Purpose The purpose of this paper is to assess the adoption of internet of things (IoT) element with the view of increasing usage so that benefits of convenience, increased performance and timely completion of work can be improved. This research was conducted so that there can be increase in the usage of IoT elements for construction performance and sustainability. Design/methodology/approach The study adopted survey design and various construction professionals were used to assessing the level of adoption of IoT elements. Convenience sample was used by distributing the structured questionnaire to registered professionals. Mean score, bar chart, Kruskal–Wallis H test, one-sample t-test and Shapiro–Wilk were used for analyzing the data gathered. Findings The findings revealed that wireless fidelity, visualization, wireless sensor networks, Bluetooth, electronic product code and internet protocol are the most adopted element of IoT in the industry. The study also shows that there are areas where there is no significance attached by construction professionals in the usage of IoT elements. These are data storage and analytics, barcode, Zigbee, gateway, near field communication and actuators. It is recommended that less significant areas can be improved through training and educating professionals about the whole concept of IoT and other design professionals. When the importance of IoT elements are understood it will help in the level of adoption. Originality/value This paper highlights the possible ways of increasing the adoption of IoT elements with a view to achieving better usage for convenience, high productivity of workers and easy access to information.

PurposeThe paper aims to analyze the application areas of augmented reality (AR) in the construction industry to enhance its usage level. The objectives are to assess the level of awareness of hardware and software devices of AR, examine the application areas of AR and reveal lagging areas in the construction industry.Design/methodology/approachA survey of construction professionals engaged in the built environment was sent a well-structured questionnaire in the study area. The professionals involved are project managers, architects, engineers, builders and quantity surveyors. The sampling technique used in selecting those professionals was convenience sampling. Descriptive and inferential statistics were used in analyzing the retrieved data.FindingsThe five most applied areas of Augmented Realities are Visualization and simulation of construction works; Project documentation; Project planning, monitoring and modification. The other two areas include on-site real-time information retrieval and health and safety measures. The findings also revealed the difference in the opinions of professionals among the variables. The results showed that there is significant difference in the opinions of the professionals regarding the application areas except one, that is automated measurement. Automated measurement has the same converging opinions of all professionals engaged in the study.Originality/valueThe study gives deep insight into possible areas where AR can be used in construction. The awareness level of hardware and software devices of AR was revealed by showing that those devices are upcoming in their usage. The areas of application of AR in construction are in their nascent stage. When there is proper implementation of this technology it will improve management in construction, minimize health and safety issues, and enhance the efficiency of workers through visualization and simulation.

PurposeThis purpose of the study is to evaluate areas of application of internet of things (IoT) in the construction industry, with the view of increasing the level of usage of technology. This will help in understanding the areas where IoT can be applied in the construction industry for better improvement.Design/methodology/approachA quantitative approach was adopted for this study, and the adopted questionnaire was structured on a five-point Likert scale to elicit the opinion of respondents in the areas of application of IoT in the construction industry. The respondents included are quantity surveyors, land surveyors, builders, architects and engineers. Bar chart, mean item score, one sample t-test and Kruskal–Wallis H test were used in analyzing the retrieved data.FindingsThe results showed that building information modeling, construction management, remote usage monitoring, equipment services and repair, construction tools and equipment tracking are areas where IoT is mostly applied in the industry. Site monitoring is the only factor that has significant difference in the opinions of professionals, while others do not have. One sample t-test revealed that three factors out of 12 do not have significance attached by professionals.Originality/valueThe study gives insight into different areas where IoT can be applied in the construction industry. It also highlights how its application can be improved through workshops, training, seminar and conference for construction professionals to keep themselves abreast of information and communication technology trends, especially in the aspect of IoT. The IoT adoption helps in accomplishing sustainable infrastructural projects with more convenience.

Purpose The paper aims to identify the critical barriers to augmented reality technology (ART) in the Nigerian construction industry to allow wider adoption. The objectives are to reveal those hindrances to the wider usage of ART so that the obstacles can be tackled and overcome. Design/methodology/approach A survey of construction professionals involved in the built environment was sent well-structured questionnaires in the study area. The professionals involved are quantity surveyors, architects, engineers, project managers and builders. Convenience sampling techniques were used in selecting those professionals. Descriptive and inferential statistics were used in analyzing the retrieved data. Findings The most ranked obstacles in adopting augmented realities are lack of technological awareness, difficulty in ease of ART system set up, the unwillingness of government and private bodies to invest in augmented reality research, lack of repository database, lack of portability for ART equipment system. The findings also revealed the difference in the opinions of professionals among the variables. The results showed that there is a significant difference in the opinions of respondents regarding 6 of the identified 15 variables. Originality/value The study gives deep insight into possible hindrances in the use of emerging technologies such as ART in construction. This study also enumerated some ways how these challenges can be tackled and solved in the Nigerian construction industry for better adoption and performance.
