Project Title:
  Evaluation of 3-D Laser Scanning for Construction Applications
Start Date: 10/1/2007
End Date: 9/30/2009
Summary of Project:
  The use of laser scanning equipment to produce three-dimensional representations of objects and surfaces is a new technology that has significant potential for monitoring highway and bridge construction activities. Examples of potential uses of laser scanning include obtaining accurate pre- and post-construction terrain models for determination of earthwork quantities, especially in urban areas or on reconstruction projects; monitoring pavement smoothness and adherence to design grade; and monitoring ground movement near excavations, large embankments, or pile-driving operations. However, to prove the accuracy of this new method, data obtained using laser scanning technology need to be compared to data obtained using traditional methods. ICT is conducting this research to validate the feasibility of using laser technology to monitor IDOT highway construction activities and transportation structures. A cost-effective and accurate laser technology has significant potential to impact the efficiency and cost control of future construction projects.
Objective of Project:
  The objective of this project is to determine cost-effective means to implement laser scanning technology in the constuction phase of IDOT projects. The primary goal is to study use of laser scanner for evaluating pay quantities for earthwork operations. Software will be developed to aid in planning of laser scanning operations, and to determine earthwork quantities. The use of laser scanning for monitoring settlement during pile driving operations will also be studied. Other applications in road construction will be evaluated in consultation with the TRP.
Expected Outcome:
  Validation of the feasibility of using laser technology to monitor IDOT highway construction activities and transportation structures. A cost-effective and accurate laser technology has significant potential to impact the efficiency and cost control of future construction projects.
