Abstract

The construction industry is plagued with significant construction and demolition waste (C&DW) generated during various phases of construction projects. This waste has created a universal, pervasive, and enduring problem globally. To propose practical solutions to resolve this consequential issue, this research adopted a quantitative approach in two stages. The first stage involved an online survey, administrated to 360 methodically selected construction organisations working in Egypt, to evaluate the impact of six main factors on C&DW reduction (C&DWR). The six main factors are as follows: (1) materials procurement measures (MPMR); (2) materials procurement models (MPMO); (3) green building practices (GBPR); (4) legislation (LG); (5) culture and behaviour (CB); and (6) awareness (AW). The second stage comprised multivariate statistical analysis via the structural equation modelling (SEM) approach to develop an integrated framework for C&DWR, to support Egypt’s vision 2030. The results revealed that these six factors positively affect C&DWR in Egypt. Additionally, the study found that GBPR has the highest importance value of 0.293 and the highest performance rate of 92.169. However, CB has the second highest importance value of 0.238 whilst it has the lowest performance of 72.08 among the six factors. This paper proposes practical recommendations for the government and the construction sector to reduce the C&DW in support of Egypt’s Vision 2030
