Analytical study of the causes of material waste in implementing the construction envelopes in Egypt

Abstract EN

The construction industry consumes a large portion of the raw materialsand generates an enormous amount of solid waste annually especially in installingthe building envelope.

Despite the positive impact of the building envelope on achieving theeconomic development goals of the countries, it has been proven that the wastegenerated from the construction and installation processes has a significantnegative impact on the economy and the environment, which led to a waste of10% of the cost of project materials according to global statistics in 2010.

This paper aims to (1) identify the causes and impacts of wasted materials, (2) present the results of the field study conducted by the authors to investigate thecauses of material waste in the implementation of building envelopes in Egypt, (3)identify the most important, sub-factors and causes of material waste in theimplementation of building envelopes in Egypt.

(4) Based on expert s' opinions, recommendations are made to avoid wasting materials in implementing buildingenvelopes in Egypt.
