A robotics-assisted foundation installation system is provided in which data reporting the X, Y, and Z positions of foundation column tops are sent from a total surveying station to a grid control system. The grid control system receives the data and associates specific data with specific columns in an array—the “grid.” The grid control system compares the actual positions of the columns in the grid to target positions that were determined based on the requirements of the structure to be supported. After determining differences between the actual positions and the target positions, the grid control system sends instructions to column positioning tools associated with the individual columns. Actuators in a column positioning tool are directed by the grid control system to adjust the position of the associated column. Once the live streamed data confirms that each column is in the proper position, the columns are fixed in place.
