Question 5. The specification state, “Proceed with the placement of the beachfill in a continuous manner along the shoreline moving generally east to west, starting at Beach 9th Street, or as directed by the COR.”

Due to the Time of Year Work Restrictions along with the December 1, 2022 completion requirement, this requirement will greatly limit the sequencing of potential dredging Contractors and will force the work to be done in less favorable weather conditions. In order to provide the best value for the Government, we would like to request that Contractors be able to define their order of work and commence in the western portion of the project if deemed beneficial.

Response: Beachfill deadline extended to March 14, 2023. Sand placement must be east to west along the shoreline, the starting point is flexible if deemed beneficial to start elsewhere.

RFI SET #8:

The following questions reference Rockaway Contract 2 Specification Section 32 94 00

Question 1. Paragraph 1.2 Area to be Vegetated, identified the Beach grass quantity of 13552 culms, however a quantity of 4840 plants without a description of if the word plants, units and/or culms. Please define and clarify if Plants refers to goldenrod, beach rose, bayberry, and beach plum, or if it is inclusive of beach grass and should be added to 13552.

Response: The numerical number presented in the spec are just a reference number of plants per acer depending on the requested spacing of the plants which ranges form 18-36 inch on center. The plant species are reference in the spec to define the plant spacing.

Question 2. Paragraph 2.1 Plant Material Cape American Beach grass quantifies 19,360 planting units per acre. Please clarify if this language is interchangeable with culms, and the term “plants” utilized in paragraph 1.2.

Response: Yes when the word plant refers to Beach grass.

Question 3. One acre in Paragraph 1.2, adding 13,552 culms with 4,840 plants, equals 18,392.

One acre in Paragraph 2.1 indicates 19,360 planting units of Only Beach grass.

Manual counting of beach grass in the “enclosed basic planting plan” as referred to in 1.2, and as shown on the last page of 32 94 00, provides a quantity of 14,794 per acre.

All bold numbers were within 32 94 00.

Please advise the intent of the quantity of beach grass on this project per acre.

Response: The intent is to plant beach grass 18 in oc. The total numbers per acer are just for reference.

Question 4. 32 94 00 Paragraph 1.2 describes species locations and refers to a planting plan. Both conflicts.

Scenario 5 plants South side:

- beachgrass Crest:

- goldenrod

- beach rose

- beach grass

North side

- beach grass

- bayberry

- beach plum

Conflict:

Planting plan shows 6 plants and introduces Sumac (also does not specify type of species), all plants appear on all sides of dune, not isolated as described above to sides of the dune.

Response: The figure is just an example of the planting scheme; plant sumac specifications were added to section 32 94 00.

Question 5. Please advise layout of crest, and layout of Northside if the intent is not the planting plan provided within spec 32 94 00. Also advise where Sumac is to be planted if the intent is not to utilize the provided planting plan. Additionally, please provide the species of Sumac.

Response: Sumac specifications added to section 32 94 00.

RFI SET #9:

Question 1. Upon review of the plans, there are cross sections that show the new reinforced dune, then the dune berm that goes out at elevation 8, approximately 240’ from the baseline depending on location.

Then there is a note at the bottom of the plan stating “ 3 FILL AREAS WHERE EXISTING GRADE IS

ABOVE THE DESIGN TEMPLATE, THOSE AREAS SHALL NOT DISTURBED. THESE AREAS SHALL

BE VERIFIED WITH SURVEY ON FIELD BY THE CONTRACTOR”. Is it up to the contractor to assume that any area after the dune crest at elevation 18 that is higher than the proposed grade that we are not going to touch it? It is not really clear with having that note, but still showing a proposed grade line that is below the existing grade line. It also makes excavation difficult to attempt to not damage any existing dune that is above the proposed grade location outside of the immediate work area. Also how are the As-builts going to be accepted? Will they be accepted based on proposed grades or based on the preliminary survey grades that were taken?

Response: Contractor to place fill between existing beach and proposed template, and not disturb sand above the proposed template. This only applies for fill, and not for the excavation required to construct the reinforced dune. After the construction of the reinforced dune, sand shall be placed to the proposed template. Refer to section 01 22 00.00 10 Price and Payment Procedures for as-builts/acceptance/payment/measurement.

Question 2. For timber pile driving the testing requirements and quantities were not specified. Is PDA testing acceptable? What quantity of piles required testing? Please advise, thank you.

Response: PDA testing is acceptable and shall be performed on 14” diameter piles supporting the ends of the truss span. Clarifying notes will be added to the structural drawings and specification section 31 62 19 will be revised to include testing requirements in the next Amendment package.

Question 3. Just received Addm #3. . please look at the files that end with .txt all look like IP Addresses?

Please advise.

Response: All the .txt files provided in Amendment 3 are XYZ survey data for the beach placement area and borrow areas. The .txt file is just easting (x), northing (y) and elevation (z) coordinates.

RFI SET #10:

Question 2. Amend 3 -Question #6- Does the response infer a separate NTP for the dredging contractor?

As opposed to the prime contractor? Please clarify?

Response: Only the prime contractor will receive NTP.

Question 3. Section 01 14 00 Work Restrictions- 1.3.1 Order of Work references “Hydraulic beachfill placement must be constructed prior to reinforced dune and crossover construction, and base hydraulic fill must be completed by December 1, 2022”. The date has changed (per Amend 3), however is the order of work mandatory. Will the USACE consider reinforced dune construction starting before Hydraulic beachfill commences?

Response: Yes, pending work plan/contractor’s schedule approvals and if contractor adheres to specification requirements, such as, but not limited to, the following specifications -

Section 31 23 00.00 20 par 1.5 c - Suitable backfill in the quantities required is not available at the project site; hydraulic fill from borrow area is needed in addition to material on site.

Section 35 31 29.40

3.13 ACCEPTANCE SECTIONS

3.13.1 Section Designations

Completed work on the rock reinforcement shall be accepted in 100-foot sections. The accepted sections may be backfilled to its design dune grade with sand. Dune reinforcement shall not be left exposed without backfill for lengths greater than 500-feet.
