Hardlines Design Company completed the Wright-Patterson Air Force Base HABS Documentation for more than 40 buildings at the base, ranging in date from the 1930s through the late 1940s. Most of the work was performed to Ohio state mitigation standards, although some of the documentation was approved by the National Park Service, including the National Civil Engineering Landmark 5-foot wind tunnel, which was built by the Wright Brothers.
The HAER documentation of buildings included Levels I, II, and III, and included measured drawings, large-format photography, and extensive research.
