SUBJECT
Title
Consider recommending approval of a contract with Larrett, Inc., Kaufman, Texas, for construction of the initial phase of the Hickory Substation underground transmission and distribution line duct banks in an amount not to exceed $892,455.00. (RFP #6416)
Body
BACKGROUND
RFP #6416 was advertised to seek proposals for construction of certain sections of electrical duct banks that will be needed to support the new Hickory Substation. Exhibit 1 is a drawing that shows the locations for the planned duct banks. A duct bank is a grouping of conduits (pipes) for underground electrical conductors that provide a path for, and physical protection for, insulated electrical conductors.
The City of Denton is currently updating utilities within Hickory Street from Bonnie Brae in to Carroll Boulevard in preparation for repaving that section of Hickory Street. The Street Department has worked to coordinate utility replacements, upgrades, and new installations ahead of repaving. Repaving is scheduled later this year. DME developed RFP #6416 to support this city effort.
As can be seen from the drawing in Exhibit 1, much of the conduit will be located under the pavements of Hickory Street and Avenue H. The duct bank sections to be constructed under RFP #6416 will extend from inside the new substation boundary to appropriate points outside the station. One duct bank will be for distribution conductors, and one will be for 138kV transmission conductors. Future phases of construction, will extend the duct banks to their ultimate connection points. Additional transmission and distribution duct bank construction will be required in other areas around the substation as the substation project progresses.
The Hickory Substation is an approved CIP project, and the City Council has directed that the substation be constructed as a Gas Insulated Substati...
