Weiss, P.E. City of Ft. Worth 1000 Throckmorton Street Ft. Worth, Texas 76102 Reference: Rosedale Street Drainage at Beckham Pl. Dear Mr. Weiss: Enclosed please find a copy of the proposed fee and manhour requirements to accomplish the modifications to the proposed drainage system along Rosedale Street. An evaluation of the existing system will be required in order to determine the capacity of the old system and the total storm discharge flowing to the system. Design of the new system will assure that the new system is not being overcharged, thus creating problems for the new drainage system. Finally, the plan sheets, quantities and estimate will be updated and re-issued for construction. Hours and mileage have been added for travel to meetings at your offices. Please call me at 972-406-6961 if I can be of further assistance. 3 Sincerel Gre 1 o g g Senior Project Manager 4 I URS Corporation Graystone Centre 3010 LBJ Freeway, Suite 1300 Dallas,TX 75234 Tel: 972.406.6950 Fax: 972.406.6951 ATTACHMENT A SCOPE OF SERVICES TASK 1 Develop temporary drainage solution, without engineering calculations, for Fire Station construction south of Rosedale Sta. 10+500.
