The city of Sedona’s new consulting report on the structural integrity of the Georgia Frontiere Performing Arts Pavilion at the Sedona Cultural Park has concluded that most of the structure remains in good condition and is suit able for restoration.

The inspection was conducted by Core Structure Group of Flagstaff on Feb. 19, and the report was provided to the city in March. Core Structure’s services were limited to conducting a visual inspection only without employing excavation or invasive methodologies.

“Due to the deterioration of the glulam beams, they will require structural remediation to restore the structural capacity lost to weathering,” the report stated regarding the pavilion’s arches, adding that weathering had affected the top two layers of lamination on some of the beams.

Glulam is “glue-laminated timber,” an engineered wood product consisting of several parallel layers of small pieces of lumber stacked and glued together under pressure to make a large timber structure.

“The deterioration noted does not appear to be extensive enough to require full replacement of the members, nor does it render them useless for repurposing for a new structure,” the report stated.

The consultants also noted three missing bolts on the structure and a partial deterioration of the spray foam waterproofing used on the roof, which had resulted in patches of rot within the decking.

“The bolted splices at mid-span appear to be in good condition. In addition, the bolted hinged connections at the arch apex appear to be in good condition,” the report stated. “The wood subfloor of the stage requires complete removal and replacement. It is not possible to remediate the existing deteriorated plywood. The steel appears to be in good condition. No significant rust was observed in the canopy steel framing, the connection plates or in the bolts. Foundations and concrete structures appear to be in good condition. Substantial cracking or deterioration were not observed. There were no signs of significant foundation movement or failure.”

“Based on our visual investigation, it is our professional opinion that the amphitheater structure is not in danger of imminent collapse,” the report concluded, with the consultants recommending annual inspections in the future if remediation does not take place within the next year.

The pavilion’s architects, Dan Jensvold and Steve Thompson, and its builders, Western Wood Structures, notified the city in March 2023 that the structure retained potentially decades of useful life and also identified the stage floor and roofing as being in need of replacement.
