<br />In the Study and Report Phase, crews will be dispatched to <br />review all 347 manholes proposed in the referenced summaries <br />for repair and tb confirm the repairs actually required. Each <br />manhole will be accurately spotted on the I" = 100' aerial base <br />map. The manholes will be measured as to depth; the repairs <br />required will be listed; drop lines, if any, will be noted. We <br />estimate that 26 crew-days will be required for this phase of <br />the work. <br /> <br />Based upon this preliminary field investigation, the ENGINEER'S <br />opinion of probable construction cost will be corrected, if <br />found necessary, and a new listing of repair types, reflecting <br />technological changes, current costing, and current field <br />conditions, will be prepared. The above information will be <br />gathered into a summary report and recommended project. <br />Meetings with City staff will be conducted, as necessary, as <br />the preliminary project progresses, and a final meeting will be <br />held to review the completed report. Ten copies of the <br />completed report will be provided. In addition to the field <br />time specified above, 242 manhours of office time are <br />preliminarily estimated to be required in this phase. The fee <br />for this phase is based upon section 5.1.2. herein and it is <br />understood that the manhour projections contained herein are <br />preliminary estimates only. <br /> <br />3. Preliminary Design and Field Survevs Phase Services are <br />further described as follows: <br /> <br />Manholes which do not require excavation around the exterior <br />of the manhole for repair will be presented to construction <br />contractors in the bidding phase via the I" =100' aerial <br />photography previously mentioned. Each manhole will be <br />spotted thereon, together with a note indicating the typical <br />repair required. In certain instances, namely the manholes <br />which must be completely reconstructed, the contractor will <br />require additional information to prepare his bid, such as <br />whether or not the manhole is located in pavement which must <br />be repaired, the location of adjacent utilities, and surrounding <br />working conditions. In the case of these manholes, an B" x B" <br />inset map will be prepared for each manhole. The base for <br />this map will be the previously mentioned aerial photography, <br />which will be blown up to 1" = 20' or similar scale. Field <br />survey notes will be plotted directly on the aerials to indicate <br />surrounding utilities, limited working area, pavement repairs <br />required, etc. Copies of these inset maps will be provided to <br />the local utilities, including the City, Lone Star Gas, Texas <br />Utilities, Southwestern Bell and Cooke Cablevision, to locate <br />any underground utilities which might be in conflict with the <br />proposed repair work. It is anticipated that the a" xB" inset <br />drawings will be mounted in groups on 24" x 36" sheets of <br />mylar for inclusion in the normal construction drawings, or <br />bound as a separate volume. <br /> <br />Page 16 of 19 Pages <br />
