Dioptra was contracted by Cannon Builders to perform all construction surveying for the replacement of a bridge over Mink Creek just north of Mink Creek, ID. This project consisted of resetting NGS Benchmark Q341. Q341 was originally set on the bridge deck and as such would be destroyed during construction. Using our training provided by retired NGS employee Curt Smith, we referenced the elevation of the original benchmark. Once the new mark was placed, we completed a 4-hour OPUS observation on the mark and transferred elevation back to the new mark. This method established NGS Benchmark Q341 RESET as a 3rd-Order NGS monument.
