Abstract
A tool system is provided for aligning and plumbing a poured concrete form (e.g., a lower vertical form portion) for forming a structural column assembly of the type used for erecting building structures and the like, such as a concrete column or footing formed in situ in an earthen hole. The system includes a center line running vertical to the length of the tool and a two-way level system incorporated therein. The tool can be used to line up the lower vertical form portion with a layout string and plumb the lower vertical form portion square. A metering pole that can be locked in place is used to lower and raise the tool into and out of the lower vertical form portion, wherein the tool is completely rotatable about the metering pole. Once the lower vertical form portion is aligned with the tool, the earthen hole is back filled, thus holding the lower vertical form portion in place in the correct position. A hot knife system can be used in conjunction with the metering pole of the tool to cut the top of the lower vertical form portion to grade.
