The Hubbell Trading Post is the oldest operating trading post on the Navajo Nation. Purchased in 1878 by the Hubbell family, the trading post became a National Historic Site in 1967 and is still in operation today.

DJ&A was responsible for surveying the interior and exterior of nine existing historical buildings within the Hubbell Trading Post National Historic Site.  Surveying at this historical site required special attention by our survey crews to avoid impacting elements that contribute to the historic fabric of the site. A combination of both LiDAR-based and conventional surveying was used to accomplish this task.  Using the measurements collected, DJ&A provided measured, detailed drawings showing the existing as-built conditions of the buildings on the site.  DJ&A also provided a detailed site plan and floor plans, exterior elevations, interior elevations and ceiling plans for each building.

Key Services

• Performed Light Detection And Ranging (LiDAR) survey to produce drawings showing existing “as built” conditions for nine existing buildings at Hubbell Trading Post National Historic Site
• Using the LiDAR measurements, DJ&A provided measured, detailed drawings showing the existing as-built conditions of the nine buildings
• Drawings were prepared in AutoCAD format and conformed to NPS CAD & drafting standards

Value Added

Using spherical photos obtained from the laser scanner, DJ&A provided the NPS with the ability to conduct virtual tours for each of the main buildings so NPS staff and visitors to the historic site could visually “walk” through each space without causing further deterioration to the buildings.
