Comment at Site on November 21, 2016

High Tides/Construct ion

At the site survey speakers requested that due to the high tides, we should make the foundation for the tower, shelter and maybe generators about 1 meter above ground level. Page 9 of the SOW 1.02 allows the contractor to determine the adequate height. Further J2-2 does not specify these items be raised to that elevation. If the Government is requesting the tower, shelter, and generators be 1 Meter above ground please state so in the solicitation.

SOW pg.

24: State ment of work 3.01 states transportat ion from Bogota to Buenavent ura shall be provided by the contractor.

Options

The Government then includes -Bid option 1 and bid option 2 :Option 1: Buenaventura –Tumaco and Option 2: Tumaco –Candelilla. It would seem the Government would need both options. If the Government selects only option 2 will the Government handle at its expense the transportation for option 1? Why are there options if in SOW 3.01 the Government states all these elements shall be shipped to Tumaco by the contractor? This seems to be conflicting, please clarify.
