Jaselskis, E J; Gao, Z and Walters, R C (2005) Improving transportation projects using laser scanning. Journal of Construction Engineering and Management, 131(3), pp. 377-384. ISSN 0733-9364
Abstract
This paper describes a case study investigating the use of laser scanning to acquire design and construction data. It is intended for both industry practitioners and academics who are interested in this relatively new technology. Included is a brief description of the technology, discussion of the case study, lessons learned, and results. Projects in the case study included an intersection, highway, pair of bridges, new pavement, bridge beams, a stockpile, and a borrow pit so that different perspectives (elevation, smoothness, camber, and volume) of the application were tested. The study proved that laser scanning is ideally suited for measuring the volume of soil and rock, determining road surface elevations and bridge beam camber, and assisting in the creation of as-built drawings in a three-dimensional environment. It was discovered that this technique can be used quite effectively for safer and more accurate construction measurement. Time requirements, cost comparisons to photogrammetry, and limitations are also discussed.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
