Abstract
Development of infrastructural facilities is accompanied by construction, remodeling and demolition of buildings, roads, bridges, flyover, subways, runways, factories and other similar establishments. Construction industry consumes huge amount of natural resources and often generates large quantities of construction waste. A Construction waste consists of unwanted material produced directly or indirectly by the construction industries. This includes inert and non-biodegradable building materials such as concrete, plaster, wood, metal, broken tiles, bricks, masonry, insulation, nails, electrical wiring, and repair, as well as waste originating from the site. These wastes are heavy, having high density, very often occupy considerable storage space. In general, a very high level of waste is assumed to exist in construction. In construction, Material, Manpower, Money Machine plays a crucial role. Depending on the type of a construction project, Building materials account for 60 to 70% of the project cost. Observational research has shown that this can be as high as 10 to 15% of the materials that go into a building, a much higher percentage than the 2.5-5% usually assumed by quantity surveyors and the construction industry.
During the last few years, enormous growth in infrastructure found, by wide range of diversity construction organization. This produces a large range of waste, created at all the stages of construction right from site preparation, demolition to final product. Minimizing the waste and optimizing the profitability is possible by reducing cost of material with proper planning, scheduling, purchasing, procurement, receiving, inspecting, handling, storing and warehousing.
The purpose of this project is to study the sources of material wastage and to suggest the possible way to optimize it. The objectives of the study included the identification of sources and causes of material wastes on construction sites, and identification of barriers to successful implementation of wastage minimization and finding out deviations between actual material wastage on site and allowable standards considered by quantity surveyors for estimation. Only materials wastage on constructions sites are considered for this study because these materials are derived from natural resources and recharge of such resources is not possible.
The main tools for the collection of data included questionnaires, interviews and site observations. The target population for the data collection included project peoples of building construction organizations on construction projects in MIDC Kagal Kolhapur and MIDC Chakan Pune. Suitable computer software and statistical techniques is employed to analyse data obtained. Mean score rankings, standard deviations, were adopted to analyse data.
