Dave,
We have discussed the Southwestern Blvd project with the City Manager's
office, and we would like to proceed with the redesign of the bridge,
and the narrowing of the roadway to 41' B-B. Due to the cost involved
in a contract amendment with Halff Associates we will need to go to City
Council forapproval.
Our next council meeting is January 13th. I will need a contract
amendment from you by January 6th in orderto get the packet submitted
in time forthe 13th.
I'm attaching a copy of the last contract amendment we brought to
council as an example. We will handle the exhibit and the memo to
council.
Thanks.

Keith, we have looked at the possibilities for reworking the project by
narrowing the roadway and constructing the bridge in phases allowing
maintenance of traffic on the existing roadway and bridge. We have
developed construction cost estimates for the revised pavement width
(41-foot and 37-foot back to back) and an estimate for staging the
bridge construction.
In order to accomplish the design changes requested, without modifying
the current alignment, we have identified the following design fees:
Grapevine Creek to Belt Line Road -
Basic Plan Modification - $27,500
Redesign Storm Line B from Approx. Station 5+00 to end (including
associated 24-inch Water Line crossings) - $7,500

Coppell Road to Grapevine Creek -
Basic Plan Modification - $24,000
Bridge Plan Modification (first structure) - $12,500 Second Bridge Plan
(structure after demolition) - $30,000 Sequencing Schematic and
description - $5,000
This effortwill take approximately 6 weeks to accomplish.
As noted in the estimates, we anticipate saving approximately $160,000
in the roadway costs by reducing the width from 45-feet wide to 37-feet
wide. The bridge costs are estimated to increase by approximately 50%
due to the sequencing and staging of the construction. Note that the
construction time will also increase.
I would be happy to come by at your convenience and discuss the various
issues associated with the project re-design. Please let me know that
you receive this message. Thanks!
