SCOPE OF SERVICES Our scope of services for the two major components as described in your request are as follows: Remediate Leachate and Segment 3 cell 2 Drainage Issues The work will be performed on a time and material bases per the attached fee schedule. The hourly rate for the entire crew and equipment is $878 per hour. Materials and subcontractor work will be billed at cost plus 10%. We anticipate approximately $4,500 in material cost if the 10" valve needs to be replaced. I have also attached the estimate of $2,500 from Florida Jet Clean to video camera and investigate the 10" control valve. In additional the price to jet clean the entire length of the 10" leachate collection system (approximately 1,300 -ft) would be $2,475. Our budget includes two days of field time for pumping liquids and investigating the 10" valve which will require a 4" branch saddle and valve be installed on the landfill side of the existing 10" valve to gain access for the video camera. Additional Landfill Gas Collection 1. Extended 600 feet of horizontal collection trench as directed. The price per foot will be performed at the contract price of $67.00 less $5.20 per foot for owner supplied perforated pipe. The total for this task is $37,080 (600 feet at $61.80). 11260 Roger Bacon Drive, Suite 300, Reston, VA 20190 1 703-471-6150 Fox 703-709-83790 Mr. Martin J. Lewis May 13, 2021 Page 2 BUDGETARY ESTIMATE SCS -FS estimates the services described in this proposal for the Remediate Leachate and Segment 3 cell 2 Drainage Issues can be performed based on a time and material budgetary cost of $24,869.
