Engineering is the process of <br /> approving a change order for this project which will result in a 29.14% increase from the original contract <br /> amount and wishes to obtain your approval as well. This is the only change order for this contract as the <br /> work is complete and we intend to make final payment in the next pay estimate. <br /> Background <br /> Due to age and deterioration the headgate structure of the Mill Race located at approximately 10"' and <br /> Ferry Street, Engineering worked with Parks and Open Space to design the rehabilitation of the structure <br /> and its fixtures. The City publicly advertised this project and received three bids as follows: <br /> Triad Mechanical, Inc. $67,868 <br /> Brown Contracting $84,654 <br /> Triton Group $118,300 <br /> In working with Parks and Open Space staff, it was determined that the headgate and underground pipe <br /> system lacked access for maintenance and cleaning, and it was decided to add a manhole to the 30" <br /> diameter concrete pipe just beyond the headgate. I requested Triad to submit a proposal for the extra work <br /> which they did on 10/20/06 for a lump sum cost of $24,433. I felt this was excessive and asked if Triad <br /> would be amenable to performing the work on a time and materials basis which is allowed under sections <br /> 00196 and 00197 of our Standard Specifications for Construction if a price agreement cannot be made <br /> prior to the work. As stated above, the installation of this manhole was a benefit to the City for <br /> maintenance and access considerations. Additionally, this work benefited the contractor and the City in <br /> assisting in performing dewatering activities for the primary contract work. <br /> In addition to the manhole work, there were several unanticipated items of work that arose that were <br /> addressed by the change order and resulted in a net increase to the contract. <br /> Additional Work <br /> As stated above, Triad originally proposed to install the manhole for $24,433.
