What is the largest clearspan building?
The largest clearspan building in the world is the Boeing Everett Factory in Everett, Washington, USA. This massive structure is 97 meters (318 feet) tall. Covers an area of 398,000 square meters (98.3 acres), and has a clearspan of 93 meters (305 feet). It is the largest building in the world by volume and the largest manufacturing facility in the world.
The Boeing Everett Factory, built in 1966 to manufacture the Boeing 747. Moreover, the first wide-body commercial airliner. Since then, expanded several times to accommodate the production of other aircraft, including the 767, 777, and 787 Dreamliner. The factory employs more than 30,000 people and produces up to 20 airplanes per month.

The clearspan of the Boeing Everett Factory achieved through the use of a unique construction technique! Moreover, called the “triple-deck truss.” The building becomes supported by two massive parallel trusses, each consisting of three levels, or “decks.” The trusses, spaced 30 meters (100 feet) apart. And span the entire length of the building. The trusses, supported by columns spaced at 27 meters (90 feet) intervals.
The use of the triple-deck truss system allows for an unobstructed interior space. One that is free from support columns or walls. Thus, makes the building ideal for the production of large aircraft. Which require a great deal of open space for assembly and movement.
What is the largest clearspan building?
The Boeing Everett Factory is a remarkable feat of engineering and construction. And its clearspan of 93 meters is truly impressive. However, worth noting other buildings with even larger clearspans not considered “buildings” in the traditional sense.
For example, the Millau Viaduct in France has a clearspan of 342 meters (1,122 feet) and is technically a bridge. Similarly, the Astrodome in Houston, Texas, USA. Boasted a clearspan of 185 meters (610 feet) when built in 1965. Thus, making it the largest clearspan building at the time. However, since surpassed by the Boeing Everett Factory and other structures.
In conclusion, the Boeing Everett Factory is the largest clearspan building in the world, with a clearspan of 93 meters. Its unique triple-deck truss system allows for an unobstructed interior space that is ideal for the production of large aircraft. While there are other structures with larger clearspans, the Boeing Everett Factory remains an impressive feat of engineering and construction.
