Mr. Roberts explained that it is a piston engine and the gas would be very corrosive if it was not treated and this project is to clean the gas. The technology has improved significantly and this will provide a good life expectancy of the equipment. |

Moved by Councilmember Jamie Whelan, seconded by Councilmember Jim McCarthy to approve the contract with PCL Construction, Inc.("Contractor") in the amount of $1,067,535.00, which includes a contract allowance of $50,835.00 and a contract time of 365 calendar days and authorize the City Manager to execute the necessary documents. Councilmember Odegaard asked if there is a rough estimate for Phase 2. Mr. Roberts stated that it will run approximately $600,000 for the engine and installation. Councilmember Aslan asked about the life expectancy of the engine. Mr. Roberts stated that it is 20 to 25 years if properly maintained. The existing engine had a lot of problems operating in the room and one of the other things included in the project is to add better ventilation and airflow to prevent overheating. Councilmember Aslan asked about the time it will take to recapture the cost of the investment. Mr. Roberts indicated that a co-gen system should be able to run 90% of the time which would equate to a five to six-year payback. | |||||||
