End
Background:
The Tiger Hill Soldier Pile Retaining Wall project serves as a second retaining wall on the tiger hill site at the southeast corner of 9th Street and Kenosha, ultimately serving as a supplemental structural support for the existing retaining wall. This retaining wall also acts as a mechanism to facilitate the lowering of the grade of the adjacent project. The City advertised the construction documents on September 25, 2018 and October 2, 2018, and opened bids on October 16, 2018. The contract was awarded to the low bidder, Stronghand LLC. at a contract cost of $1,498,681.24. Notice to proceed was issued to the contractor on January 7, 2019.
This Change Order #2 addresses the following additions to the contract:
CO2-1
As reflected in RFI #4 for the Tiger Hill Soldier Pile Wall project, the existing storm sewer on the east side of the existing retaining wall is in conflict with the proposed soldier pile wall drilled pile. The existing storm sewer line shall be relocated around the conflicting dilled pile to the south with appropriate bends from the proposed new storm manhole around and back to the existing alignment of the storm sewer. The below costs summarize a complete in place product and all applicable mark ups are included.
