Within the reference specification section, it is referenced that this project will provide new Shore Tie services for electrical, potable water, fire protection, sewer, bilge water, telecom and compressed air for the 5 NSCs at Pier November. It is not clear from the drawings provided or the specifications where each utility should make its connection to existing on shore services. Please provide conceptual routing and end connection points for each utility listed.

For Telecoms – Each Shore tie position will connect to the telecom room at foot of pier NOV. (RFP

Advise if it is the intent to utilize the bulkhead between Pier Mike and Pier Papa at a bulkhead to berth vessels.

The 65% RFP should not be considered. There will be no vessel berthing along the bulkhead.

This contractor must have rec’d the 65% early on. There are 28 drawings in the RFP and they noted the sheet as 6 of 8, but C-103 is 6 of 28 in the

RFP.

1.1.1 indicates a 30' offset from the bulkhead to the dredge basin.

For dredge depth of EL -30 ft below MLLW and 2 ft overdredge allowance and 4:1 side slope, the dredge elevation at the face of the bulkhead would be EL-24.5 ft below MLLW. However, section 01800 Paragraph 1.19.7.2.2 indicates the dredge depth at the bulkhead to be EL -30 ft MLW followed by a 1:4 slope to the ultimate dredge depth. Please confirm which dredge depth at bulkhead to be used for the bulkhead design.

The dredge limits are per RFP drawings. The design elevation and dredge depth of –30 MLLW (including over dredge depth) is required at the face of the bulkhead for 30-ft before the 4:1 slope to –32 MLLW (including over dredge depth).

Amendment 005 provides a new Price Proposal form. Base Item has added pricing for "Dredging" and Dredging plus Equipment Removal". Please confirm "Dredging plus Equipment Removal" is for dredging just at the failed bulkhead?
