The Madison Airport Board voted Tuesday to spend an additional $18,000 to complete an airport layout plan (ALP) for all of the expansions it would like to see.
According to board chair Wilma Walker, the body originally spent $22,000 on the plan, which included an extension of the runway apron. However, at a previous meeting the board voted to broaden the plan to include a geotechnical survey of potential sites for additional hangars and a new terminal building.
Susan Rich, a representative of Stantec, the airport’s engineering firm, said costs increased because of topographical features that must be taken into consideration by the new survey. Characteristics such as building height, which previously were not relevant when the issue was just apron expansion, must be included in the survey if new buildings are envisioned.
With the additional cost, the total ALP price will be about $40,000, Walker said.
In other business, the board:
• Received an independent fee review from another engineering firm with proposed costs and hours necessary for the proposed apron expansion. According to Walker, the price given by the reviewing company, while not stated, was about 10 percent lower than the estimate from Stantec. Before the Federal Aviation Administration will fund a project, its requires airports to negotiate with its contacted engineer if a comparable firm states it could do the work for at least 10 percent less, Walker said.
• Airport Manager Jason Bonham said that on five occasions in the last two months runway lights have gone out. He is searching for the cause and will report to the board when it is determined.
