AGREEMENT
THIS AGREEMENT, dated this day of 1963,
by and between the City of Jefferson, Cole County, Missouri (City), and
Horner & Shifrin, Consulting Engineers, St. Louis, Missouri (Consultants),
covers engineering services to be rendered by the Consultants relating to
a sewer rehabilitation program within the City.
SCOPE OF ENGINEERING SERVICES
The sewer rehabilitation program is aimed at the determination of
those specific sections and components of the existing sewer system which
are in need of repair or reconstruction, and the scheduling of and arrange-
ments for the performance of the required repairs and reconstruction,work.
The engineering services covered under this Agreement will consist of field
investigations, recommendations as to the scope of the repair work to be
performed, and as to whether the work could be performed by City forces
or by contractors, preparation of plans and specifications for major work,
if necessary, negotiation with contractors for the performance of the re-
pair work, supervision of the construction work as required, and establish-
ment of procedure and forms for the maintenance of records. A more
detailed description of the scope of the engineering services to be rendered
is incorporated in the attachment entitled "Procedure for Sewer Rehabilita-
tion Program", which is part of this Agreement.
RESPONSIBILITY
The Consultants shall assume responsibility for the direction and
guidance of the sewer rehabilitation program, in keeping with the normal
functions and responsibilities assigned to consulting engineers. The City
shall provide such services as defined hereinafter, upon the request and
under the direction of the Consultants.
ASSIGNMENT OF PERSONNEL
The Consultants shall assign one qualified person as their field
representative, who shall direct the day to day activities required for the
field investigations. It is anticipated that after the procedures for the
1
field investigations are fully understood by the remaining field personnel,
full time direction by the field supervisor will not be necessary. However,
it is understood that the field supervisor will be locally available for con-
sultation whenever field work is progressing concurrently with other field
work under his direction relating to the design and construction of the
facilities included in the current sewerage bond issue program. When the
field supervisor is not engaged in the direction of work related to design
and construction wool tons NOW his services shall
be It is understood that City
personnel, working under the direction of the Consultants, may be utilized
to expedite the work.
pEVOr to To rIac -5f-rr� - R�fla jLi rr�r�or/ Ifp?,�:.r'�N1,
The City will assign at least one City employee who is intimately
familiar with the existing system to work under the direction of the field
supervisor. The Consultants will supply the remaining field personnel
necessary to conduct the field investigations should City personnel not be
available.
It is understood that upon the request of the field supervisor, the
City will furnish the labor and equipment required to open manholes, enter
sewers, ventilate sewers, clean sewers, and perform such other functions
as required to develop the needed field data. The City shall, upon recom-
mendations of the Consultants, contract for services relating to the use of
closed circuit television or similar devices, should the use of such devices
prove to be necessary.
It is further understood that the Consultants' office personnel and
facilities may be required upon occasion, and will be available for assist-
ance when necessary. The maps and records of the City shall be available
to the Consultants at all times and the Office of the City Engineer shall
render reasonable assistance when called upon.
TIME OF COMPLETION
It is possible that the Sewer Rehabilitation Program and the services
rendered under this Agreement may progress over an extended period of
time. Since it is impossible to foresee the scope of the specific repairs
and rehabilitation work required, no time of completion can be set. How-
ever, it is understood that the Consultants will make every reasonable
effort to expedite the work.
METHOD OF PAYMENT
For the services rendered under this Agreement, the City shall
reimburse the Consultants on the basis of the actual man-hours spent by
2

PROCEDURE
FOR
SEWER REHABILITATION PROGRAM
JEFFERSON CITY, MISSOURI
The procedures outlined herein relate to field investigations, minor
repair work, and major repair work as required to rehabilitate the existing
sewers in Jefferson City.
FIELD INVESTIGATIONS
The field investigations shall proceed as expeditiously as possible,
concentrating on those existing trunk sewers which are known to require
the most extensive work. Since certain of the required observations de-
pend upon the occurrence of rain, it is possible that the total accumulation
of the required data might not be accomplished for several years. The
general suggested procedure, which may require modification as the in-
vestigations progress, is outlined as follows:
1. Starting at the upper end of a trunk sewer, observe whether
sewage flow is unobstructed between successive manholes.
If the sewer has no bends between manholes, lamping the
sewer may be sufficient for this determination. If the
flow appears to be obstructed, the obstructions should be
removed. Where possible, City personnel will be called
upon to remove any obstructions.
2. After unobstructed flow is obtained, observe and record
the depth of flow during dry weather. Depth should be
recorded at critical points of flow at as many hourly
periods as the work schedule permits.
3. Flow observations also should be made during periods of
rainfall runoff. Some nominal increase in sewage flow
1
may be expected. However, if the flow increase is sub-
stantial, runoff probably is entering the sewer from roof
drains, areaway drains, or other illegal connections,
from leaking manholes, frames, and covers, or from
breaks in the sewer. In such cases, investigations should
be made of potential illegal connections. If no significant
illegal connections are found, further investigations will
be required as to the probability of a broken sewer.
4. The isolation of specific breaks in a sewer may sometimes
be done by several means. Under ideal circumstances, it
might be possible to locate breaks by visual observation
from a manhole. The use of smoke bombs has been said
to be effective for this purpose. Since the investment re-
quired for the smoke equipment is small, it would be
appropriate to try this method to determine its effectiveness
in Jefferson City. Until these two methods are explored
thoroughly, it would not appear necessary to adopt the more
expensive methods, such as closed-circuit television or
similar methods.
5. Comprehensive data should be recorded for each manhole
and for each length of sewer. The recorded data preferably
should be in a uniform form, for convenient reference, and
should at least include the following:
a. Location, with sketch if appropriate.
b. Size of all manhole inlets and outlet.
c. Sources of flows from all inlet lines (if practicable).
d. Depth of sewage flow at main inlet and outlet, for
as many hourly periods as practicable, and for
both dry weather flow and rainfall runoff flow.
e. Observations regarding type and condition of man-
hole cover and frame, together with solidity of
setting, condition of manhole walls, whether
leakage is apparent, septicity of sewage, unusual
odors or fumes, dates of observation, and any
other pertinent data.
f. Record of corrective measures taken, and recom-
mendations for further work.

MINOR REPAIRS
47 000
Minor repairs (say less thalwa in magnitude), if urgent, should
be made without delay. Less urgent minor repairs, which would not create
nuisances or public health hazards if delayed, should be scheduled and
given an appropriate priority. All repair work, no matter how minor,
should be performed as expeditiously as possible, since quick action might
well prevent major repairs from being required at a later date.
MAJOR REPAIRS
The extent of the repair work necessary in sewer systems in many
cases is impossible to define in advance of actually opening an excavation
to expose the sewer. One of the functions of the field investigations is to
attempt to define the extent of the necessary repair work. This requires
the exercise of objective judgment as to whether the repairs are of an ex-
tent which could be best performed by a private contractor rather than by
City personnel. It should be recognized that the intimate knowledge of
City personnel often can be best and most efficiently utilized in minor re-
pair work and in definitive activities relating to work of greater scope to
be performed by others.
It will not always be possible to define major sewer repairs or
reconstruction to a degree which will allow competitive bidding by con-
tractors on a unit price or lump sum basis. The alternative is to
negotiate with a contractor on a cost-plus basis. In such cases, accurate
cost control is mandatory, and every effort should be made to have a day-
by-day accounting of the work performed and the cost thereof. It also is
important to have a responsible representative of the City at the job site
to protect the interests of the City and to direct the work.
