JANONIS <br />FROM: STREET & BUILDING SUPERINTENDENT <br />DATE: NOVEMBER 19, 2014 <br />SUBJECT: PUBLIC WORKS HVAC REPLACEMENT ($412,500) <br />BACKGROUND <br />The Public Works facility currently has one (1) 30 -ton roof top air conditioning unit serving the <br />administrative area. This unit is an original piece of equipment installed in 1988 when the Public Works <br />facility was constructed. The expected useful life for the unit is 20 years. Currently the supply fan motor <br />and pressure controls are failing and the air conditioning unit has had a number of costly break downs in <br />the last few years including three (3) compressor replacements. <br />In addition, nine (9) heat -only roof top units are installed servicing the main garage, vehicle maintenance <br />area and divisional shops. These units are also original installation from 1988 and have exceeded the <br />expected useful life of 20- 25 years. Four (4) of these units are experiencing significant degradation in <br />performance. <br />On July 2, 2014 the Village Board awarded a contract to CS2 Design to prepare bid documents, oversee <br />the bidding process and provide construction management services. CS2 Design recommends replacing <br />the 30 -ton roof top unit servicing the administrative offices and the four (4) failing heat -only units <br />servicing the main garage. The remaining five (5) heat -only units will be slated for replacement within <br />the next 5-7 years. <br />Appropriate bid documents were developed. Six invitational bids were mailed and a notice was published <br />in the local newspaper. A mandatory pre-bid meeting to explain the scope of the contract was held on <br />October 21, 2014.
