Sterling Awarded $80 Million Aviation Project in the Marshall Islands

Sterling Construction Company, Inc. (NasdaqGS: STRL) (“Sterling” or “the Company”) today announced that its subsidiary, Road and Highway Builders, LLC (“RHB”), has been awarded an $80 million aviation subcontract by Parsons Corporation (“Parsons”) for the reconstruction of the Bucholz Army Airfield Runway in the Kwajalein Atoll of the Marshall Islands. Our efforts are a part of Parsons project with the US Army Corps of Engineers (USACE).

The project consists of paving a 200 foot by 6,000 foot runway in order to accommodate increased air traffic. Innovative phasing will allow the runway to remain operational while construction occurs, as the strategic significance of the airfield does not allow reconstruction to close the runway. Logistics has commenced to transport aggregates, other materials and equipment to the airfield. The reconstruction project has an estimated completion date of mid-2021.

“We are honored to have been selected to efficiently and safely improve the Bucholz Army Airfield, a critical strategic post for the U.S. military’s Pacific presence,” stated Joe Cutillo, Sterling’s CEO. “RHB has expertise in this type of terrain and remote working environment that can be brought to bear on this reconstruction. This project is yet another example of Sterling continuing to successfully execute our strategy of diversification away from the low-bid heavy highway business and illustrates the strength of our end markets, especially in these highly uncertain times.”
