MEMORANDUM
TO: Mayor and City Council
VIA: Kenneth M. 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.
