This study evaluated compliance of concreting materials with standards in building project delivery. It examined the factors that influence compliance with standards of materials used for producing concrete elements. A quantitative approach was adopted in the study where structured questionnaires were administered to designers and constructors (such as architects, engineers/site supervisors and quantity surveyors) in consulting and contracting organisations in Lagos State, Nigeria. The data were analysed using frequency distribution, mean score, standard deviation, factor analysis and Kruskal Wallis test. Factors affecting compliance of materials with standards were categorised into construction site-based and procurement-based. These are technical, regulation, procurement, capacity, performance, and skill. The study provides i...

Findings established that 90.24% of the respondents were aware of intelligent building systems, while practitioners who have worked or were working on buildings with intelligent features were limited to 51.2%. Approximately 64.60% of the respondents have used intelligent buildings previously, but only thirteen (13) notable buildings were identified to have employed intelligent building systems to a reasonable extent in the study area. The features of intelligent buildings with top level of awareness were CCTV system; access control and locks (mean = 3.96); alarms and alerts (mean = 3.92); HVAC system (mean = 3.90), and fire alarm system (mean = 3.89). Features with high level of utilisation include lighting system, which was the most utilised feature (mean = 3.57); fire alarm system (mean = 3.48); access control and lock; CCTV system (mean = 3.45), and HVAC system (mean = 3.43). The results showed that most of the features with a high level of awareness were also those with a high level of utilisation. The study established that the level of awareness and utilisation of intelligent building systems in the study area is high, but full adoption of the system is still low.

Factors affecting compliance of materials with standards were categorised into construction site-based and procurement-based. These are technical, regulation, procurement, capacity, performance, and skill. The study provides implications for quality building production through improved compliance of concreting materials to standards. It also found the neglect of the use of structural engineers' services and limited standards observance on site. These lead to substandard components and elements production. It therefore, recommends efficient regulatory policies, enforcement mechanisms, improved training and instilling ethical standards among project stakeholders.

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 5 3.37), structural complexity (MS 5 3.17), lack of skilled and trained staff (MS 5 3.12), personnel stability (MS 5 3.11), staff cooperation (MS 5 3.09) and political constraint (MS 5 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.

This study examines the organisational capability attributes required for the implementation of BIM in construction projects, with a view to enhancing the performance of public sector projects. The study adopted a quantitative descriptive analysis based on primary data obtained from public sector organisations in Lagos State, Southwestern Nigeria. One hundred and ninety- eight (198) valid questionnaires, obtained from construction professionals within the organisations, provided quantitative data for the assessment. Data collected were analysed, using both descriptive and inferential statistics. The findings indicate that public sector organisations possess the capability attributes for BIM implementation in building projects at different levels of availability (LAv) and adequacy (LAq), with adequate power supply rated at (LAv = 76.00%; LAq = 75.80%); speedy internet connection (LAv = 70.20%; LAq = 69.80%); change from traditional workflow (LAv = 69.80%; LAq = 64.60%); adequate work environment for workers (LAv = 69.60%; LAq = 64.40%); standardised process (LAv = 66.00%; LAq = 63.40%); sufficient number of workers (LAv = 65.60%) and data-sharing skills (LAv = 65.00%); standardised process (LAq = 63.40%), and collaborative team culture (LAq = 63.00%). The study established that the organisational capability attributes with high availability rating also have high adequacy rating. The research concludes that the general organisational capability attributes of the public sector for BIM on construction projects are not yet sufficiently developed and thus suggests the need to strengthen specific capability attributes that are required to implement BIM.

These were with a view to providing information that could enhance the performance of public sector projects in Lagos, Nigeria.Primary data were used for this study. The data were collected through copies of structured questionnaire. Random sampling technique was used to administered the questionnaire on one hundred and ninety-eight (198) construction professionals of Lagos State Public Service. Data were collected on the organisational capability attributes of the public sector for BIM implementation, the maturity level of capability attributes of the public sector in relation to BIM implementation, factors influencing the organisational capabilities of the public sector for BIM implementation and capabilities improvement measures required by the public sector. The data collected were analysed using mean score, factor analysis and Kruskal-Wallis test.The results showed that adequate power supply with level of availability (LAv) = 76.00%, speedy internet connection (LAv = 70.20%), change from traditional workflow (LAv = 69.8%) and adequate work environment (LAv = 69.60%) were the organisational capability attributes of the public sector rated with high level of availability. The results also showed that these four organisational capability attributes were also rated with high level of adequacy (LAq), with LAq = 75.80%, 69.80%, 64.60%, and 64.40% respectively. The organisational capability attributes with high maturity levels were adequate power supply (ML = 75.60%), speedy internet connection (ML = 69.40%), data sharing skills (ML = 63.80%), adequate work environment for workers and continuous on the job training (ML = 63.20%). Further results of the analysis showed that bureaucratic culture (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) were the most significant factors influencing the capability attributes of the public sector. The result of this study also showed that team-based structure and adequate number of staff (MS = 3.66), government support and involvement (MS = 3.60) were the most frequently used capability improvement measures. Reward system for performance (MS = 3.81), government policies (MS = 3.74), education and training of staff (MS = 3.74), government support and involvement (MS = 3.73) were identified as the most efficient capability improvement measures used by the public sector. The study concluded that the overall maturity level of organisational capability attributes of the public sector in relation to BIM implementation is on the average and these capability attributes are significantly influenced by organisational framework, government support and involvement; as such reward system based on employees’ performance, government policies and the culture of investment in employees will improve the capabilities of the public sector for BIM implementation to enhance public project delivery

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 5 3.37), structural complexity (MS 5 3.17), lack of skilled and trained staff (MS 5 3.12), personnel stability (MS 5 3.11), staff cooperation (MS 5 3.09) and political constraint (MS 5 3.07) ranked highest.

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.
for overcoming the problem of fragmentation in the construction industry. This study examines the
organisational capability attributes required for the implementation of BIM in construction projects, with a view to enhancing the performance of public sector projects. The study adopted a quantitative descriptive analysis based on primary data obtained
from public sector organisations in Lagos State, Southwestern Nigeria. One hundred and ninety-
eight (198) valid questionnaires, obtained from construction professionals within the organisations, provided quantitative data for the assessment. Data collected were analysed, using both descriptive
and inferential statistics. The findings indicate that public sector organisations possess the capability attributes for BIM implementation in building projects at different levels of availability (LAv) and adequacy (LAq), with adequate power supply rated at (LAv = 76.00%; LAq = 75.80%); speedy internet connection (LAv = 70.20%; LAq =
69.80%); change from traditional workflow (LAv = 69.80%; LAq = 64.60%); adequate work environment for workers (LAv = 69.60%; LAq = 64.40%); standardised process (LAv = 66.00%; LAq = 63.40%); sufficient number of workers (LAv = 65.60%) and data-sharing skills (LAv = 65.00%); standardised process (LAq = 63.40%), and collaborative
team culture (LAq = 63.00%). The study established that the organisational capability attributes with high availability rating also have high adequacy rating. The research concludes that the general organisational capability attributes of the public sector for
BIM on construction projects are not yet sufficiently developed and thus suggests the need to strengthen specific capability attributes that are required to implement BIM.

attributes of the public sector rated with high level of availability. The results also showed that these four organisational capability attributes were also rated with high level of adequacy (LAq), with LAq = 75.80%, 69.80%, 64.60%, and 64.40% respectively. The organisational capability attributes with high maturity levels were adequate power supply (ML = 75.60%), speedy internet connection (ML = 69.40%), data sharing skills (ML = 63.80%), adequate work environment for workers and continuous on the job training (ML = 63.20%). Further results of the analysis showed that bureaucratic culture (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) were the most significant factors influencing the capability attributes of the public sector. The result of this study also showed that team-based structure and adequate number of staff (MS = 3.66), government support and involvement (MS = 3.60) were the most frequently used capability improvement measures. Reward system for performance (MS = 3.81), government policies (MS = 3.74), education and training of staff (MS = 3.74), government support and involvement (MS = 3.73) were identified as the most efficient capability improvement measures used by the public sector. The study concluded that the overall maturity level of organisational capability attributes of the public sector in relation to BIM implementation is on the average and these capability attributes are significantly influenced by organisational framework, government support and involvement; as such reward system based on employees’ performance, government policies and the culture of investment in employees will improve the capabilities of the public sector for BIM implementation to enhance public project delivery
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.
