Critical drivers (CDs) of value management adoption in the Nigerian construction industry

Abstract

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.

Critical success factors for digital partnering of construction organisations – a Delphi study

“…Of these three, the deviation technique is the most used, followed by Kendall's coefficient of concordance. However, studies combining these approaches have also emerged in recent times (Ojo and Ogunsemi, 2019). Over time, the interquartile deviation (IQD) along with the median has been suggested by several studies as the most reliable deviation approach towards attaining consensus (Aigbavboa, 2013; Tengan and Aigbavboa, 2018; Hasson et al , 2000; Raskin, 1994).…”

“…It has earlier been suggested that the chi-square should be adopted when the number of variables to be evaluated is larger than seven (Siegel and Castellan, 1988) as in the case of this current study, and consensus is termed as achieved when computed chi-square value is larger than the critical chi-square value derived (Tymvios and Gambatese, 2016). In a bid to achieve genuine consensus, this study followed the path of Ojo and Ogunsemi (2019) by combining the IQD, Kendall's W and X 2 technique. The Statistical Package for Social Sciences was used as a tool to achieve these analyses.…”

Mitigating Strategies of Threats to Quantity Surveying Profession in The Nigerian Construction Industry

“…For instance, Oke and Aigbavboa (2017) revealed that since the introduction of VM into Nigeria in the 1990s, the application of VM on construction projects in the Nigerian construction industry remain minimal (Oke and Ogunsemi, 2013). Considering the year of VM introduction into the Nigerian construction industry, Ojo and Ogunsemi (2019) opined that VM ought to have been fully embraced into the Nigerian construction process. This shows the drag in the level of improving the services and skills of quantity surveyors in Nigeria.…”

Critical Barriers to Environmental Management System Implementation in the Nigerian Construction Industry

“…The SDs of most of the barriers in this study are approximately 1.00, except for "Negative attitude of employee (B14)" and "Time consuming for improving environmental performance (B20)" with SD of 1.57 and 1.69 respectively. This implies that the variability of the dataset of this study based on the opinions of the respondents is minimal (Oke and Aghimien, 2018;Ojo and Ogunsemi, 2019). Thus, in descriptive terms, the 20 barriers could be termed significant barriers to the implementation of EMS in the NCI.…”
