Labor Standards Committee Case Report. Replace deteriorated and non-functioning fan-coil units in the 16 perimeter offices of Building 7910. The exsiting units are part of a central system, portions of which require major refurbishment to restore service to the offices. The proposed project involves replacement of exisiting units with independently operated Packaged Terminal Air-Conditioners. To simplify this job, the existing two-pipe system used to heat/cool the fan coils has been determined to be radiologically contaiminated; even limited use as a ventilator (fresh air intake) has been curtailed. This winter the offices were forced to rely on 1500 watt electric space heaters. However inconvenient, it represented a solution to the heating problem. A portable make-shift cooling device unfortunately is not available for the approaching summer months. It is recommended the proposed solution be implemented by maintenance as soon as possible. Identical units were installed by maintenance in Building 5500/Anex which serves for this case as an estimating model. The estimate was further developed utilizing standard labor estimating techniques. The work will be performed by ORNL forces to iminiize interruption to building operations. The new units are readily available and their application here represents an expeditious solution to the problem. Since the building is fuly occupied, this work must be coordinated with all on-going building activities. The individual unit replacement approach lends itself to limited (one office at a time) disruption and a means of maintaining flexibility in the schedule. $60,000.
