MEMORANDUM
TO: Don Ashworth, City Manager
FROM: Charles Folch, Director of Public Works
DATE: June 18, 1997
SUBJ: Approve Change Order No. 2 to Well 7 - Project No. 94 -3
The attached change order involves some additional work, outside of the original scope of the
contract, associated with the manual supervisory control valve and automatic flow valve switch
for the fire sprinkling system and connect them to the City's telemetry system so that if sprinkling
system should activate the telemetry system will page the appropriate utility personnel. The other
work task addition involves providing for an external building alarm system which would also
activate should the fire protection system in the building be activated. These revisions were
requested by the Fire Marshal from review of the submitted shop drawings.
The total amount of Change Order No. 2 is $2,664.15. The original contract amount was
$384,829. With the approval of Change Order No. 2 the revised contract will be $387,493.15. It
should also be noted that Change Order No. 1 did not involve a cost increase or decrease to the
contract, but only an extension of time to the project completion schedule due to coordination
with the water system improvements.
It is therefore recommended that Change Order No. 2 in the amount of $2,664.15 to Well No. 7
contract, Project No. 94 -3, be approved.
