Dowel bars - Scanning on one side of a joint, perpendicular to the dowel bars

Length of dowel bars 18”

Bottom view is the Focus Mode view. Note the dowel bar and the cage.

By scanning on each side of the joint or saw cut, surveyors can map the position of each dowel bar and determine whether it is positioned correctly or skewed. Depth of the dowel bar may also be determined.

Determine Tie Bar Location for QA/QCBy scanning perpendicular to a joint, determine the location of tie bars.

Tie bar location

Processed 3D data of dowel barsBy scanning parallel and directly over one dowel bar, one may determine the length of the dowel bar and the location of the dowel bar in relation to the joint.
