ABSTRACT:
Column cutting method and apparatus wherein an abrasive saw is mounted pivotally on a track encircling a concrete column. Pivotal movement of the abrasive saw sequentially cuts a circumferential kerf around the periphery of the column including reinforcing members by pivoting the saw substantially radially into the column. An uncut center is left for support, which center is easily fractured for removal of superfluous column segment.
