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.
