Design for manufacture and assembly (DfMA) is an important part of the future of the construction industry due to the promise of speed of project delivery, quality control, worker safety, and waste minimization onsite via the purposeful design for manufacture and assembly offsite. However, the adoption of DfMA in Australia has been slow. This paper investigates the barriers prohibiting widespread uptake and how digital construction will be a catalyst for improving use on commercial-scale projects. A total of six leading experts were interviewed to elicit their opinions, and seven recent case studies of high-rise modular apartment and hotel buildings constructed by Hickory were cross-referenced as evidence of DfMA capability. The experts suggested that the reasons for slow adoption in Australia were community mindset, government regulations and incentives, planning and building codes, unionization and business politics, finance, and supply chain management. The case studies suggest that compatible building type and transportation distance are also factors. These barriers can be addressed by the clever integration of building information modelling tools with lean construction processes as part of a proposed strategy leading to smarter (more productive) and better (more sustainable) outcomes predicated on growth in digital construction practices. The paper concludes with a proposed framework for change that conceptualizes the ‘ecosystem’ needed to support widespread DfMA in the Australian context, including the paradigm shift from building to manufacturing/assembly, the displacement of workers from onsite to offsite activity, and the expansion of interdisciplinary design and construct collaboration.

Lean Construction is one of the methods used to improve control over construction projects by eliminating waste in time and materials. Lean Construction is an adaptation from the Lean Manufacturing principles to the construction industry. The purpose of this article was to review the case studies published in 2018 in the Inspec database to find out where Lean is being implemented and how. The article approach by setting the search criteria first and then inspect the result to find the non-related results and eliminate it. After that, the article was reviewed and summarized. The article verifies each article finding; however Lean Construction and Building Information Modeling (BIM) are relatively new for the construction industry and they still need more time to be adopted widely and to be applied on a lower-cost budget. However, the discussed cases show a promising future for these technologies.

Over the years, the construction industry has been evolving to embrace the delicate balance between buildings and a sustainable environment by optimizing resource use to create greener and more energy efficient constructions. Sustainable building design and optimization is a highly iterative and complicated process. This is mainly attributed to the complex interaction between the different heterogenous but heuristic construction processes, building systems and workflows involved in achieving this goal. Augmented Reality (AR) has rapidly emerged as a revolutionary technology that could play a key role towards improving coordination of sustainable design processes. AR makes possible the real-time visualization of a threedimensional (3D) building prototype with linked design information in a real-world environment based on a twodimensional drawing. From past research, it is evident that this technology relies heavily on a common data environment (CDE) that syncs all construction processes with their related building information in one central model. However, due to the fragmented nature of the construction industry, different domain experts generate and exchange vast amounts of heterogenous information using different software tools outside a CDE. This paper therefore investigates the performance gap that exists within Malaysia’s construction industry towards using linked building data (LBD) with AR to improve the lifecycle sustainability of buildings. The results of this study clearly delineate how current construction practices in Malaysia do not favor the use of AR however, stakeholder perception is positive towards adoption of workflows that link heterogenous building data to streamline AR with sustainable building design and construction.

Building information modeling (BIM) and modular construction are important technologies for construction industry sustainability. This study proposes a relational matrix of key activities and BIM tasks of modular construction projects to analyze practical BIM tasks in Korea. To achieve this objective, 11 key activities and eight BIM tasks are identified through a comprehensive literature review and expert interviews. Then, the relational matrix of key activities and BIM tasks is proposed, and the BIM tasks in the matrix are analyzed in terms of necessity and efficiency using 5-point Likert scales. Finally, the matrix with the BIM utilization index is suggested. As a result, the average BIM utilization index is 0.80 in the off-site phase, and the index results show that 3D shop drawings have the highest index. In the on-site phase, the average BIM UI is 0.73 and the integration of a 4D model with quantity take-off is the most efficient at 0.85. Additionally, from the decision-maker’s perspective, the priority through the index presented helps in making decisions and in practical BIM execution planning. The proposed matrix is a practical reference for decision-makers considering the application of BIM in modular projects, and it contributes to a sustainable construction industry.

The construction industry is one of the most hazardous industries, with a high number of working injuries and fatalities. A special issue for occupational accidents in the construction industry is the use of scaffolds, which is usually attributed to falls from height. Research and practice have demonstrated that decisions made upstream from the construction site can influence construction worker safety. Therefore, it is crucial to assess the risk levels for different construction stages on scaffolding, with various work trades, aiming to prevent the occurrence of fall accidents. The use of new techniques and methodologies, such as Building Information Modeling (BIM), is of major importance. The growing implementation of BIM in Architecture, Engineering and Construction (AEC) is changing the way safety can be approached. This study reviews the existing literature about BIM and construction safety on scaffolding, to explore useful findings and detect knowledge gaps for future research. Despite the enormous evolution of research and technological innovations based on BIM for construction safety, there is still a flagrant lack of knowledge and solutions for identifying hazards related to construction on scaffolding.

Unforeseen ground conditions are some of the main contributors to construction cost over-runs and late completion. Recent research trends have witnessed the scopes of building information modeling (BIM) technology being extended to subsoil and substructure constructions, or simply known as geotechnical BIM. This paper aimed to explore the procedures of developing 3D subsoil models through two case studies in Malaysia. The geotechnical BIM processes were performed by commercial software, AutoCAD Civil 3D 2017, with the extension of the Geotechnical Module. The modeling procedures can be divided into three main stages, namely data collection, data interpretation, and data visualization. The subsoil models were successfully developed at different levels of detailing to serve for different applications. The results showed that the 3D subsoil modeling required huge modeling and computational efforts, particularly when dealing with tropical residual soil profiles in Malaysia that are highly intricate. Thus, an adequate soil strata generalization was required to simplify the generated subsoil model. Data collection and management was identified as one of the main challenges of promoting geotechnical BIM in Malaysia at a macro-scale. Despite the challenges, successful implementation of the geotechnical building information in the present case studies were proved to be capable of promoting interoperability of soil data, which is an essential element in sustainable construction.

Under the concept of sustainable construction it is necessary to establish harmonized indicators, standards and methods for assessing the impact of building products and technological processes of the construction industry on the environment. One of the basic commodity that have a significant impact on the environment is construction waste and his recycling options. Concrete aggregate (RCA), which can be made from concrete elements, has a great potential in reducing the volume of landfills and full re-using of concrete rubble. It can also fulfill sustainability criteria for construction by the re-use of this stony concrete components. The study takes into account local characteristics RCA, but the aim is to globalize outcomes and evaluate them, especially for parameterization used in the design phase of building information modeling.

This paper examines the drive in the construction industry to source materials for new construction sustainably. It examines the key drivers that sustainable construction entails but also looks at the crucial impact that over-specifying can have on the performance of concrete in the field. Sustainability is, however, just one concern to the modern Engineer, and ensuring the concrete can be placed and compacted adequately is also a very real concern, especially where visual concrete is concerned. The paper examines some of the issues around sustainability and also looks at several case studies where concrete has not performed as expected and has caused very real problems in the field, when using secondary cementitious materials (SCMs) in conjunction with superplasticiser. The paper concludes with some guidance on how to achieve the best of both aims sustainability and durability, while avoiding some of the pitfalls that can occur.

The construction of high-rise building projects is a dangerous vocation due to the uniqueness and nature of the activities, as well as the complexity of the working environment, yet safety issues remain crucial in the construction industry. Digital technologies, such as building information modeling (BIM), have been identified as valuable tools for increasing construction productivity, efficiency, and safety. This research aimed to mitigate the accident safety factors in high-rise building projects via integrating BIM with emerging digital technologies in the construction industry, such as photogrammetry, GPS, RFID, augmented reality, (AR), virtual reality (VR), and drone technology. Qualitative research was conceived in the ground theory approach. Forty-five online interviews with construction stakeholders and qualitative data analysis were carried out using the NVivo 11 software package. According to the findings, interviewees were more motivated to use photogrammetry and drone technologies in high-rise building projects in order to increase construction safety. Positive, negative, and neutral attitudes about BIM integration with emerging digital technologies were discovered. Furthermore, a research framework was developed by consolidating research findings that articulate the measures and future needs of BIM integration with other digital technologies to mitigate construction accidents in high-rise building projects. The framework also renders practical references for industry practitioners towards effective and safer construction.

The construction industry consumes an enormous amount of global resources and produces more waste than any other sector. The need to move toward sustainable development in construction requires significant changes in construction and demolition (C&D) waste management. The estimation of waste, recycling materials and reusable components could be vital in waste management, achieving huge efficiency in the construction industry. Moreover, a typical building comprises of an extensive amount of materials and components with various characteristics. This study proposes a Building Information Modelling (BIM)-based system to allow the circular economy by storing information of the materials and components of buildings and by effectively managing the recycling of materials and reuse of components. A tool which serves as a Material and Component (M&C) bank was developed with PHP and MYSQL by making use of a web browser able to extract the materials and component information of a building through the BIM model. This information is vital for several uses such as quantification of C&D waste and assessing for the design for deconstruction. It can also be used to obtain the information of the reusable condition of the components and instructions for the reconstruction.
