This paper examined the state of major cultural properties in Ile-Ife -a traditional settlement known in history as the cradle of the Yoruba civilisation. This was to unfold the level of deterioration, identify the causes of decay and suggest appropriate maintenance solutions. In order to carry out this assessment, selected cultural properties such as the Museum, Ooni ' s palace and shrines such as Ile-Oduduwa, Ifa Temple, Oke-Mogun and Opa Oranmiyan were examined through physical surveys. The analysis was carried out on data procured through the administration of a set of questionnaires. Findings revealed that these cultural properties were in a state of neglect and had no source of funds for their maintenance. The paper concluded that the nonchalant attitude of the custodians of these cultural properties to maintenance contributed to their inability to source for funds, thus allowing the observed decay.
The study appraised the degree of necessity and usage of material management methods adopted by small-scale construction firms in Abuja and Lagos State, Nigeria. It identified and examined the factors affecting material management practices, and assessed material management-related factors influencing cost variance. Eighty (80) structured questionnaires was administered on sites supervisor/manager through purposive sampling. Data obtained were analyzed using frequency, percentages, Mean score and relative severity index. The study revealed the most important material management method as site planning and organization (4.95), while employment of security (4.88) was often adopted for effective material management. The study found the most severe factors affecting material management as poor site organization, non-availability of material on sites, material not delivered as per schedule with severity index of (0.958), (0.948) and (0.928) respectively. Inadequate storage facilities (3.69), damaged materials (3.65), Loss of material (3.54), were found as material management factors most influencing cost variance. The study therefore recommends that; proper site organization should be carried out on construction site; materials should be made available on-site with required quantities and delivered as at when due with adequate stacking and storage facilities. More so, there should be adequate storage facilities on construction sites, material damage/ loss of material should be reduced to the barest minimum. The service of a good estimator should be engaged by the firms to mitigate against inaccurate/poor estimation of materials.
Purpose This study aims to undertake a contextual analysis of project-level building information modelling (BIM) adoption in Nigeria and demonstrate how BIM is applied across different projects in Nigeria. Design/methodology/approach This research generates contextual and holistic understandings of multiple project-level cases of BIM adoption through an interpretive paradigm guided by relativist ontology and subjectivist epistemology. Two models of project-level BIM adoption (ten-factor theory of BIM adoption and strategic-contingent model of BIM adoption) were merged to formulate the BIM adoption assessment scale (BIM-AAS). A qualitative-oriented case study protocol was developed to extract valid and reliable data from external and internal project data based on BIM-AAS features. The extracted data were analysed using the pattern-matching technique and cross-case analysis. Findings The results indicate that there was substantial use of BIM tools and technologies in the projects. All the projects adopted collaborative procurement and team and developed integrated building information models. The use of BIM tools, technologies and processes in the projects was found to be above average. The complexities and expectations levels of the projects compliment the nature of BIM adoption in the projects. Research limitations/implications The BIM-AAS adopted in this research is an excellent example of a project-level BIM adoption analytical tool. It can be assumed in future research. Also, this research contributes to the theory that the level of project complexity and expectations must align with the level of BIM adoption in projects. The study’s findings ratify BIM tools, technologies and processes as the elements of project-level BIM adoption. Practical implications This research substantiates the actual nature and structure of BIM adoption in Nigeria, thereby simplifying the development of initiatives towards BIM adoption in projects and determining the appropriate strategies for BIM implementation and innovation in the Nigerian construction industry. The most important initiative that the Nigerian government can make to drive BIM implementation is the automating of code checking for building rules and regulations in Nigeria. Originality/value Previous studies have only reported cases of project-level BIM adoption using surveys and without a standardised project-level BIM adoption model to guide the analysis. This study is the first to formulate and use BIM adoption models for a uniform, critical and contextual analysis of project-level BIM adoption.
PurposeBecause BIM adoption is still afflicted by various types of hurdles, a complete BIM implementation model is required to provide the necessary methods for driving BIM adoption. As a result, this study looked into the parts of the BIM implementation model that had the most impact on increasing the percentage of BIM adoption in South Africa.Design/methodology/approachThis study developed a four-wheel model of BIM implementation based on implementation process theory, which includes BIM inspiration, BIM capacity development, BIM use and BIM commitment. To assess BIM capacity development, two sub-constructs (BIM learning process and BIM learning methodologies) were used. Two sub-constructs were used to assess BIM utilisation (efficient BIM application and effective BIM application). The sub-constructs employed to quantify BIM motivation were organisational competitiveness, societal conformity and contractual obligations. Incentives, investments and obligations were used to assess BIM commitment. The model was validated using four assumptions and maximum likelihood estimation – structural equation modelling (MLE-SEM).FindingsThe MLE-SEM results demonstrated unequivocally that all of the constructions are critical components of the BIM deployment paradigm in the South African construction industry. BIM motivation, as characterised by organisational competitiveness and social compliance, has the greatest impact. The findings on BIM motivation also revealed that the desire for technological sophistication, competitiveness and social acceptance by clients are encouraging construction organisations and professionals to embrace BIM adoption.Research limitations/implicationsThis study's findings have contributed to the increasing body of literature on BIM deployment. The study has significant implications for achieving BIM implementation in underdeveloped nations where BIM deployment is either non-existent or in its early stages. The theoretical component of the study serves as the foundation for further analysis of BIM deployment.Practical implicationsThis research is important for identifying BIM goals, developing a BIM implementation framework, allocating resources for BIM implementation and defining key performance indicators for BIM implementation. The BIM implementation aspects outlined in this study will be effective in lowering BIM adoption hurdles.Originality/valueThis study makes a unique contribution to BIM research by providing theoretical and empirical analysis into the elements of the BIM implementation model in a developing country. The study offers an excellent opportunity to further our understanding of BIM application in underdeveloped nations.
The study assessed the perceptions of stakeholders on factors causing sports facilities defects in selected universities established between 1957 and 1962 in South-West Nigeria by examining the strength of the identified factors responsible for sports facilities’ defects in the selected universities. Data were collected using a structured questionnaire which was administered on sports men and women and maintenance personnel. The study incorporated all the fifteen sports featured at the Nigeria University Games Association (NUGA) competitions. Three federal universities were purposively selected because these have facilities for all the fifteen sports and have hosted national and international sporting events. Data obtained were analysed using frequency distribution, percentages, mean response analysis and factor analysis. Using the mean response analysis, the result showed that the most severe factors responsible for sports facilities’ defects were design deficiencies (3.67), intensity of use (3.53), level of exposure to climatic condition (3.41), inadequate maintenance funding (3.19), vandalism (3.18), moisture (3.17) and inadequate cash flow analysis (3.16). The study recommends that users of the facilities should be carried along at the designs stage to minimize design errors and also adequate fund should be provided to maintenance unit to guarantee adequate maintenance of sports facilities for optimal performance.
