Building information modelling (BIM) adoption is vital to the productivity and competitive nature of the construction sector. However, BIM adoptions have not been generally embraced by many architecture, engineering and construction (AEC) firms, particularly in developing countries. Moreover, studies that investigate the important drivers to BIM adoptions among construction professionals through quantitative approach are limited. The purpose of this study is to address the aforementioned gap.

This study involves a literature review, a pilot study and a questionnaire survey. The primary data were carried out using structured questionnaires distributed to four different BIM adopter AEC firms. These comprised architectural firms, facility management firms, quantity surveying firms and structural engineering firms in Lagos, Nigeria. Data obtained were analysed using mean score, standard deviation, Kruskal–Wallis test and factor analysis.

The study identified 23 drivers to BIM adoption, and the relative importance of the identified drivers was gauged from each selected BIM adopter AEC firm category. The result of the Kruskal–Wallis test showed that there is no statistically significant difference in the perceptions of the four selected AEC firms in the mean ranking of the identified 23 drivers to BIM adoption. The findings from factor analysis categorized the identified drivers into two major factors to include cost and time savings, improved communication, and BIM awareness and government supports.

The study empirically identifies important drivers to BIM adoption that will be useful for construction stakeholders to formulate strategies to adopt the full implementation of BIM in the AEC firms of Nigeria and other developing countries. Also, this study is important as it identifies, analyses and compares the drivers to BIM adoptions from four different AEC firms, thereby providing robust and more reliable findings.

The study findings will provide information to policymakers and construction stakeholders to make policy recommendations that are capable of positively influencing the widespread adoption of BIM in AEC firms in particular and the construction industry at large. This study is important because the studies that comparatively and empirically analyzed BIM drivers in AEC firms are rare, particularly in developing countries. Hence, this study could be used to benchmark future studies in developing countries.

This study aims to investigate two public private partnership (PPP) road projects in Nigeria for exploring factors that can motivate end-user stakeholders for contributing towards sustaining a PPP project in the long-term.

Using a case study methodology approach, this study adopts two-way data collection strategies via in-depth interviews with PPP experts and end-user stakeholders in Nigeria host communities and a questionnaire survey to relevant stakeholders.

The study identifies an eight-factor structure indicating critical success factors for ensuring end-user stakeholders support PPP projects on a long-term basis in their host communities.

Results of the study have huge implications for policymakers and project companies by encouraging the early integration of far-sighted measures that will promote long-term support and sustainability for PPP projects amongst the end-user stakeholders.

The purpose of this paper is to investigate the food security status of 150 households in Osun state of Nigeria. The study area was chosen because relatively little energy consumption data are available concerning this geographical location.

The study used both primary and secondary data. The suitable households sample was chosen by multi-stage random sampling technique. The methodology employed to group the households into either food secure or food insecure is by comparing daily per capita calorie consumption by each household with the threshold daily per capita calorie requirement of 2,710 kcal/day/adult equivalent. This method has proven to be efficient in measuring food security at household level.

The results of the study reveal that majority of the households surveyed are food insecure that is their daily per capita calorie intake falls below the recommended daily per capita calorie requirement. The food insecure households constitute 54 per cent, surplus index of 0.36 per cent and food insecurity gap of 0.0038.

The greatest limitation to this study is the inability to collect data on the distribution of income, budget share on foods and socio-economic characteristics of the households to determine how their food security status is influenced due to impediments such as time, limited resources to collect a complete dataset used for the study. Also, recalling accurately the foods eaten in the last 24-hour was difficult for some of the household heads especially the aged ones and precise measurement of foods portion were also not accurate in some cases.

The findings of the study will help the stakeholders in food sector in policy formulations and also serve as reference for other researchers who will work on similar topic.

The revelation that majority of the households are lacking in calorie intake will provide guidance for stakeholders in food sector to put in place efforts that will improve balance between food production and accessibility.

The study used original data collected directly from the households for the study using structured questionnaires and the reference materials from secondary sources are appropriately cited. Also, it is worthy to note that not many studies have been carried out in the study area on food security especially in the rural areas.

The purpose of this study is to determine the level of job satisfaction, turnover intentions and performance of Nigerian polytechnic lecturers with PhDs and to empirically examine the relationship between them.

This study adopted a descriptive correlational research design. Thus, an online self-reported questionnaire was used to gather primary data from a purposively selected sample of 167 Nigerian polytechnic lecturers with PhDs. Descriptive statistics and PLS-SEM were employed to analyse the data collected.

Descriptive results showed a low level of job satisfaction, high level of turnover intention and moderate level of performance of Nigerian polytechnic lecturers with PhDs. The structural model indicated a significantly positive link between job satisfaction and performance of Nigerian polytechnic lecturers with PhDs. Additionally, further analysis showed significantly negative links between job satisfaction and turnover intentions and between turnover intentions and performance of Nigerian polytechnic lecturers with PhDs.

There is a paucity of empirical studies on the impact of turnover intention on employee performance, particularly in the Nigerian context. This study provides empirical evidence of the negative impact of turnover intention on lecturer performance in the Nigerian context. Importantly, the findings of this study provide insights into the fundamental issues, which underlie the brain drain of lecturers in higher education institutions, especially in developing countries.

Challenges to energy access in Nigeria have resulted in the widespread use of fossil fuel generating sets (generators) despite its renewable energy (RE) potential. Given the climate crisis, combined with the country's rapid population growth and expected rise in energy and building demand, transitioning to low-carbon electricity using REs like solar photovoltaic (PV) presents opportunities beyond securing its energy future. While PV use is growing in Nigeria, this is focused on the residential sector despite the identification of the commercial sector as a high energy consumer and a key platform for its integration. In line with this, this research aims to investigates the challenges to energy transitioning from generators to solar PV in commercial buildings.

A qualitative approach in line with grounded theory was adopted using in-depth face-to-face interviews with industry experts.

Two distinct but interrelated categories emerged: being held captive and being a saviour that represented a duality of systems, and/or processes formed the core category “Hostage Syndrome”. The core category (theory) was generated based on the explanations and expressions by participants about their concerns, interests, and the conditions under which they operate. The findings reveal the value attributed to generators beyond an operational role and the adjustments or mechanisms adopted by building professionals during their practice. It suggests a sphere of influence beyond the obvious financial and/or institutional aspects, as determining factors to what is viewed as sustainable which will be key to transitioning to REs.

This paper provides new and in-depth insight into understanding the conditions under which building professionals operate associated with their interpretations of “being sustainable”. The study highlights the need to consider psychological and cultural factors in the development of interventions, strategies and/or policies to support RE transition, particularly towards achieving a sustainable construction industry.
