AMENDMENT 0002

Requests for Information (RFI) Responses for Poplar Island, 2019 Expansion Structures Project

12-JUL-2019

Question 001: In regards to the seepage cut-off blanket, sheet C-501 state the #57 stone is existing but there is no mention of the existing #7 stone. Sheet C-202 shows that the existing dike section consists of #57 and #7 stone with top of gradation elevations higher that the final grades for the same stone shown on C-501. It is intended for the contractor to excavate the #57 stone to contract grades, excavate, stockpile, and reuse the #7 stone, and procure, deliver and install the #10 stone?

Response 001: Note #2 on sheet C-501 should state #7 stone and #57 stone are existing. As the commenter has pointed out, #7 stone and #57 stone are shown on sheet C-202 as existing conditions. The contractor shall excavate the existing #7 stone and #57 stone to the extents needed to execute this contract. The #57 stone may be reused as the drainage layer for the block wall if allowed by the designer. Excess #57 stone shall be stockpiled at the southern bulkhead.

The #7 stone shall be stockpiled and reused as part of the seepage cut-off blanket. Excess #7 stone shall be placed at the southern bulkhead. There is no #10 stone existing at the locations of these structures.

Please see attachment 1 for the updated drawing for sheet C-501.

Question 002: Please provide the existing, or most current, embayment bathymetry so the contactor can determine if the project site is accessible by floating equipment. The typical spot soundings provided on C-101 may not be indicative of the ingress alignment through the break waters or the surrounding area which may have been impacted by recent construction activities.

Response 002: Please see attachments 2 and 3 for the latest embayment bathymetrical survey.

Question 003: Will the government allow a panel type MSE retaining wall as an alternative to the suggested wet cast gravity block wall shown in detail 2 on sheet C-501?

Response 003: Contractors shall bid per the plans and specifications as a gravity wall.

Item #4 – Updated two notes each on sheets C-101 and C-102. They referenced sheet C-701, which was changed to sheet C-201.

Item #5 – Updated sheets GI001 and C-301 to use the same title.

SECTION 00 10 00 - SOLICITATION

The required response date/time has changed from 16-Jul-2019 11:00 AM to 23-Jul-2019 11:00 AM.
