Abstract

As a follow-up to ICT Project R27-030, Evaluation of 3-D Laser Scanning, this report provides findings of an evaluation of 3-D laser scanning equipment to determine the tangible costs versus benefits and the manpower savings realized by using the equipment in place of or in conjunction with conventional surveying methods. The Trimble TX5 laser scanning unit was used for this study. Two projects in District 8 were used for comparing manpower requirements for conventional surveying methods with those for 3-D laser scanning. Other projects were included in this evaluation under the objective of expanded use of the laser scanning equipment and included surface topography mapping of bridge decks, bridge beam deflection scans, and detailed surface mapping of various structures. Overall, the evaluation of the 3-D laser scanning equipment as a new technology for IDOT has been successful in documenting the benefits and shortcoming of its use on IDOT projects. It is the opinion of the participants that implementation of this technology in the various phases of IDOT projects is warranted and will benefit the department. Direct benefits of use of 3-D laser scanning technology included reduction in total project time; better accuracy of data; reduction in personnel hours spent in the field, which results in improved worker safety and less disruption to the traveling public; and innovative and alternate uses of the equipment.
