We will proceed. Thanks. We have revised the drawings to reflect traffic buttons.
One of my goals is to get the quantities as reasonably accurate as possible given the age of the plans and
underlying survey, and the incorporation of revisions that were not part of the County's project. My experience,
like that of the City's, has been that when revisions are made it complicates the quantity take off process
because it increases the risk of items "falling through the cracks". For instance, the new median opening in
addition to increasing associated paving quantities, will increase several other quantities including traffic buttons
and markings, temporary traffic control, and PVC sleeves. For this reason we are going back through all of the
changes to focus on their effect on the quantities.
Of particular concern to me is the amount of Earthwork that will have to be completed. For this project we
surveyed cross sections at each end of the project and at locations that were identified in the scope where we
collectively knew changes due to development and construction had occurred. However, we were not
contracted to go back and survey all areas. The original survey was done so long ago, it is my expectation that
ground movement has occurred that will affect the actual quantity that the Contractor will be asked to perform.
Collectively we need to take appropriate measures within the bidding and contract documents to protect Coppell
from rampant and excessive claims for extras during construction.
It is because of this very concern that I previously offered to perform a coordination review of the final
bidding package for no extra fee. I am still willing to provide this should you desire.

Bill:
Ken wants the median opening so proceed with the change.
We met yesterday to discuss the plans and specifications for the project. We have concerns about the
quantities being correct (i.e. stamped concrete and the paving buttons). We previously provided a copy
of our updated button specifications but the plans still reflect jiggle bars. The city does not use jiggle
bars but uses a double row of 4-inch white round single reflective buttons. Many of the pay items are
'plans quantities' so it is imperative that the quantities be correct. Under the engineering scope you were
supposed to revise bid quantities and provide two copies of the supporUng documentation.
Thanks

our fee be increased by $446.
Breakdown of hours:
