Page 2 of 8 <br />III. Engineer's Estimate <br />a. Basis of Estimate <br />The Engineer's Estimate for the time related costs totaling $140,936.36 was based the original <br />contract amounts for the MOT ($285,600.00) and Erosion Control ($28,000.00) pay items divided by <br />the number of original contract days (720 calendar days) to determine daily rates of $396.67 and <br />$38.89, respectively. For the Indirect costs, Expenses and Profit, the industry standard 8% formula <br />($13,641,589.27 x 0.08/ 720 cal. days) was used to develop a daily rate of $1,515.73, which was <br />applied to the days of delay, less the industry standard 10 days allowed by FDOT Specification 4-3.2 <br />as well as the 9 days during which the Contractor performed the extra work. Compensation for the <br />indirect costs on the days of the extra work are included in the markup on the extra work. <br />b.
