Over the past decade, Sully-Miller Contracting Co. has completed more than 40 projects at LAX, Burbank, John Wayne, Long Beach, and Ontario Airports.

Currently, Sully-Miller is working at LAX on the Taxiway D Extension Project, which will add 2,300 feet to the taxiway. The project includes the demolition of existing pavement, which will be reused as fill and base material. Subgrade preparation comes next with the laying of six inches of crushed miscellaneous base material, a recycled asphalt/concrete mix. Next, 12 inches of lean concrete base will be laid, then 19 inches of P-501 concrete is placed. The full scope of work includes PCC and AC pavement, airfield lighting electrical work, and airfield markings and signage. More than 20 miles of wire is being installed by subcontractor Aldridge Electric.

Sully-Miller is self-performing all of the 47,000 cubic yards of concrete pavement, plus 24,500 tons of hot mix asphalt. The concrete is being brought in daily by mixer trucks from Catalina Pacific, and the hot mix asphalt is provided by Blue Diamond Materials. Sully-Miller’s Gomaco GP3 slipform paver started the project, but was called to the I-15 Oak Hill Road Project. Stepping in as a replacement is the company’s Gomaco Commander III paver.

The project, valued at $84.5 million, started in February and is slated for completion in June 2024. The extension of Taxiway D to the west will enable more efficient management of the airfield operations, reducing wait times on the airfield. That translates to less idling of aircraft and a resulting decrease in carbon dioxide and other exhaust emissions. In addition, flight delays will be reduced and a safer taxiway environment created.
