RE: Request for Additional Engineering Compensation
Dear Mr. Argomaniz,
J. B. Davies, Inc. (JBD) maintains a contract with the City of Fort Worth to design storm
water system improvements, develop construction plans and proposal documents for the
Lost Creek Phase II Drainage Improvement Project, Lost Creek Phase II project
;onsists of storm water capacity improvements to serve three unique locations in
westerly Fort Worth located on the following streets: Ben Creek Court, Blue Creek Court
and Powderhorn Road.
Preliminary designs of all three project locations were developed during the original Lost
Creek Project (Phase I) completed in May 2003 by JBD. Due to funding limitations it
_ was necessary to omit the Lost Creek Phase II drainage system improvements from the
original project. J. B. Davies, Inc. was contracted by the City of Fort Worth to complete
the development of construction plans and contract documents for the previously omitted
Lost Creek Drainage Improvements into a Phase II Project. Both the City Engineer
(Richard Argomaniz) and JBD's Project Engineer (David Mathiesen) were under the
impression that the preliminary design was approved by the City in the original Lost
Creek Project and Phase II started in the final design stage. During the development of
the final design a variety of issues arose that resulted in additional consultant
involvement and warrants consideration for additional compensation by Engineer. The
following details additional work performed by engineering consultant (JBD) that justifies
additional compensation for Lost Creek Phase II Drainage Improvement Project:
• Consultant conducted modeling analysis and modified Blue Creek Court plans,
specifications and cost estimates to account for 25-year water level at St. Marys
creek during the 100-year design storm event to provide the highest possible
benefit.
• Met with property owners affected by revised design of Blue Creek improvements
to discuss options to improve system and how the design would affect the
respective property owners.

• Based on property owner interviews, City decided to eliminate the Blue Creek
Court drainage improvement design from the project. Consultant modified plans,
specifications and cost estimates as directed by City.
• City requested consultant to provide a level of service analysis to evaluate
benefit versus cost for proposed drainage improvements at the Blue Creek
project site. The level of service analysis included the following options: no
improvements to current drainage system, improving drainage system within the
street right-of-way and improving the drainage system (including private property)
to provide the highest possible benefit. Consultant provided this level of service
analysis (including cost estimates for options) to the City.
® City decided to include Blue Creek Court back into the project. Consultant
modified plans, specifications and cost estimate to include Blue Creek drainage
improvements based on City's decision to provide drainage improvements solely
within the street right-of-way.
• Based on discussions with property owners, modified Ben Creek plans to include
a grading plan at outfall into golf course to eliminate storm water ponding.
• Adjusted Powderhorn Road drainage improvement design to avoid potential
conflicts with existing sanitary sewer services.
As a result, JBD is requesting additional compensation of the amount of $i3OOO.00 to
account for additional services provided to develop the final design of the Lost Creek
Phase II Drainage Improvement Project,
Sincerely,
J. B. DAVIES, INC. ENGINEERS AND SURVEYORS

SUBJECT: Authorize Amendment No. 1 in the Amount of $7,000.00 to City Secretary Contract No.
30976 with J. B. Davies, Inc., for Lost Creek Phase 2 Drainage Improvements (Project No.
00087)
RECOMMENDATION:
It is recommended that the City Council authorize the City Manager to execute Amendment No. 1 to
City Secretary Contract No. 30976 with J. B. Davies, Inc., in the amount of $7,000.00, revising the total
cost to $31,100.00.
DISCUSSION:
The 2004 Capital Improvement Program (CIP) included funds for the design of storm drain facilities to
alleviate recurring flooding problems in various locations. On November 30, 2004, the City Manager
executed administratively an engineering agreement with J. B. Davies, Inc., for the design of the Lost
Creek Phase 2 Drainage Improvements. The design resulted in the recommendation to install storm
drain facilities at the following locations:
• Blue Creek Court from west of Snow Creek Drive to Cul-De-Sac.
• Ben Creek Court from east of Lost Creek Blvd to South of Dead End.
• Powderhorn Road from Lone Pine Road to Little Valley Road.
The existing drainage system in the Blue Creek Court location does not have adequate capacity to
carry the discharge resulting from the 100-year storm in accordance with City standards. In addition, the
flood elevation of the creek where the system discharges, limits the level of improvements that can be
attained. In order to improve the drainage facilities it will be necessary to relocate various permanent
structures adjacent to the existing drainage easement. Engineering studies have indicated that the
benefit attained from this plan does not justify the cost of replacement of the conflicting structures. Staff
has determined that the highest possible benefit can be attained by improving the facilities within the
available right-of-way.
Amendment No. 1 for the subject engineering agreement will provide the following:
• Consultant will conduct hydraulic modeling analysis and revision of Blue Creek Court plans, specifications and cost estimates to attain
maximum benefit from installation of drainage facilities within the public right-of-way.
• Develop a grading plan at the outfall into the golf course of the Ben Creek Court drainage system to eliminate storm water ponding.
J. B. Davies, Inc., proposes to perform the necessary design work for a lump sum fee of $7,000.00. City
staff considers the fee to be fair and reasonable for the scope of services proposed.
