Proposed Work Scope for
MFK Consulting Services to Assist TranSystems Corporation
Consultants in Resolving Sewer Pipe Issues for
The City of Forth Worth, TX
Prepared by
Melvin F. Kanninen, PhD
Submitted on
July 14, 2004
Introduction
MFK Consulting Services(MFKCS)has reached a general understanding with
TranSystems Corporation Consultants (TSCC)on the assistance that MFKCS can provide to
TSCC in the Village Creek sewer construction project that it is conducting for the City of
Fort Worth(CFW). The discussions that have led to this understanding have centered on the
technical issues associated with the pipe material selection process that has so far precluded
this project from being initiated. Based on previous knowledge of the mechanical behavior
of sewer pipe, and on the testing that can be conducted to quantify this behavior,MFKCS
believes that it can be of direct assistance in achieving a prompt resolution of the problem.
Background
It is clear that the basic impediment to the initiation of CFW's Village Creek sewer
project is an intertwined combination of technical issues and conflict resolution. There are
two over riding-- and directly conflicting--concerns. First,because the CFW is under great
pressure to complete the project,any further delays in initiating it will be difficult for them to
accept. Second,because it appears that a wide range of pipe types will be proposed for this
project by contractors who will utilize vendors possibly having significantly different
capabilities for making pipe,time is needed to develop a fair competition that will at the
same time assure that the City will have a credible product installed.
Because it will additionally serve to provide a sound platform for awarding contracts
for future sewer projects, the approach that is most appropriate for initiating CFW's Village
Creek sewer construction project is one that provides the most reasonable compromise
between a swift resolution and one that requires more time but provides a technically
satisfactory resolution of the problem. The assistance that MFKCS can provide to TSCC in
developing and implementing this compromise approach is as follows.

EXHIBIT A
Proposed Work Scope
Five tasks are proposed to be performed by MFKCS under the general supervision of
TSCC in support of their work on the CFW's Village Creek sewer construction project. The
consulting hours and other costs needed to perform the work in each of these tasks are
estimated in a tabulation that appears on page 4.
Task 1: Develop Supplemental Testing Program
Starting immediately, a thorough search will be made to identify, acquire and
assimilate all pertinent ASTM and other standards now available for testing sewer pipe and
sewer pipe materials. This review is expected to lead to the development of a small—but
comprehensive—set of standardized tests that can be included in a specification document.
This set of tests will be selected to effectively screen all of the various pipe products that are
likely to be included in the contractor bids that will be given to the CFW for its Village Creek
project, and for all foreseeable future sewer projects,without unnecessarily burdening the
pipe vendors.
A draft version of a complete specification document embodying this information
will be provided to TSCC for their review on August 26,2004. A final version of the
specification incorporating TSCC comments and other input is to be submitted to the CFW
for their disposition by August 30,2004.
Task 2: Identify Suitable Independent Testing Organizations
In parallel with the identification of a set of effective screening tests,an effort will be
made to identify the best qualified independent testing organizations that can perform the
tests on pipe provided by the vendors. Candidate organizations are Stress Engineering
Services,Houston, TX; the Southwest Research Institute, San Antonio,TX,the Trenchless
Technology Center at Louisiana Tech University, Ruston,LA; and MACTEC, Inc., in Ft.
Worth, TX. Contacts will be made to assure that these organizations (and possibly others)
have the requisite testing capabilities,and that they also could conduct the testing in an
expeditious manner. Site visits to the leading candidate organizations will be made to assure
that the requirements of this program can be fully met.
Appropriate contact information on at least one testing organizations meeting these
requirements will be provided to TSCC for their negotiation with them. This identification will
be provided by August 23,2004.
Task 3: Review and Critique Data from Pipe Manufacturers
A critical assessment will be made of the technical data developed by the manufacturers
on the performance of their pipe. These data are expected to be available for review in mid
September; i.e., at the pre-bid conference. Participation in the pre-bid conference is also
anticipated to assist,as needed, in the presentation of the supplemental testing program plan.

EXHIBIT A
Task 4: Observe and Assimilate Testing Conducted by Independent Organization
At an appropriate time after testing has commenced, a visit to the independent testing
organization that has been selected by TSCC will be made to observe their procedures,
review preliminary data, and,to the extent possible,help expedite their progress. At the
completion of the testing, a detailed review of the data that have been generated will be
conducted, and recommendations made to TSCC in regard to the acceptability of the selected
pipe vendor for them to provide to the CFW.
Task 5: Develop Long Range Comprehensive Pipe Qualification Plan
While the work in tasks 1 to 4 will be aimed specifically at the Village Creek project,
this work will also provide a foundation for a general procedure that CFW can utilize in
future construction projects. The work in this task which will be carried out in parallel with
the preceding tasks,will include(i)making systematic contacts with progressive
municipalities(e.g., The City of Houston, TX; The County of Los Angeles, CA)to learn
about the strengths and weaknesses of their systems, (ii)identifying key technical issues
together with strengths and weaknesses in the CFW's planning, contracting and acquisition
systems, (iii)discussing the"lessons learned"in this activity with TSCC and the CFW,and
(iv)if warranted by the above, scoping further work needed to develop an enhanced
approach for sewer and other projects that the CFW could adopt. The anticipated product of
this task would be a well documented set of procedures that would streamline and
standardize the qualification and supervision of CFW contractors for future sewer(and other)
city projects.
Cost and Time Estimates
The cost estimates by task for MFKCS participation in this work are provided in the
following tabulation. These estimates include the real and actual costs of travel approved by
TSCC, and of the acquisition of pertinent reference material, as needed and approved by TSCC.
The time costs in this tabulation are entirely those of Dr. Melvin F.Kanninen, and are based on
the following billing rates:
Consulting time ..................... $200 per hour
Unproductive travel time ........... $100 per hour
Depositions and live testimony .... $300 per hour
The period in which the work that is described in Tasks 1 and 2 above is performed is
expected to extend from July 15 through August 31,2004. While the work in Tasks 3 to 5 will
be initiated in this period,their completion date cannot be estimated at this time.
