Title
NW Friberg and Goodwin Street Improvements
Details: Change Order No. 3 for project S-566 NW Friberg and Goodwin Street Improvements includes 13 additional required items totaling $68,732.37, to the Contractor, McDonald Excavating, Inc. These items include an upgrade to the electrical service for the traffic signal, installation of over 15,000 square yards of geotechnical fabric to reinforce the underlying subgrade, the relocation of several utilities to accommodate a traffic signal pole, installation of irrigation piping not shown in the plans, extra saw-cutting above the bid quantity, and additional gabion rock, pipe fittings, and other miscellaneous items outside the scope of the original bid. A more detailed explanation of these additional items is provided on the attached change order. Also attached is a funding memorandum with the updated expenditures for the project. While the change orders total approximately $156,000 or 3.8% of the original contract amount, the bid item overruns will total approximately $291,000. The majority of these bid overruns are due to an underestimated amount of flagging time and the overexcavation and backfill of unsuitable roadway base. The overall additional costs above the bid items is nearly 10% of the original construction bid awarded. Payment for the additional cost of this project will be proposed as part of the general obligation bond to be presented to Council by the Finance Department.
