In August of 2020, Sam O Hirota, Inc. conducted a Topographic Survey of a portion of the project area being the grounds around the “Hawaii State Art Museum”, and fronting roads Hotel Street and Richard Street.  The field survey located elevations, improvements, trees with diameter of 0.5-feet and greater, top and bottom of walls and slopes, measured utility inverts and pipe sizes, and determined ground topography.  The project was surveyed at 1-inch=20-feet scale.  A plan delineating located features and improvements, and contours at 1-foot intervals, as related to subject boundaries, was produced and provided.  Deliverables consisted of Civil3D “DWG” file and PDF files of the topographic survey.

In addition to a detailed topographic survey, SOH utilized its company-owned Navvis mobile mapping system to laser scan and capture full-color spherical images of the exterior and selected interior elements of the building and surrounding grounds.
