Former Adirondack Steel OU-2 and OU-3 Remedial Action Contract No. D010731 Section A: Changes and Additions
• Item 1 REPLACE Sheets 18 through 26 of the Contract Drawings with corrected sheets provided in Attachment A.
Section B: Questions, Answers, Clarifications The following provides answers to the substantive questions received by the New York State Department of Environmental Conservation (Department). Where appropriate, similar questions or questions related to the same subject were combined to streamline the Questions and Answers and reduce redundancy. The Bidders must thoroughly review the bidding documents and not rely solely upon answers provided to questions during bid preparation and during implementation of construction activities. Q1. The color identifying the type 1 and type 2 materials changes throughout the design drawings.
I’m starting to question which color on which sheet to the correct one. For example, please compare sheet 9 of 28 to sheet 18 of 28. Please advise if this can be corrected prior to the bid date.
A1. Identification of Type 1 (Non-TSCA) and Type 2 (TSCA) excavation areas on Sheet 9 of 28 is correct. The discrepancy noted in the question is due to an error with the legend identification on profile views in Sheets 18 through 26 of the Contract Drawings. Color coding of excavation areas between the plan view and profile views is correct, identification in the legend as to which type represents Non-TSCA and TSCA areas was corrected. Please see Item 1 in Section A of this Addendum No. 3
Q2. The project bid form includes the item UP-4 – Excavation Support, 5,610 Square Feet. This
quantity appears to be derived from the John P. Stopen Engineering design, detailed by the “Sheet Pile Enclosure Example”, Sheet No. #7, dated February 10, 2020, provided by the EA “Request for Provisional Approval of Conceptual Excavation and Shoring Plan Letter Report”, which appears to be the quantity for the full height of the suggested steel sheets, per the provided details. Yet, the project provided Section XII – Measurement for Payment, page XII-15, subsection 3.11.B.2 states: “… measured as the area of exposed face in the plan of the shoring system from the ground line in front of the shoring to a maximum of one foot above the retained grade.” This measurement would create an exceptionally lower quantity of excavation support to be measured and paid, versus the provided bid quantity, which would have varying implications as to how the bidding Contractor prices this work. Could the Department please verify the bid quantity versus the measurement for payment for item UP-4, Excavation Support?
A2. Please bid as specified using the quantity provided on the Bid Form.
This ADDENDUM No. 3 becomes part of the June 2021 Former Adirondack Steel Contract Documents D010731.
