The purpose of this paper is, first, to summarize six studies which analyze the key characteristics of different types of employees. Three types of employees found in workplaces all over the world are identified as “Necessities,” “Commoners,” and “Parasites” and, second, to combine the results of these studies in order to identify the key traits and behaviors that characterize each type of worker across a variety of social and cultural settings.

For starters, three types of employees are defined. First, a person is a Necessity if s/he is irreplaceable and critical to the functioning of an organization. Second, a Commoner is a person of normal ability and talent who has no significant impact on organizational processes. Last, Parasites are detrimental freeloaders who damage the functioning of an organization. To identify the principal characteristics of these three types of workers, a group of researchers led by the first author conducted six studies in which they collected survey data from undergraduate and graduate business students in the USA, India, Korea, Chile, and Japan.

The authors note the points of commonality and difference across the data sets, and offer their thoughts on future research in the area. The perceptions of what characterizes really good workers (people of Necessity) and very bad workers (Parasites) appear to be the same in all five countries. The picture painted for the Commoner across all data sets, however, is not as clear‐cut.

The study described in this paper helps to explain both similarities and differences in employee characteristics between and among workers in different countries and cultures.

Unlike the design or planning phases, the construction phase necessitates the coordination of multiple project stakeholders, real-time problem-solving and effectively managing physical resources under fluctuating site conditions. However, recent green rating systems are not yet designed to accommodate the unique nature of this stage. Thus, this study aims to develop an empirical measurement model to evaluate the performance of green construction sites (GCS), focusing on the Vietnamese construction industry.

Initially, a list of assessment criteria was identified by reviewing previous studies and semi-structured interviews. After that, a questionnaire survey was used to collect practitioners’ views regarding GCS performance. The 155 valid responses were analyzed employing the fuzzy synthetic evaluation (FSE) method.

The findings showed that the performance of GCS in Vietnam is at a moderate level, with a GCS index of 5.48. Indeed, the human-related factor was the most significant performance group for GCS in Vietnam. Construction site, energy, innovation and material-related factors were among the average performance factors. Moreover, water and waste-related factors were among the lowest performance factors.

This study highlights the importance of human-related factors, such as worker safety and environmental training, in achieving effective GCS performance. It is recommended that governments should enforce stricter guidelines on using low-embodied carbon materials, sustainable sourcing and effective waste management to improve GCS performance. Neighboring countries can also use valuable insights from this study to enhance their GCS performance.

Construction industry hesitates to associate Green concepts on building projects mainly due to its high initial investment cost. Even if it is economical in the long run, often the benefits are suppressed with the costs generated through non-value-adding activities in the construction process. Lean construction principles have proved to eliminate such waste while enhancing the construction process. Thus, the purpose of this paper is to explore the applicability of the integration of Lean and Green concepts in the construction industry.

The fundamental principles of both Lean and Green construction were evaluated through an extensive literature survey. A qualitative approach was adopted, and thus, based on the literature findings, expert interviews were conducted with professionals having experience in both Green and Lean concepts. Furthermore, the findings were validated through experts to analyse the adaptability of the integration. Content analysis technique was utilised with NVivo software programme to analyse the findings.

The integration of the Green concept was found to alter the traditional application of Lean concept, considering the social and environmental aspects without limiting to economic considerations. The study revealed that the perception of the Sri Lankan stakeholders towards the application of integrated Lean-Green concept is focussed on a positive direction. As a result, the identified enablers to implementing the integrated concept supersede the barriers by confirming the appropriateness of the application in the local construction industry.

A framework was developed through the findings to guide the implementation of integrated Lean-Green application in Sri Lankan context.

This study explores the relationships among sustainability implementation barriers (resource, managerial and regulatory barriers), sustainability practices (sustainable construction materials, sustainable construction design, modern construction methods and environmental provisions and reporting) and sustainability performance (environmental, economic and social) in hill road construction (HRC).

Primary data were collected from the 313 HRC practitioners with the help of a questionnaire, and research hypotheses were tested employing structural equation modeling.

The findings reveal a mixed effect of sustainability implementation barriers. Resource (managerial) barriers are negatively related to all practices except environmental provisions and reporting (sustainable construction materials), while regulatory barriers only negatively impact modern construction methods. On the other hand, all sustainability practices positively impact environmental performance, whereas economic (social) performance is positively influenced by all practices, except environmental provisions and reporting (modern construction methods), and positively affects economic performance.

In order to transform HRC toward sustainability, the barriers to sustainability implementation, sustainability practices and performance need to be understood by practitioners; however, the relationships have not previously been empirically assessed in extant literature. Besides, past research appears to be predominantly focused on the environmental aspect, thereby neglecting economic and social aspects. This study is a modest attempt to bridge these research gaps.

The purpose of this paper is to explore the synergies among reverse logistics supply chain (RLSC), quality management (QM) and information management (IM) concepts to enhance the effectiveness of demolition waste management (DWM) practices.

A systematic literature review was conducted using 70 articles published between the years of 2006 and 2017, which were subjected to descriptive and thematic analysis.

The descriptive analysis established that the RLSC concept was dealt within the majority of the publications (61 per cent), followed by concepts related to quality in RLSC (24 per cent). Only 14 per cent of the articles were based on IM concepts related to RLSC. Quality and information are interrelated in the effective implementation of RLSC. The thematic analysis demonstrated that there is a need for using quality parameters in a regulatory environment in an information-based environment. Based on the findings, future research directions were developed.

The study encourages researchers to identify novel directions by combining these three concepts. The study developed a future research agenda regarding use of building information modelling (BIM) for existing buildings under novel technologies; analysis of secondary market demand and supply; and assessment of cost and safety management with quality in a BIM-enabled environment.

The practical implications include the application of sustainable management principles based on stakeholders and the regulatory environment.

Integration of the three concepts is an emerging area. This integration developed a robust approach to achieve QM in RLSC operations under a sound information flow enabling the optimisation of DWM.

The purpose of this paper is to describe the process through which an organization develops organizational capabilities by tapping the technical skills and social skills of its employees in the use of Building Information Modeling (BIM) to deliver lean and green project outcomes. The resulting framework for BIM-based organizational capabilities development comprising of three hierarchical layers – technology, process and outcomes – is explained.

For this study, BIM has been identified as an enabler and a process for achieving lean and green outcomes on construction projects. Based on a detailed literature review, this paper identifies the organizational capabilities needed by the architecture, engineering and construction organizations to effectively implement BIM on construction projects. The study has been conducted through a sequential mixed-method approach involving semi-structured interviews, focus groups and qualitative comparative analyses.

It was discovered that to attain desired project outcomes, an organization needs to embrace an underlying BIM adoption culture not only within its project teams but also within the organization as a whole. The study also concluded that an integrated approach to BIM usage – connecting it with lean and green initiatives – on construction projects resulted in improved project outcomes, especially ones targeting lean and green aspects of improvements.

The proposed outline for BIM-based organizational capabilities will help the organizations focus on the “human factors” along with the technical factors while striving for successful usage within their organizations.

Using the organizational capabilities matrix, this paper highlights the importance of technical and social skill sets of an individual employee and their role in developing the organizational capabilities to gain the desired lean and green outcomes.

Sustainable construction practices are strongly correlated with a profitable and competitive construction industry, improved client satisfaction and efficient use of resources. However, due consideration is not being given to sustainable construction practices in Nigeria. Therefore, this study aims to identify the unsustainable construction practices on construction sites, the barriers to sustainable construction and possible strategies to improve sustainable construction in Nigeria.

A questionnaire survey of 50 construction sites was conducted with construction professionals on the sites as the specific target, out of which only 43 construction sites have at least a construction professional present at the site. Forty-three filled questionnaires from the respondents were used for descriptive (mean score, standard deviation and charts) and inferential analysis (t-test and Kruskal–Wallis) in this study.

The study shows that a large percentage (75%) of construction professionals in Nigeria are aware of sustainable construction. The descriptive and inferential analysis showed a disparity in the ranking of the 12 unsustainable practices, 14 barriers and 11 strategies among the respondents. Five unsustainable practices (“negative externalities”, “excess energy”, “unsustainable technologies”, “non-management of health and safety of workers” and “material waste”), six barriers to sustainable construction (“absence of historical data and exemplary projects on which construction professionals can build and learn from”, “lack of professional to handle the task”, “poverty and low urban investment”, “lack of urban and construction policy”, “lack of awareness” and “lack of technical know-how”) and three strategies to improve sustainable construction practices in Nigeria (“cooperation, partnership and participation”, “protection of biodiversity and conservation of natural resources” and “sustainability assessment system”) were found to be significant.

The study offers significant insights into the construction industry unsustainable practices, barriers to sustainable construction, as well as strategies for improving sustainable construction practices. These insights can be applied to other developing countries with an emphasis on geographical differences.

To the best of the authors’ knowledge, this is one of the recent studies in Nigeria that explored the context of sustainable construction in the construction industry by providing insights into the unsustainable construction practices, barriers and strategies to improve sustainable construction in Nigeria.

The purpose of this paper is to investigate sustainability efforts in the managerial processes of design, consulting, construction, and facility management firms and to identify the differences between these parties.

A questionnaire survey was administered to design, consulting, construction, and facility management firms in the USA to seek information about the state of sustainability efforts in these firms relative to strategic planning, marketing, business management, financial management, organizational structure, and people management. χ² tests were performed on the data collected to determine if statistically significant differences exist between the project participants relative to sustainability efforts.

Sustainability efforts are related to a firm’s strategic positioning, reputation and experience, and hiring/employment policies, while profit margins are not higher in sustainable projects compared to traditional projects. Statistically significant differences were detected in three of the six items investigated, indicating conflicting interests among the parties.

The study’s limitation is that it is limited to sustainability efforts in the USA.

It is concluded that sustainability demands have changed the nature of design, construction, and operation of buildings in ways that deserve special attention on the part of all parties involved.

The firms that participate in building construction projects need to adopt management practices that accommodate sustainable building design, construction, and operation in order to remain competitive in a market where demand for environmental sustainability has grown significantly in recent years.

The construction industry is known for its complexity, poor performance and impact on the environment. This study investigates the applicability of lean techniques and processes on improving sustainability in construction projects. A total of ten key lean construction (LC) tools are analyzed for impact on 15 sustainability categories and 78 subcategories. Results are summarized for usability across the three sustainability pillars.

A systematic literature review (SLR) of articles published over the last 10 years (2014–2023) on lean and sustainable construction is conducted involving planning, identifying, screening, analyzing and reporting phases. Selected 41 articles are reviewed in detail. For reporting, the applicability of LC tools is critically analyzed and ranked according to impact on sustainability over two project stages.

Literature suggests that the impact of LC on economic waste reduction or social impact is likely to have an impact on environmental sustainability as well. Overall, the top LC tools for improving sustainability in construction include value stream mapping (VSM), just-in-time (JIT) and 5S. The applicability of the LC tools is more prevalent in the “construction phase” of construction projects than the “planning and design” phase.

This study analyzed ten lean tools through SLR and evaluated their impact on construction sustainability. By assessing the challenges and benefits associated with LC tools, the outcomes of the study support the adoption of LC by stakeholders. The paper also proposed a practical implementation strategy for LC tools to enhance sustainable construction.

Achieving sustainable construction is immensely challenging in developing economies due to their inadequate technical support system(s) (TSS). Hence, this article develops a TSS framework for sustainable construction indicators for Zimbabwe, a developing country.

A post-positivist philosophical stance and deductive reasoning were adopted to test pertinent theory. Construction professionals in consultancy, construction companies, government bodies and academic institutions participated in an online questionnaire survey. Primary data was analysed using a reliability test, Shapiro Wilks test, Kruskal–Wallis H test, mean score ranking, normalisation value, factor analysis and fuzzy synthetic evaluation (FSE).

FSE revealed a framework with six critical technical support subgroups, in order of importance viz: innovation for construction sustainability; adequate sustainability expenditure and skills training support; adequate project economic assessment and governance support; adequate circularity and environmental technical support; climate change literacy and supplier assessment support; and adequate decent work support. Existing sustainable construction initiatives can be buttressed by strengthening the six identified TSS through related policy initiatives.

The framework developed constitutes an innovative TSS for Zimbabwe to achieve sustainable construction.
