Transportation and Construction Inspection & Testing
The Tri-Cities Airport is a public airport approximately 2 miles northwest of Pasco, Washington. It is the third largest commercial airport in the state of Washington, and has three runways. The Tri-Cities Airport (operating as the Pasco Airport) was the site of the first airmail contract flight between Elko, Nevada, and Pasco, Washington made by Varney Airlines, (later United Airlines) in 1926. During World War II this airport was an integral part of our nations defense training for the US Navy. After the war, the US Navy sold the field to the city of Pasco. Throughout the years the airport buildings have also housed educational facilities. In 1955 the old administration building was home of Columbia Basin College until 1966. The building was later leased to the Pasco School District #1, for use as Pasco Alternative High School until it was destroyed by fire in the mid-1980s.
In 2003 the airport underwent another expansion and remodel that added an additional 3,000 square feet to the ticket lobby and boarding area. In 2014 the airport was approved for a $42 million expansion and renovation. STRATA has performed numerous geotechnical engineering and construction material testing projects at the Tri-Cities Airport over the past several years. Currently we are performing Quality Assurance Testing Services for Taxiway A Realignment and Rehabilitation. The project consists of realignment and construction of approximately 4,200 linear feet of the eastern portion of Taxiway A, and rehabilitation of 4,200 linear feet of Taxiways A, B and C. Work includes removal of asphalt concrete pavement and cement treated base, pavement milling and profiling, excavation, subgrade preparation, grading, and placement of under-drain piping, drywells, catch basins and crushed aggregate base course, cement treated base, bituminous surfacing, electrical lighting modifications, lighted guidance signing, and striping. Work has taken place in four phases beginning in 2018 and should be completed in 2019.
