Mount Olive Very High Frequency Omni-Directional Range (VUZ VOR) Stair Refurbishment

Performance Specification for Refurbishment of Existing Pressure -Treated Wood Staircase at VUZ VOR.

1) Introduction / Project Overview This document outlines the performance specifications for the refurbishment of an existing pressure-treated wood staircase located in a highly vegetative exterior application. This stairway connect the FAA VUZ VOR equipment shelter with the adjacent hilltop antenna array. The stairs span an elevation change of approximately 50 feet / 4 stories with 3 intermittent landings across the span. The project goal is to rebuild this staircase and restore the structural integrity and functionality of the stairs while optimizing safety and aesthetics. The existing stair assembly does not have any balusters or risers and is built with 2 outboard stringers supported intermittently with existing in ground footings that have been found to be intact and capable of reuse.
