Empirical evidence of compliance or otherwise with procurement laws especially in developing nations is limited despite its importance in ensuring quality project delivery. This research assessed compliance with the procurement law in the local government setting of a developing nation, challenges to compliance and workable solutions. A total of 108 copies of a carefully structured questionnaire was administered to individuals concerned with contract administration in the local governments in the study area and 87 were considered good enough for analysis. Data analysis was done using cross tabulation, chi-square, mean score and percentile. Among other findings, the study revealed that there is partial compliance with the procurement clauses in the local governments. The study also revealed that significant relationship exists between knowledge of the procurement act, owning a copy of the act and compliance with the act. These findings of this study will be useful for construction and public procurement administrators as an evidence of the need for a multifaceted action towards strengthening compliance.

Purpose This paper aims to assess the drivers of value management (VM) in the Nigerian construction industry with a view to identify the critical ones through Delphi study. Design/methodology/approach A team of 15 carefully selected experts in VM were engaged in two rounds of Delphi survey, and the responses of the survey were analyzed with descriptive statistics (mean, standard deviation and mode). Kendall’s coefficient of concordance test and Chi-square (χ2) test were also used to test the level of consensus amongst the respondents at the two rounds of the survey to draw inference. Interrater agreement analysis and significant level analysis were further used to determine the criticality of critical drivers. Findings The critical drivers to VM adoption are adequate understanding of the benefits of VM, higher/postgraduate programme that teaches VM technique, professional’s previous experience with VM, collaboration of all construction professional bodies in Nigeria and VM training. Originality/value This paper used opinions of VM experts only to achieve the aim of this study as against the common survey method in which respondents who are not knowledgeable in the area of research might fill the questionnaire.

The impact of different hazardous substances of the construction industry being released to the environment is alarming. This constitutes an adverse effect on the quality of life of construction workers and the populace at large. To reduce this menace, Environmental Management System (EMS) was put in place. Meanwhile, the implementation of EMS in the Nigerian construction industry (NCI) is not certain. This study, therefore, investigated the barriers to EMS implementation in the NCI to group them into a smaller form, i.e., fewer numbers. A questionnaire survey was developed and administered to construction professionals in Nigeria using a purposive sampling technique. The retrieved 106 copies of the questionnaires were subjected to both descriptive and inferential statistics such as mean score, standard deviation, analysis of variance test, post hoc test, and exploratory factor analysis. An exploratory factor analysis was conducted three times to identify the critical barriers to EMS implementation in the NCI. The study findings reveal three main categories of barriers affecting EMS implementation, namely; (1) knowledge barrier; (2) process barrier; and(3) culture and management barrier. The study concluded that the three factors indicate the major cardinal barriers that could describe the impediment of EMS in the NCI. It was recommended that the training of construction professionals is important to enhance improvement culture in the NCI.

Quantity surveying (QS) profession had faced numerous challenges in recent decades than when it was first introduced in developing countries. In addition, opportunities via technology advancement to the profession were also perceived as threats. This, therefore, inform the need to investigate the possible mitigating strategies to the threats confronting the profession in the Nigerian construction industry as an attempt to proffer solutions. Therefore, opinions of quantity surveyors in construction firms, consulting firms and government establishments of Lagos State, Nigeria were collected through a survey. The mitigating strategies garnered from extant literature were used to elicit the opinions of the respondents. One hundred and twelve (112) copies of questionnaires were administered, while the retrieved copies were used to analyse with both descriptive and inferential statistics. Mean score and Standard Deviation (SD) were used to rank the opinions of the respondents, and factor analysis was used to group the mitigating strategies into concise form for ease of discussion. The results of the analysis show that the mitigating strategies identified in the study are significant to mitigating the threats in the QS profession. The factor analysis conducted grouped the mitigating strategies into four major groups, namely practice, knowledge, progressive learning and ethics. These groupings were discussed within the context of the study and in relation with previous researches. This study proffers possible solutions to the threats to the QS profession that had been publicised in many studies.

Green supply chain management (GSCM) is an important part of most production organisations in developed countries. Meanwhile, developing countries are yet to fully embrace the concept. This study, therefore, investigated the drivers of GSCM using a close-up approach in a leading manufacturing organisation in Nigeria with sustainability initiatives. One hundred and fty-four questionnaires retrieved from the supply chain management team of the organisation were subjected to descriptive and inferential statistics such as mean score, standard deviation, and factor analysis. Based on the results of the analyses, that the drivers of GSCM in the organisation could be grouped as government-related, organisational-related, and societal-related drivers. The study concluded that synergy of the government, organisations, non-government organisations, and individual is important for achieving green supply chain practices in developing countries. It was recommended that training at all levels is essential to improve the awareness and importance of sustainable production to the environment.
