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: April 27, 2010
RE: Consider approval of Change Order Number 3 to the South Coppell
Road (ST 07 -02) project in the amount of $61,997.33 for Drainage
Channel work and intersection improvements at Coppell Road and
Southwestern Blvd., as provided for in CIP funds; and authorizing
the City Manager to sign all necessary documents.
On June 9, 2009 council awarded a contract to JRJ Paving, LP in the amount of
$1,326,827.79 for the reconstruction of South Coppell Road from Bethel Road to
Southwestern Blvd. The award also included an $80,000.00 potential bonus set aside for
early completion. Since this award, two change orders have been approved that increased
the contract amount by $68,446.50.
During the progress of construction, it was discovered that quantities established for the
contract did not include a considerable amount of work necessary for the construction of
an off -site drainage channel. That work was shown in the plans; however the quantities
in the bid tabulation did not include these amounts. The two items in question are
excavation and establishing grass.
The original contract price for excavation was $7.88 per cubic yard, and we are adding
7,129 cubic yards with this change. The original contract price for grass was $4.73 per
square yard, and we are adding 10,722 square yards with this change. We have negotiated
with the contractor to try to minimize the cost of this change. We allowed him to dispose
of the excavated material on city owned property, and he has reduced his price to $3.50
per cubic yard, or approximately half the original cost. We have also agreed to use
hydromulch and curlex with seed rather than the block sod originally bid. Block sod will
still be used in front of all homes and businesses along the road, just not in the vicinity of
the channel and other city owned property. As a result of this, the added grass will also
cost less than half the original contract amount on a per square yard basis.
This change order also includes additional improvements in the intersection of Coppell
Road and Southwestern Blvd. As paving has been completed on both sides of the
intersection it has become apparent that the intersection itself is in a state of disrepair and
requires removal and replacement of the paving. Unit pricing for the work necessary is
included in the original contract, this change simply increases the quanity to include the
area of the intersection.
In addition to the extra work this change order includes additional time for completion of
the project. As you know the weather has been unusually wet during the course of this
project. The contractor has requested 82 additional days. We have verified 50 days they
could not work due to weather. We have estimated that the additional excavation and
grass work in the channel took 28 days. This is a total of 78 additional days, and brings
their contract completion date to April 30, 2010. The wording of the contract ties their
incentive for early completion to the original contract time, which means they no longer
have an opportunity to earn any of the incentive. This additional time simply pushes
back their disincentive clause.
Approval of this change order will allow the city to compensate the contractor for the
channel work that was indicated in the original plans; however the quantities were
inadvertently left out of the bid documents. This will also authorize the additional work
to reconstruct the intersection of Coppell Road and Southwestern Blvd. It's 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 $61,997.33 with an additional
78 calendar days.
Staff will be available to answer any questions at the council meeting.
