LOUIS , MISSOURI, RELATING TO A SEWER REHABILITATION PROGRAM WITHIN THE CITY OF JEFFERSON, MISSOURI. BE IT ORDAINED BY THE CITY COUNCIL OF THE CITY OF JEFFERSON, MISSOURI, AS FOLLOWS : Section 1. The Mayor and the City Clerk of the City of Jefferson, Missouri, are hereby authorized and directed, for and in the name of the City of Jefferson, Missouri, to execute a written contract with the firm of Horner & Shifrin, Consulting Engineers, St. Louis, Missouri , relating to services to be rendered by that firm in connection with a sewer rehabilutation program within the City of Jefferson, Missouri . Section 2. The aforementioned written contract shall read in words and figures as follows: October 23, 1963 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 the Consultants' personnel on work related to the sewer rehabilitation program. The hourly rates applicable to the various classes of the Con- sultants' personnel shall be as follows: Class of Personnel Hourly Rate Associates $10. 00 Principal Engineers 9. 00 Engineers 8. 50 Draftsmen 7. 50 Field Supervisor 7. 50 Field Personnel 5. 40 Clerical Personnel 4. 00 Surveying Party It is anticipated that the City surveying personnel will be available. However, should it be necessary to utilize the surveying personnel of a local engineering firm, The Consultants shall be reimbursed upon the basis of the actual fees plus 10 per cent. These rates shall include salaries, overhead and profit. In view of rising costs, these fees shall be subject to escalation at yearly intervals upon a basis to be mutually agreed upon by the City and the Consultants. In addition to the hourly rates for personnel, the Consultants shall be reimbursed at actual cost for all out-of-pocket expenses, such as travel and living expenses, when applicable, supplies and telephone calls which will be directly related to the sewer rehabilitation program.

HORNER & SHIFRIN CITY OF JEFFERSON, MISSOURI Consulting Engineers BY �// BY Partner Mayor Attest City Clerk 3 HORNER & SHIFRIN Consulting Engineers St. Louis, Missouri October 23, 1963 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. 2 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. 3 Sea*ion 3.
