    An alternative sustainable walling material for building projects in construction industry
    (ASOCSA2023, 2023) Oladiran O.J.; Anugwo I.C.; Simeon D.R.
    Purpose Autoclaved Aerated Concrete (AAC) is an eco-friendly and sustainable material. This study evaluates the acceptability and key drivers as a walling material. Design methodology Seventeen online questionnaires were sent via email to South African construction practitioners in five provinces and 99 questionnaires self-administered to construction professionals in Lagos, Nigeria. The statistical techniques used for analyses were frequency distribution, percentages, ranking, mean score and percentage mean unit. Findings The top four AAC block types used in building projects in South Africa are those AAC made using Ordinary Portland Cement (OPC) of grade 52.5, OPC of grade 42.5, Aluminum Powder (AP) or Rice Husk Ash (RHA), and Palm Oil Fuel Ash (POFA) or Pulverized Fuel Ash (PFA). The top factors influencing the use of AAC in Nigeria are its lightweight characteristics, ecological improvements, energy efficiency, adaptation to hot regions, excellent heat assimilation characteristics, good fire resistance, and adaptability to architectural flairs. Whereas, AAC is mostly used in South Africa due to its outstanding fire insulation properties, lightweight characteristics, energy efficiency, superior thermal absorption characteristics, adaptability to any type of architecture, eco-friendliness; and remarkable thermal conductivity. Research implications The research draws the conclusion that AAC block producers that manufacture AAC variations outside the four listed above would probably not grow in business since they would receive little support from construction practitioners. Practical implications Although lightweight characteristics is the most important driver for both nations, the relevance of drivers for the use of AAC blocks varies. This suggests that practitioners in both nations prioritize the block's lightweight properties, which could be preferred for tall projects due to lower costs for the foundation and other structural components.

    Measures for stakeholders’ participation and grievance management in Transmission Company of Nigeria (TCN) projects’.
    (ASOCSA2023, 2023) Oladiran O.J.; Anugwo I.C.; Ojelabi R.A.; Bamidele O.
    Purpose The participation of stakeholders and grievance management are critical components of stakeholders’ engagement. This study aims to assess measures for stakeholders' engagement and grievance management on TCN projects in Nigeria. The objectives are to determine the frequency of use of measures for stakeholders’ participation and grievance management measures in TCN Power projects. Design methodology The study used a survey research approach. The population was divided into two groups: construction professionals and electricity consumers. The study employed a multi-sampling strategy that included both purposeful and simple random sampling techniques. Structured self-administered questionnaires were used to extract information from the respondents in Lagos. Each of the first and second groups of participants received 50 copies of the questionnaire, while 29 and 41 questionnaires were returned, indicating 58% and 82% response rates for the two groups respectively. Data were analyzed using frequency, percentages, mean scores and ranking. Findings Results indicate that supervision and control is the most frequently used measure for stakeholders’ participation; while decisions at the design stage to ensure proper planning and review of project plans and specifications is the commonest used grievance management measure. Research implications The study concludes that grievance management measures are commonly engaged in TCN projects, however, appropriate decisions at the design stage and consultations with the stakeholders before project commencement are among the commonest. The implication is that conflicts could tend to be lesser in TCN projects. The study recommends that TCN organizations and professionals should be cognizant of the various measures established in this research for full implementation on projects. This can be achieved through appropriate dissemination.
