CLOTTEY <br />ENGINEERING, INC. <br />Shawn Napier, P.E. <br />City Engineer <br />City of Paris <br />150 SE 1 S` Street <br />Paris, TX 75460 <br />RE: Modification af Railroad Flat Car to Pedestrian Bridge <br />Dear Shawn, <br />February 11, 2011 <br />As you know, the information needed for the design detaiis for the zailroad flat caz was not obtainable at the <br />beginning because the flat car was located out of State. Hawever, in order not to delay the design we used <br />phatographs to develop most of the design. During subsequent sites visits after the flat car was shipped to <br />Paris closer examinations of the structural components were made. It was during these examinatians that it <br />was determined that some of the sizes and lacations of some of the structural members were not correctly <br />detailed. <br />These variations require that additional shvctural modifications be made to provide the addirional bracing to <br />ensure the flat car will functron adequately as a pedestrian bridge. Specifically, more steel stiffeners need to <br />be added to the webs of the suppart beams and cover plates need to be added to the flanges of the support <br />beam at each end of the bridge. E~en though tlae changes were held to the minimum required they are <br />necessary and labor intensive on the part o f the contractor. <br />If the bridge had been available for examinatian prior to beginning the design these stiffeners and cover <br />plates would have been included in the initial design and the contractor would have reflected that wark in <br />his bid price. Therefare, I believe that the addition of this work now is not adding any cost that would not <br />have been included if this work was included in the original bid. <br />In conclusion, I believe that the contractor's requested change order price of $6,124 is in line with the work <br />to be performed. <br />Please let me know if you have any questions or require additional inf"ormation. <br />Sincerely, <br />Clifford lottey, Ph.D., .E. <br />Yroject ger <br />Cc: Mike Donnan, P.E., <br />Hayter Engineering, Inc., Paris, TX. <br />41'7_004_01170.
