Assessing the Magnitude of Waste Material Using Lean Construction

Abstract

Purpose: Wastage of construction material always results in cost overrun not only for the construction cost of the project but also for the management and disposal cost of such construction waste. It is interesting to evaluate the magnitude of waste material based on the lean construction approach.

Design/Methodology/Approach: The present study adopted both primary as key informant interviews and secondary bills documents to analyze the Percentage of waste.

Findings/Result: The findings reveal that average wastage of material with standard deviation for five construction projects: rebar (2.096±1.09), bricks (2.56±0.77), cement (2.82±0.672), sand (3.634±0.5325), and aggregate (7.486±4.76). Compared with the other similar studies, waste percentages found are quite low because of adopting the lean construction approaches in the construction site. In the project, some of the wastage can be recycled and reused so the percentage of waste material is low due to the implementation of lean construction approaches. The practice of various reuse strategies like use of broken bricks in soling, cut a piece of rebar in the casting of a large number of manholes manhole grating, waste sand in Hume pipe bedding and backfilling, etc. Expire cement are used in unstructured work, cover block and aggregate are used for different purpose of construction..

Originality/Value: The study contributes by illustrating situation of wastage to implement lean construction. Governmental agencies, clients, consultants, and contractors are interested in waste management in building construction projects.
