A Charleston airport committee settled on an actual construction cost for redeveloping the terminal at Charleston International of $159 million today.

The cost includes about $12 million in contingencies and other allowances in case of changes by the airport when contractors begin tearing apart the 28-year-old terminal.

The price does not include extras for professional services such as program management, architecture, bond-related expenses and other services.

The original price of about $199 million will be less, but Airports Director Sue Stevens did not know the exact figure since numbers are still being tweaked.

The airport plans to issue about $176 million in bonds to pay for airport construction in August. The difference between the amount borrowed through bonds and the final total will be picked up by the Aviation Authority.

The expanded terminal will include six new gates, a third baggage carousel, consolidated security, new rental car pavilion, dome over the lobby and numerous cosmetic changes. The work should be completed in 2015.
