He stated east of Highway 42 there are very strong currents and local flows in the open space areas. He noted there are condos, homes and a school on the Lafayette side, which have seen some damaging flooding. In the downtown area, the water tends to pond, but they may have very strong undercurrent around the inlet areas. Mayor Pro Tem Dalton agreed with Mayor Muckle that cities provide infrastructure to protect their residents' properties by eliminating flooding problems. Public Works Director Kowar explained staff will proceed with the design and the loan applications. Within a month or two staff will present a loan agreement and a contract with Urban Drainage for Council consideration. CONSTRUCTION MANAGEMENT SERVICES AGREEMENT WITH DEWBERRY ENGINEERS, INC. FOR WASTEWATER TREATMENT FACILITY UPGRADES Mayor Muckle requested a staff presentation. Public Works Director Kowar introduced the City's Water Resources Engineer Dmitry Tepo, who will be the Project Engineer for this project and Patrick Radebaugh representing Dewberry Engineers, Inc., who will provide the design and assist in the grant applications. Water Resources Engineer Tepo explained before the City Council is a Construction Management Services Agreement with Dewberry Engineers, Inc., for Waste Water Treatment Facility upgrades. For the past year and a half, Dewberry and the City have been working on designing the upgrades to the Louisville Wastewater Treatment Plant. These upgrades are regulation driven by the Colorado Department of Public Health and Environment. Dewberry's scope of work for the current contract is for the design services only. Staff proposes another contract for bid phase services, construction management, as well as design of minor items relating to WWTP upgrades, not included in the original scope. Staff recommended the City Council contract with Dewberry for bid and construction phase services on sole source basis in the amount of $1,557,080. Staff recommended sole source, rather than an open bid, based on the following: • The design drawings and specifications were produced by Dewberry and Dewberry is in the best position to address contractor's questions and provide clarifications that will come up during bidding and construction. • If a new firm is hired, the City could encounter liability issues during the construction and warranty periods of the WWTP upgrades. If warranty work is required, it will be difficult to identify the responsible party between the design consultant, construction management consultant, contractor, or the City.
