Imported boring rigs complete tough foundation job
Foundations of 1200 by 70 ft and 240 ft high grain elevator structure are supported on caissons placed by French Benoto machine; hydraulic, semirotary, boring rigs of Benoto system place and remove large diameter casings and can walk and turn on hydraulic jacks in confined spaces; 39 in. diam caissons were placed to support each column in structure, instead of previously planned 9 piles for each; 15% saving was achieved.
