Resolution 6757 A rovin Chan a Orders No. 4-6 and Authorizin <br />PP g g g <br />Initiation of HVAC Changes for the City Hall Rehabilitation Project. <br />Director of Public Works Lee reviewed Change Orders 4-6. He explained Change Order 4 is a <br />credit of $1,193 back to the City for the elimination of sheet rocking from the project. He <br />explained Change Order 5 is for additional costs of $1,997 for changes in the millwork <br />throughout the project. He explained Change Order 6 is for additional costs of $8,522 to remove <br />a hardened concrete steel area within the Police area. <br />Director of Public Works Lee reviewed changes in the HVAC system and explained it includes <br />the replacement of three roof top units with one unit that needed a new control system. He <br />reviewed five options for the wiring and control problem. He stated Staff is recommending the <br />option to change the control system to DDC and replace RTU Number 6 for a cost of $27,353, <br />and is looking for direction from the Council to move forward with this option. <br />Director of Public Works Lee stated that five of the twelve heating coils within the air system <br />need to be replaced. He stated Staff is recommending replacing all twelve at the same time at a <br />cost of $11,255. <br />Director of Public Works Lee stated the last item is for additional furniture required for one of <br />the City offices that needs free-standing furniture. He stated this is due to a change in <br />assignments for one of the City's employees. He stated the cost of this additional furniture is <br />$2,105. <br />Director of Public Works Lee stated it is recommended the Council approve Resolution 6757 <br />Approving Change Orders 4-6 and Authorizing Initiation of HVAC Changes for the City Hall <br />Rehabilitation Project. <br />Councilmember Flaherty asked about the DDC controls in the HVAC improvements. He asked <br />how the option was put into the initial system. He stated he did not recall getting the option <br />between DDC and an analog control system which is considerably less expensive. He stated it <br />makes sense if the City has the equipment and wants to bring up the other equipment that is <br />compatible. <br />Councilmember Flaherty stated he understands the tonnage is significantly over from what is <br />required because there is no one down there and it is only used for storage. He commented the <br />dew point has the tendency to get high in the area. He stated he did ask the question if there are <br />other alternatives to replacing the new unit as opposed to changing out just the coils or putting <br />other things on there that could do the job. <br />Mayor Marty asked if the City is still on budget for the project with the contingency funds. <br />Director of Public Works Lee stated it is and he would provide a summary of all changes to give <br />a clear picture as to where the project is at. He stated it is clearly far below the budget of $1.6 <br />
