 gallon above ground concrete tanks. Each of the sites are divided in half with a concrete separation wall making each cell 200,000 gallons. Each of those cells is approximately 20 feet in depth, rectangle in shape. The last tank at the Fort Barry site is a round concrete tank buried in the hillside.

200,000 gallons total and once again divided in half with a concrete dividing wall. Once again approximately 20 feet deep.

All tanks have permanently mounted ladders inside for entry.
