The best place to search for that information would be in Record Group 77 (Records of the Office of the Chief Engineers 1789-1999 found here: https://catalog.archives.gov/id/406 . A precursory search of the National Archives Catalog ( http://https://www.archives.gov/research/catalog) for "Wendover Air Base" produced a number of results, including Construction reports for Wendover Air Base / Bombing Range (https://catalog.archives.gov/id/6792077 ).
For more information about these records, you can contact the Textual Reference Branch at the National Archives at College Park here : Archives2reference@nara.gov. Please note, they have not been digitized.

According to wikipedia: Construction of the base began on 20 September 1940 and on the range on 4 November 1940. Wendover Air Base became a subpost of Fort Douglas in Salt Lake City on 29 July 1941. By that time a total of 1,822,000 acres (737,000 ha) had been acquired for the base and associated gunnery/bombing range 86 miles (138 km) long and 18 to 36 miles (29 to 58 km) wide. During World War II, it was a training base for B-17 and B-24 bomber crews. After the war, Wendover was used for training exercises, gunnery range and as a research facility. It was closed by the Air Force in 1969, and the base was given to Wendover City in 1977. Tooele County, Utah, assumed ownership of the airport and base buildings in 1998, and the County continues to operate the airfield as a public airport.
