Text version

The purpose of this amendment to solicitation W9127N-16-Q-0049 is to answer the following inquiries:

Vendor: Please provide referenced drawing 353-E507-05 Gov: See attachments one and two (a PDF is provided as well as CAD)

Vendor: What is the liquid?

Gov: The medium moving through the velocity meter is slurry. Slurry is a mixture of pulverized solid (Sand, dirt, debris, rock, etc.) and liquid (in this case water).

Vendor: Is the 20’’ pipe full of liquid at all times?

Gov: The 20" pipe is not full of liquid at all times. The piping where the velocity meter is located in the upper level pump room therefore due to the effects of gravity the slurry mixture flows down when the dredge pumps are not in operation. The pipe is usually full when the ship is dredging.
