Summary: This study presents a novel method for work estimation, aiming to develop an accurate and reliable work classification algorithm for monitoring construction sites. Deep learning algorithms are utilized to classify multivariate time-series data collected from inertial measurement units mounted on the worker. Three models with different window sizes are developed, and the best performing model achieves 90% accuracy and an F1 score of 0.876. The model is analyzed and pruned using expected gradients for feature selection, reducing the input space by 60% equivalent to 3 sensors. This is an initial step towards a general model for classifying productivity measures for workers on construction sites, which can provide valuable input for monitoring activities and forecasting productivity.

Summary: The results suggest that changes in water productivity are mainly driven by changes in labor productivity and capital intensity, rather than improvements in water efficiency. Therefore, it is not recommended for policymakers to use water productivity as an indicator for monitoring progress in efficient water management. Instead, indicators independent from economic development should be used.

Summary: Maize yields can be improved through a combination of individual techniques and management practices, but the full potential benefits are best realized when complementary practices are integrated. Complementary management practices can improve yields, but if not combined properly, they may actually decrease yields. It is important to pay attention to the combination of crop protection and integrated management for optimal maize production.

Summary: The aim of this study is to measure the impact of factors affecting construction labor productivity during and after the COVID-19 pandemic in Turkey. The results show that legal obligations such as social distancing and limitations on the number of workers have had a significant impact on labor productivity. Difficulties in receiving payments on time, loss of income, and financial hardships are also major factors contributing to decreased worker performance.

Summary: Researchers have utilized system dynamics (SD) as a modelling tool to understand systems with different levels of dynamism and complexity. However, there is a lack of comprehensive literature review on the application of SD in construction engineering and management (CEM). This study conducted a systematic literature review and content analysis to investigate the applications of SD in CEM research. The findings provide insights into the research areas where SD is mostly used, the evolving trends, and the potential for future research in improving SD modelling capabilities.

Summary: This study focuses on resilience factors in post-disaster reconstruction projects and develops a conceptual framework to guide their strategic selection and application. Through systematic review, it identifies 24 resilience factors grouped into five criteria, including governance, innovations, reconstruction approaches, resource management, and stakeholder expectations. The findings emphasize the importance of client and end-user participation in construction management and highlight the need for a comprehensive approach to resilience in the built environment.

Summary: This study investigates the interrelationships between causes of cost overrun using interpretive structural modeling (ISM) and proposes strategies to tackle the causes considering their interactions. The results show that price fluctuation, claims, execution delay, delay in payment, and change order directly result in cost overrun, while corruption and poor contract management are the root causes. The study also suggests paying more attention to the precontract phase of the project to address these issues.

Summary: Despite the benefits of digital technologies (DT) to enhance construction industry performance, the implementation of DT in construction practice has been slow. This study developed a readiness model and self-assessment tool to evaluate DT readiness in construction companies based on a questionnaire survey. The study identified "organizational culture," "leadership and top management support," and "top management's perception" as the three most critical indicators of DT readiness in construction companies.

Summary: This study aims to identify critical barriers for construction organisations to adopt digital technologies (DTs) and to demonstrate relationships between organisational characteristics and the perceived DTs adoption barriers. By adopting an explanatory sequential design, combining the advantages of quantitative and qualitative data, this study collected data through literature review, questionnaire survey, and semi-structured interviews. The findings identified eight critical barriers, classified into technical, environmental, and social dimensions, and established a theoretical framework and a model to link organisational characteristics with barriers to DTs adoption. This study contributes to the literature on construction innovations and provides a foundation for future empirical research into DTs adoption and diffusion.
