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. ……11 …… If this additional work were delayed until a later time, a new central unit would be required along with changes in the pipe way ……12…… Summary

　　The total job for the building would be about $ 35, 000 if done at one time. A two-stage installation would cost about $55 ,000. I can get official bids at your request.

　　Example: A

　　A As you suggested, we also sought information on the additional cost of air

　　conditioning in the entrance halls and stairways.

　　B All these three were in the $ 20,000 to $25,000 range.

　　C This later installation would cost about $20,000.

　　D However, class interruption should be minimal.

　　E In the same way, each of these three would take at least one month.

　　F Therefore ,the total cost was this $6 ,000 plus another $5,000.

　　G Labour costs would be an additional S 5 ,000,bringing the total cost of the addition to $11 ,000.

　　H Each faculty member could expect to have workers in the office for about one day.

　　I So faculty members can continue their office work as usual.
