RESPONSES TO QUESTIONS:

*Questions are continuous amoung all amendments

16. Question: Plan sheet D-505, detail 5 is the seal plates for the stop logs. Can more details be given on the gusset size and spacing as well as the anchor bolt spacing?

Response: This is to be contractor designed.

17. Question: Please provide the Government’s estimated quantities for job items.

Response: See attached job item quantities.

18. Question: How is the removal and disposal of muck from the required backfilling of the existing Mississippi Bayou and temporary Mississippi Bayou measured and paid?

Response: No separate measurement and payment will be made for mud/muck removal.

Payment for mud/muck removal shall be included in the contract item for which the work is incidental thereto.

19. Question: Please provide specification section for the electrical work required on plan sheet E- 001.

Response: Section 35 20 16.54 Slide Gates and Hoist.

20. Question: When will we receive the results from the “sister pile load tests” per response no. 5 in amendment 1?

Response: The sister site for WSLP 108 is the Reserve Relief site. Pile driving is underway but no testing has been performed yet, our estimate is 2-3 months for results.

21. Question: Section 31 62 16.16 -3.3.1.1 states only 2 test piles (hp14x73) will be subject to PDA monitoring, but the response to question 4 states a total of 4 PDA test piles please clarify.

Response: There should be 2 PDA test piles per pile depth, for a total of 4. The specification will be revised to clarify this.

22. Question: Addendum 0001 reduced the contract duration to 854 calendar days. Specification section 00010, note 7 provides 36 calendar days for OW1 and 188 calendar days for OW2.

Please confirm that if optional work is awarded, the total contract duration is 1,078 calendar days and not 854 calendar days.

Response: Yes, if both options are awarded the contract duration will be 1,078 calendar days.

23. Question: There are currently four West Shore projects solicitations, two bidding at the same time on 8/1, one bidding on 8/8, and one bidding on 8/9. Three of these projects are small business set-asides. Please consider spreading these projects out, where only one bids a week.

This would allow small businesses to be more competitive on all of the West Shore projects and provide the Government a lower overall project cost.

Response: Please see this SF30.

24. Question: Will the contractor be allowed payment for material stored offsite on h-piles, sheet piles, slide gates, stop logs, and the permanent precast concrete bridge?

Response: H-piles and sheet piles can be stored off site. The remainder cannot. Specification

Section 01100 will be revised.

25. Question: Specification section 01 53 00.02 12, paragraph 2.1 states “The sheet pile shall be hot rolled sheet pile as defined in Section 31 41 16.00 12 Steel Sheet Piling”. Are the temporary retaining structures sheet piles required to be new in accordance with section 31 41 16.00 12?

Response: This should be per the licensed engineer of record. However, the sheet piles shall be hot rolled.

26. Question: Drawing C-403 depicts 9 each 5’ diameter culverts at the existing temporary bypass canal culvert crossing which is required to be removed by this contract. The WSLP-107 project consisted of 10 each 5’ diameter culverts. Please clarify and provide an updated drawing so the items to be removed can be accurately determined.

Response: The drawing should show 10 each 5’ diameter culverts to match WSLP-107. The revised sheet C-403 is attached.

27. Question: Will the existing base for the temporary bypass canal culvert crossing consisting of the sand, limestone, and geotextile be required to be removed along with the culverts, which will require dewatering?

Response: Yes.

28. Question: Please provide a breakdown of all lump sum CLINs.

Response: See attached job item quantities.

29. Question: We request a bid opening extension.

Response: Please see this SF30.

SECTION 01100

Page 28. At the end of paragraph 33, add the following new paragraph as:

"34. PAYMENT FOR MATERIALS STORED OFFSITE

Pursuant to the FAR clause 52.232-5, PAYMENTS UNDER FIXED PRICED CONSTRUCTION CONTRACTS, materials delivered to the Contractor at locations other than the site of the work may be taken into consideration in making progress payments if included in invoices for payment estimates and if all the conditions of the Contract Clauses are fulfilled. Payment for items delivered to locations other than the work site shall be limited to materials that have been approved (if required by the Technical Specifications) and fabricated to the point where they are identifiable to an item of work required under this contract. Such payment shall be made only after receipt of paid or receipted invoices or invoices with canceled check showing title to the items by the prime contractor. These invoices must show the dollar value of the materials and labor incorporated into them. The delivery size shall be acceptable to the Government and the materials shall be available for inspection by the Government prior to any consideration for payment. Refer to FAR clauses 52.232-5 PAYMENTS UNDER FIXED-PRICE CONSTRUCTION CONTRACTS, and 52.236-7 PERMITS AND RESPONSIBILITIES regarding the Contractor’s retention of risk and liability for any loss or damage prior to incorporation of materials into the permanent work and acceptance. Payment for materials delivered offsite is limited to the following items: H-piles and sheet piles."

SECTION 31 62 16.16

Page 15, subparagraph 3.3.1.1. Delete this subparagraph in its entirety and substitute the following, therefore:

"3.3.1.1 Dynamic Pile Analysis

Submit a Pile Performance Report summarizing dynamic test results for test piles within 5 calendar days of completing field work.

Dynamic testing provides supplemental information for evaluating pile integrity, hammer and drive system performance, assess pile installation driving stresses, and pile capacities. dynamic testing will validate the dynamic testing results previously performed for the production piles at the Reserve relief canal location located at Northing 585150, Easting 353125. These results may require adjustments to the pile lengths. The pile load testing at the Reserve Relief canal included both static and dynamic load tests with the results used to determine the pile bid quantities. There will be two PDA tests per pile depth for two depths, resulting in four total PDA test piles. For estimating purposes assume the piles will be driven to el. -83 and to el. -73 at the locations indicated. The actual PDA test pile tip elevations will be based on the results of the pile load test program currently in progress. Perform dynamic testing on the HP14X73 test piles during the full length of the pile driving and during restrike a minimum of 14 days after initial driving. Upon completion of testing, the test piles can be pulled and reused as production piles provided that they are cleaned, painted and are in satisfactory condition as determined by the Contracting Officer's representative. Provide equipment to obtain dynamic measurements, record, reduce and display its data that meet the requirements of ASTM D4945. The equipment must have been calibrated within 6 months prior to the start of the testing operations and thereafter throughout the contract duration. Drive test piles at the locations indicated or at the locations selected by the Contracting Officer. Employ an independent inspection firm, hereinafter referred to as the Contractor's Geotechnical Consultant, experienced in the pile driving process, monitoring of test pile installation, and in the use of the Pile Driving Analyzer and its related equipment. Perform dynamic pile analysis as follows:"

**The unit "JOB" as used in this Bidding Schedule is synonymous with the term "Lump Sum" used elsewhere within these plans and specifications.

Award will be made as a whole to one bidder.

NOTE 1: Bidders shall furnish unit prices for each item listed in the Schedule requiring a unit price. If the bidder fails to insert a unit price in the appropriate blank for required item(s), but does furnish an extended total, or an estimated amount for such item(s), the Government shall deem the unit price to be the quotient obtained by dividing the extended amount for that line item by the quantity.
