SUMMARY OF CHANGES

QUESTIONS AND RESPONSES:

1. Question: Within the Bid Documents, Section 01 19 40.00 29, Part 3.2; the first paragraph calls for soundings to be taken at 25 foot intervals perpendicular to the project baseline. In the past, Stations 20+00 through 49+49.20, have been very problematic when running perpendicular to the baseline as the wind, and consequently seas, move up the channel. The requirement to run perpendicular to the project baseline may cause additional data acquisition time, additional weather days to be taken, and uncertain data quality to be acquired. In the past, we have been allowed to acquire data running parallel to the project baseline. Would you please consider rewording the bid documents to reflect the method used in previous years and to address the special requirements of this harbor?

Response: The request has been considered, however we do not propose to reword this section. The intent of the wording in Section 01 19 40.00 29 Para. 3.2 is to ensure that the break in slope and the side slopes at the dredge cut limits along the perimeter of the channel are adequately captured in both the pre and post surveys.

2. Question: Within the Bid Documents, Section 01 19 40.00 29, Part 3.2; the second and third paragraph call for the pre and post-dredge survey to be conducted within the entire survey limits (the area within the construction limits). The Dredged Material Placement Area, as shown on sheet W-3 of the provided drawings (Amendment # 3), falls outside of the survey limits. Does this mean pre and post-dredge surveys are not required within the Dredged Material Placement Area?

Response: Yes, pre and post-dredge surveys are not required within the Dredged Material Placement Area.

Please note that Profile P8 is required for the post-dredge survey and it falls partially within the Dredged Material Placement Area.

3. Question: Within the Bid Documents Section 01 19 40.00 29, Part 3.2.2; the first paragraph calls for quantity computations to be calculated using the average-end-area method. Each successive hydrographic survey quantity calculation is to be performed using the composite method. Is this correct? Would USACE consider both pre and post-dredge quantities to be calculated using the composite method as in previous years?

Response: Section 01 19 40.00 29 Para. 3.2.2 should read "composite" method for both pre and post-dredge quantities calculation. See amendment #4.
