“…The methods used to record the building were simple and low-cost, being performed by non-expert operators. Surveys conducted by experts, on the other hand, would utilise modern technologies such as photogrammetry and laser scanning (Rashidi et al , 2017; Hassani, 2015). Our surveyors were non-expert third-year students conducting a survey for the first time as part of their module exercises.…”

“…Our surveyors were non-expert third-year students conducting a survey for the first time as part of their module exercises. Hand surveys were performed using simple tapes and laser distance measurers (Rashidi et al , 2017; Hassani, 2015; MacDonald, 2006). Students, through their surveying exercise, conducted multiple measuring activities for the same object with similar as well as different tools.…”

Purpose The purpose of this paper is to detail an actor-network theory inspired ethnography of recording heritage buildings. The case study focusses on Irbid School in Al Tal area, which is one of the oldest schools in Jordan and an important heritage building. Design/methodology/approach The recording process was undertaken by third-year architectural design studio students from Philadelphia University. The paper documents the interaction between the heritage building and the students in a two-phased ethnography, including fieldwork conducted between September and December 2017. Findings The paper proposes the concept of “transfer ethnography”, which considers the continuous changes in design across different locations. This extends beyond traditional ethnography, which focusses on a single location. Here, in contrast to the classical viewpoint, following the recording process shows that building design is ongoing and extends beyond implementation through the years as the building ages. Research limitations/implications Due to the chosen research approach, the research investigated the most relevant events from the author’s perspective, which might extend in various ways. Future research is encouraged to investigate more events that support the empirical findings. Practical implications The paper provides a new angle from which building design networks can be followed through the transfer ethnography, which has implications for the recording and similar processes that necessitate the continuous following of actors. Originality/value The research suggests the transfer ethnography, which entails close and in-depth engagement with actors but changes with the transformation of a design while following the actors and networks’ shifts between the different locations. It is more delicate, attentive and indispensable considering the dynamics of design.

“…A large amount of point cloud data requires high computer configuration, and it often leads to computational crashes and crashes when processing, which affects the efficiency of point cloud data processing and use, and then affects the efficiency of 3D model reconstruction of point cloud data, so point cloud data streamlining is especially important. It is of great significance for the application and development of 3D laser scanning technology and points cloud data to compress the data volume of point cloud data to the maximum extent while ensuring that the target object model features and reconstruction are not affected [4]. In turn, it affects the efficiency of point cloud data 3D model reconstruction, so point cloud data streamlining is particularly important.…”

This paper provides an in-depth study and analysis of the measurement of construction projects using digital wireless mapping and illustrates it using examples. Static measurements determine the relative positions between ground points with high accuracy using a baseline vector network composed of simultaneous observations by multiple receivers, using the correlation of errors in space and time. Technology-based on this error correlation, then the distance observation error or coordinate observation error measured by the base station is sent to the mobile station through the data chain to correct the station star distance observation or coordinate value of the mobile station, improving the operational accuracy and efficiency of the mobile station. The measurement avoids the tedious measurement organization work and long-time data collection and postcomputation work of static measurement, and the coordinates of the mobile station can be obtained in real-time. To verify whether the accuracy of the 3D model built by the 3D reconstruction method integrating UAV and camera (air ground) images can meet the accuracy requirements for the installation deviation detection of the assembled building components, the 3D reconstruction of the physical objects was completed by this method. The accuracy of the 3D model built by this method was evaluated by comparing the measurement coordinates of 25 prearranged checkpoints in the 3D model with those of the total station. The test results show that the maximum point accuracy of the 3D model is 2.305 mm, and the average medium error is 2.147 mm, which can meet the accuracy requirements of the installation deviation detection of the assembled building components. The detection of installation deviation of wooden columns was completed by measuring the 3D model, and it was verified that the method is intuitive, fast, accurate, and batch completion of the deviation detection of axis position, elevation, small labour, batch detection of components, and contactless mapping compared with the traditional detection methods.

Purpose The practice of facility management (FM) has been evolving with the rapid development of pervasive sensing technologies (PSTs) such as sensors, automatic identification (auto-ID), laser scanning and photogrammetry. Despite the proliferation of research on the use of PSTs for FM, a comprehensive review of such research is missing from the literature. This study aims to cover the knowledge void by examining the status quo and challenges of the selected PSTs with a focus on FM. Design/methodology/approach This paper reviewed 204 journal papers recounting cases of using PSTs for FM. The reviewed papers were extracted from Elsevier Scopus database using the advanced search. Findings Findings of this study revealed that PSTs and FM applications form a many-to-many mapping, i.e. one PST could facilitate many FM applications, and one application can also be supported by various PSTs. It is also found that energy modeling and management is the most referred purpose in FM to adopt PSTs, while space management, albeit important, received the least attention. Five challenges are identified, which include high investment on PSTs, data storage problem, absence of proper data exchange protocols for data interoperability, a lack of mature data processing methods for data utilization and privacy of users. Originality/value This paper paints a full picture of PSTs adoption for FM. It pinpoints the promising explorations for tackling the key challenges to future development.
