TO: Mayor & City Council
Gene Anderson, Interim City Manager
FROM: Carla Easton, City Engineer
SUBJECT: JOHNSON WOODS SEWER & DRAINAGE IMPROVEMENTS CONTRACT
CLOSE OUT WITH RBIS, LLC
DATE: February 4, 2020
BACKGROUND: The Johnson Woods Sewer & Drainage Improvement project was planned and
scheduled as part of the 2013 Bond Fund for Water and Sewer Improvements. It included
replacement of sanitary sewers and channel restoration along the drainage channel running from
Lamar Avenue to Clark Lane, located between Johnson Woods Drive and 31St St SE. AECOM
and Hayter Engineering Inc. prepared the construction drawings and specifications.
The Johnson Woods construction project was awarded to RBIS, LLC on April 8, 2019, for a
contract amount of $1,499,501.00 and contract time of 270 calendar days. Change Order 41 was
administratively approved by John Godwin on June 13, 2019, increasing the contract amount by
$40,529.60 in order to cover the cost to install the sewer main by bore rather than open trench,
saving significant time and inconvenience to the neighborhood. During the course of the project,
several contract items were overrun due to field conditions, including extension of a gabion wall,
fence replacement, an additional sewer manhole, and rock riprap needed to line the creek bed near
Lamar Avenue. Approval of a final reconciliation change order in the amount of $57,955.54 is
needed with project close out. The project was completed within 230 calendar days.
STATUS OF ISSUE: RBIS, LLC has completed all work under this contract. A final walkthrough
of the project was performed on January 13, 2020, and all punch list items have been addressed.
The engineer of record has reviewed all close out documents and recommends approval of final
payment.
The total pay amount to RBIS, LLC for all work under this contract is $1,597,986.14. Progress
payments have been made in accordance with the contract documents, and the only remaining
payment is for the retained amount of $79,899.31, which will be released upon approval of Change
Order #2 and final acceptance by City Council. Staff will retain $5,000 until full vegetation along
the creek is established and verified this spring.
BUDGET: Funds are available in the 2016 Utility Bond Fund.
RECOMMENDATION: Approve Change Order #2, final payment and contract close out for the
Johnson Woods Sewer & Drainage Improvement project with RBIS, LLC.
