RESPONSES TO QUESTIONS

Responses to Questions:

Grand Isle and Vicinity, LA, Hurricane Ida Repairs, Dune and Beach Construction, Jef ferson Parish, Louisiana

Q1. Note 11 on the 1442 form issued within the Contract Solicitation states that the Contractor shall begin performance within 7 calendar days and complete the work within 400 calendar days after notice of receipt of NTP. Paragraph 52.211‐10 Commencement, Prosecution and Completion of Work on page 43 of the Contract Solicitation states; The Contractor shall be required to (a) commence work under this contract within 10 calendar days after the date the Contractor receives the notice to proceed, (b) prosecute the work diligently, and (c) complete the entire work ready for use not later than 400 after the date of receipt of the Notice to Proceed.

a) The Contractor is requesting the Government clarify which timeline will be applicable for this Contract.

R1. The Contractor shall begin performance within 10 days.

Q2. Due to the complexity of the project, the Contractor is requesting the Government extend the pre‐ bid inquiry deadline for one additional week from the June 6th date as listed on the SAM.Gov project site.

R2. This is addressed by in this amendment.

Q3. Page C‐44 of the Contract Plans displays a drawing showing the maximum allowable dig depth as ‐ 16’ in the Barataria Borrow Pit. Note 3.1.4 Borrow Dimensions on page 7 of Section 35 20 23.00 12 states; An allowable tolerance of one (1) foot above the dredge bottom cut elevation of ‐20.0' NAVD88 shall be allowed.

a) The Contractor is requesting the Government clarify what the maximum allowable dig depth will be.

R3. Note 3.1.4 Borrow Dimensions on page 7 of Section 35 20 23.00 12 shall be revised to “An allowable tolerance of one (1) foot above the dredge bottom cut elevation of ‐20.0' NAVD88 at the Caminada Borrow Pit and ‐16.0’ NAVD88 at the Barataria Borrow Pit shall be allowed.”

Q4. Section 2.1.1 of the Technical Specifications states "Suitable clay materials are defined as ML, CL, and CH as per the Unified Soils Classification System, subject to the limitations of paragraph, Moisture Control". Section 01100‐General Provisions, sub‐section 15 provides a list of lands containing clay sources that may be capable of producing the quality of clay material meeting requirements set forth above. It further states "The contractor is responsible for submitting a complete borrow submittal for Corps review and approval with all applicable updated documentation. See Section 31 23 00.00 12 EXCAVATION, paragraph entitled, Submittal Package Requirements in Detail." There is no section as such in the EXCAVATION technical specification. Is it to be understood that the clay material can thereby come from a source outside of those listed in sub‐section 15, CLAY SOURCES, so long as that material is classified as ML, CL or CH? Will a borrow pit submittal package still be required? If so, can specific requirements of that package be provided?

R4. See revised edits to the specifications.

SECTION 00010 - SOLICITATION CONTRACT FORM

The required response date/time has changed from 27-Jun-2023 10:30 AM to 29-Jun-2023 01:30 PM.

The contractor period of performance begin date has increased by 3 days from 7 days to 10 days.
