. . . ~. ~ EN HILLS MEMORANDUM DATE: January 6,2003 TO: Aaron Parrish, Director Community Services ~~ . FROM: Dave Scherbel, Building Official SUBJECT: City Hall HV AC The new City Hall building's mechanical equipment needs to be regularly maintained. Due to the complex nature of the mechanical system, boilers, air handlers, V A V s, pumps, dampers, all computer program controlled by a Johnson Metasys system, needs to be regularly serviced by highly qualified service technicians to ensure the system is operating at peak efficiency. This will also provide a preventative maintenance program to limit more costly emergency repairs to the system. Staff obtained bids from four mechanical contractors to service the building. The quotes are as follows: . Harris Companies $3,284.00 . Johnson Controls $3,364.00 . Northern Air $3,120.00 . New Mechanic $4,140.00 After considering 'all aspects of the aboYe quotes, staff recommends that Johnson Controls be awarded the contract. Johnson Controls is the provider of the control and software equipment. Staff believes they are the most qualified to maintain our equipment. In addition to awarding the mechanical service contract, staff has over the past year, had numerous issues. with the mechanical equipment. The issues range from inconsistent temperatures (too hot/too cold), to high humidity levels. The humidity level has been at 70% and has affected the performance of printers & copy machines. Staff has had numerous conversations and meetings, both as a group and separately, with the mechanical engineer, mechanical contractors, and architect who all have different opinions on how to remedy the problems, often conflicting with each other. Staff has received a quote to install Carbon Dioxide detectors in the building to help control humidity and increase efficiency. The quote is for $4,650.00. There is no guarantee that this will remedy our problems.
