Item No. 7H <br />Meeting Date: July 23, 2007 <br />Type of Business: CB <br />WK: Work Session; PH: Public Hearing; <br />CA: Consent Agenda; CB: Council Business <br />Administrator Review:___ <br /> <br />City of Mounds View Staff Report <br />To: Honorable Mayor and City Council <br />From: Greg Lee, Director of Public Works <br /> <br />Item Title/Subject: Resolution 7122 Approving Change Order No. 38 for <br />the City Hall Rehabilitation Project <br /> <br /> <br />Background: <br />Adjustments recommended during construction are referred to as Architectural <br />Supplemental Information (ASI’s). These are common in all architectural projects <br />and are even more prevalent in re-model projects. Many of these items are <br />simple adjustments that do not require additional work from the contractor. These <br />are noted as “NC” – no charge. Other adjustments may include additional <br />materials or labor and are listed as an additional cost, while other ASI’s may <br />include a credit in cases where materials or labor that were included in the <br />original contract are no longer necessary. <br /> <br /> <br />Discussion <br />When performing a final summary report of items associated with the City Hall <br />Rehabilitation Project, it was determined that there were plumbing pipes that <br />were not insulated. It is a trade practice in this area to insulate only to the valves. <br />The International Energy Code does not specifically state that this is an allowable <br />practice, and it was not written into the specifications for this project. However, if <br />the 3-4 feet of un-insulated pipe is left un-insulated, the actual energy lost would <br />be negligible. Most of the pipes are located in a return air plenum, where the heat <br />would only transfer to the return air stream, and thus, not be lost. The heat would <br />only be present when the thermostat calls for heat, because the hot water is <br />stopped at the valve when there is no heat called for. Based on this, the City’s <br />consulting mechanical engineer recommends not requiring insulation of these <br />areas. There is approximately 80 feet of such un-insulated pipe, which <br />represents a project credit to the City in the amount of $200. <br /> <br /> <br /> <br /> <br /> <br />
