ASSESSMENT OF MATERIALS WASTE IN THE CONSTRUCTION INDUSTRY: A VIEW OF CONSTRUCTION OPERATIVES, TRADESMEN AND ARTISANS IN NIGERIA
ABSTRACT
Material waste generated by the activities of the construction industry poses serious danger to both the construction projects concerned and the environment at large. Previous researches both at local and international level have neglected construction operatives and craft men who are the majority stakeholder. The study was aim to assess the perception of construction operatives, Tradesmen and Artisans on materials waste generation in the construction industry, with a view to encouraging better performance of construction projects in Nigeria. The study employed questionnaire survey. Tables and figures where used to present the collected data and Mean item score (MIS) and percentage were used to analyze the data collected. Kruskal-Wallis test and Mann-Whitney U-Test were used to test the hypotheses. It was discovered that formwork from wood/timber, Mortar from Rendering/plastering and Blockwork/ Brickwork are the most wasteful material generated on sites; Design (Frequent design changes and poor design), Poor materials storage system and Theft and vandalism are the most important factors that influence material waste generation during construction; Proper site supervision and management techniques, Adequate storage of material, and Staff training and awareness on waste management are the measures of minimizing construction material waste; and saving cost of disposal and transport, increased profit and save construction time loss are the most important benefits of material waste minimization. It was recommended that site operatives and craft men should be carried along in every management decision regarding waste management plan development as they constitute the major stakeholders on sites.
