Bridge Construction Monitoring using LIDAR for Quantified, Objective Quality-Control Quality-Assurance (QOQCQA)

The New Mexico Department of Transportation (NMDOT) is interested in exploring new technology available and implementing it in the quality-control quality-assurance (QCQA) of bridge construction, in particular during concrete pour and concrete finishing. To date there are no 3D requirements in the form of QCQA standards for the constructed concrete structures (in particular bridge decks). According to NMDOT, the current QCQA requirements are limited to the measurement of discrete points. If the entire volume/surface could be compared with the designed profile (in 3D) then the quality of the finished surface would be quantified and assessed with more precision. This study will develop and implement a methodology to measure construction progress and compare it with the projected 3D shape, quantifying the difference. This project will propose its implementation for the development of DOT standards that can be added in upcoming future bridge construction documents.
