“…The findings of this study demonstrate that GPS is a reliable and robust outdoor construction workforce tracking technology. An uninterrupted presence time analysis was also employed to improve further the estimation accuracy (Vrijhoef, 2019;Zhao et al, 2019Zhao et al, , 2021. The uninterrupted presence time concept assumes that workers perform productive work if they remain in the work area for more than a certain amount of time (Zhao et al, 2019).…”

PurposeActivity sampling is a technique to monitor onsite labourers' time utilisation, which can provide helpful information for the management level to implement suitable labour productivity improvement strategies continuously. However, there needs to be a review paper that compiles research on activity sampling studies to give readers a thorough grasp of the research trend. Hence, this paper aims to investigate the activity sampling techniques applied in earlier research from the angles of activity categories formation, data collection methods and data analysis.Design/methodology/approachThe method used in this paper is a systematic review guided by the PRISMA framework. The search was conducted in Scopus and Web of Science. The inclusion and exclusion criteria were applied, selecting 70 articles published between 2011 and 2022 for data extraction and analysis. The analysis method involved a qualitative synthesis of the findings from the selected articles.FindingsActivity sampling is broadly divided into four stages: targeting trade, determining activity categories, data collection and data analysis. This paper divides the activity categories into three levels and classifies the data collection methods into manual observation, sensor-based activity sampling and computer vision-based activity sampling. The previous studies applied activity sampling for two construction management purposes: labour productivity monitoring and ergonomic safety monitoring. This paper also further discusses the scientific research gaps and future research directions.Originality/valueThis review paper contributes to the body of knowledge in construction management by thoroughly understanding current state-of-the-art activity sampling techniques and research gaps.

“…Zhao et al (2019) proposed the concept of uninterrupted presence of workers in work locations which they claimed correlated with value-adding time. They later expanded the concept to task level (Zhao et al, 2021) and defined presence index as the share of uninterrupted presence during task duration. These metrics are used to identify opportunities for improvement in this research.…”

The construction industry is improving its processes targeting to increase productivity. Lean construction has been in use for decades, and now lean is expanding in the form of takt production. Takt production gives clear steps to apply lean in daily construction projects. Takt production transfers the improving flow from the manufacturing industry's conveyor belts to construction sites.Digital situational awareness systems are good examples of new digital solutions in construction. They provide possibilities to construction stakeholders to better control and improve their processes by visualizing waste and helping find the root causes of problems to be fixed.This paper aims to study how digital awareness systems support takt production in construction projects. This study is a qualitative case study based on a project implementing a digital situational awareness system and relies on project staff interviews and the data available on the project. The project team has successfully improved takt production with digital awareness systems for revealing and fixing waste. They have successfully improved the productivity of tasks. Digital situational awareness systems can play an important role in the continuous improvement of processes in the construction industry.

“…Our current research uses the same BLE-based real-time tracking system that Zhao et al (2019); Zhao et al (2021) used in their previous study. In the model, BLE beacons were used that could be associated with construction workers who had previously agreed to be monitored.…”

Improved productivity and the elimination of waste are key goals for lean methods in construction production control. One such lean method is a kit-based logistics management in which task-based materials are delivered just-in-time and aligned with assembly operations on-site. Digital platforms could enable a situational awareness of work and material flows, potentially increasing the benefit and applicability of kitting. The aim of the current research is to utilize a real-time indoor tracking of material and labor flows to evaluate an assembly kit–based management of construction projects. We propose a linked data framework to connect labor, material, and scheduling information to integrate heterogenous data. The contribution of the study is threefold: first, a feasible method is developed to enable real-time detection of work and material flows inside the building for logistics management purposes. Second, several key performance indicators for effective evaluation of kit-based production flow in construction are provided, which allows management to tackle root causes of problems and to enhance timely and productive logistic solutions. Thirdly, by applying the linked data method, the study introduces a novel approach to integrate heterogenous data from both indoor tracking and schedules.
