　　Subject: Air-conditioning Installation Costs for East Hall
　　Date: June 4, 2006
　　I am writing to inform you of the costs of installing air-conditioning for the seven offices and two studio classrooms in East Hall.
　　Office and Classroom Installation
　　Estimates were obtained from three contractors on the costs of covering the offices and class-rooms. All these three were in the $20,000 to $25,000 range.The work would take .about three weeks.
　　Because the central unit would be installed on the roof, some noise problems might occur during a four-or five-day period. And this work could be started from this weekend, and the over-time labor costs of about $1,500 have been included in the estimates.
　　Additional Installation
　　Because a larger installation, including a more powerful central unit, would be necessary to handle the halls and stairways, an additional $6,000 would be required for the equipment. If this additional work were delayed until a later time, a new central unit would be required along with changes in the pipe way.
