Waste has been a major challenge in the construction industry. Lean concepts have been adopted in developed nations to overcome waste. However, developing countries are still faced with the challenge due to a lack of strategies for effective lean knowledge by construction practitioners. The purpose of this research is to identify the strategies for lean knowledge in the future Nigerian construction industry.

This was achieved through a case study of a Nigerian university. Assignments and questionnaires were the two instruments used for data collection in the study. Content analysis was adopted to analyse the data obtained from the assignments, while statistical tools such as correlation and ANOVA analysis were used to analyse the questionnaire data.

The findings of the study showed that the introduction of lean theory into students’ academic curriculum, lean practical classes and collaboration between universities, industry and lean construction institutes are some of the critical strategies for adequate lean knowledge in the future Nigerian construction industry.

The study is case-based and focused on a single university. The study did not also put clients’ level of lean knowledge as well as future required acquaintance into consideration.

This study is important as it will enable students to have an adequate understanding of the concept of lean construction right from a higher institution level. This study will enable students to put the knowledge into practice in the construction industry, hence eliminating waste or NVAAs in future construction projects.

The findings of the study could enhance concerted efforts by universities, lean construction institutes and the construction industry towards an intentional and systematic delivery of lean knowledge that will reduce waste in future Nigerian construction projects. Further studies should be carried out to identify the success factors required by clients for effective lean knowledge in construction projects.

Non-value adding activities or wastes in the lean term have been the major challenge of the construction industry. Numerous studies have been conducted to investigate how such wastes can be reduced so as to improve the performance of the construction industry. However, the aspect of bricks production process (BPP) has not been extensively covered. Therefore, the purpose of this paper is to investigate the application of lean manufacturing concepts in BPP with a view to identifying the various wastes in the practice, the causes of these wastes and how such wastes can be reduced.

Mixed methods research design was adopted by the researchers where literature review was first conducted to establish the fundamental theories and practice standards of lean manufacturing process. Thereafter, a phenomenological study was carried out in a Shelter Clay and Brick Factory located in Minna, Niger State, Nigeria. The data obtained in the phenomenological study were analyzed through content analysis. These data served as the basis for the validation survey that subsequently followed the phenomenological study.

The findings in the study show that poor or inadequate supervision is the main factor responsible for wastes such as excessive drying of bricks, overheating of bricks and re-glazing of bricks in Nigerian BPP.

The study focused on the various wastes in Nigerian BPP. It also focused on the various lean tools/techniques that can be adopted to reduce the wastes. Aspects such as the percentage of the wastes and their cost implication on the factory were not covered during the study and could be further investigated by prospective researchers.

The study provides knowledge on how lean thinking can be adopted to reduce wastes in BPP. Such knowledge may be beneficial to the present and prospective bricks producers. This implies that the proposed framework in the study allows producers of bricks to identify gaps in their implementation efforts, focus attention on areas that may require improvements, and access the benefits of lean approach in their factory products. The proposed framework may also be beneficial to the academics.

This paper first gain originality in the study context to propose for a lean framework that can be adopted to reduce wastes in BPP. Furthermore, the paper has not been previously published and all the information obtained from other sources are duly referenced.

This study aims to avail architects with the potentials of knowledge management (KM) principles towards an optimal and effective procedural mechanism for the choice of building materials during design and construction processes.

In all, 202 questionnaire forms were distributed in a survey. They were administered to practicing architects and Architectural firms in Nigeria. Thereafter, ANOVA, regression analysis and exploratory factor analysis with reliability and Cronbach’s alpha coefficient of 0.861 identified KM principles in specification writing for architects.

These findings show that the building material selection procedure can be optimized with efficient and conscious consideration of KM principles imbibed by architects in tune with global trends. The study serves as a guide to architects and other stakeholders on the effect of KM principles in deepening reflectiveness of the surpassing role of effective KM in specification writing in the construction industry.

This is perhaps the first empirical research that sought to understudy knowledge sharing strategies in architectural firms within the context of the study location Nigeria. The value of the research lies in optimization of architects’ building materials’ specification strategy through KM principles.
