Carbon estimating plays a vital role in the construction industry. The current focus on introducing zero-carbon construction projects reduces operational carbon, at the expense of Embodied Carbon (EC). However, it is important to reduce overall net carbon emissions. There are various methods to estimate carbon, but the accuracy of these estimates is questionable. This paper reviews a novel methodology, the Supply Chain based Embodied carbon Estimating Method (SCEEM), which was introduced recently to accurately estimate EC in construction supply chains. SCEEM is compared against existing EC estimating methods (Blackbook and eToolLCD) using a case study approach. It is also supplemented with a comprehensive literature review of existing EC methods. The EC values calculated using Blackbook and eToolLCD were mostly higher than SCEEM. Since SCEEM uses actual site data and considers first principles-based value addition method to estimate EC, it is considered accurate. The cross-case analysis revealed that SCEEM provided consistent results. Hence, SCEEM is recommended to accurately estimate EC of any type of project.

Purpose – The purpose of this paper is to understand the nature and extent of current practice of construction supply chain management (CSCM) in the New Zealand (NZ) construction industry; consequently, to examine the challenges and issues that the industry is confronted in implementing an efficient CSCM. The construction industry, which contributes around 5 per cent to gross domestic product, is a vitally important industry in NZ. With over 50,000 businesses, the construction industry is the third largest industry by business count in NZ’s economy (Statistics New Zealand, 2009). Although it is widely accepted that productivity can be improved by adoption of effective supply chain management (SCM), no studies have investigated this at the tactical level in the NZ context. Design/methodology/approach – A case study approach is used for probing SCM practice on a NZ$75-million commercial project located in Auckland Central Business District. The supply chain network of the principal ground works and superstructure construction stages was studied. Findings – The key findings of the case study suggest that the flow of materials remains the main focus of CSCM practice. It was found that essential skills training for CSCM was extremely limited and largely ill-defined in terms of its nature and content. Finally, it was identified that as the NZ construction industry moves towards a significantly more collaborative framework, the efficacy of CSCM operations is expected to substantially improve. However, this last point did not negate the requirement to expand and improve skills training in CSCM. Originality/value – The results of the case study present that our best industry proponents are inadequate in their knowledge of CSCM as a result of education and training. This is a key issue that needs to be addressed through education at all levels. Similarly, they have virtually nil capability with logistics and the efficiency of transportation as a result of standard contractual costing procedures. Until the SCM/logistics knowledge gap is recognised and addressed, the improvements in logistics and, therefore, SCM will not occur in the NZ construction industry. That said, the findings related to partnering and collaborative thinking in NZ are encouraging. NZ has these elements largely in place already and a willingness to engage, particularly in alliances, in the future. It remains to be seen whether there will be sufficient energy expended in NZ by the leading players to create effective partnering and alliancing through improving SCM and logistics competencies.

Knowledge management has largely been considered from the perspective of internal generation. It is posed that external provision will increase due to the diversity of problems and scarce resources, the arising issues being explored through a case study. The aim is to explore this process for construction projects. It will be shown that the successful delivery of knowledge services for the construction industry depends upon the way in which the provider conducts its marketing and the operation of gatekeepers in the project organisation. These issues are explored in relation to the main concepts and theories, applying and evaluating these through the case study approach.

The spread of COVID-19 has obstructed construction projects worldwide owing to disruptions in supply chain, restriction on the combine work and legislative enforcements. Construction projects from developing economies are more susceptible to these challenges. The aim of this research is to identify factors caused by COVID-19 impacting progress of construction projects and review tools to lessen its negative impact. Multistep methodology is adopted using semi-structured interviews with construction experts to identify factors affected the progress during COVID-19; and data collection from professionals to quantify the significance of each identified factor; Cronbach’s alpha for reliability and multiple regression to assess the effect of COVID-19 on progress of construction projects. The findings show that COVID-19 has left severe issues at the operational and financial levels. The remedies use to correct these issues will help policymakers from construction industry to improve existing strategic plans and develop new policies to manage the issues caused by COVID-19.

The number of activities in construction projects is increasing where the pace of development follows the development of rising funds with shorter time constraints. As a result, businesses have reacted by allocating people to numerous teams simultaneously. The purpose of this study is to explore the implementation of multiple team membership and the performance of workers as individuals and teams in the construction industry, especially in DKI Jakarta. In addition, this study also explores the appropriate approach to use so that projects carried out using MTM can run smoothly. This research employed qualitative research with a case study approach also used a structured interview method with purposive sampling of 20 workers. The location is in the construction industry in DKI Jakarta. It was found that the implementation of MTM on employees with higher positions provided more benefits than employees with lower positions. The benefits for higher employees are getting paid more, more insight, more relationships, and bids for future projects. Meanwhile, employees in lower positions only get broader insights. In addition, it was also found that the appropriate approach to use so that MTM projects can run smoothly is to improve multitasking abilities and manage schedules and strategies.

The choice of materials is crucial in responding to the increasing embodied carbon (EC) impacts of buildings. Building professionals involved in material selection for construction projects have a vital role to play in this regard. This paper aimed to explore the extent to which building professionals in Sri Lanka considered EC as a material selection criterion. A questionnaire survey was conducted among a sample of building professionals in Sri Lanka. The results indicated that the consideration of EC as a material selection criterion remained low among key professionals, such as architects, engineers, and sustainability managers, despite their reasonable influencing powers and knowledge of EC. Those respondents who had considered EC as a selection criterion said they had been primarily driven by green building rating systems and previous experience. Those respondents who had not considered EC during material selection commonly reported that they had been prevented from doing so by the lack of regulations and the lack of alternative low carbon materials. Respondents believed that the involvement of actors, such as the government, professional bodies, environmental organizations, activist groups, and the public, may be significant in promoting the greater consideration of EC during material selection.

This study investigates a special kind of corporate ventures, so called spin-along ventures, and their motivations to internationalise early. Insights are built from a multiple case study approach, investigating the spin-along program of Telekom Innovation Laboratories (T-Labs). Our results show that early internationalisation can avoid or reduce challenges that spin-alongs face when entering the domestic market. Four major motivations for early internationalisation could be identified: (1) avoid termination based on the parent's perceived threat of cannibalisation of existing products, (2) enable a venture's collaboration with competitors, (3) overcome restrictions of parental assets in the domestic market, and (4) address markets that offer greater chances for success than the domestic market does. Based on our findings we derive concrete implications for practitioners and academics in the field of innovation management.

Big data applications consist of i) data collection using big data sources, ii) storing and processing the data, and iii) analysing data to gain insights for creating organisational benefit. The influx of digital technologies and digitization in the construction process includes big data as one newly emerging digital technology adopted in the construction industry. Big data application is in a nascent stage in construction, and there is a need to understand the tangible benefit(s) that big data can offer the construction industry. This study explores the benefits of big data in the construction industry. Using a qualitative case study design, construction professionals in an Australian Construction firm were interviewed. The research highlights that the benefits of big data include reduction of litigation amongst projects stakeholders, enablement of near to real-time communication, and facilitation of effective subcontractor selection. By implication, on a broader scale, these benefits can improve contract management, procurement, and management of construction projects. This study contributes to an ongoing discourse on big data application, and more generally, digitization in the construction industry.
