Lo, Y; Zhang, C; Ye, Z and Cui, C (2023) Monitoring road base course construction progress by photogrammetry-based 3D reconstruction. International Journal of Construction Management, 23(12), pp. 2087-2101. ISSN 1562-3599
Abstract
Infrastructure industry is a significant contributor to a country's economy, but it is beset by cost overruns and delays. Therefore, project monitoring is essential to determine project performance by comparing the site progress to the schedule baseline. However, manual tracking lacks the precision and efficiency. The ability to quickly and accurately identify differences is important to implement essential measures to reduce the impact of delays. This paper aims to build a technology-assisted progress monitoring framework for road base course construction. A case study is carried out on a road construction site using an Unmanned Aerial Vehicle to capture as-built data in a timely manner. Photogrammetry is used to generate point cloud model as the 3 D geometrical representative of the site. Percentage of Completion is computed as an indication for the progress of the construction along with the location of the work performed and the quantity of the material used. The framework produced a detailed and accurate construction progress report with evidence support from point cloud data which allows the visualization of the actual construction site in three dimensions. The findings reveal that the framework enables accurate and efficient tracking of road base course construction progress as well as schedule comparison.

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
