Purpose Buildability analysis has a potential of improving the outcomes of construction projects. However, the usage of buildability analysis is not well pronounced within the construction sector. This study aims to provide understanding of the concept of buildability analysis with the view to predicting the future stance for buildability analysis. Design/methodology/approach The study adopted a survey research method. Questionnaires were administered to purposively selected group of construction professionals working in Nigeria. A total of 82 questionnaires were administered among the sampled respondents, out of which a total of 51 (62.2%) were adequately filled and returned. The data collected were analysed using descriptive and inferential statistics. Findings The results revealed inability of the designers and constructors to have a common upstanding of the entire construction process, fragmented nature of the construction industry and poor correlation between design and construction as the most essential needs for buildability analysis. On the benefits of buildability analysis, the results showed increase inefficiency, save wasteful efforts and quality improvement as the most significant ones. In addition, the results from the study revealed that there is a statistically significant difference in some of the needs for and benefits of buildability analysis among the survey participants. Originality/value The study identified three future stances for buildability analysis to include building unity, efficient and effective construction and high competition. Framework for buildability analysis was developed aimed at providing guidance to professionals in achieving enhanced project production information. The findings provide in-depth insight of the needs for and benefits of buildability analysis that can inform professionals in the construction industry to adopt buildability analysis programme as a lasting solution to most design challenges and buildability problems confronting the sector.

Growing demands for building projects result from economic development. The building industry is dynamic and multifaceted. Efficient and effective practice of building production management (BPM) is required to successfully execute projects and achieve project goals upon completion as well as functionality aims for the lifespan of a building. This research aims to determine factors that influence the BPM practice in the Nigerian construction industry, particularly; during the project execution phase. A cross-sectional survey used; a questionnaire to identify 73 factors, which were grouped into 12 categories and assessed. A purposive sampling technique was used to identify 20 construction organisations specialising in building production management in Lagos, Nigeria. 114 questionnaires were distributed to the pool of stakeholders, which included 31 clients, 34 consultants and 49 contractors of current and past building production projects carried out by the selected firms in Lagos. The research used a selection of statistical tools for SPSS v.23, including the chi-square test, the Kruskal-Wallis test and Kendall's coefficient of concordance. The obtained result revealed the factors that mostly influence the BPM practice namely, architectural drawings, the construction programme document, the work breakdown structure, the adequacy of communication and coordination between the parties, the adequacy of raw materials and equipment, the availability of the competent team, the implementation of the safety management system, regular maintenance of project equipment, clear and timely inspections, the availability of funds as planned throughout the project duration, the availability of skilled personnel, and the aesthetics of the completed work. The research resulted in the development of the BPM implementation framework and recommendations for the improvement of the BPM practice in Nigeria.

Studies have shown that adoption of sustainable construction practice would result in a substantial reduction in the greenhouse emissions from the construction industry. Evolving a sustainable development practice is an emergent concern for the construction industry in both developing and developed countries. Sustainable construction is concerned with site planning and design, community, indoor air quality, energy, materials, water, commissioning and marketability for the benefit of mankind. This requires enormous efforts from all the stakeholders in the industry. Sustainable construction efforts in the Nigerian construction industry have been ineffective as a result of a number of barriers that prevent a smooth transition to sustainable construction practice in the country. The aim of this study is to assess the potential barriers that hinder effective adoption of sustainable construction practice in the Nigerian Construction Industry, with a view to exploring how these barriers can be overcome and thereby achieving sustainable construction in the country. A cross-sectional questionnaire was adopted for the survey. Purposive sampling technique was used to elicit 105 copies of questionnaires from various construction professionals based in Lagos state, Nigeria. Data collected were analysed using frequency, percentage, mean, relative importance index and ranking. The results revealed that key barriers to sustainable construction in the Nigerian Construction Industry are poor government support for sustainable construction, lack of relevant laws and regulations to drive sustainable construction, lack of demand for sustainable construction from clients, low level of awareness of sustainable construction and fear of the cost of adopting sustainable construction. Based on the findings from this study, it was recommended that government should assume a greater role in the popularisation and application of sustainable strategy. The barriers identified and the suggestions made to minimize barriers to the adoption of sustainable construction in Nigeria should offer an enabling environment for stakeholders in construction sector to smoothly adopt sustainable construction for the benefit of humanity.   Keywords: adoption, barriers, construction industry, Nigeria, sustainable construction

Purpose Human resource contributes significantly to the outcome of construction projects. In recent years, apprenticeship programs are being implemented to train young people to address shortage of skills workers and ageing workforce problem. This study aims to understand the factors influencing career decisions among apprentices in the construction sector. Design/methodology/approach A qualitative research approach was used to address the objectives of the study. Forty semi-structured interviews were conducted to gain insights into the reason why young people decide to participate in construction craftsperson apprenticeship in Nigeria. Findings The study reveals that “interest and passion”, “role model”, “macroeconomic environment and government policies”, “spirit of entrepreneurship”, “formal, informal and non-formal education” and “family socioeconomic status” are the factors influencing career decisions among construction craftspeople. Originality/value The study provides fresh insights that can be used to develop strategies for attracting and increasing the number of young people that sign up for construction craftspeople apprenticeships. The apprentice training programmes are essential for addressing labour shortage, which is one of the factors affecting the performance of construction projects.

Purpose Improving buildability of building designs with the aid of buildability assessment is essential because of the effect of designs on construction. Despite the plethora of research into buildability reported over the years, a review of the literature shown a dearth of research into the factors supporting the implementation of buildability assessment. Because buildability assessment has been confirmed to be highly beneficial to construction business, this study aims to investigate the factors supporting the implementation of buildability assessment as a tool for buildability improvement using Nigeria as a representative case. Design/methodology/approach Survey research method was adopted for the study. Questionnaires were administered to a purposively selected group of architects, engineers, builders and quantity surveyors involved in construction project delivery within client, consulting and contracting organisations in Nigeria. A total of 368 questionnaires were distributed among the sampled participants, out of which, a total of 219 representing 60% were sufficiently filled and returned. Data collected were analysed using inferential and descriptive statistics. Findings The results revealed owner’s commitment, clients’ awareness of the benefits of conducting buildability assessment on building design, unity amongst different professionals in the construction industry, designers consider buildability important, adequate coordination amongst different design disciplines, adequate channel for co-ordination and communication between designers and constructors at the design stage and adequate support from the government as the top most seven factors supporting buildability assessment implementation in construction sector of Nigeria. Secondly, the results from the research revealed that there is no statistically significant difference in factors supporting buildability assessment implementation in construction between clients and consulting and contracting construction organisations in Nigeria. Originality/value The findings provide in-depth insight of the factors supporting the implementation of buildability assessment in construction that can help principal stakeholders in construction to facilitate development of strategies required in supporting the adoption and implementation of buildability assessment tool for buildability improvement.
