In recent years, due to the rapid development of the fourth industrial revolution and new platforms of information technologies, intelligent systems have received widespread attention in many industries and have brought the potential to improve the efficiency of the construction industry. These facts led to the appearance of a new concept in construction industry called Construction 4.0. Therefore, this article seeks to explore the state of implementation of Industry 4.0 technologies in the construction industry and analyze their impact on the formation of the Construction 4.0 concept. In order to achieve the aim of this article, a literature review was conducted using the most relevant publication in this field. Moreover, authors carried out a bibliometric analysis among 195 selected research articles related to the Industry 4.0 and Construction 4.0 to identify interconnections between these concepts. The results show that Industry 4.0 has the greatest impact on productivity growth in construction and that interest in digital technologies is growing every year, but their penetration into the construction industry is currently slow and limited. The authors suggest that further research needs to be focused on future ethical issues that may arise and on synergies between Construction 4.0 technologies.
Creating continuous workflow and reducing variability of construction processes is one of the essential principles of Takt Time system. The Takt Time Planning is a powerful lean tool that creates a continuous flow of people, materials, and resources, therefore it is recognized as a technology with great potential for process innovation in construction. A takt is a demand-driven pace or rhythm of work, which ensures that professionals work at the same speed to free up workspace within standard time frames, leading to a more optimized production process. The main purpose of this article is to explore the practical application and influence of Takt Time Planning on the productivity and efficiency of construction projects by providing an overview of selected case studies. Results show that Tact Time helps to establish a continuous flow and, as a result, reduce waste, reduce the duration and number of inventory buffers, and therefore reduce costs of construction projects.
Innovation initiatives are crucial for any industry because their future growth depends on it. Innovative technologies that can have a great impact on the construction industry, such as building information modelling, automation and robotics, augmented reality, virtual reality, simulation, internet of things were reviewed in this article. In spite of that, innovation implementation in the construction sector has generally lagged behind other industry sectors affecting the productivity as well. The governments are aiming to improve this through increasing the level of investments into manufacturing and innovative research in this area. This article reviews the process of adopting innovative technologies and the reasons why there are obstacles to their implementation. It is expected that integration between machines and humans will enhance human capabilities, allowing them to concentrate on more creative and value added, socially important activities in the future. There is also need of changing thinking in order to transfer the results of these technological studies into production in the construction industry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
