Exhibit A <br /> SCOPE OF WORK <br /> (Describe the scope of wark by breaking down the project into major work elements or phases. <br /> Further divide the major work elements or phases into tasks, identify proposed staff positions to <br /> accomplish the tasks, and show direct salary cost. Estimate the staff hours to accomplish the <br /> task, and calculate the direct cost. A sum of staff hours by position and direct salary cost should <br /> be made for each of the major work elements or phases. The total estimated labor cost is the sum <br /> of all the elements or phases multiplied by the approved project multiplier. The total estimated <br /> engineering cost is the total labor cost plus estimated reimbursable expenses. Alternately, <br /> replace this Exhibit with a spread sheet defining scope of work. Mark the spreadsheet Exhibit ' <br /> A.)
