Griff'm, P.E., Director of En~neering/Public Works }~/ May 9, 2000 Consider approval of Change Order #5 to the Sandy Lake Road Project #ST 93-02 for the extension of Sandy Lake road through the MacArthur Blvd. intersection in the amount of $1,211,687.07 to Ed Bell Construction Company; and authorizing the Mayor to sign. Summary: Staff has always anticipated a large change order to this project; · This intersection was not initially included with the City's section of Sandy Lake Road because it was included with Dallas County's section which was approximately 9 to 12 months ahead of our design contract; and · It's better to work with one contractor on the entire project for resolution of any current or future issues. In 1993 the City began the process of selecting an engineering firm to design Sandy Lake Road from Denton Tap to MacArthur Blvd. In mid-1992, Dallas County had selected a firm to design Sandy Lake Road from MacArthur Blvd. to the east city limits. Because the County project was initiated prior to our project, their project included the design and construction of the MacArthur/Sandy Lake intersection to approximately 300 feet west of MacArthur Blvd. That point is directly in front of the Kroger Food Store at the northwest comer of MacArthur and Sandy Lake Road. It became apparent several years ago that our project would track ahead of the County project. This created a dilemma on the timetable to construct the MacArthur/Sandy Lake intersection. I made inquiries to Dallas County about the feasibility of breaking out the design of the MacArthur/Sandy Lake intersection and constructing it as a separate project to the overall County project. After numerous discussions, Dallas County agreed to breakout the design of the MacArthur/Sandy Lake intersection from 300 feet west of MacArthur Blvd. to approximately Kimbel Court. This allows the construction of the entire intersection with mm lanes in both directions. It also allows for the construction of improved traffic signals at the intersection so that we can better facilitate traffic movements in all directions through the intersection. The design was not complete and available at the time we bid the City's section of Sandy Lake Road. However, during the bidding process all perspective bidders were informed that there was a strong possibility that a major change order would "CITY OF COPPELL ENGINEERING - EXCELLENCE BY DESIGN" be forth coming at some time during the construction of the project that would involve the construction of the MacArthur/Sandy Lake intersection up to approximately Kimbel Court. In September 1999, the City received 95% complete plans from Dallas County on the improvements through the MacArthur/Sandy Lake intersection. Several options were available to the City. One was to totally complete the plans, generate a set of specifications and then put the project out to bid. This had several drawbacks: 1) The actual timing of the completion of the plans and specifications; and 2) Our current contractor is constructing water lines through the MacArthur intersection and with two contractors working specifically within the intersection there could be problems in the future with neither contractor taking responsibility if something failed within the intersection. A second option was to issue a change order to the Sandy Lake Road project. Therefore, we contacted the current contractor on the project, Ed Bell Construction, provided him a set of the 95% complete plans and asked for a quote on a change order to the project. Our thoughts on this process was that with one contractor working within the intersection there would be only one point of contact for any conflict or future problems. This makes for a much smoother operation. I had anticipated a large change order several years ago however, since that time construction prices have risen, plus the work involved with the entire change order is in a high volume intersection. This will create traffic control and constructability issues. There are over 20,000 vehicles a day on MacArthur and approximately 15,000 vehicles a day on Sandy Lake at this intersection. To maintain movement of traffic through the intersection, the contractor will need a minimum of four separate and distinct move-ins within the intersection and potentially six. This will allow the contractor to maintain at least one lane of traffic in all directions while working within the intersection. Needless to say, work within the MacArthur/Sandy Lake intersection will worsen an already overloaded intersection. If Council approves this change order, I have asked the contractor to direct as much activity within the MacArthur intersection as possible during the summer months. However, before the contractor can even make that commitment, there are other issues associated with the construction of Coppell's 30" water line and the lowering of the Dallas water line that need to be resolved. Staff recommends the award of Change Order #5 to Ed Bell Construction Company in the amount of $1,211,687.07 for the continuation of Sandy Lake from approximately 300 feet west of MacArthur to approximately Kimbel Court. Staffwill be available to answer any questions at the Council meeting.
