<p>Previous New Zealand waste management studies have focused on the waste generated from construction activities. However, international research suggests about a third of the overall waste generated originates in the design phase. Internationally, lean design management claims to reduce the waste produced by inefficient design practices. In New Zealand, the literature reveals that the application of lean principles is still in a fledgling state, and even where they are used, waste minimization is not a business priority. This leads to the question: can lean design management be used by construction projects in New Zealand to reduce waste in the design phase? This paper investigates the attitudes, experiences and expectations towards construction waste minimization of a selection of architects using a semi-structured questionnaire. It was found that Wellington-based architects can be broadly classified into 3 categories of lean awareness—high, medium, and low. The medium group, largest in number, comprised architects who identified waste as a problem, but cited post-construction recycling and reuse as their preferred approach to waste minimization. This group notably had 20-25 years of experience in the industry, and related material reuse to residential construction only.</p>

PurposeConstruction 4.0 technology has the capabilities for improving the design, management, operations and decision making of construction projects. Therefore, this study aimed at examining the willingness of construction professionals towards adopting construction 4.0 technologies.Design/methodology/approachThe study adopts a survey design, and construction professionals in South Africa are assessed using a convenience sampling technique through a structured questionnaire. The questionnaire was analysed with SPSS while statistical test like; mean score, t-test and principal component analysis was used to present the data.FindingsThe findings, from the analysis, revealed that the construction professionals are willing to adopt construction 4.0 technologies for construction project. However, the possibility of fully integrating the technologies into the construction industry is low. This is because the major technologies such as; Internet of things, robotics, human-computer interaction and cyber-physical systems that encourage smart construction site are rated as not important by the construction professionals.Practical implicationsIt is believed that the findings emanating from this study will serve as an indicator for investors that are interested in procuring construction 4.0 technologies for the construction industry.Originality/valueThis paper presents a framework for the application of construction 4.0 technologies for the construction industry. It also contributes to the development of digitalising construction industry in South Africa.

Area Of Concern

Construction industry in Malaysia is growing rapidly with high demand due to vast development and urbanization. Therefore, many commercial and residential buildings are being developed. The increasing number of construction projects in Malaysia will indirectly contribute to the increase of construction waste generation. Thus, waste minimization is an important area of concern in the implementation of the construction waste management in the construction industry of Malaysia. Data collection and observations was conducted at three construction sites which adopt different type of method with different type of building and size of project in Klang Valley. The calculation of the construction waste index generated at these sites is adopted from Poon et al., (2001). Result showed that construction method, size of projects (GFA), type of building, storage method system, human error and technical problem can affect the amount of waste index (debris) and amount of wastage level generated at construction sites. Therefore waste index and wastage level can be used as operational an indicator for waste minimization of the construction activities.

Evidence exists for the application of lean management practices in the design process. However, there is no systematic review of this type of practice that links the design management practices to the lean construction principles. There is no tool to assess the level of use of lean design management practices in construction projects either. Therefore, this paper aims to assess the lean management practices that are performed at the design phase of construction projects. The research was divided into a literature review of design management practices; a validation of lean design management practices with a practice–principle relationship, based on an expert survey; the devolvement of a tool (questionnaire) to evaluate the lean design management practices; and an assessment in 64 construction projects (coherence, reliability, correlation, and descriptive analysis). It is concluded that evidence exists for the implementation of 19 lean design management practices. These practices are grouped into three categories: stakeholder management, planning and control, and problem solving and decision making. Additionally, in the assessment of the 64 projects, it can be observed that the lean design management practices are at initial levels of implementations, so there is a significant development gap. This research proposes a tool to assess management practices in the design phase of construction projects; then, the study identifies implementations gaps, it provides benchmarks with other projects, and it improves the design process through a taxonomy of lean design management practices.

Waste disposal has become an issue worldwide and the major cause of this issue is considered to be the construction activities producing wastes. Pakistan being the 6 most populated country in the world is considered to have a huge amount of waste due to the various construction and particularly megaprojects and this amount of construction waste is increasing consistently in the country. Pakistan produces of construction waste per year and is increasing annually by 2%. These increasing wastes and issues associated with these construction wastes lead to a crucial need for improvement of waste management practices in the construction industry of the country through various measures. Despite of the large need for waste minimization research in Pakistan, , deductive approach was used, and quantitative method was selected, the present study has used cross-sectional design. The researcher used a sample of 323 individuals and conducted a questionnaire-based study.
