Perception of Contractors about Different Sources of Coarse Aggregates Used in Selected Building Construction Projects with in Kathmandu Valley

Abstract

Purpose: The study was focused to find out the perception of contractors about different Sources of Coarse Aggregates used in Selected Building Construction Projects within Kathmandu Valley. The demand for coarse aggregate is increasing rapidly in the Kathmandu Valley for the construction of building-related structures after the Maoist revolution and the devastating earthquake of April 2015. Aggregates from different quarry sites should meet the physical requirements prescribed by the Indian Standard (IS), the Department of Urban Development and Building Construction (DUDBC), the National Building Code (NBC), the Nepal Standard (NS-297), the Standard Specifications for Road and Bridge Works (SSRBW). The perceptions of people from both sources; source 1, dissatisfaction with the sources, problems in the local community not addressed by the local government and management team were both responded to with support for the closure of the plant. The majority of respondents from source 2 were satisfied with the responses, having few complaints.
