AN APPRAISAL ON THE MINIMIZATION OF WASTE IN CONSTRUCTION SITES IN MINNA METROPOLIS

Abstract

This research work was designed to assess waste minimization in building construction sites. The main objectives of this work are: to identify the sort of construction waste often generated on site, to identify the importance of waste control in the construction industry, to identify the causes of waste on construction site, and lastly to identify the ways to be taken to reduce waste on construction sites. Literature reviews have been forwarded to examine the objectives and elaborate more on it. A survey research design was adopted for the study, were data was collected through questionnaires, in research, administered to companies, and professionals in the area of study, and the data gathered were carefully analysed and assessed, and presented by the use of tables. The target population for the study is 62 which consisted of 38 architects and 23 site engineers on the construction sites. The three hypotheses tested at 0.05 level of significance. The study finds out that there’s no professional in the building construction industry that wants abundant waste on site; the study also found that waste is a common thing/phenomenon encountered in a construction site; it was also discovered that waste minimization is not highly important in building construction site to the professionals. After the study of the causes of construction waste, the following recommendations are made in order to minimize the accumulation of waste on construction site: contractors are advised to focus on quality in the construction activities so as to mitigate rework, which is identified as the major cause of material wastage on site. Contractors should secure safer smoother means of transporting materials to sites in order to reduce the wastage incurred through the difficulties in transportation. Clients should be enjoined to provide the necessary information to lessen last minute changes so that contractors can effectively manage their materials.
