Consider executing Supplemental Contract No. 1 with Halff Associates, Inc. for the
Purple Sage Drive Culvert Project.
On February 6, 2015 the City Manager approved a Contract for Engineering Services
with Halff Associates, Inc. to design and prepare construction plans for the Purple Sage
Drive Culvert project. In order to reduce the frequency of roadway and property flooding
that has been experienced in the past, the aforementioned plans are for the
replacement of the culvert under Purple Sage Drive just west of Rawhide Drive in the
Chisholm Valley neighborhood.
Now that the plans have been completed and have been issued for bids, it has become
apparent that the City will require some assistance from the engineer during the bidding
and construction phases of the project.
Supplemental Contract No. 1 will allow the City to request services from the engineer
as necessary during the bid and construction phases of the project and will increase
the original contract amount by $8,761.30; bringing the total under the contract to
$57,108.30.
Staff recommends approval.
