The Utilization of Building Information Modeling In Nigerian Construction Industry: Challenges and Prospects

The aim of this research is to appraise the challenges and prospects in the use of Building Information Modeling (BIM) in the construction industry in Nigeria. It analyzed the uses of BIM in the construction industry, determined the stakeholders perception of the benefits, risk and benchmarks in the adoption of BIM in construction practice and process. It examined the extent of its interoperability in bringing together the different participants and processes of construction works for efficiency and effective construction management and timely project delivery. It compared the findings with the same studies carried out and/or currently being carried out in many parts of the world. Primary data were collected through structured questionnaires. The questionnaires were distributed and collected through personal contacts, letters, online groups and e-mails. Direct observation and interviews were made with professionals in the construction industry The secondary data were obtained from the exploration of various relevant literature and previous researches that have been done in relevant areas. A purposive and modified BIM measurement survey was used for this research work to gather the opinion and views of various construction professionals and clients A total of One Hundred and Fifty (150) questionnaires were distributed based on the sample population. One Hundred and Thirty-two (132) questionnaires were retrieved and used to obtain the required information for data. Tools used the purpose of this research include mean score, percentile and inferential method of statistical analysis. The statistical package for social science (SPSS) was basically used to create the frequency tables and the charts. The study showed that the application of BIM is economical and easy leading to improvement, enhanced technical and general management of construction projects which can lead to total control of cost estimates, prompt delivery of projects and quality are the most important key performance indicators in construction

Factors Militating Against Prompt Delivery of Construction Projects in Lagos Megacity, Nigeria: Contractors’ Perspective

Delay is a common issue faced in the construction industry all over the world especially in developing countries. The aim of this study is to evaluate factors causing delays and their effects on construction projects in Lagos Mega City, Nigeria from the contractors’ perspective. It is predicated on the incessant delay experienced by contractors on construction projects. Purposive sampling method was adopted for the study;. Quantitative data was obtained by administration of One hundred (100) structured questionnaires distributed to contractors of construction project sites in Lagos State and Qualitative data was obtained from interview of key management personnel of the companies and journals. Ranking analysis of the 33 major causes of delays identified through literature review using Relative Importance Index (RII) showed that cash flow problems during construction (RII=4.81), clients’ financial difficulties (RII=4.47) and poor procurement (RII=4.40) were the most importantt causes of delays in construction project sites in Lagos State, Cost overrun (RII=4.92), late payment (RII=4.59) and project extension (RII=4.45) were predominant effects of delay in construction project. Hypotheses testing on relationship between shortage of skilled labour, improper equipment during construction and delay in construction project using One-Way ANOVA showed positive correlation. For improved efficiency and effective project delivery in the industry, proper payment from client (RII=4.78), competent project managers (RII=4.64), the use o
