Miami International Airport Northside Runway - Miami, Fla.
Air traffic at Miami International Airport was steadily increasing, both in air freight and in passengers. As a result, the airport authority decided that a new runway was needed. In late 2000, Gilbert Southern Corp., a subsidiary of Kiewit Corporation, was awarded the North Runway project to increase the airport's capacity by 25 percent. This $115 million project included constructing an 8,600-foot-long runway, two taxiways, drainage, demolition, utilities, electrical and communications work, and concrete and asphalt paving.
Completed in August 2003, the project was built in 66 different phases and routed through a series of existing warehouse taxiways to maintain access to active businesses. Quantities included 83,000 square yards of concrete; 250,000 tons of asphalt; and more than 35,000 feet of 18- to 66-inch-diameter drainage pipe. The electrical and communications system included more than 40 miles of duct banks and more than 3,600 taxiway lights.
Most of the existing pavement had to be removed. The asphalt paving was milled and transported off-site for recycling, while the concrete pavement was crushed and recycled on-site for construction aggregate. The removed concrete drainage structures and pipe were crushed as well.
