Res 24-421 Approve CIP Amendment and Award Bid for Public Works Contract No. 24-11 to Vinton Construction Company for Sanitary Manhole Rehabilitation / Inflow/Infiltration Reduction Program ($950,664)

BACKGROUND

The purpose of this Project is to repair and upgrade existing sanitary sewer manholes to reduce the amount of inflow and infiltration entering the sanitary sewer system. Engineering staff have previously inspected sanitary manholes to identify any defects. This Contract will perform necessary repairs to approximately 125 of the approximately 5,800 public sanitary sewer manholes. This work will begin in the fall of 2024 and be completed by the spring of 2025. Upon completion of this Project, approximately 2,125 manholes will have been rehabilitated since 2010.

ANALYSIS

Engineering staff reviewed the three (3) bids that were received. The low bid was received from Vinton Construction Company of Two Rivers, Wisconsin. The total bid is $950,664.

FISCAL IMPACT

Funding for the Sanitary Sewer portion and a portion of the Storm Sewer portion of this Project is available in the Capital Improvement Program (CIP) (Account No. 03210410-6802-04011/Contract Control-Sanitary Sewer-Annual – I & I Sanitary Swr Rehab and 03210410-6804-04011/Contract Control-Storm Sewer-Annual – I & I Sanitary Swr Rehab).
