. . . ~ ~HILLS MEMORANDUM DATE: Agenda Item 6.A.l March 26, 2003 TO: Mayor and City Council Aaron Parrish, Interim City Administrator/Director of Community Services Da-;e Scherbel, Building Official ~ ~ . FROM: SUBJECT: City Hall Mechanical System This memo is to serve both as an update and a request for additional funds to help resolve the mechanical issues at City Hall. As you already know, Johnson Controls completed a commissioning report on the Heating, Ventilation, and Air Conditioning (HV AC) and Building Automation Systems (BAS). A copy of that report is enclosed. Although much of the report is very technical in nature, it does plainly list pass or fail notations for many of the functional tests that were performed. In reviewing the report it is apparent many deficiencies exist. Staff has had two meetings with the architect, mechanical engineer, general contractor, and the subcontractors directly involved in installing the HV AC system for City Hall.

The recheck of the building's system is very technical in nature and staff believes this recheck is necessary to determine if the building is functioning as originally intended. Staff is of the opinion that most of the building deficiencies will be corrected. One question does reJ;llain regarding the dehumidification of City Hall. Since the building was designed with no dehumidification process, staff wonders if current corrective actions will correct or lower the high humidity that the building experienced during the summer months. Once we determine that all the proper corrections have been made we can establish a base line for any further modifications that may need to occur. To summarize, all current corrections acknowledged in the commissioning report, will be made by the contractor at no additional cost to the city. The general contractor (Rochon) has agreed to pay the entire cost of the commissioning report ($7,468). The requested additional $4,330 for a
