Project PRA-NATR 1E10 Natchez Trace Parkway

Little Swan Creek Bridge Replacement Big Swan Creek Bridge Repair

Solicitation: DTFH71-15-B-00005

The purpose of this Amendment is to:

1) Revise the Plans to replace Sheets R17 and R28.

2) Provide two precast manufacturing plants for informational purposes only.

3) Provide a summary of responses to questions/clarifications asked by potential bidders.

4) Reschedule the Bid Opening date to April 21, 2015, at 2:00 p.m.

Plans changes

Delete Plan Sheets R17 and R28, and substitute the amended Plan Sheets R17 and R28.

1) Sheet R17 updated to provide additional detail and bars required for the overhang.

2) Sheet R28 updated to provide additional bar for the bar list.

Questions / Clarifications

The following questions and issues were submitted to EFLHD at eflhd.contracts@dot.gov. The Government response or clarification is provided. Due to the repetitive nature of several questions and issues, the wording of the questions may have been revised and some questions have not been included. The Government’s direct response to the sender may also have been updated below for better clarity.

1. The project was originally advertised on 2/06/2015, readvertised on 4/6/2015, and then rescheduled the bid opening date to 4/16/201. This leaves only a period of 10 days from readvertisement to bid opening for review and response. Can this period be extended to allow a minimum of 14 days for review and response?

Response: The bid opening date will be extended to April 21, 2015.

mailto:eflhd.contracts@dot.gov

Info Page 2 of 2

2. Since the bid opening was temporarily suspended, will the original bid proposal be acceptable or will a new bid proposal be required?

Response: The original bid proposal is acceptable if prices do not change from any amendment information.

3. The Little Swan Creek Bridge, Schedule A, does not provide enough reinforcement detail for the cast-in-place overhang on Section B-B, pages R17. For clarity, can you provide a detail for the cast-in-place overhang?

Response: Plan Sheets R17 (Deck Panels) and R28 (Bar List - 4) will be revised by amendment to clarify the requirements.

4. Amendment No. 3 has answered to load restriction regarding the hauling of the little Swan Creek Bridge precast units but does not address construction equipment. Cranes, and other equipment, needed to off load and erect the precast units, construct access roads and temporary structures will exceed the load rating by themselves, not including the trucks and trailers needed to mobilize the equipment. Will the load restrictions on the Natchez Trace Parkway be waived in order for construction equipment to mobilize the site(s)?

Response: Load restrictions on the Natchez Trace Parkway do not apply for the hauling of Little Swan Creek Bridge precast concrete units only. Load restrictions on the Natchez Trace Parkway do apply for the hauling of all other materials.

5. Addendum #3 has answered that two precast plants in TN exist that have the ability to perform the work. Can the contact information for the two TN precast manufacturing plants that will be quoting the precast components be provided?

Response: Two precast manufacturing plants are provided with this amendment for informational purposes only.
