Abstract: A block positioning tool includes a first elongated member and a second elongated member attached together such that a L-shaped frame is formed. The frame has an upper surface and a bottom surface. The first and second elongated members each have a slot therein extending through the upper and bottom surfaces. Each of the first and second elongated members has an associated attached end and a free end. A plurality of position indicators is attached to and selectively moveable along a length of the slots. A primary anchor is attached to a bottom surface of the attached end. Each of a plurality of secondary anchors is attached to one of the position indicators and positioned adjacent to the bottom surface. Each of the secondary anchors and the primary anchor is removably positionable into depressions extending into an upper surface of pier blocks.
