On November 17, 2020, City Council awarded the Ridge Creek Park and PLOC Improvements Project PR-20-001 to Frattalone Companies. Frattalone Companies started in late January of 2021 to construct the new alignment of the Prior Lake Outlet Channel (PLOC), storm sewer, wood boardwalk and a bituminous trail.

Subsequent to the consultant's estimating of quantities that occurred during the design phase of this project, quantity and design errors were discovered in multiple bid items. These errors were not discovered prior to bidding and were not fully known until after construction was complete and quantities were measured in the field. The overrun quantities for the identified bid items would have been needed regardless of what the estimated quantities were on the bid tab and are being paid at the original bid unit prices. Likewise, the additional costs experienced would have been realized regardless with little to no cost savings expected if the original quantities would have been correct.

All work on the project has been completed and the attached Change Order 1 includes the additional quantities above the contract amounts for specific bid items (see attached Change Order 1). A summary of the work as part of this change order includes additional quantity for common excavation, subgrade excavation, select granular borrow, helical piles and riprap. These items were needed to construct the new channel alignment, the wood boardwalk, and the bituminous trail.
