Subject: Additional Services for Lancaster Construction Phase Services
Mr. Leuschen:
On December 15, 2005, we presented to you and Linda Young a list of 5 items as additional services
to the May 16, 2005 contract. The 5 items are:
1. Additional Survey for Frank Kent
2. Coordination/Design Changes for Art Work within the Medians
3. Additional Design Changes
4. Additional Site Visits
5. Work for 1933 UGE
At that meeting,and additional meetings,we decided that a supplemental would not be requested for
Items 1 and 2 at alis time, but could be revisited at a later date.
Additional Design Changes
The May 16, 2005 contract states that TCB will perform 5 Change Orders. TCB performed 10 design
changes between Mat and January based on requests from the City of Fort Worth and TxDOT. These
design changes are listed below:
• Revised removal sheets and grading sheets to leave existing sidewalk in place and
remove additional curb and gutter based on TxDOT request.
• Removed retaining wall at T&P Warehouse.
• Removed Trench Drain at T&P Warehouse and redesigned portions of Storm Drain Line
B.
• Addition of Fiber Optic Conduit between Monroe and Jennings.
• Better data was collected on some utilities after the design and thus Line A9, Lateral B1,
Lateral D1, and Lateral F2 were revised to avoid conflicts with utilities.
• Storm Drain revisions for Laterals B1, 64, D1, F2, F3, G1, and G4 were made based on
TxDOT request so that the storm drain trench would cross the 1933 UGE conduit
perpendicularly instead of at a skew.

• Prepared plans to replace and coat an existing sanitary sewer manhole north of the Post
Office based on request by the City of Fort Worth. Upon visiting the site and coordinating
with the City of Fort Worth, a Field Change was made to leave the existing manhole in
place, since it was recently installed.
• Entrances to P.O. Parking Lot had to be redesigned to match proposed parking lot grade.
The change was necessary since the grade of the post office parking lot was requested to
be modified by the City of Fort Worth after the roadway design plans were prepared.
• Removed steel curb drain at northeast corner of Throckmorton and 15th Street. The steel
curb drain was designed to drain storm water from the property to the east of
Throckmorton and north of Lancaster. The curb drain in this location was not aesthetically
pleasing, and thus it was removed. A drop inlet and storm drain were designed to drain
the subject area.
• A Storm Drain and Sanitary Sewer were redesigned at 15th St. and Throckmorton to avoid
a conflict with an electrical conduit used to power billboard and gate, based on a request
from the City of Fort Worth.
Although the number of design changes listed above exceed the contracted amount, TCB is not
requesting additional services for the said design changes.
TCB is, however, requesting additional compensation for three additional design changes to the
contract. These design changes include redesigning storm drain Laterals F2 and F3, redesigning
storm drain Laterals G3 and G4, and modifying the curb location west of West 15th Street along
Lancaster Avenue. Laterals F2 and F3 were modified to prevent the storm drain crossing TXU's 138
KV line. Laterals G3 and G4 were modified to go around a TXU utility duct, and a gas-line whose
elevations were not previously known. The curb of Lancaster is to be moved 6-in to the north to
prevent a conflict with TXU's vault between West 15th Street and Houston Street. The anticipated
effort to perform the 3 design changes is$7,965.
Additional Site Visits
The May 16, 2005 contract stated that the cost for the site visits was determined based on the quantity
of site visits. To date,there have been 34 site visits/meetings attended, which exceeds the contracted
amount of 30. TCB requests $1,200 for the meetings attended that exceeded the contract and for
anticipated meetings.
Work for 1933 UGE Conduit
The City of Fort Worth agreed to protect TXU's 1933 duct bank along the south side of Lancaster. To
assist TXU in protecting the duct bank, the City of Fort Worth asked TCB to provide two different sets
of plan sheets, one for the City of Fort Worth, and a second for TXU, to show the top of 1933 conduit
and the proposed bottom of HMAC base above the duct bank. Two sets of plans were prepared so
that if TXU could not provide the work to protect the line, then the City of Fort Worth could issue the
plans to a contractor to provide a portion of the work.
The work/coordination required to prepare the plan sheets were not covered in the original
construction phase contract. TCB has prepared sheets showing the bottom of base along the TXU
distribution line for Lancaster, Monroe, Jennings, Throckmorton, 15th Street, and Commerce/S. Main.
TCB request$15,735 for compensation for preparing the plans and for ongoing coordination efforts
with TXU.
