As a leader in wind engineering for the past 40 years, Boundary Layer Wind Tunnel Laboratory has worked with engineers, architects and developers from all over the globe. Since its inception in 1965, the Laboratory has worked on over one thousand projects.

Their mission is to develop innovative solutions to complex wind engineering problems while maintaining the highest standards in research, education, and engineering applications.

They have developed many of, what are now, wind engineering's standard methods, such as the force balance measurement of loads on tall buildings. They have assisted in the design of some of the world's tallest buildings and structures, the world's longest bridges, and roofs of unusual construction and form.
