SUBJ: Approve Change Order No. 1 to Lake Ann Park Utilities q—,.'7 2 '
Project No. 91 -15
I The attached Change Order No.1 for the Lake Ann Park Utilities Project No. 91 -15 contains a few adjustments
g Project 7
to the contract scope for the project. The significant adjustment involves the addition of the remote transmission
I unit (RTU) to the lift station which will be tied into the City's telemetry system at a cost of $12,580.04. This
work would be completed by the City's telemetry contractor, Bentec Engineering Corporation. This cost
proposal appears to be comparable to the City's system -wide proposal for the telemetry system.
I Change Order No. 1 also includes the deletion of the emergency power generator connection plug which will,
in effect, yield a deduct of $364 from the contract. The other notable changes relate to the water system where
I a Woodford Model MK6B yard hydrant will be abed at no additional charge; however, it is proposed to add one
more yard hydrant to the project at an additional cost of $912.
The original contract amount was $108,057.64. With the addition on Change Order No. 1, the revised contract
1 amount would be $121,185.68. Again, the primary cost element to this change order involves the additional
remote transmission unit (RTU) which staff believes is a necessity to integrate with the system's overall
telemetric system and serve the needs of the park. It is therefore recommended that contract Change Order No.
I 1 in the amount of $13,128.04 be approved for the Lake Ann Park Utilities Project No. 91 -15 to establish a
revised contract amount of $121,185.68.
