Title
Consider a resolution determining that Chasco Constructors provides the best value for the City for the Ryan's Crossing Drainage Outfall Improvements Project and authorizing the Mayor to execute a Standard Form of Agreement.
Body
Council previously approved the use of the Competitive Sealed Proposal method for determining the most qualified contractor for the above referenced project. Staff selected this method due to the project complexity and special considerations associated with construction near an existing dam.
The City received six proposals on February 7, 2018. The evaluation committee consisted of representatives from the City, the design engineer from Freese and Nichols, and the dam’s owner which is the Upper Brushy Creek WCID. The committee members independently reviewed and ranked each proposal considering the selection criteria outlined in the bid documents. The selection criteria included the contractor’s team qualifications, the project plan, approach and quality control, and past project experience and references.
The evaluation committee unanimously selected Chasco Constructors proposal as the best value to the City according to the selection criteria. Staff recommends awarding the Ryan’s Crossing Drainage Outfall Improvements contract to Chasco Constructors in the amount of $191,895. A copy of the final ranking sheet and bid tabulation is attached with this document for your reference.
The project consists of demolition of an existing concrete flume and headwall, extending the existing 54-inch reinforced concrete pipe to the toe of the dam embankment and installation of a concrete impact basin to minimize erosion. Rock riprap will also be installed at the downstream portion of the impact basin to further protect the area from erosion.
Cost: $191,895.00
