Bayrak, T and Kaka, A (2004) Evaluation of digital photogrammetry and 3D CAD modelling applications in construction management. In: Khosrowshahi, F (ed.) Proceedings of 20th Annual ARCOM Conference, 1-3 September 2004, Edinburgh, UK.
Abstract
The objective of the paper is to report ongoing research work aimed at developing computer based model that will enable the semi-automatic measurement of construction work in progress. CAD programs are increasingly being used to produce more realistic 3D models of the designed buildings, long before the start of construction on site. These 3D models are usually applied for presentation and visualisation purposes. However, there is greater potential for making use of these 3D CAD models for the development of an automated data capture system. A great deal of time is spent to collect information from the site using conventional measurement techniques. These measurements help project managers to calculate interim payments, monitor progress, analyse productivity and undertake Earned Value Analyses. Recent developments in digital photography and computerised photogrammetry techniques will make it possible to acquire, record and process construction information more rapidly. This paper discusses the potential application of such system and presents a conceptual framework for semi-automated progress measurement system. The paper then outlines the development of the methodology to be used for the automatic comparison of the "data acquired from site" and "data from the existing design documents".

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
