CITY COUNCIL <br />AGENDA ITEM 5A <br />STAFF ORIGINATOR: Rick DeGardner, Public Services Director <br />MEETING DATE: May 26, 2020 <br />TOPIC: Consider Resolution 20-50, Approving Air Duct and Diffuser <br />Cleaning at Civic Complex Contract <br />VOTE REQUIRED: 3/5 <br />INTRODUCTION <br />The City Council is being requested to authorize the cleaning of the air duct work at the Police <br />Department and all diffusers at the Civic Complex (Police Department, City Hall, New <br />Creations). <br />BACKGROUND <br />As a result of concerns brought forth from some employees within the Public Safety <br />Department, Industrial Hygiene Services Corporation (IHES) was retained to conduct indoor <br />air quality and fungal sampling at the Police Department. The sampling occurred on April 28, <br />2020. The results of the fungal spore samples showed that there is not an indoor fungal air <br />quality problem. All the indoor air quality parameters were also within all regulations and <br />recommendations. The only abnormal results were the fungal tease tape sample collected from <br />the supply diffuser (report attached). <br />IHES recommends that all supply diffusers within the Civic Complex be cleaned. In addition, <br />we are recommending all supply and return air ducts in the Police Department be cleaned. With <br />the Civic Complex being in operation since 1999, it makes sense to clean the duct work at the <br />same time the diffusers are being cleaned. Based on the results of the duct cleaning in the <br />Police Department, we will be able to ascertain the level of urgency of cleaning the remaining <br />duct work in the Civic Complex. <br />NAC Mechanical installed the original HVAC system and has been the City's HVAC <br />contractor ever since. NAC Mechanical has obtained two quotes to clean all diffusers in the <br />Civic Complex, and clean the supply and return air ducts at the Police Department. <br />Staff recommends accepting the NAC proposal that includes subcontracting with KMS Air <br />Duct Cleaning in the amount of $11,065.00 (see attached). Funding will be from the General <br />Fund Operating Contingency. <br />RECOMMENDATION <br />Approve Resolution 20-50. <br />ATTACHMENTS <br />Resolution 20-50 <br />IHES Report, dated May 6, 2020 <br />NAC Proposal, dated May 19, 2020 <br />• <br />• <br />
