    (International Journal of Real Estate Studies, 2020-06) Amuda-yusuf, Ganiyu; Raheem, Wasiu Mayowa; Adebiyi, Ranti Taibat; Abdulraheem, Maimunat Orire; Idris, Soliu; Eluwa, Stephen Eyinaya
    The need to slow down climate change and global warming has made sustainable development major issue among policy makers and world leaders. Awareness on sustainability concept among industry practitioners is crucial in influencing design, materials selection and construction methods. The aim of this study is to examine the level of awareness on key sustainability concepts and factors that influence their adoption during construction by practitioners in Nigeria. Through an online survey, 120 copies of semi-structured questionnaire were administered on built environment practitioners such as architects, engineers, quantity surveyors, and builders working in client, contracting, consulting and academia with 77% response rate. Factorial two-way ANOVA was performed to examine if there are differences in the level of awareness of factors contributing to sustainable construction among the groupings. Also, binomial logit regression analysis was adopted in predicting the factors that significantly influence adoption of sustainability concept among practitioners in construction industry. The study revealed that professionals from client organization recorded highest (3.8) mean score in terms of awareness on sustainability concept followed by those from academia (3.6), consulting (3.0) and contracting (2.2). In terms of factors that significantly influence adoption of sustainability concept during construction, findings from the study revealed that academic qualification (β =2.226, p<0.05) and type of organization (β =1.127, p<0.05) significantly influence adoption of sustainability concept during construction. Practitioners with high academic qualification and those from client organization, exhibited high level of awareness on sustainability concept, this equally influenced their adoption of key elements of sustainability (site planning, energy efficiency, water efficiency, renewable energy, resource conservation, material reuse, indoor environmental quality) during construction. The determination of the level of awareness and adoption of factors contributing to sustainable construction by practitioners will serve as guide to industry practitioners regarding issues to integrate into design and construction project from inception to completion. To improve awareness of sustainable practices in the industry, stakeholders should direct efforts towards organizing seminars, conferences and workshops centered on sustainable construction through the various professional bodies at state and local government levels.

    Barrier Factors Affecting Adoption of Green Building Technologies in Nigeria
    (Built Environment Journal, 2020-06) Amuda-yusuf, Ganiyu; Raheem, Wasiu Mayowa; Adebiyi, Ranti Taibat; Abdulraheem, Maimunat Orire; Idris, Soliu; Eluwa, Stephen Eyinaya
    Greenhouse gas emission from activities in the built environment is increasing exponentially due to increase in building operations. This study aims at determining factors that affect adopting of Green Building Technologies that normally reduce greenhouse gas emissions. To elicit relevant information, online structured questionnaire forms were administered on practitioners who have been involved in green building development in Nigeria. Mean score ranking was adopted in ranking the barriers to green building technologies, while discriminant analysis was performed to examine how organizations groups (client, consulting, contracting, academia) were distinguished on the barrier factors identified. Findings revealed that, out of the 23 barriers factors considered in this research, lack of institutions to formulate policies and set guidelines (mean score -4.5) ranked 1st as barrier to adoption of green building technologies in Nigeria. This is closely followed by lack of information about green products (4.0), low level of awareness about sustainability issues (4.0), human resources and client knowledge, lack of knowledge about green building technologies, high cost of green products, while unavailability of sustainable materials and products ranked the lowest (2.7). only nine factors at 0.05 level of significance entered the discriminant analysis model and emerged as variables with the most significant power in differentiating the organization groupings on the basis of perceived barriers to adoption of green building technologies. The study recommends that there should be strong political will from government to establish institutions that formulate policies on green building technologies.

    Effect of Knowledge and Compliance of Health and Safety Information of Construction Sites workers Safety in Nigeria
    (International Information and Engineering Technology Association, 2020-01) Adebiyi, Ranti Taibat; Babalola, Olubola; Amuda-yusuf, Ganiyu; Rasheed, Abdulkadir Shehu; Olowa, Theophilus Olatunde
    Construction sites have been identified as one of the most hazardous place to work due to high level of health and safety risks. Information on health and safety is therefore required to educate the participants on how to achieve safe working environment. This study therefore examined and analysed level of knowledge and compliance with information on health and safety and the effects on the safety of construction workers in Nigeria. Findings from the study revealed that the workers have average knowledge of health and safety information but demonstrated low level of compliance. The result also established a very strong positive correlation between compliance of health and safety information and safety of workers. However, when the significance of the correlation was tested, the result implied that though there was a positive relationship between compliance and safety of workers, the relationship was not significant. Practically, this meant that compliance alone cannot substantially guarantee workers safety.

    Level of Awareness and Adherence to Health and Safety Regulations in Construction Industry in Kwara State of Nigeria
    (Kaduna State University Environmental Sciences Journal, 2020-02) Adebiyi, Ranti Taibat; Babalola, Olubola; Amuda-yusuf, Ganiyu; Rasheed, Shehu Abdulkadir; Zubair, Musa Abiodun
    Investigation into causes of accidents and ill-health on construction sites in Nigeria revealed poor health and safety performance. Construction workers are approximately three times more likely to suffer from fatal injuries than those in other sectors. This has earned the industry the reputation of being a dangerous or highly hazardous industry. This study therefore evaluates extent to which construction organizations are aware and adhere to Health and Safety Regulations with a view to enhancing safe work environment. Data for the study were collected from construction firms registered with Kwara State Ministry of Housing and Urban Development, Nigeria. The ministry keeps the data base of all registered contracting firms within the state. This revealed a total of fifty-two (52) firms. The use of questionnaire was adopted for data collection. Out of 52 copies of questionnaire administered to respondents, 35 copies were retrieved representing about 67% response rate. The analytical tools used were simple percentage and Relative Importance Index (RII). The findings from the analysis revealed high level of awareness of health and safety regulations (87%). Though few of the regulations were been adhere to: provision of adequate site security (RII value of 4.35), provision of first aid facilities (4.29) and working at height safety precautions (4.18). Use of health and safety file and workers undergoing medical test prior to work were ranked last. The study also unearthed that compliance with health and safety regulations could reduce accidents on construction sites (4.86), raise the organization image (4.51), improve productivity and reduce project delay (4.43). It was concluded that there were high level awareness of health and safety regulations in the construction industry but the level of adherence is relatively low.

    Perception of Construction Industry Practitioners on Success Factors for Green Building Technologies Adoption
    (USEP: Journal of Research Information in Civil Engineering, 2022-02-23) Amuda-yusuf, Ganiyu; Bamimosu, Halimat Adebukola; Idris, Soliu; Adebiyi, Ranti Taibat; Abdulraheem, M.O
    Climate change resulting from global warming is fast becoming an important issue globally. Although there have been numerous empirical studies that have identified critical success factors for green building development. However, there is dearth of studies on success factors for the adoption of Green Building Technologies (GBT) as an integral part of green building development. This study is set to examine the success factors affecting the adoption of GBT as a component of green building development. A comprehensive literature review was conducted to identify success factors affecting GBT. This was followed by administration of questionnaires to industry practitioners engaged in the design and construction of buildings. The mean score (ms) and ranking of the success factors revealed five (5) most important factors as social awareness of GBT benefits (ms 4.0133), availability of social and natural environment condition to adopt GBT (ms 3.9867), availability of stable economic condition (ms 3.8933), demand and competitive advantage (ms 3.8533), and team members‟ technical background (ms 3.8533). Analysis of variance (ANOVA) was conducted to investigate the level of agreement in the perception of industry practitioners based on type of organisations, years of industry experience, academic qualification and professional background. ANOVA results shows that there is no general agreement in the perception of industry practitioners on the ranking of the success factors. In order to ensure adoption of green building technologies, industry stakeholders must ensure that there is incentive for clients to include cost of GBT in the project budget. Additionally, design professionals must be mandated to always incorporate same at the early stage of building projects. This study has contributed to the existing body of knowledge regarding success factors for the adoption of GBT which could guide in formulating policies for its implementation.
