Up to 95 percent of the $3.7 million north apron rehabilitation and expansion at Cobb County International Airport-McCollum Field will be paid by the Georgia Department of Transportation.

The Cobb County Board of Commissioners approved the contract 5-0 Monday with Astra Group Inc. Also, the commissioners approved $188,010 for Michael Baker International Inc., formerly The LPA Group, to provide construction administration services for this project.

The four-month project is expected to start in late June or early July, according to Airport Manager Karl Von Hagel. The first phase will involve the construction of a new taxilane connector between Taxiway A and the north apron west of A2.

Then work will begin on rehabilitating and expanding the north apron between the restaurant and eastward to the control tower. The rehabilitation of the apron west of the restaurant is not funded in this project and will be addressed in a future project, Von Hagel said. The old rotating beacon also will be removed by the contractor during this project. Information: CobbCountyAirport.org, Karl.VonHagel@CobbCounty.org.
