On December 12, 2023, the Village Board awarded a contract for rehabilitation of several thousand lineal feet of Asbestos Cement Sanitary Sewer pipe to Performance Pipelining Incorporated (PPI) for a bid amount of $204,248.75. The project received advantageous pricing from PPI, as the bid amount was significantly under the budget amount of $340,000. Due to the available budget remaining in the project and the favorable pricing included in the bid award, Engineering and Operations staff worked with the Village's construction engineering consultant, RJN, and PPI to identify options for additional services to add value to the rehabilitation project.
The original scope of work consisted of lining of sewers upstream of the Bode Road sanitary lift station. In order to line these pipe segments, the flows from the lift station had to be rerouted via bypass pumping, so the lines could be cleaned prior to lining. When the PPI crews began preparations for installation of a new manhole on the existing force main, it was discovered that the force main was in the pavement of Aimtree Lane and not in the parkway as expected and proposed an additional $4,543.60 for traffic control and pavement restoration.
The original bid for the project included the installation of grout to secure all lateral services. PPI provided a proposal for $31,640 to install t-liners rather than grout, which provides a more secure connection. In addition, PPI provided proposals totaling $67,224 to line additional pipe segments totaling 752 lineal feet, which included additional lateral t-liners on the pipe segments and an additional frac tank to accommodate the extra flows during bypass pumping.
In total, PPI provided proposals in the amount of $103,407.60 for additional services associated with the project.
The Village's Capital Improvement Program has budgeted funds in FY 24/25 to construct these improvements. Due to advantageous bids, the project does have available funds to pay for the additional proposals from PPI.
