As part of the CH2M Hill team, Rii provided a geotechnical investigation, analysis and recommendations, as well as surveying and mapping services for the relocation of the Runway 10R/28L (South Runway).  The project included the runway and taxiway reconstruction, infield drainage areas, construction of a perimeter road, runway approach lighting and several major drainage structures.

Phase I, Aerial Photography
Rii acquired low-level aerial photography using a helicopter at an altitude of approximately 300 feet. Because of the location of some of the required photo control points, the existing south runway had to be closed for a short period of time. Through it all, close coordination with the Columbus CRAA was maintained.
 
Phase II, Surveying and Mapping
Before beginning the field work, Rii reviewed airport records to aid in the collection of data for the existing conditions. In addition, Rii worked closely with CH2M Hill in reviewing other mapping sources to make recommendations to the design team regarding the adequacy of existing mapping conditions for design use.

In the field, a topographic survey map was generated using the photogrammetric methods from the Aerial Photography obtained during Phase I. In addition, a field topographic survey was performed to locate existing features outside of the aerial mapping limits, including all storm water and miscellaneous structures, culverts and pipe inverts. All topographic surveys were incorporated into the Base Mapping and provided in AutoCAD format. Rii also performed vacuum excavation and field location on exposed utilities in approximately 75 locations.
