<br />Exhibit A <br />to <br />Agreement Between OWNER and ENGINEER <br />for <br />Professional Services <br /> <br />Further Description of Basic Engineering Services and Related <br />Matters <br /> <br />1. This is an Exhibit attached to, made a part of, and <br />incorporated by reference into the Agreement made on <br />November 14, 19BB, between the City of Paris (Owner) and <br />Hayter Engineering, Inc. (Engineer) providing for professional <br />engineering services. The Basic Services of Engineer as <br />described in Section 1 of the Agreement are amended or <br />supplemented as indicated below. <br /> <br />2. Study and Report Phase services shall include the following: <br /> <br />The OWNER will secure by separate contract aerial photography <br />of the entire City, at a scale of 1" = 100', but of sufficient <br />quality such that specified areas can be further enlarged to I" <br />= 20'. <br /> <br />The City's Infiltration/Inflow Study identified approximately <br />1049 manholes in the system. Each of these manholes was <br />inspected approximately 12 years ago, and detailed reports <br />recommending repairs were prepared at that time. It is <br />anticipated that some of these repairs have been accomplished; <br />likewise, some manholes which were marginal at that time will <br />have further deteriorated. Different repair technologies <br />available today may otherwise alter certain of the repair <br />recommendations. <br /> <br />Ninety-eight (98) priority manholes are included in this <br />contract. All Priority #1 and #2 manholes in the original report <br />are included herein, as well as all Priority #5 manholes. <br />Manholes which are on lines to be replaced are to be deleted. <br />It is anticipated that early in the design phase, coordination <br />will be undertaken with the Public Works and Engineering <br />Departments, and that certain manholes which have already <br />been repaired, may be removed from this list as a result of <br />those repairs. <br /> <br />In summary, it is anticipated that 347 manholes will require <br />repair of one nature or another, and that 90 will require <br />complete rebuilding, These manholes are identified on a list <br />entitled "Summary of Manhole Repairs to Remove Inflow" which <br />was included as an appendix to a report entitled "Proposed <br />Methodology for Development of Construction Drawings and <br />Specifications and Procurement of Construction Contractors for <br />Manhole Rehabilitation" dated September, 19BB. <br /> <br />Page 15 of 19 Pages <br />
