A BIM Enabled Blockchain Based Construction Vendor Selection System

Abstract

With growing complexity of construction projects, the industry is evolving on day-to-day basis. Each aspect of the industry has been influenced by this complexity. One of these aspects is supply of materials for construction projects. Unavailability of materials has been quite a reason for impediment in the construction process. To ensure availability of materials at construction site it is necessary to choose appropriate vendor for supply of materials. Growing diversity has led to have a chunk of vendors across the globe to supply construction materials. Moreover, fragmented nature of construction process has also been a cause for inappropriate selection of vendor. This study aims to develop a framework for selection of a construction vendor with a collaborative effort. Thus, the framework is devised using the integration of BIM and Blockchain technique. The integration of these both platforms ensure the provenance and collaboration of teams to opt a vendor. Moreover, this framework increases meritocracy and induce trust among the parties which ultimately would enhance the progress of a construction project at the execution phase.
