The construction of residential projects constitutes a major portion of the building activities in the State of Kuwait. This paper presents the findings of a research project, which aims to determine the causes of delays and cost‐overruns in the construction of housing projects in Kuwait. The owners of 450 residential projects (just completed or near completion), spread over 27 systematic‐randomly selected metropolitan districts, were personally interviewed. Data on owners' socio‐demographic traits and project characteristics, including those involving time and cost overruns, were obtained. The paper highlights the impacts of construction materials on time‐delays and cost‐increases. Project‐related variables affecting the on‐time delivery of materials to the construction site are examined and quantified. The material selection‐time, type of materials, their availability in the local market and the presence of a supervising engineer, all demonstrated a statistically significant impact on the on‐time delivery of materials to construction sites.

In recent years, 3D printing technologies have been widely used in the construction industry. 3D printing in construction is very attractive because of its capability of process automation and the possibility of saving labor, waste materials, construction time and hazardous procedures for humans. Significant researches were conducted to identify the performance of the materials, while some researches focused on the development of novel techniques and methods, such as building information modeling. This paper aims to provide a detailed overview of the state-of-the-art of currently used 3D printing technologies in the construction areas and global acceptance in its applications.

The working principle of additive manufacturing in construction engineering (CE) is presented in terms of structural design, materials used and theoretical background of the leading technologies that are used to construct buildings and structures as well as their distinctive features.

The trends of 3D printing processes in CE are very promising, as well as the development of novel materials, will gain further momentum. The findings also indicate that the digital twin (DT) in construction technology would bring the industry a step forward toward achieving the goal of Industry 5.0.

This review highlights the prospects of digital manufacturing and the DT in construction engineering. It also indicates the future research direction of 3D printing in various constriction sectors.

In the construction industry, it is well known that there is a relatively large volume of material being wasted due to a variety of reasons. The problem of material waste on construction sites is not an isolated issue and is of environmental concern. Therefore, waste minimization has become an important issue in the construction industry. The aim of this research was mainly to identify the pre‐cast contribution to the construction waste minimization in the Sri Lankan construction industry, through a comparison of material waste arising from pre‐cast, ready‐mixed and site‐mixed concrete.

Data were collected from 27 building construction projects and three concrete elements: slabs, beams, and columns, were considered to quantify construction waste. To compare the wastage due to pre‐cast involvement with other types, three categories of building projects were used, including projects using pre‐cast concrete elements, in situ concrete elements – site mix, and in‐ situ concrete elements – ready mix.

The study found that mean wastages of cement, sand and metal in PC elements amounted to 5.34 per cent, 13.86 per cent and 7.62 per cent respectively showing lower values compared with the material wastages in the other two technologies (in situ concrete elements – site mix, and in situ concrete elements – ready mix). Further, statistical t‐test and ANOVA were carried out to ascertain whether these results were significant. Results revealed that there is a significant waste reduction when pre‐cast concrete is used.

The paper provides useful information on pre‐cast contribution to the construction waste minimization in the Sri Lankan construction industry.

Although the adverse effects of construction activities on the environment and the need for sustainable construction practices are recognised in both research and practice, any significant shift in the selection and use of construction materials from the sustainability perspective has not taken place in many building projects. Still, conventional construction materials are widely used in building projects in both developed and developing countries. This study attempts to identify the main barriers to the use of sustainable materials in building projects in an advanced economy such as Australia.

This study adopted a questionnaire survey approach to examine the main reasons behind the low usage of sustainable materials in building projects. Based on the relative importance index, exploratory factor analysis and multinomial logistic regression analysis, the study examined the main barrier measures and barrier factors to the use of sustainable materials in building projects.

The findings reveal that critical barriers to the use of sustainable materials are related to cost and profit considerations, the unwillingness of the key stakeholders to incorporate these materials into building projects, lack of incentives and government policies. The factor analysis reduced the critical barrier measures into three factors: techno-economic considerations, cost and delay concerns and resistance to use. Furthermore, multinomial regression analysis based on the extracted factors identified techno-economic considerations as the main barrier factor to the use of sustainable materials in building projects.

The empirical results of this research can inform construction practitioners, organisations and policymakers on how to increase the use of sustainable building materials in the construction industry.

Identification of barriers to the use of sustainable building materials is a prerequisite to improve their uptake and use in the construction industry. The study fills a gap in the existing research on the use of sustainable materials in building projects in Australia.

Construction is possibly one of the most cost orientated industries in any economy. The primary mode of supplier selection has always tended to be on the basis of lowest material or service cost at point of consumption. Indeed, this remains the case even in the post‐Latham (1994) and Egan (1998) world in which we live. In general, construction cost estimates are based on a straight ‘take off’ of the quantities required. All further ‘other’ costs in the form of overhead, profit, labour and wastage are consolidated into the cost of the materials. Construction is unique within the various industries making up a modern economy in that the bulk of the materials and components that it uses are of relatively low value while being of high volume. Consequently, a significant proportion of the ‘other’ costs associated with materials purchases must be in the form of transportation from the point of extraction and / or production to the point of consumption. This paper provides an overview of the hidden costs associated with the transportation of construction materials within the industry and proposes improved methods of managing the logistics of the construction process e.g. reverse logistics, in order to reduce costs and increase the basic sustainability of the construction process.

Urbanization and globalization in India have led to the depletion of resources and degradation of the environment to meet the demands. Because of these issues, researchers and practitioners have begun to study various strategies to reduce the level consumption of resources to utilize it for present and future needs. In pursuit of finding solutions to the problems, sustainable building construction is found as the best key to avoid depletion of resources. Sustainable material selection is found as a vital strategy in construction. The paper aims to discuss this issue.

A three-phase methodology is proposed for framing the assessment model for construction industries to select materials for construction. In the first phase, a total of 23 sub-criteria of triple bottom line (TBL) and four brick materials as alternatives were identified. The second phase finds the weights and ranks of criteria and sub-criteria using the best worst methodology (BWM) the third phase involves ranking of materials concerning sub-criteria weights determined in phase II using Fuzzy Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS).

The objective of study is fixed to identify the criteria list for the selection of material in construction industries from the literature review especially for Indian construction industries; to rank the criteria for selection of materials with the help of the BWM approach; and to prioritize the identified materials in the view of sustainability with the help of Fuzzy TOPSIS in construction industries perspective. This study analyzed and choosing right sustainable materials by the three pillars of sustainability which are the environment, economic and social, also called TBL, for Indian construction companies by framing a sustainable material assessment model.

The results of this study facilitate to frame an assessment model for evaluating and selecting sustainable building materials.

The research is unique because it addressed waste minimisation strategies for the building construction industry and for the industrial and heavy/highway construction industries.

Building information modelling (BIM) and radio frequency identification (RFID) technologies have been extensively explored to improve supply chain visibility and coordination of material flow processes, particularly in the pursuit of Industry 4.0. It remains challenging, however, to effectively use these technologies to enable the precise and reliable coordination of material flow processes. This paper aims to propose a new workflow designed to include the use of detailed look-ahead plans when using BIM and RFID technologies, which can accurately track and match both the dynamic site needs and supply status of materials.

The new workflow is designed according to lean theory and is modeled using business process modeling notation. To digitally support the workflow, an integrated BIM-RFID database system is constructed that links information on material demands with look-ahead plans. The new workflow is then used to manage material flows in the erection of an office building with prefabricated columns. The performance of the new workflow is compared with that of a traditional workflow, using discrete event simulations. The input for the simulations was derived from expert opinion in semi-structured interviews.

The new workflow enables contractors to better observe on-site status and differences between the actual and planned material requirements, as well as to alert suppliers if necessary. The simulation results indicate that the new workflow has the potential to reduce the duration of the material flow processes by 16.1% compared with the traditional workflow.

The new workflow is illustrated using a real-world-like situation with input data based on expert opinion. Although the workflow shows potential, it should be tested on a real-world site.

The new workflow allows project participants to combine detailed near-term look-ahead plans with BIM and RFID technologies to better manage material flow processes. It is particularly useful for the management of engineer-to-order components considering the dynamic site progress.

The research improves on existing research focused on using BIM and RFID technologies to improve material flow processes by showing how the workflow can be adapted to use detailed look-ahead plans. It reinforces data-driven construction material management practices through improved visibility and reliability in planning and control of material flow processes.

The purpose of this paper is to determine the environmental performance of construction trends in houses in central Mexico by assessing the type and quantity of material used in construction elements.

Three reference Mexican houses are used for the analysis: a traditional house, a house with mostly masonry elements, and a house with mostly concrete elements. The reference houses indicate the construction trend followed in central Mexico. Quantitative analysis of the types and weights of various materials used to construct the houses is undertaken. The environmental performance is measured according to their sustainability potential. The indicators used are based on the Three Step Strategy, which sets the steps needed to achieve sustainable construction: use fewer materials, use renewable materials and be efficient with the remaining need.

The analysis shows that there is a trend to use faster and cheaper construction processes, which are often concrete and prefabricated elements, especially for dwellings built in series. Although this has the positive impact of decreasing the stress on housing demand, it might have negative impacts on the environment because more energy‐intensive and artificial materials are used. In addition, the low homogeneity of these materials decreases the potential of construction elements to be reused or recycled.

The findings of this study aim at providing more information to practitioners on the sustainability of material choices during the design process. Thus practitioners will be better informed to design more environmentally sustainable buildings. The results are based on analysis of data from Central Mexico but may have relevance to other parts of the world.

The study provides quantitatively derived evidence to support sustainable design decisions.
