This study uses Lagos, Nigeria, as a case study and investigates awareness of 4IR technologies in H&S practices among construction professionals in the Nigerian construction industry. A quantitative research approach was developed to retrieve a structured survey questionnaire from construction stakeholders in the study area. Retrieved data was analysed in three stages: data reliability and validity, descriptive statistics, and exploratory factor analysis (EFA). The descriptive analysis findings and the Kruskal–Wallis H test revealed no significant difference in professionals’ awareness of 4IR technologies in H&S practices in the construction project delivery in Lagos, Nigeria. The findings of the EFA returned four-factor components of H&S practices enabling technologies in the Era of 4I...

It is against this background that this study appraised students' maintenance requirements in the hall of residence on the facility provided for Higher Educational Institution (HEI) using Covenant University Ota, a leading private University in Nigeria, as a case study. Structured Questionnaires were distributed through systematic random sampling techniques to 198 respondents, to collect data on their maintenance requirements from the maintenance management unit. The result of the study indicates that most maintenance request by the student in HEI facility is majorly on floor and wall, reading tables and chairs, together with lockers and door locks. The study found out that acknowledgment of maintenance request by maintenance personnel was prompt but the actual repairs take time. The studies further showed that vandalism, lack of user's specification and use of substandard material during replacement were some of the significant factors causing damage to facilities in HEIs. The study concluded that to meet maintenance requirements of students' in HEI hostels, the facility provided should be maintainable, serviceable, and replaceable within the hall of residence and a maintenance operations manual should be provided for maintenance personnel to develop a maintenance standard in meeting the students' immediate maintenance requirements.

These aggregates are left dormant and exposed to harsh weather conditions before utilization. This study investigates the effect of aggregate dormancy of both fine aggregate (river sand) and coarse aggregate (gravel) on quality of concrete produced and its strength. Data for the study was collected over a 3 years dormant period of the aggregates, to determine the efficiency of the aggregates and its quality on concrete production and its strength. Experimental procedures such as; silt content, water absorption, specific gravity, sieve analysis, and the compressive strength test were conducted on the dormant aggregates to analyse its quality and strength of concrete produced through it. The analysis of the performed experiment on the dormant aggregates was presented through tables and figures. The finding of the study shows that that the strength of the concrete increases yearly due to reduction of silt content, high specific gravity, and an increase in the water absorption of the dormant aggregates. Base on the finding of this study, it is concluded that the dormancy of aggregates (river sand and gravel) have no effect on the concrete quality and its strength.

The strength of any building component, constructed using concrete will depend on the type and texture of aggregates used. It is on this base that this study analysed two different types of coarse aggregate (crushed granite and washed gravel) used in the production of concrete for higher educational institution (HEI) buildings. The following experimental procedures such as silt content, water absorption, specific gravity, sieve analysis, were conducted on the aggregates sampled to determine the property quality of the aggregates when used with other adhesive. Concrete of ratio 1:2:4 were produced using crushed granite and the washed gravel sampled and its strength was tested with the compressive strength testing machine. The 28 days average compressive test of concrete produced with crushed granite and washed gravel are 23.36 N/mm² and 20.44N/mm² respectively. The study suggests that locally sourced gravel should be washed before use to reduced silt content and impurities in the coarse aggregate. The study concludes that base on the compressive strength result of the study both crushed granite and washed gravel can be used for concrete work in construction work or project, but their selection for usage should be based on expected imposed load.

The industry is also known to be a major source of pollution, waste, and other adverse environmental issues within the built environment. It is therefore imperative to introduce strategies, processes, materials, and technologies that have the potential to revolutionize the CI to a sustainable state, especially in this fourth industrial revolution (4IR) era. Futuristic building materials (FBMs) are the generation of novel and cutting-edge materials with significant potential to solve ongoing challenges and address environmental issues attributed to the CI. Hence, the objective of this paper is to evaluate the hindrances to the utilization of FBMs in realizing a sustainable CI in South Africa. The quantitative research approach was employed in this study. A structured questionnaire survey was administered to construction professionals in the South African constr...

The industry experiences difficulties in achieving project success globally and nationally due to insufficient planning. Technology is required to address this issue by incorporating it into the project planning phase. Therefore, BIM is considered the necessary tool to bridge this gap. This research aims to examine the advantages of implementing BIM during the project planning stage of construction projects. To gather data, a quantitative research approach was employed, and professionals in the South African built environment were surveyed using a questionnaire. The data collected were analysed using descriptive and inferential analysis. Findings from the analysis discovered that the top three measures to improve BIM implementation for project planning in the construction industry are competitive advantage, cost and time savings, and collaboration among AEC professionals. The research concluded that these measures could encourage the adoption of BIM among construction professionals in South Africa.
