MILLER INTER -OFFICE MEMORANDUM DEPARTMENT OF PUBLIC WORKS DIVISION OF ENGINEERING TO: Theresa Heffner, Clerk Board of Public Works FROM: Becca Plantz, Project Engineer SUBJECT: Change Order 3 Project No. 119-011 DATE: August 11, 2023 This contract was originally awarded as an open market contract after being opened first on November 9, 2021. The open market contract was awarded on April 26, 2022, and owner direction was provided to wait until after the summer season to shut the plant down. Additional field orders from the owner and research for discussions to finalize requests for information support the reason for extending the substantial completion to October 31, 2023, or scope complete to the point that the plant can come back on in this time. Field orders and RFIs resulting in delay include replacing manways on each vessel per R-Stamp standards, applying to be removed from the state registered list of vessels prior to repairs, and filter clarifications on pre -conditioned media. The final completion is being set for November 30, 2023, to encompass discharge water head pipe replacement. The increase of this change order in the amount of $5,687 is a net total of field orders and savings found in the allowances and unit price items. Increased costs are associated with the need to replace the hatches on each vessel, the testing required for this level of replacement, repair and replacement of the degrading discharge head in the upper level, and a support gravel size change during media placement. The physical rehabilitation of the vessels is nearing completion with less structural concerns encountered than prepared for, resulting in savings identified in the allowances and unit prices designed for this scope.
