STAFF REPORT
Change Order No. Eight directs the Contractor to rewire the
chiller control panels to provide for a constant source of
power for the operation of compressor sump heaters and various
cycling actions of the chillers.
A copy of the memorandum from Bill Doran, Construction Manager,
dated November 20, 1985, is attached. In this memorandum, Mr.
Doran describes the work, and recommends that Change Order No.
Eight be approved.
We concur with the recommendation by Mr. Doran that this Change
Order be approved.
The Budget vs. Bid Analysis dated 12-6-84, showed an amount of
$6,138.00 for change orders in process and $5,000.00 for
estimated future change order costs. The net additional cost
for Change Order Nos. 2, 3, 5, 6 & 7 is $7,302.78. Change
Order No.4 was for no cost. Therefore, approval of Change
Order No. Eight will not invalidate the financial report dated
12-6-84.
