The infrastructure company that was awarded a contract to design the first building at the Stockton Aviation Research and Technology Park already wants to be paid more. Infrastructure company AECOM was last month granted an additional $41,234.00 for an amended contract worth $738,390.00, according to the minutes of the Atlantic County Improvement Authority’s August meeting. The extra money is needed because when AECOM submitted its original bid, the scope of the project was not yet finalized, according to the minutes. “Therefore, certain assumptions were made, and while some of these assumptions were correct, some were inaccurate,” the minutes state. Among the changes are an allowance to design a “Thunder Room” (a kind of top-notch conference room, apparently) and a roof-top deck.
