Title
Consider a resolution authorizing the Mayor to execute Supplemental Contract No. 1 with Freese and Nichols, Inc. for the Dry Branch Tributaries Project.
Body
The Dry Branch Tributaries project pertains to the Dry Branch Tributary of Brushy Creek along the east side of the South Creek neighborhood and one of its tributaries traversing through the Ray Berglund Subdivision. The project was identified by the City to address flood-carrying capacity and other sustainablity issues such as erosion which threatens utilities and real property, stream alignment, long-term stability, and accessibility for maintenance.
In August 2014, the City retained Freese and Nichols, Inc. to perform updated storm water analyses and modeling of the tributaries; to provide digital floodplain mapping; to explore and preliminarily develop feasible alternatives the City could construct for capacity or sustainability; and to estimate the construction costs associated with the various alternatives.
In order to implement alternative selected by the City, this supplemental contract will provide necessary professional assistance including: surveying; engineering analyses and design; preparation of construction drawings and required specifications; regulator compliance work; bid phase services; and construction administration services.
The original contract amount was $48,572.00; this Supplemental Contract No. 1 will increase the amount payable under the contract to $277,209.00.
Cost: $228,637.00
Source of Funds: 2014 Drainage Revenue Bonds
Recommended Action
Staff recommends approval.
