Specify type of business, Small Business Category (if any), UEI Information and if you would like to participate as a Prime or Sub-Contractor.

The Government is requesting answers to the following technical questions:

1. Can you describe your current sheet pile installation equipment types and if the equipment can meet the Press-In method of installation requirements?

Contractor answer:

2. The sheet pile will require significant embedment into a hard limestone layer. We are requiring pre-auguring to break up the limestone and allow for sheet pile placement; however, the existing bulkhead panels and soldier piles are in close proximity to the auguring and embedded into the same limerock layer. To minimize the risk of failure of the existing bulkhead during the auguring process, positioning of the auguring system and minimizing the time between the auguring of the rock and placement of the sheet pile will be important. Can you explain how and what type of equipment you would use to accomplish the pre-auguring?

Contractor answer:

3. The area between the new sheet pile and the existing bulkhead will be filled with CLSM, in sections, and lifts, the ends of each segment will need seals placed to prevent the CLSM from flowing into the basin. Can you explain your approach to sealing the segments to allow for CLSM to be placed?

Contractor answer:

4. As the CLSM is placed, turbid water will be displaced, if turbidity barriers do not provide sufficient protection, how would you propose meeting the turbidity requirements?

Contractor answer:

5. Do you believe baker tanks and or filtering equipment will be required to treat the displaced water if the turbidity requirements cannot be maintained?

Contractor answer:

6. For architectural and corrosion prevention reasons a precast façade is to be mounted in front of the sheet pile. This precast concrete façade will extend from the top of the wall to below the mean low water elevation. The gap remaining between the façade panel and the sheet pile is to be filled with CLSM, how would you seal this gap at the bottom and sides to prevent CLSM from flowing into the basin?

Contractor answer:

7. As stated above, the vertical and horizontal tolerances associated with the sheet pile placement are tight to allow for façade panel placement and maintain the architectural look of the bulkhead. Can you explain how you propose to maintain these tolerances throughout sheet pile placement?

Contractor answer:

8. Several outfall pipes will penetrate the existing wall. These outfall pipe will need to be extended through both the new sheet pile and the concrete façade panels; can you describe how you would accomplish this?

Contractor answer:

9. Various protected and potentially dangerous species and fauna populate the project site. Can you describe any experience you have working in highly environmentally sensitive areas and how you will handle the environmental restrictions that are required by this project?

Contractor answer:

In consideration of the above factors and any others which may be deemed appropriate, the construction community is invited to comment on the use of PLA's as part of the Government's market research. The Government is requesting responses to the following questions:

1. Do you have knowledge that a PLA has been used in the local area on projects of this kind? If so, please provide supporting documentation.

· Project Name and Location

· Detailed Project Description

· Initial Cost Estimate vs. Actual Final Cost

· Was the project completed on time?

· Number of craft trades present on the project

· Were there any challenges experienced during the project?

Contractor answer:

2. Are you aware and/or are there concerns by the prime contractors of skilled labor shortages in the area for those crafts that will be needed to complete the referenced project? If so, please elaborate and provide supporting documentation. Information may reference current apprenticeship statistics and workforce age demographics.

Contractor answer:

3. Are you aware of time sensitive issues/scheduling requirements where use of the PLA would affect the rate at which the referenced project would be completed? If so, please elaborate and provide supporting documentation.

Contractor answer:

4. Are you aware of any cost impact where the use of PLA will affect the construction cost of the referenced project? If so, please elaborate and provide supporting documentation.

Contractor answer:

5. Based on FAR 52.222-33 and alternates and 52.222-34 and alternates do you see any negative and/or positive impacts of submitting the PLA at one phase of the procurement process over another? If so, please explain. Also, provide an estimated and realistic timeframe that your company will be able to finalize a PLA.

Contractor answer:

6. Identify specific reasons why or how you believe a PLA would advance the Federal Governments interest in achieving economy and efficiency in federal procurement.

Contractor answer:

7. Identify specific reasons why you do not believe a PLA would advance the Federal Governments interest in achieving economy and efficiency in federal procurement.

Contractor answer:

8. Identify any additional information with supporting documentation/statistics that you believe should be considered on the use of a PLA on the referenced project.

Contractor answer:

9. Identify any additional information with supporting documentation/statistics that you believe should be considered on the non-use of a PLA on the referenced project.

Contractor answer:

10. Is your firm a serious interested party in that you intend to submit a proposal for this procurement? Will the use of a PLA impact your ability to bid? If so, please explain?
