    Awareness and Usage of Environmental Waste Management Practices (EWMP) of Contractors on construction sites
    (2021) Oladiran O.J.; Bayewun A.A.; Aderogba A.M.
    Construction wastes pose challenges to contractors and clients of construction projects globally, with significant negative consequences on the environment. This study, therefore, investigates the environmental waste management practices (EWMPs) of contractors on construction sites. The objectives are to determine the level of awareness and adoption of MPs. The population of the study was construction professionals on sites in Lagos State, Nigeria. The random sampling technique was used to select 63 companies out of the 126 construction companies in categories C, D and E of firms registered with Lagos State Public Procurement Agency. The targeted respondents were construction professionals in the selected companies. The questionnaire was used to collect data from respondents. Descriptive statistics tools, including mean, percentage and frequency, were used for analysis. The study's findings reveal that contractors are aware of about 28 out of the 47 EWMPs identified from the literature. These include good site materials storage, ordering an exact amount of materials and checking deliveries properly. It also reveals the strategies that are not used as belonging to material exchange/recyclers' association; polluter pays principle, usage of self-contained mini or mobile concrete crusher. It is concluded that although contractors are aware of 28 EWMPs, 26 EWMPs are used on construction sites which are 60% and 55%, respectively. It implies that awareness determines the usage of the MPs. The implications are that if the awareness of EWMPs is increased, the implementation among construction contractors will be improved. It is therefore recommended that professionals should increase their awareness and usage of the neglected EWMPs. This can be achieved through construction firms, governments and institutions sponsoring the training of professionals on MPs. Also, polluter pays principle and recyclers’ association should be enforced in project implementations. This can be achieved through government legislation and government regulatory policies for project procurements.

    Environmental waste management practice on construction sites: influencing factors and benefits.
    (Federal University of Technology, Akure, Nigeria., 2023) Bayewun A.A.; Oladiran O.J.; Aderogba A.M.
    Several factors are responsible for the adoption of environmental waste management practice (EWMP) on construction sites. The adoption of EWMPs is crucial because of their influence on certain benefits on construction sites. This study was therefore conducted to determine the factors that are germane for their implementation and the benefits derived by the organizations where they are utilized. The objectives of the study are to evaluate important factors that influence decisions on EWMPs’ usage and to examine the benefits of EWMPs on construction sites. The population of the study was construction professionals on sites in Lagos State, Nigeria. Random sampling technique was used to select 63 companies out of the 126 construction companies in categories C, D and E of firms registered with Lagos State Public Procurement Agency. The findings of the study reveal that the highest ranked factor out of the 27 factors considered important for the usage of EWMPs is clear company’s policy while the least important factor is cost savings to reduce waste. Also, the effect of EWMPs is topmost in compliance with law. The study concludes that although there are many important factors for the choice of EWMPs on construction projects, the most important is clear company’s policy. It implies that companies with good policies will most likely implement EWMPs. The study recommends that company’s policies on EWMPs must be clear and well communicated. This can be done by including policies as accompany document with the programme of work and display on all sites.
