Contract Costs

The total contract cost from January 22, 2002 to June 30, 2002 (the end of the school year) is estimated to be $184,203.93. A letter of explanation from the vendor and specific information pertaining to the ambient air sampling completed at IS 89 is I attached to this PW. The following information from the applicant and the applicant’s vendor was used to compute the total eligible cost;

The eligible costs incurred from January 22, 2002 to June 30, 2002 (160 days) = $184,203.93 (see attached sheet) 1 J Percentage of Work Completed

The percentage of work complete was calculated through May 6, 2002. As such, for 104 days of the 160 day period, the work performed by ATC Associates has been completed. The BoE has not been invoiced for these costs, and therefore the dollar amount in this PW is based on an estimate provided by the applicant’s vendor, ATC Associates.

104 days/ 160 day period = 65% of the work complete.
