Over the last decades, numerous Automated Compliance Checking (ACC) systems have been developed. However, ACC is still not broadly used in the real world today; little is known as to how ACC can be better accepted by the end users. This paper reports on a multiple-case study to learn valuable lessons from recent attempts to adopt Automated Complian...

The bridge models reconstructed from unmanned aerial vehicle (UAV) images via photogrammetry are often reported to have quality issues (e.g., high noise, insufficient resolution and precision loss) and thus restrict their application in bridge inspection. To address this problem, this paper proposes a novel Building Information Model (BIM)-based 3D...

As-built progress of the constructed pavement should be monitored effectively to provide prompt project control. However, current pavement construction progress monitoring practices (e.g., data collection, processing, and analysis) are typically manual, time-consuming, tedious, and error-prone. To address this, this study proposes sensors mounted u...

Unmanned Aerial Vehicles (UAVs) and photogrammetry have been widely used to reconstruct a photo-realistic 3D model of physical bridges for documentation of cultural bridges or remote bridge inspection. However, the optimal image overlap for photogrammetric bridge reconstruction that can trade off the model quality and overall mission time has not y...

During construction, pavement projects often suffer from a lack of progress certainty, which leads to cost and time overruns.

This study reports a case study that investigates the gap between BIM tertiary education and the building industry's needs in New Zealand (NZ). In specific, it aims to (1) identify the industry's requirements on BIM competencies, (2) examine the status quo of BIM tertiary education in NZ, and (3) identify and analyse the gaps between current BIM ed...

Reinforced concrete (RC) structures are prone to spalling damage. Successful detection and quantification of spalling are critical to monitoring the structural safety condition. Point cloud generated by emerging surveying technologies such as photogrammetry, laser scanning and Light Detection and Ranging (LiDAR) has been growingly used for spalling...

As Building Information Modeling (BIM) workflows are becoming very relevant for the different stages of the project’s lifecycle, more data is produced and managed across it. The information and data accumulated in BIM-based projects present an opportunity for analysis and extraction of project knowledge from the inception to the operation phase. In...

In the aftermath of severe earthquakes, building occupants evacuation behaviour is a vital indicator of the performance of an indoor building design. However, earthquake evacuation has been systematically neglected in the current building design practice. Arguably, one of the primary reasons for this is that post-earthquake evacuation behaviour is...

Purpose Many applications of Building Information modelling (BIM) are already integrated into project management processes. However, the construction industry is suffering from poor decision-making, especially during procurement where fundamental decisions are made. To make the best decisions at earlier project stages, such as design, large amount...

Purpose This article aims to explore valuable insights into the construction progress monitoring (CPM) research domain, which include main research topics, knowledge gaps and future research themes. For a long time, CPM has been significantly researched with increasing enthusiasm. Although a few review studies have been carried out, there is non-ex...

With the recent advances in Information and Communication Technologies in the construction industry, information is exchanged digitally with little regard to the contracts that govern them. Although parties collaborating in project design are contracted to the client, they transact with each other when using BIM and other collaborative practices wi...

Completing safety evaluations of buildings is critical for the health and safety of a city’s community following a damaging earthquake. Most contemporary post-earthquake evaluations involve groups of people who physically inspect buildings, most often without training specific to evaluating earthquake damage. Three main problems arise from this pra...
