ARG performs Historic American Building Survey/Historic American Engineering Record/Historic American Landscapes (HABS/HAER/HALS) documentation for projects ranging from individual structures to 50-building historic districts. These projects are completed using the firm’s staff of historical architects, architectural historians, and preservation planners who all meet The Secretary of the Interior's Historic Preservation Professional Qualification Standards.
