EFTA01146225 LSJ • Library ac unit, we received two proposals to remove and replace the existing Trane unit that is failing and had operational issues since installation. The Trane unit could never keep the relative humidity levels in the library at set point and the air flow in the library is not balanced properly. Kent Magee of ARS hired a design engineer to review the ac unit issues and provide proposals for a total system replacement. Proposal #1 for a Carrier unit $158,989.00 Proposal#2, for a Aaron unit . $ 198.987.00 .After my review of the both proposals I requested more details on the unit specifications. Kent Magee sent us engineering data on the units expected design performance. The data quoted on the reheat section of the unit a 49% RH level. I requested the design engineer provide the control system design intent. What control system will control the unit? a design print of the system for the installation showing equipment location, an explanation of how the system will control set points in the library room. The engineer that did the design has gone missing Brice Gordon has contacted Kent Magee on several occasions and could not get any answers from his design engineer. Kent Magee is in the process of bringing a new design engineer on board to handle the design issues because he is only a installation contractor. Brice is expecting to hear back from him when he returns from a project in virgin gorda.
