Abstract
Medication adherence contributes significantly to symptom remission, recovery and wellbeing in mental illnesses. We evaluated how medication adherence correlates with clinico-demographic factors and quality of life (QoL) in a sample of Nigerians with schizophrenia. This descriptive cross-sectional study involved 160 randomly selected participants with confirmed diagnosis of schizophrenia based on MINI International Neuropsychiatric Interview. Data on socio-demographic and clinical characteristics of participants were collected with a questionnaire. Medication adherence was assessed with Morisky Medication Adherence Questionnaire, and participants completed the World Health Organization Quality of Life Scale-BREF. The mean age of participants was 38.54 (±11.30) years, and all the participants were on antipsychotics, but only 45% were adherent to their medication. Out of all the participants, 45 (28.2%) considered their overall QoL to be good, 97 (60.6%) considered theirs to be fair, while 18 (11.2%) reported poor QoL. Medication non-adherence correlated negatively with good QoL across multiple dimensions including overall QoL (r=−0.175), health satisfaction (r=-0.161), physical (r=-0.186) and psychological domain (r=-0.175). Again, participant's age (r=−0.190) and age of onset of illness (r=-0.172) correlated negatively with medication non-adherence, and a trend towards relapse delay with medication adherence was also observed (r=-0.155). The effect size of these correlations were however small. Our findings suggest a link between medication adherence and QoL in schizophrenia, such that strategy that addresses medication non-adherence and its determinants may have potential benefits on wellbeing. Further hypotheses-driven studies are desirable.

Abstract
The challenges confronting the Nigerian construction industry which led to the adoption of supply chain management (SCM) practice were evaluated in this chapter. It was discovered that the Nigerian construction industry is confronted with fragmentation and poor information management. The stakeholders within the Nigerian construction industry proposed the adoption of SCM to overcome the fragmentation and other shenanigans facing the industry. This chapter revealed that construction supply chain (CSC) practices within the Nigerian construction industry focus on waste elimination by adopting the lean concept. The focus on the lean concept could be attributed to the numerous research related to lean or the enormous waste emanating from the Nigerian construction industry. Regardless of the emphasis on lean, the Nigerian CSC is still confronted with fragmentation and heavy waste generation. Thus, this chapter proposed the adoption of principles and technologies driven by the fourth industrial revolution (4IR) is a paradigm shift for the management of CSC in the country. It was discovered in this chapter that Nigerian construction supply stakeholders had not embraced the technologies and principles of the 4IR. The failure to adopt the technologies driven by the 4IR is attributed to the absence of a CSC model that depicts the management of CSC in alignment with the 4IR. This chapter called for developing a SCM model for the Nigerian construction industry in tandem with the principles and technologies of the 4IR.

Abstract
Purpose
This paper aims to appraise a decade (2004-2013) of annual financial statements of 58 locally owned construction firms’ (LOCOFs’) financial statements on turnover, fixed assets, gross profit and after-tax profit to assess their financial performance in the Nigerian construction industry. It serves as a check on firms’ financial performance, analysis and benchmarking of LOCOFs’ financial statement values to assess firms’ financial health and psychosocial environment.
Design/methodology/approach
A purposively sampled frame of 580 LOCOFs’ financial values (turnover, fixed asset and gross profit) from 212 turnover, 207 fixed assets, 184 gross profit and 217 after-tax profit data points was obtained. Firms’ capacities were obtained by categorisation, industrial average median was obtained and a regression analysis was used to describe the relationship and test of significance of the variables. A review of the possible effect of the research findings on LOCOFs’ psychosocial environment was undertaken.
Findings
Most LOCOFs were categorised as micro scale construction contracting business enterprises. LOCOFs’ financial performance was less than the performance of similar construction firm types and profits were not necessarily influenced by the cost of its investments on fixed asset but rather on firms’ turnover.
Research limitations/implications
A limitation of this study is the paucity of financial data because of poor information access and storage.
Practical implications
The paper recommends more funding of infrastructural developmental projects and better patronage of LOCOFs which will positively influence firms’ turnover, profit and the psychosocial well-being of organisation and personnel.
Originality/value
This paper fulfils an identified need to periodically assess LOCOFs’ financial values so as to appraise financial performance and its possible effect on firms’ psychosocial environment.

Abstract
Purpose
Architecture, engineering and construction (AEC) is an important industry worldwide and one of the largest economic sectors in several developing countries, particularly in Iran. The Iranian AEC sector suffers from low productivity and needs to adopt building information modeling (BIM) to reduce inefficiencies. Therefore, this paper was conducted to identify the BIM barriers and propose practical solutions to overcome them in Iran.
Design/methodology/approach
A comprehensive literature review, two rounds of the Delphi technique and semi-structured interviews with 12 Iranian experts in the AEC sector were conducted. The data were analyzed using the mean score, standard deviation and nonparametric tests.
Findings
The present study identified 26 BIM barriers in the Iranian AEC community and provided practical strategies for improving BIM adoption. The identified barriers were categorized into six main groups including source barriers, financial barriers, unawareness barriers, organizational barriers, regulatory barriers and market-demand barriers. The main three BIM barriers in Iran were the lack of government intervention, change-resistant and the gap between industry and academia. Kruskal–Wallis tests revealed that there are no statistically significant differences in perceptions of BIM barriers between respondents. The Mann–Whitney test indicated that there is no statistically significant difference in perceptions between engineers and architects except for one.
Originality/value
There are few studies on BIM adoption across developing countries, particularly in Iran. Moreover, the results can also be used in other developing nations with similar conditions.

Abstract
Purpose
This study examined factors influencing the organisational capabilities of the public sector for building information modelling (BIM) implementation in construction projects with a view to enhancing the performance of public sector projects.
Design/methodology/approach
The study adopted a quantitative descriptive analysis that was based on primary data. In total, 198 valid questionnaires obtained from construction professionals within the public sector provided primary quantitative data for the assessment. The respondents provided the responses on the factors which were identified through an in-depth synthesis of literature relating to organisational capabilities of the public sector. Data collected were analysed using descriptive and inferential statistics.
Findings
The findings established that the potential of the public sector to deploy BIM in construction projects is greatly influenced by varying degree of organisational capability attributes with bureaucratic culture (mean score, MS = 3.37), structural complexity (MS = 3.17), lack of skilled and trained staff (MS = 3.12), personnel stability (MS = 3.11), staff cooperation (MS = 3.09) and political constraint (MS = 3.07) ranked highest. Through factor analysis, these and other highly influential factors were grouped into eight components, namely management-related, policy-related, technical-related, attitude-related, work structure-related, work ethic-related, decision-related and feedback-related factors. This grouping reflects the various components of organisational capability attributes which the public sector needs to efficiently develop to benefit from project management paradigm introduced by BIM.
Practical implications
This study provided information for improving specific capability attributes with respect to human and technical resources as well as other soft infrastructure to support BIM implementation on building projects by the public sector client. The study also serves as a guide for understanding BIM implementation by the public sector in similar socio-political and economic contexts.
Originality/value
This assessment indicates various degrees by which the organisational attributes of public sector have influenced the attributes' capability to implement BIM on construction projects. Thus, findings provide information on areas of improvement for better implementation of BIM by the public sector in project delivery.

Abstract
Purpose
This study aims to evaluate and investigate the dynamics of the barriers to building information modelling (BIM) adoption from the perspective of small and medium-sized enterprises (SMEs) in developing countries with the Nigerian construction industry as a case study.
Design/methodology/approach
An interpretive structural modelling approach was adopted to develop a hierarchical model of the interrelationships of the barriers. Also, the Matrice d’Impacts croises-multipication applique a classement analysis was used for categorisation of the barriers.
Findings
The findings revealed that the barriers are from a sociotechnical context and that SMEs have the will to drive BIM adoption by focussing more on their internal environment.
Originality/value
This study presented the adoption of BIM in SMEs, which is underrepresented in extant studies. Also, it contributes to the nascent discussion of BIM from the perspective of SMEs in developing countries.

Abstract
Purpose
Although studies have shown the relevance of building information modeling (BIM) in cost estimating process, efforts at investigating BIM based detailed cost estimating among professional quantity surveyors through quantitative approach are scanty. The purpose of this study is to identify and examine the usage of BIM-based detailed cost estimating software and assesses the drivers to BIM adoption within the Nigerian quantity surveying consulting firms.
Design/methodology/approach
A comprehensive literature review, pilot study and questionnaire survey were adopted. The survey targeted both the BIM users and non- BIM users’ quantity surveying consulting firms in Lagos, Nigeria. The data collected were analyzed using frequency, percentage, mean score, standard deviation, Mann–Whitney test and factor analysis.
Findings
The study found that 46.58 per cent of quantity surveying consulting firms are aware of BIM and have adopted it for detailed cost estimating, while 49.32 per cent of quantity surveying consulting firms are aware but have not adopted BIM-based detailed cost estimating, and 4.10 per cent of quantity surveying consulting firms are not aware at all. Also, the study identified various BIM-based detailed cost estimating software used in quantity surveying practices and found that Microsoft Excel is often used alongside 3D software, Autodesk QTO, Navisworks, Innovaya Composer and CostX are prevalent BIM software used for detailed cost estimating. In addition, the study identified 21 drivers to the adoption of BIM in quantity surveying practices. The result of factor analysis grouped the 21 identified drivers into five principal factors: improved whole lifecycle/design quality, enhanced decision and visualization, cost and time saving, marketing and support for quantity surveyor tasks and government and client pressure.
Practical implications
This study provides significant insight into the application of BIM to quantity surveying consulting practices, thereby enabling consultant quantity surveyors to make informed decisions to select BIM cost estimating software to suit their practices. Further, the study findings can be useful for individuals’, clients’ and contractors’ quantity surveyors to be fully aware of the opportunities BIM could bring in relation to their service delivery.
Originality/value
Accurate cost estimating, effective cost monitoring and control are essential elements to a construction project success. This study further emphasized the importance of BIM to quantity surveying practices, particularly in the area of the detailed cost estimating.

Abstract
Purpose
Building information modeling (BIM) is vital in the performance improvement of contracting firms. Thus, there is a need to stimulate its implementation in the construction sector with a view to meeting the competitive demands of the industry. However, there have been very few studies on BIM implementation among contracting firms in Nigeria. Hence, this study aims to examine the current BIM uptake among Nigerian contracting firms, assess the barriers to BIM implementation and examine the ways of improving BIM implementation within these contracting firms.
Design/methodology/approach
A questionnaire survey was conducted on contracting firms (comprising small-, medium- and large-sized firms) in Lagos, Nigeria. The obtained data were analyzed using both descriptive and inferential statistics. These included percentage, mean score, standard deviation, the Kruskal–Wallis test and factor analysis.
Findings
This study revealed the current state of BIM implementation among contracting firms in Nigeria in terms of their knowledge of BIM, their usage of BIM as well as the BIM software adopted. Furthermore, the study identified 25 barriers to BIM implementation in contracting firms and identified 15 ways to improve BIM implementation in contracting firms. The relative importance of both the identified barriers and the ways for improving BIM implementation was gauged among contracting firms comprising small-, medium- and large-sized firms. The result of the Kruskal–Wallis test revealed that, except for two (out of 25) identified barriers, and one (out of 15) identified ways of improving BIM implementation in contracting firms, there is no significant statistical difference in the perceptions of the three respondents’ groups. The result of the factor analysis categorized the identified 25 barriers into seven main factors.
Practical implications
This study provides empirical evidence on the barriers to BIM implementation and the ways of improving its implementation among contracting firms, thereby providing a better insight of the Nigerian construction industry’s BIM environment.
Originality/value
This study’s findings can positively inform the decisions of construction stakeholders to formulate strategies capable of improving BIM implementation in the construction industry at large.

Abstract
Purpose
The era of digital construction, including building information modelling (BIM), has placed a high demand for a seamless collaboration of people, technology and processes in meeting a project delivery. The project actors involved in a BIM process must ensure compliance with all regulations and contractual requirements from inception. While many studies have disclosed the various contractual implications arising from BIM implementation, little has been examined on the current state of BIM in contract administration practice, particularly in the Malaysian construction industry. This study aims to explore the current state of BIM implementation with specific reference to a design-and-build construction project.
Design/methodology/approach
The exploratory case study involved the construction of a public complex. Semi-structured interviews were carried out with the project actors, and document analysis was performed on the project’s contractual guidelines to derive the findings.
Findings
Findings from the thematic analysis revealed the following five sequences of activities that guided the contract administration practices, particularly during the pre-contract and post-contract stages of a BIM-based construction project: project inception, tendering phase, detailed design, construction and preparation for the handing over phase. Most of the activities were conducted to deliver the final BIM outputs successfully. Nevertheless, some shortcomings were noted in the project monitoring, the validation process of the BIM deliverables and the BIM players’ competency level in fulfilling the specified BIM contractual requirements.
Practical implications
The study contributes to a practical understanding of how BIM can affect project administration and how a public client can improve contractual risk allocation in future BIM implementation.
Originality/value
This paper discloses the current practices of contract administration to better understand the impacts of BIM management during the pre-contract and post-contract stages of a BIM-based construction project.

Abstract
Purpose
The skills and knowledge of site supervisors play an important role in the outcome of construction projects. Evidence gleaned from the literature indicates that poor performance of construction projects remains a central concern for stakeholders in the construction sector. This suggests that the site supervisor’s training is important in the construction project outcomes. Various training programmes are available for site supervisors, yet construction firms are not satisfied with them. The purpose of this study is to determine the key training practice indicators for optimal site supervisor’s usage in construction firms.
Design/methodology/approach
This study adopts a cross-sectional survey research design. In the approach, exploratory factor analysis and confirmatory factor analysis were used to determine the key training practice indicators for site supervisors. Data were collected from 218 construction site supervisors using a questionnaire.
Findings
Findings show that training practices are a multidimensional concept consisting of training needs assessment, training delivery, training evaluation and transfer. From the 50 training practice variables, this study establishes 12 key training practice indicators for training site supervisors in construction firms.
Research limitations/implications
Future research should adopt a longitudinal survey for examining training practices in construction firms.
Practical implications
The identified key training indicators can inform the policies and practices used in the training of site supervisors.
Originality/value
This study contributes to knowledge by establishing 12 significant training practice indicators for optimal site supervisors’ usage in construction firms.
