Requests for Information and Responses

1. Section 01 11 00, 1.1 Work Covered by Contract Documents state that the US Coast Guard Training Center (Area 1) is to be completed prior to mobilizing to Wilmington Ave (Area 2). Will the contract be allowed to mobilize Wilmington Ave. while they place material on to Area 1? For example: Complete beach fill placement of material on Area 1 before beach fill placement on Area 2.

Answer: Yes, the contractor will be permitted to mobilize in Area 2 while work in Area 1 is ongoing.

2. Will the contractor be allowed to remove material from any of the 5 available borrow areas of their choice without any restrictions?

Answer: No, conform with all restrictions contained in the contract documents. Specification section 35 31 00 paragraph 1.9.2 and drawing sheet

C-401 describe some of the restrictions required.

3. In regard to the Before- and After-Beachfill Surveys, in the specifications, it states "Take surveys profiles at 100-foot intervals at the locations as listed in the tables on the drawings. Survey lines for quantity surveys shall be perpendicular to the seaward edge of berm referenced to the survey baseline." Can you please clarify if the surveys shall be taken at the locations listed in the drawings or perpendicular to the edge of berm.

Answer: The intent is to take survey profiles as they appear on the Before and After Beachfill Cross Sections which are not necessarily perpendicular to the survey baseline. The specifications have been revised to clarify this requirement. See Amendment No. 0001 Paragraph 3.8.2 of Section 01 71 26.

4. Can you please provide the coordinates of the 4 corners of Borrow Area K2?

The drawings show K2 delineated from Borrow Areas K1 and K3, but no coordinates are given. See image below from the project drawings.

Answer: The coordinates for the corners of Borrow Area K2 have been added to the Borrow Area Plan. See Amendment No. 0001 Sheet C-401.

5. In the specifications it states "obtain samples of beachfill material from the finished beach at each project profile line following placement and final grading of beachfill and have them tested for grain size distribution in accordance with ASTM D422." Does project profile refer to the pre- and post-placement survey lines or the Before and After Survey lines?

Answer: This specification refers to the pre- and post-placement survey lines.

6. Clause 52.217-4 and 52.217-5 have conflicting bid evaluation. Please clarify whether the Government intends to evaluate the bids on a Total Base + Option basis or Total Base basis.

Answer: FAR 52.217-4 has been removed from the solicitation. Please see 52.217-5 in the solicitation for bid evaluation.

If topographic surveys are performed separate from wading surveys, develop the composite profile from the wading survey in the region of overlap. If significant differences in elevation between survey segments are observed at locations where segments overlap, submit such information to the District Office for assessment, while still at the site. Significant differences between segments shall be defined as elevation differences greater than 1 foot over a distance of 10 feet or

Section 01 71 23 Page 5 greater along a profile line, and occurring on two or more adjacent profile lines.

3.3 SURVEY CONTROL

a. Survey control descriptions are provided in Appendix A30 and https://rsgisias.crrel.usace.army.mil/apexcrrel/f?p=493:4. Survey the control network utilizing surveying procedures and methodology that meet or exceed accuracy tolerances of +/- 0.10 feet in the vertical and +/- 0.10 feet in the horizontal.

b. USACE-NAP survey control networks are periodically adjusted and updated. This process results in changes to control monuments and coordinates. It does not change the coordinates of the survey baseline.

The survey baseline coordinates and the coordinates of the physical monument may vary. It should be assumed that the survey control network and the survey baseline are independent entities. The physical monument may or may not be on the survey baseline. Establish the relationship between the supplied physical monumentation and the survey baseline.

c. If the name of the survey control point includes stationing or numbers of any kind, the station name should not be assumed to be exact stationing on the survey baselines or profile lines. Coordinates shown on the Survey Control Sheets (DA Form 1959) will govern. Station naming often refers to historic project information and standard calculations must be performed based on coordinates in order to derive the specific relationship between the control point and the survey baseline.

d. Stake and flag all temporary bench marks or control points set within the work limits and clearly label the elevation of the point on the stake.

3.4 SURVEY LOGS

Prepare survey logs in spreadsheet form describing all survey progress and activity for pre- and post-placement condition surveys and for before- and after-dredging surveys.
