PACRU EEC'ED FWE98011 amendment3 M-390 reV1.x1s FoFTWOFTH - MEMORANDUM TO: A. Douglas Rademaker, Director DOE and Mike Groomer, Assistant City Manager FROM: Mike Domenech DATE: April 24, 2000 RE: DESIGN FEE AMENDMENT NO. 3 TO MAIN 170 DRAINAGE AREA SANITARY SEWER MAIN 226 AND 227, LATERAL 1616 AND 1635 REHABILITATION DOE NO. 2765 The proposed amendment will reimburse J.B. Davies, Inc., for the additional engineering services that will be provided on the project as requested by the City. Subsequent to television inspection of the project it was revealed that lateral L-1635 had severe defects and was experiencing infiltration. As the line is contiguous with the exist- ing plans under development, it was decided to include these additional 348 linear feet of sanitary sewer line to the scope of the project to correct this condition. Upon direction from City staff J.B. Davies, Inc. conducted additional survey and has augmented their design submittal to reflect this additional linear footage. J.B. Davies, Inc., has requested a fee of$3,893.07 for the additional services to be pro- vided thereby increasing the contract fee from $438,540.44 to $442,433.51. I believe this fee is fair and reasonable for the additional services that were provided. Please authorize the additional design fee by your signature on the attached contract amendment form. cc: Tony Sholola, P.E., Program Manager Berdena Hamilton, Water Department Dan Pepon, Water Department MEMO 2763 i ENGINEERING DEPARTMENT THE CITY OF FORT WORTH * 1000 THROCKMORTON STREET * FORT WORTH, Texas 76102-6311 (817) 871-7941 * Fax (817) 871-7854 ej Printed on recycled paper
