Griffin, P.E., Director of Engineering/Public Works FROM: Keith R. Marvin, P.E., Project Engineer DATE: December 13, 2011 RE: Consider approval of Change Order Number 2 to the Old Town Coppell and Bethel Road Infrastructure Improvements (ST10 -02) project to JRJ Paving, L.P. in the amount of $74,677.00; as provided in CIP funds; and authorizing the City Manager to sign all necessary documents. On September 13, 2011, Council awarded a contract to JRJ Paving, LP in the amount of $4,654,190.39 for the construction of Old Town Coppell and Bethel Road infrastructure improvements. This award amount included a $295,000.00 potential bonus set aside for early completion of various milestones throughout the project. Since this award, one change order was approved that had no monetary value associated with it, it simply adjusted milestone dates established in the contract at the request of the city's development partner and the contractor. The change order before you this evening is due to unforeseen utility conflicts encountered in the Bethel Road portion of the project. As discussed during the award of the project this area of town contains some of our oldest utility infrastructure. The records available for us to use during the design have proven to be incomplete and less accurate than we would have liked. This change funds the relocation of an existing 16" water line that is in direct conflict with the proposed 42" storm drain being constructed with this project. We are also adding a pay item for the contractor to continue to investigate and remove old water lines. We are adding this as an hourly rate pay item to be used at the city's discretion. As of the date of this meeting, the contractor has expended approximate 30 hours investigating and tracing existing water lines. We are proposing to pay them for the work completed to date, and include an additional 70 hours to be used in the future to trace the balance of the old lines in the area and ensure they are properly taken out of service. 1 Approval of this Change Order Number 2 will allow the contractor to move forward with the relocation of this conflicting water line, and continue with the Bethel Road portion of this project. It is our opinion that the contractor has provided fair and reasonable pricing for these changes, and we recommend approval of this change order in the amount of $74,667.00. Staff will be available to answer any questions at the council meeting. 2 CITY OF COPPELL CHANGE OR EXTRA WORK ORDER PROJECT: Old Town Coppell and Bethel Road Infrastructure Improvements (ST 10 -02) CONTRACTOR: JRJ Paving, L.P.
