Coring and benching of this material is performed by the contractor in the field. In order to determine the amount of barrels and collars required for the manhole structure to meet grade, please refer to the Southern Alberta catalogue for an estimate guide, or alternatively, provide your local Lafarge representative with a rim and invert elevation. stormwater treatment technologies box sections 630 205 155 105 75 50 150 170 190 - manhole and catch basin material - LAFARGE PIPE eMANUAL PAGE 23
