This study takes a critical look at Takt planning and takt control (TPTC) by analysing a successful case project. In the study, the digital system architecture and collected data are used for providing a process breakdown and analysis in terms of waste and potential root causes. The paper shows how vulnerable the TPTC is for disruptions caused by a lead waste, making-do/task diminishment, and ad-hoc tolerance management. Based on the digital footprint of the project, an explanation is given why good results in terms of money, customer satisfaction, time and quality were achieved even though the takt was practically lost towards the end of the project. The results indicate that the excellent outcome of the project was not based on TPTC and steep learning curve. Instead, the results were achieved by exploiting the real-time situation awareness provided by the digitalised smart site and disciplined use of applications, as well as by a pragmatic approach to planning and leading work on-site. The validity of the results is limited as the conclusions are drawn based on only one TPTC project.

“…Many technologies have been applied for resource tracking in construction, such as passive RFID (Costin et al, 2012), ZigBee (Liu et al, 2007), BLE (Zhao et al, 2017), (Dror, 2018), magnetic field (Park et al, 2016), and Global Positioning System (GPS) (Alarifi et al, 2016). GPS is a mature technology for tracking, but it is not suitable for indoor positioning (Liu et al, 2007).…”

Automatic resource location monitoring in construction projects empowers managers to make data driven decisions that improve project workflow. Monitoring data can be processed to measure workflow quality and thus for better understanding of effectiveness and efficiency. We compare two methods for deployment of Bluetooth Low Energy (BLE) beacons for indoor resource monitoring -mobile beacons and fixed gateways (MB) vs. fixed beacons and mobile gateways (FB). BLE beacons can be fixed to walls or carried by workers, and can be fixed to material containers and equipment. Using gateways, such as raspberry pi computers or smartphones, one can easily and automatically monitor resource locations. Several field experiments were conducted, both in the laboratory and in construction sites in Finland, Israel, Peru, Netherlands and China. Technical aspects such as setup, direct cost, feasibility and accuracy were compared for two methods -mobile beacons and fixed gateways vs. fixed beacons and mobile gateways -and the performance of each method in providing the data needed for lean construction workflow assessment was assessed. Both methods are effective in monitoring resource locations but differ in their feasibility of implementation in construction sites and in the utility of the data they provide in terms of identifying value adding activities.

“…Over the last past years, previous studies have confirmed that there is substantial room for productivity improvement in construction industry in terms of scheduling, labor training and quality control (Arditi and Mochtar 2000). Therefore, there is a need for automatic-generated information for onsite resource management such as labors, materials and equipment (Zhao et al 2018).…”

The construction jobsites are regarded as highly dynamic and chaotic environment for both workers and management. To ensure efficient task performances, workspace is a key resource in construction sites. Nowadays the technology has enabled better management of onsite resources through location-based methods within lean construction principles, such as Location-Based Management System (LBMS) and Takt planning. Those methods aim to optimize workspace in construction sites consisting of multiple tasks and to eliminate waste related to product and labour flows. To contribute to enhancing those lean construction approaches with attempts to obtain real and objective data, we have developed a real-time positioning system based on Bluetooth Low Energy (BLE) technology where coordinates of workers can be obtained, and heat maps of task-related workspace are generated in real time. This paper aims to develop automated process of generation of workspace based on coordinates of workers and to explore various uses of workspace heat maps to serve the purposes of lean construction principles. The successful implementation of the system in China is analysed and the results suggest that heat maps which use dimensional and temporal positioning data, could be an efficient and convenient method to define workspace of crews onsite.
