Helix/R sculpture update: engineers flag NCDOT right-of-way, sewer and site constraints
Summary
A consultant told the Cramerton commissioners that geotechnical work and footing drawings for the Helix/R sculpture are complete but that the site requires additional engineering because it sits on fill dirt, crosses an NCDOT right-of-way and contains an old sanitary sewer and water lines; cost estimates will follow pending right-of-way clarification.
Gary Fankhauser presented an update on the Helix/R public-art installation during the Oct. 21 meeting of the Town of Cramerton Board of Commissioners.
Fankhauser said geotechnical testing and initial drawings to guide structural-footing design are complete and that a structural engineer has begun footing design. He noted several site constraints: the installation area contains fill dirt because it follows an old road bed; Cramer Mountain Road is a North Carolina Department of Transportation (NCDOT) roadway and the town needs to confirm right-of-way boundaries to avoid encroachment; an old sanitary sewer runs down the middle of the former road bed and there may be old water lines in the area. Those conditions will affect footing design and may require using pilings or lifting the footing to clear subsurface utilities.
Fankhauser said a large portion of the current asphalt trail will need replacement and accent lighting will be added. The surveyor has not located a deed for the right-of-way; Fankhauser will follow up with NCDOT and expects to return with cost estimates about 30 days after receiving the right-of-way information.
Mayor Pro Tempore Koutsoupias suggested contacting the crane company that installed an earlier Stuart W. Cramer art piece; the board asked staff to bring a cost estimate to the next meeting once NCDOT right-of-way information is available.
What’s next
Staff and consultants will confirm NCDOT right-of-way boundaries, resolve subsurface utility risks, and return with construction cost estimates and installation timing.
