STAFF REPORT
Change Order No. Five directs the Contractor to install a 2" conduit
for the irrigation sprinkler control wire at an increase in contract price of
$367.81. This conduit was necessary to allow conductors from the irrigation
valves to be connected to the controller located inside the building. Since
the landscaping and irrigation plans were not completed when the electrical
package was bid, this conduit was not shown.
A copy of the memorandum from Don Rogers, Construction Manager, dated
February 24, 1985, is attached. In this memorandum, Mr. Rogers describes
each item of work, and recommends that Change Order No. Five be approved.
We concur with the recommendation by Mr. Rogers that this Change
Order be approved.
The Budget vs. Bid Analysis dated 12-6-84 showed an amount of $6,138
for change orders in process and $5,000 for estimated future change order
costs. The net additional cost for Change Orders No.2 and 3 is $5,269.29,
since Change Order No.4 was for no cost. Therefore, approval of Change
Order No. Five will not invalidate the financial report dated 12-6-84.

Attached is change order #5 with signatures for your approval. As we discussed,
we have cancelled all items except the conduit for irrigation controller.
RFQ #l is to add 2" conduit for irrigation sprinkler control wires. The
controller is located in the mechanical equipment room. We instructed Cox
Electrical to install a conduit in and below the concrete slab and footings
to be used as a raceway for the controller wires. This had to be done back
in August of 1984. Without this, the controller would have had to be
located outside the building which would have been subject to vandalism.
'We recommend that this change be approved. If you need any further
information and/or backup, please contact us.
