Sandy Lake Road Project ST 93-02 Change Order #6
Attached to this memo is Change Order 06 in the amount of $22,590.48 for a structure to
transition proposed drainage facilities beneath an existing 16" gas transmission llne that runs
north/south in Moore Road and crosses Sandy Lake Road. During the design of Sandy Lake
Road, it was assumed that the gas line would be relocated by TXU at their cost. However,
about the time that the Sandy Lake Road project was bid in 1998, it was determined that
TXU's easement superceded our right-of-way and therefore we would be responsible for the
cost to lower the gas line. Attached to this memo, is a copy of an estimate from Lone Star Gas
indicating that the cost to lower the transmission line would be approximately $318,700.
Because of the expense to lower the gtas line and because it would be a City cost, other options
were explored. The option addressed by this change order is one that I recommended.
The $22,590.48 is substantially less than the $318,700 requested by TXU to lower their
gasline. However, I have also received an invoice from TXU Lone Star Pipeline Company
indicating that they are seeking reimbursement of $38,556.64 for their work involved with
their original design to lower the gas line in 1998. There has been some conversation with
TXU Lone Star Pipeline concerning that invoice, but at this time it appears likely that we will
be required to pay that invoice. Therefore, our total cost involved with the gas line, inclusive
of Change Order 06 and the invoice from TXU Lone Star Pipeline, is $61,147.12. This is
$257,552.88 less than what it would have cost us to lower the gas line (approximately 19% of
the cost to lower the gas line).
Staff recommends the approval of Change Order 06 in the amount of $22,590.48 to build a
transition structure near Moore Road/Sandy Lake Road to avoid relocating the 16" Lone
Star gas main. I also will be processing the invoice from TXU in the $38,556.64 to Finance
for payment.
If you should have any questions or need additional clarification please contact me.

Dear Mr Saunders:
Enclosed are three(3) copies of cost estimates and plans for
the relocation of approximately 720 feet of 16-inch Line F, and
abandonment of approximately 700 feet of existing 16-inch pipe.
The total estimated cost for this alteration is $318,700.00. This
estimate is subject to review after 60 days. Please note that due
to the numerous construction obstructions, the estimate involves
considerably greater distance and therefore much higher cost than
would normally be the case(see the enclosed explanation sheet).
Approval of the proposed pipeline route shown on the attached
drawing is necessary prior to the start of construction by Lone
Star Pipeline Company. Approval shall include confirmation Chat
existing and proposed features along the proposed pipeline route
are shown completely and correctly.
Proposed and existing features shown, including land usage,
grades, streets, drainage structures, water lines, storm sewers,
etc., along the proposed pipeline route are based on the best
information available Co Lone Star Pipeline Company. I~ the
features shown are incorrect or new information is available,
please advise as soon as possible so plans can be revised
accordinglY.
Should you wish to proceed with alteration of our facilities
as shown on the attached drawings, please so indicate by signing
the drawings next to the title block and return one approved copy
to my attention.
Please furnish this office authorization for reimbursement of
the actual cost incurred on this project. When this authorization
is received, scheduling of the work can proceed.
Upon completion of the alteration work, you will be furnished
