Reducing the Concrete Waste While Optimizing the Cost, Time & Quality in Sri Lankan Construction Industry

Abstract

Construction projects attempt to reduce wastage. In the present days, many projects are moving towards sustainable development while minimizing construction wastage. Among these construction waste material, waste has been recognized as a major problem in the construction industry. Construction Industry consumes a relatively large volume of material that have been wasted due to various reasons. It can happen due to the labour attitude towards the material, labour arrangement, and lack of knowledge in reusing or recycling the material. The main problem arising out of this waste is that it directly influences the project characteristic (Cost, Time & Quality). Along with this material waste ‘Wasting Concrete’ takes a high percentage that must be given considerable attention. The cost related to this concrete waste directly creates unnecessary expenditure for the employer’s budget. As a result, most countries have found several factors to minimize the concrete waste where all stakeholders can collaborate with the project. This research aims to analysed analyse those factors within the Sri Lankan construction projects to reduce the concrete waste based on case studies of three on-going construction projects. Data will be collected by interviewing few stakeholders from each of the selected on-going construction projects. Based on the case study findings, a framework will be developed for the reduction of concrete waste in construction projects, which can lead to a cost effective and on-time completion of projects.
