AGENDA ITEM: Inwood Booster Station Improvements - Change Order No. 5 and
Compensating Change Order No. 6
SUBMITTED BY: Jack Griffin, City Engineer REVIEWED BY: Kristina Handt, City Administrator Rob Weldon, Public Works Director
Chad Isakson, Project Engineer
ISSUE BEFORE COUNCIL: Should the City Council approve Change Order No. 5 and Compensating Change Order No. 6 for the Inwood Booster Station Improvements? BACKGROUND: Magney Construction, Inc. was awarded a construction contract to complete the Inwood Booster Station Improvements on April 5, 2016. The booster station construction work is now complete.
PROPOSAL DETAILS/ANALYSIS: Magney Construction, Inc. has submitted Change Order No. 5 to decrease the contract by $1,285.50 as a credit for not providing the chlorine breathing apparatus included
in the contract. City Staff reviewed the equipment needs and response procedure and determined this equipment was not necessary.
Compensating Change Order No. 6 is also included to revise the estimated quantities for each work item listed in the bid schedule to the actual quantities installed on the project at the unit bid prices. This change order reflects a net decrease to the contract amount by $14,135.20. This decrease is due to payment on actual quantities installed and a lower cost to install utility services to the building than originally planned. FISCAL IMPACT: Change Order No. 5 will decrease the contract in the amount of $1,285.50 bringing the revised construction contract to $1,314,148.95. Compensating Change Order No. 6 will decrease the contract in the amount of $14,135.20 bringing the revised construction contract to $1,300,013.75. With approval of these change orders the project remains within the authorized project budget and contingencies. RECOMMENDATION: Staff is recommending that the City Council approve, as part of the Consent Agenda, Change Order No. 5 and Compensating Change Order No. 6 for the Inwood Booster Station Improvements. If removed from the consent agenda, the recommended motion for the action is as follows:
“Move to approve Change Order No. 5, thereby decreasing the contract amount by $1,285.50, and
Compensating Change Order No. 6, thereby decreasing the contract amount by $14,135.20 for the Inwood Booster Station Improvements” ATTACHMENTS:
