QUESTIONS AND ANSWERS

Questions and Answers updated 9/6/2024

QUESTION 1: Note 7 on the bid schedule states that Bid Item 0005 is excluded from the Variation in Estimated Quantity clause. However, the clause states that it applies to item Nos. 0002, 0003, and 0005. Please confirm that Bid Item 0005 is included under the clause.

RESPONSE 1: Inclusion of CLIN 0005 in note 7 is in error. Note should only apply to CLIN 0006. Note is revised with this response to read, “The quantity shown in Item 0006 is for evaluation purposes only. Payment for this line item will be based on the actual quantity used and it shall be excluded from the clause FAR 52.211-18, “VARIATION IN ESTIMATED QUANTITY.”

QUESTION 2: What is the date of last dredging for Bayou Black Sta. 4+00 to 96+00? Please also provide dredging dimensions.

RESPONSE 2: Based on Contract 88-C-0155., The limits of dredging were non-continuous. Work included Station 9+00 C/L to Station 158+00 C/L and from Station 205+00 C/L to Station 251+89.62 C/L Bayou Black - GIWW.

Channel width was 400 feet with dredging to elevation (-)22.0ft MLG with overdepth at (-)24.0ft MLG.

QUESTION 3: What is the date of last dredging for Bayou Boeuf Sta. 4+00 to 96+00? Please also provide dredging dimensions.

RESPONSE 3: Based on Contract 88-C-0155., The limits of dredging was Station 2+00 C/L to Station 96+00 C/L on Bayou Boeuf; The contract involved dredging a 400 foot wide channel to an elevation of (-)22. 0ft MLG and an allowable overdepth to (-)24.0 ft MLG in all the reaches of work except in the upper portion of Bayou Boeuf from Station 2+00 to Station 65+45. In this reach the channel width was 300ft wide and widening to 400ft wide in curves up to Station 95+22. The elevation remained at (-) 22.0ft MLG with overdepth at (-)24.0ft MLG.

QUESTION 4: Section 35 20 23 Paragraph 3.3.1.2 and Note 3 for Plan Sheet C-06 state that material shall be placed in Penchant East and West to a minimum elevation of +6.0 ft NAVD88. Does the Government intend for material to be placed to a minimum elevation of +6.0 ft or a maximum elevation of +6.0 ft?

RESPONSE 4: Material shall be placed in Penchant East and West to a MAXIMUM of +6.0 ft NAVD88.

“Minimum” was in error.
