The digitalization of the construction industry has immense potential for dramatically improving the industry’s practices. Concerning current measures in construction project management, the industry is still dependent on traditional construction methods. However, the application of fully automated techniques within the construction industry has not yet been a widespread practice. Thus, this may explain why there is a slow adaption of digital growth within the construction industry and specifically in developing countries. This study is aiming to investigate the acceptance of Building Information Modeling (BIM) and Augmented Reality (AR) integration in the construction industry. To achieve this aim, Technology Acceptance Model 3 (TAM3) was utilized. The scope was narrowed down to four developing counties (Malaysia, Egypt, Saudi Arabia, and Turkey) and a questionnaire survey was developed and distributed between construction professionals in those countries for data collection purposes. Exploratory Factor Analysis (EFA) was used to develop the TAM, and a regression analysis is used to validate it. The developed TAM3 showed that users control over BIM-AR and perception of easiness of use has the highest influence on their perception of the system usefulness, which would positively affect their intention to use the system. Additionally, unlike the findings of the original TAM3, three variables of Image, Perception of External Control, and Voluntariness illustrate new relations which can be considered as a novel outcome. The outcomes of this study can be used to evaluate the acceptance of BIM-AR Integration in the construction industry context, and the developed TAM3 can be used for the development of new BIM-AR applications in developing countries as it can predict the BIM and AR users’ acceptance.

“Green Buildings” are essential in being responsive to the challenges of climate change and global warming while inhibiting natural resources degradation. This demand requires specific attention to increase the adoption of green-certified buildings within the construction industry. Innovative tools and techniques are needed to meet global challenges and strategies set for Sustainable Development Goals of 2030 agenda. This paper provides an intensive review of the evolution of green buildings from a sustainable development perspective which investigates the current global adoption of green buildings. Systematic Literature Review (SLR) and Selective Critical Literature Review Analysis (SCLRA) methodologies were adopted focusing on the content analysis to develop more in-depth knowledge. The scope of this study enlightens the sustainable development goals and initiatives. This paper highlighted that there is still inadequate adoption of green buildings and their rating tools on a significant basis in developing countries. This research adds a method towards the better understanding of green buildings and current scenarios that shall be considered for future research.

Purpose Three dimensional (3 D) laser scanner surveying is widely used in many fields, such as agriculture, mining and heritage documentation and can be of great benefit for as-built documentation in construction and facility management domains. However, there is lack of applied research and use cases integrating 3 D laser scanner surveying with building information modeling (BIM) for existing facilities in Malaysia. This study aims to develop a scan to as-built BIM workflow to use 3 D laser scanner surveying and create as-built building information models of an existing complex facility in Malaysia. Design/methodology/approach A case study approach was followed to develop a scan to as-built BIM workflow through four main steps: 3 D laser scanning, data preprocessing, data registration and building information modeling. Findings This case study proposes a comprehensive scan to as-built BIM workflow which illustrates all the required steps to create a precise 3 D as-built building information model from scans. This workflow was successfully implemented to the Eco-Home facility at the Universiti Teknologi Malaysia. Originality/value Scan to as-built BIM is a digital alternative to manual and tedious process of documentation of as-built condition of a facility and provides a detail process using laser scans to create as-built building information models of facilities.

Abstract. The present paper is aiming to provide an actual state of the development of non autoclaved Agro-Industrial aerated concrete by using multiple ashes as improvement of thermal behavior for building. The feasibility of Agro-Industrial wastes as lightweight concrete by utilizing the Palm Oil Fuel Ash (POFA) as binder replacement and bottom ash as fine aggregate was investigated in this paper. Portland cement, bottom ash, aluminum powder and lime (Ca(OH)2) were used in this study. The POFA was used to replace Portland cement and Hydrated Lime at 0%, 5%, 10% and 15% by weight and aluminum powder was added at 0.75% dry weight in order to form bubbles. The compressive strength, water absorption, porosity and the thermal conductivity test were carried out after the concrete were water cured for 7 days and later being exposed to the air and water until 28days. The results show that the 20% replacements give the optimum strength of 7.143MPa and 30% give the best thermal conductivity with 0.48W/mK. Hence, this study aim, was to develop an agro-industrial aerated concrete good in insulation but having an optimum strength. Hence, it has been found that the more the percentage of POFA is added the lower the thermal conductivity since the pore structure is increasing and by the optimization done, 30% replacement has been chosen as the best mix design for Agro-Industrial Aerated Concrete.

The construction industry is ripe for disruption. With the vast pace of new technologies innovating the whole life cycle of construction, the revolution seems vital. The ideas of digitization and digitalization in Industrial Revolution 4.0 are currently entering the market in most industries including the construction industry. While most other industries have undergone tremendous changes recently, the construction industry has been reluctant about plenarily embracing the newly emerging technological adoption. Varying sophistication of construction, this paper was empirically evaluating large construction firms' point of view on challenges of the construction industry in the era of Revolution 4.0 using survey data form. The findings reveal that construction companies need to deal with the manifold PESTEL (political, economic, social, technological, environmental, and legal) challenges. By adopting the Revolution 4.0 hindered by lack of policies, financial problem, limited demand for innovation among large economic players, lack of trust towards foreign partners, and limited adaptability of foreign software. Clearly, this paper helps scholars and industry players to redefine the development of the construction industry into detailed strategic plans or policies in the future. In a nutshell, transforming the construction industry into digitization and digitalization might confront few challenges but the longterm benefits obtained throughout application should not be forgotten.
