Whiting Letter Page 2 This cost increase may be offset by cost savings in reducing all the rooftop units to standard units with the exception of the Multi-Purpose Room with would remain with stainless steel components. This is a Value Engineering item that is currently being reviewed. Another option that could be considered at this time would be to upgrade the entire HVAC system. This would involve adding a hot water boiler and variable air boxes (same as above)with reheat coils to the current system. This would permit the system to run more efficiently and provide greater control to the areas. It is estimated that the cost for this system could be approximately$100,000. However,the energy saving payback could be recovered in a period of 5-10 years. With this system,the unit heaters located in the vestibules could be replaced with hot water coil heaters, eliminating the electric heater specified. If this option is selected, a supplemental service agreement to redesign the systems will need to be issued. The terms of the agreement will be based on hourly rates not to exceed approximately$8,000. Dunham and Associates will provide additional information to you on the systems,costs and paybacks. A decision on this matter needs to be made as soon as possible,since the ductwork is already being installed and the equipment must be ordered to avoid any delays to the project. Please note also,Value Engineering on the project to date has saved approximately$90,000,not including some of the proposals for the mechanical systems. Should you require any additional information or assistance,please contact me. Respectfully submitted, WAI/Continuum Dean A.
