In this era of computer-aided design, the skills required to create a single-sheet measured drawing of a building may seem to be irrelevant. Yet as a means of fully understanding and documenting a design, architectural delination is invaluable. Now, the National Park Service is administering an annual prize for the best drawing: "The Leicester B. Holland Prize is an annual competition that recognizes the best single-sheet measured drawing of an historic building, site, or structure prepared by an individual(s) to the standards of the Historic American Buildings Survey (HABS), Historic American Engineering Record (HAER), or the Historic American Landscapes Survey (HALS). The prize is supported by the Paul Rudolph Trust, Architectural Record, and the Center for Architecture, Design & Engineering in the Library of Congress, and administered by the Heritage Documentation Programs of the National Park Service (HABS/HAER/HALS/CRGIS)." Pictured above and below are the winning entries for 2012. Information about the annual competition can be found here.
