Memorandum
Attached for your review and approval is a resolution to award a construction contract to Front Range Environmental LLC in the amount of $1,079,000.00 for the Sanitary Manhole Rehabilitation Project.
The Sanitary Manhole Rehabilitation Project will consist of making various repairs to approximately 300 sanitary manholes. Many of the manholes are in flood prone areas and the repairs will reduce the potential for water inflow and infiltration (I/I) to the sanitary sewer system. The repairs include a variety of methods to reduce I/I and increase the longevity of the manholes, such as installing new solid covers, replacing/repairing the top section of the manholes, and waterproofing the interior or exterior of manholes. This work follows up on one of the recommendations that came out of the City's Sanitary Sewer Wet Weather Evaluation Project.

Three bids were received and opened on May 23, 2018. The lowest responsive bid, from Front Range Environmental LLC in the amount of $1,079,000.00 is 50% higher than the Engineer's Estimate.

Attached is a summary of the bids received for the project.
