ADDITIONAL TECHNICAL QUESTIONS AND ANSWERS

1. From the Amendment 2 Q&A, it is noted that there are several bid items that will be eliminated, and several bid items will have significant quantity changes. Question 91 states to monitor SAM.gov as Section B may be updated via amendment. Should the Contractors expect a revised Section B prior to bids going in on November 13? Below is a list of conflicts/issues if the bid form is not updated:

a. Technical Question 31 states to include cost of sheet pile with cofferdam (CLIN 00010-25) and CLIN 00010-57 will be removed.

i. This is correct. Specifications Section 31 41 16 Measurement and Payment paragraph will be revised to remove sheet pile and will be added to the Measurement and Payment paragraph in Specifications Section 31 03 23 to include the cost of sheet pile in CLIN 00010-25.

ii. CLIN 00010-57 has been removed from the Pricing Schedule. Updated Continuation of Section B in Excel Format – Construction Price Schedule and Updated Solicitation Pages 12-14 have been included as attachments to this amendment.

b. Technical Question 46 states that CLIN 00010-18 quantity should be ~30,000 SF vs the current 6,500 SF.

i. The quantity for CLIN 00010-18 has been revised to 30,000 SF.

ii. Updated Continuation of Section B in Excel Format – Construction Price Schedule and Updated Solicitation Pages 12-14 have been included as attachments to this amendment.

c. Technical Question 54 states CLIN 00010-05 – Concrete Forming does not include incidental forming. However, question 27.c states the government does not dictate means and methods for how forms will be designed/constructed; and question 222 states the forming quantity considers boundaries of concrete placements which required external assistance to hold desired shape. These statements seem to be contradictory.

i. Specifications Section 03 11 10 Paragraph 1.01 A.1 states Include cost of furnishing and constructing forms in applicable prices offered in the Price Schedules for concrete items for which forms are required. All costs associated with formwork shall be included within their respective concrete CLINs.

ii. This supersedes Amendment 0002 Technical Questions & Answers: Questions 27 (a, c, and e), 54, and 222.

iii. CLIN 00010-05 has been removed from the price schedule. Updated Continuation of Section B in Excel Format – Construction Price Schedule and Updated Solicitation Pages 12-14 have been included as attachments to this amendment.

iv. Specifications Section 03 30 00 has been revised to include forming and can be found as an attachment to this amendment.

v. Amendment 0002 Technical Questions & Answers: Question 27c indicated concrete surface preparation costs should be included in CLIN 00010-19 Joint Sealants; however, this has been revised and no longer applies. Please refer to revised Specifications Section 03 30 00 and note all labor and materials costs for concrete placements shall be included within their respective concrete CLINs.

d. Technical Question 27.e indicates the mud mat forming, pouring, and stripping is incidental to CLIN 00010-05 concrete forming. Question 170 states the mud mat will be measured and paid under CLIN 00010-09 Cast in Place Concrete. Question 221 also states the mud mat will be paid under CLIN 00010-09. Please confirm if the mud mat is incidental or will be measured and paid under the applicable unit prices for forming, concrete, etc.

i. Specifications Section 03 30 00 has been revised to separately price the costs associated with the Mud Mat. Revised Specifications Section 03 30 00 can be found as an attachment to this amendment.

ii. This supersedes Amendment 0002 Technical Questions & Answers: Questions 27e, 170, and 221.

iii. All costs associated with the Mud Mat should be included in the newly added CLIN 00010-11 Mud Mat.

iv. Updated Continuation of Section B in Excel Format – Construction Price Schedule

e. Technical Question 119 states Type 2 Rip Rap Bedding is not required.

i. Correct. Specifications Section 31 37 10, Paragraph 1.02 B.1 states “Note that Type 2 Riprap does not require bedding.”

ii. CLIN 00010-55 “Type 2 Riprap Bedding” has been removed from the pricing schedule. Updated Continuation of Section B in Excel Format – Construction Price Schedule and Updated Solicitation Pages 12-14 have been included as attachments to this amendment.

f. Technical Question 125 states the 4” air vent pipe has been eliminated (CLIN 00010-

73). However, question 213.i states that the 4” air vent pipe should be paid under CLIN 00010-73. Please clarify the correct location to measure and pay for the air vent pipe.

i. The 4-inch air vent pipe was accounted for twice in Specifications Section 33 46 36;

Paragraph 1.01. The redundancy has been addressed by deleting Specifications Section 33 46 36; Paragraph 1.01 A and removing CLIN 00010-73 from the Price Schedule. The costs for the 4-inch pipe should go under CLIN 00010-78, Air Vents.

ii. Specifications Section 33 46 36 Paragraph 1.01 has been revised to include an additional CLIN for the 8-inch Diameter Non-perforated HDPE Pipe with a quantity of 54 LF.
