Brockington historians are experienced with the Historic American Building Survey (HABS), Historic American Engineering Record (HAER), and Historic American Landscapes Survey (HALS) programs administered through the National Park Service (NPS). While we sometimes work directly through the NPS, often documentation packages serve as mitigation for an adverse effect proposed by a specific undertaking and carried out under a specific agreement reviewed and approved by the SHPO.

Documentation is often required in circumstances when NRHP eligible (or listed) buildings or structures cannot be preserved and will be impacted by development. Recordation and documentation are seen as providing Architectural Mitigation of the proposed adverse effects. Such mitigation programs would be undertaken under a specific plan (Memorandum of Agreement [MOA]) reviewed and approved by the permitting agency.

Recordation typically involves preparation of historic information, photographic documentation, and measured drawings based on NPS guidelines (Level I, II, III, or IV) and negotiated with the SHPO. Sometimes the level of documentation required is less than NPS standards and we are capable of working with agencies and SHPOs to determine the appropriate recordation technique.

Documentation that is typically done includes the creation of building plans and maps as well as photography with a 4x5 large format camera. All photography is archivally processed and printed on archival paper.

To supplement photography, we can use laser scanning to produce accurate models of buildings and structures.

Extensive historical research is also done for each significant property and district. All historical photographs, research and plans are incorporated in to the final package, and all materials are organized and submitted to the National Park Service in accordance to HABS/HAER/HALS guidelines.

We have extensive experience at all levels of documentation, and conduct all work in-house, except when a licensed architect is necessary. Furthermore, we have access to technical staff that can use laser scanning to produce accurate models of buildings and structures and we have submitted large format photographic documentations to the National Park Service.
