Bilby tower

[2] In 1927, Herbert Hoover, then the Secretary of Commerce, commended Bilby's tower "for its cost and time efficiency" and cited the surveyor's service as "essential to the United States government".

[5] The tower was tested with positive results and Bilby received a commendation from Secretary of Commerce Herbert Hoover for the invention.

[6] The Bilby Tower was a massive success, saving money compared to previous options and increasing the efficiency of the USC&GS surveyors.

[7] In 1928 alone, use of the Bilby Tower cut costs by up to 35%, and over its first ten years of use it saved the government an estimated $3,000,000 (equivalent to $52,620,690 in 2023).

[14] Its quick erection made it possible to conduct surveying rapidly—a team of five men could assemble a steel Bilby tower in only five hours.
