SUBJECT:
Resolution to Reject All Bids for the Lakeview Drive Storm Sewer Repair project for the Engineering Division.
PURPOSE:
To obtain City Council approval to Reject All Bids for the Lakeview Drive Storm Sewer Repair project for the Engineering Division.
BACKGROUND:
In fall 2017, the Water & Sewer Maintenance division was notified of a sink hole in the rear yard of 145 Lakeview Drive on the bank of the lake. Upon inspection, it was determined that the sink hole was located over a 60" corrugated metal pipe (CMP) that extends into the lake approximately 10'. In addition to the sinkhole, the visible portion of the 60" CMP in the lake appeared to be failing and in a hazardous condition. Original design drawings for the storm sewer were located which showed that the majority of the pipe run was constructed with 48" reinforced concrete pipe (RCP), but the last 40' of the pipe run was constructed with 60" CMP. With the normal water of the lake over the top of the 60" CMP the exact location of the pipe transition could not be confirmed.
DISCUSSION:
The contract to perform the work was advertised on June 10, 2018 and bids were opened on June 27, 2018. Three bids were received.
The lowest bid received was for $73,630.00 which was to cover the replacement of the deteriorated 60" CMP.

The City did not take this approach initially because it would mean dewatering the lake for inspection and again for construction which would most likely frustrate the property owners around the lake. Once the lake was dewatered for inspection, it was found that the 60" CMP requiring replacement was short...
