Abstract

The objective of the project was to evaluate cost-effective means to implement laser scanning technology in the construction phase of IDOT projects. The primary goal was to study the use of a laser scanner for evaluating pay quantities for earthwork operations. The feasibility of using a scanner for other applications such as monitoring settlement due to pile driving, providing initial survey data for design, evaluating gravel and pavement thickness, assessing pavement roughness, surveying damaged bridges, and documenting archaeological investigations was also evaluated. Laser scans of ongoing construction projects were performed, and the workflow for operation of the scanner in the field was developed and documented. Software was developed using Visual Basic 2005 to process the data and to compare scanner data to a conventional survey. The research showed that laser scanning technology is a feasible means to measure earthwork quantities for payment in highway construction projects. Used in conjunction with traditional surveying techniques and equipment to establish horizontal and vertical control, the laser scanner can quickly map the terrain and provide data for earthwork quantity calculations.
