Evaluation of image-based modeling and laser scanning accuracy for emerging automated performance monitoring techniques
TL;DR: An overview of the newly developed automated image-based reconstruction approach and exclusive features which distinct it from other image- based or conventional photogrammetric techniques is presented and the terrestrial laser scanning approach carried out for reconstruction and comparison of as-built scenes is presented.
Journal ArticleDOI
Automated Progress Monitoring Using Unordered Daily Construction Photographs and IFC-Based Building Information Models
TL;DR: In this article, a new automated approach for recognition of physical progress based on two emerging sources of information: (1) unordered daily construction photo collections, which are currently collected at almost no cost on all construction sites; and (2) building information models (BIMs), which are increasingly turning into binding components of architecture/engineering/construction contracts.
Journal ArticleDOI
Automated construction progress measurement using a 4D building information model and 3D data
TL;DR: In this paper, the authors developed an accurate, essentially fully automated method for construction progress measurement using a 4D BIM in concert with 3D data obtained by remote-sensing technology.

Data acquisition technologies for construction progress tracking
Tarek Omar,Moncef L. Nehdi +1 more
TL;DR: In this paper, the authors examine different technologies of automated and electronic construction data collection and compare them to identify various trends concerning their applicability in real-time data acquisition of construction projects and make recommendations for their suitability in different projects.

Automated Object Identification Using Optical Video Cameras on Construction Sites
Seokho Chi,Carlos H. Caldas +1 more
TL;DR: In this paper, the background subtraction algorithm extracts motion pixels from an image sequence, the pixels are then grouped into regions to represent moving objects, and finally the regions are identified as a certain object using classifiers.

Causes of Quality Deviations in Design and Construction
TL;DR: In this paper, the authors collected quality deviation data from nine fast-track industrial construction projects and identified the direct costs associated with rework (including redesign, repair, and replacement).
Journal ArticleDOI
The causes and costs of defects in construction. A study of seven building projects
TL;DR: The purpose of the study presented here is to stimulate improvements by indicating where preventive measures are most effective as well as how to perform them.

Supply strategy and network effects — purchasing behaviour in the construction industry
Anna Dubois,Lars-Erik Gadde +1 more
TL;DR: In this article, the authors explored the occurrence of network effects in the construction industry and concluded that these characteristics are having a hampering effect on both efficiency and innovation in the industry today.
Journal ArticleDOI
The application of active radio frequency identification technology for tool tracking on construction job sites
TL;DR: In this paper, the authors developed a tool tracking and inventory system which is also capable of storing operation and maintenance (O&M) data using commercially available active radio frequency identification (RFID) tags.
