The engineering company responsible for the design of the new Stockton Aviation Research and Technology Park has requested more money for the job, raising the total contract cost by 9 percent. The additional costs are connected with work that was not included in the original scope of the project, according to a letter sent by AECOM, the international engineering company carrying out the work, to the Atlantic County Improvement Authority (ACIA). The ACIA approved the request last month. The new work, worth $28,031, takes the total cost of the job up to $766,421.00. A previous change order, approved by the ACIA in August, gave AECOM an additional $41,234.00.
