There have been few studies that have focused on the adoption of BIM in the Nigerian construction market. This is also one of the problems preventing innovation in the Nigerian construction industry.
Research Methodology
In order to identify the challenges in BIM adoption and the lack of cooperation between professionals and disciplines in the construction industry, it is necessary to develop measures for BIM cooperation. Measurement of participation in BIM will include: personal and team characteristics, human interactions within the BIM model, communication channels for team members as well as physical locations of team members.
Finding and Discussion
Conclusion
Lack of trained personnel was identified as one of the biggest barriers to BIM adoption. The research shows that customer satisfaction and improvement in drawing quality are the main benefits of adopting BIM during the schematic design phase.
Recommendation
There is a need for more research on the use of BIM in construction in Nigeria.

Introduction
Based on the findings, it was concluded that the causes of errors in contract documents vary from one state to another. It was also found that there is a difference in the causes of errors in contract documents based on types of buildings, services provided by construction organizations and states in South West, Nigeria.

Literature Review
Therefore, it is necessary to determine the frequency of the causes of errors in the contract documentation on construction projects. Therefore, a similar study should be conducted on the subject to identify the common causes of errors in Nigerian contract documentation.
Research Method
Yates and Lockley (2002) classified the causes of failures into design, construction, material, administrative and maintenance failures. From the literature reviewed so far, it is clear that the causes of errors in contract documentation are different from one country to another, so their enormity warrants categorization.
Data Presentation and Analysis
-23 17 Table 5: Causes of errors in contract documents according to the type of building projects and their change test. ANOVA) test conducted to determine if there are differences in respondents' perception of the causes of errors in contract documents based on types. However, the ANOVA test conducted shows that there are significant differences in eleven (11) of the forty-four (44) causes of errors in the contract documents studied.
In Ekiti State, the major causes of errors in contract documents are the professional training of designers. The implication of this analysis is that the causes of errors in contract documents vary from state to state.
Conclusion

- Conclusion
- Limitation of the Study
In the context of low-income housing, a resident's perception of the quality of his/her building will be related to how 'good' it is. This study fills this gap by relating the physical characteristics of buildings (measured by QI) as well as occupants' perception of the features (measured by RCI) to building maintenance costs. The quality indices of building elements calculated on the basis of these data are presented in Table 5.
It is indicative that residents' perception of the physical condition of their buildings is not related to the quality of materials used in their construction. Perceptions of the quality of low-income housing in South Africa: defects and their causes.
Background of Study
Moreover, many of the problems of urban areas can be traced back to shortcomings in rural areas. The wide gap in development levels between urban and rural areas in Nigeria also appears to threaten the political and social stability of the country. It includes the interactions between the organization of the housing market (the institutional structure), the actors (supply and demand) and housing policy, in particular the economic, demographic, political and spatial factors that influence them (Van der Heijden, 2013).
Ebadi et al (2015) examined the functional changes of rural settlements in southwestern Tehran during the post-Islamic revolution in Iran. The study found that public sector involvement in housing in Nigeria has been more a matter of policy formulation than of housing delivery.
Data and Methodology
The assessment is time-specific and the study is specifically tailored to measure the impact of the post-Islamic revolution. The study is not primarily targeted at the urban poor, but also focuses primarily on public sector intervention. The questionnaire detailed the respondents' personal characteristics and information about the existing housing structure, its performance and the respondents' preference for housing choices in the area.
Average values were determined from respondents' ratings of the parameters used in measuring housing characteristics and preferences. The resultant figures obtained from each scale were added and divided by the total response for each of the parameters.
Result and Implications
To achieve this, a pilot study was conducted to identify the existing housing finance structure in the area. 4 below presents the result on the extent of the use of alternative sources of housing financing in the area. The result is that cultural and ethnic reasons were perceived as the most important factors affecting housing development in the area.
However, the low level of mechanization in the construction industry of developing countries leaves. In the construction industry of developing countries, personnel represent an important part of project costs.
Research Methods
In addition, they proposed that the government provide incentives or policies that will encourage self-learning through certification of suitability for the profession in the project. There are legislations on minimum wages, recruitment and selection (concerning federal character), training and development, compensation, integration and separation of employees from organizations. Yaro (2014) listed the challenges of public service recruitment in Nigeria to include: interference by political office holders using sentiments and other primary considerations in the recruitment process, the principle of federal character which prescribes ethnic balancing and equal opportunities for applicants from all geopolitical zones and recruiting solely on the basis of technical skills and abilities at the expense of positive attitude and character.
These challenges are not limited to public service but also to construction organizations in Nigeria. Oginni and Afolabi (2012) cited the challenge of “paternalism” and nepotism taking the place of fairness and meritocracy in recruitment and placement in manufacturing organizations in Nigeria.
Results and Discussion
Furthermore, the result indicates that preference for university graduates over polytechnic graduates, recruitment through referrals only, preference for male applicants over female applicants and youth (below 25) over older applicants are sometimes used in the recruitment and selection of HR in the Nigerian construction companies . The results in Table 2 show that the training and development practices most commonly used in the construction companies in Nigeria are: induction and training of newly hired employees, orientation and training of new employees, training in software and use of tools and allocation of personnel based on their skill and expertise. This is in agreement with Huemann et al. 2007) training proposal, but in contrast to Tabassi and Abu Bakar (2009) observation of HRM practices in the Iranian construction industry.
This finding is unexpected in light of barriers to HR development posed by SMEs, self-employed workers and subcontractors in the construction industry (Adeagbo and Oyemogun, 2014). The investigation further revealed that it is rare practice in the Nigerian construction company to send staff for training while they wait for the company to secure other projects and to disengage low performing staff without prior notice.
Conclusions
A study of human resource management practices and labor turnover in manufacturing organizations in Lagos, Nigeria. The study provides evidence that may be useful in the psychometric assessment of safety performance and behaviors of construction workers on construction sites. The objective of this paper is to define and analyze the underlying constructs of safety performance measures related to workers' unhealthy eating behaviors as used in the study.
Furthermore, near misses or close calls were shown to be indicators of safety performance ((Biggs et al. 2009;. Also, workers who were available and willing to participate in the study were included (Etikan et al. 2016).
Findings and Discussion
The questionnaire was accompanied by a cover letter explaining the purpose of the study and informed consent was obtained. Cronbach's alpha and mean inter-item correlations were used to assess the internal consistency reliability of the scale. After analysis, the internal consistency reliability of the tested constructs using both Cronbach's alpha and mean inter-item indices was equally good.
Factor analysis was then performed to determine the percent variance accounted for by each of the ten items. The percentage variability explained by each of the variables is shown in Table 4 and Figure 1.
Study limitations and further research
The study lends support to existing literature advocating the use of both leading and lagging indicators to measure safety performance in the construction industry. This is even more important to assess the safety performance of construction workers to reduce the risks associated with working in an inherently unsafe environment. Lagging and leading measures should therefore be used to evaluate and effectively manage the safety performance of construction workers.
The study provides evidence that could be useful in psychometric evaluation of construction workers' safety performance and behavior on construction sites. By highlighting workers' safety performance/behaviour, construction stakeholders can be enabled to make informed decisions about improving workers' H&S performance, thereby improving the productivity, profit and competitiveness of their businesses.

Traditional safety measures, which are ex post measures that assess safety after injury has occurred, are flawed in that they base the measurement on system failure (Dingsdag et al. 2008; Farooqui et al. 2012).
