BIM BASED PERFORMANCE IMPROVEMENT IN CONSTRUCTION MANAGEMENT BY PREFABRICATION

Abstract

Big changes don’t come easy for something as large as the construction industry, and when 
they do happen, they don’t happen all at once industry wide. Change occurs project by 
project, and company by company. BIM is currently making it more possible or feasible to 
do, but the real driver will be owners seeing examples from elsewhere in the world and 
starting to demand it for their projects. While projects of almost any size can benefit from 
prefabrication, it has perhaps the greatest impact in larger, more complex projects. These 
projects are often managed by a larger general contractor or construction manager, who will 
prefabricate mechanical, electrical, and plumbing equipment, which can be delivered to the 
jobsite and installed by smaller trade subcontractors exactly when needed. Building 
Information Modeling ―BIM‖ is becoming a better known established collaboration process 
in the construction industry. Owners are increasingly requiring BIM services from 
construction managers, architects and engineering firms. Many construction firms are now 
investing in ―BIM‖ technologies during bidding, preconstruction, construction and post 
construction. The goal of this research is to understand the uses and benefits of BIM for 
construction managers and examine the impacts of prefabrication in BIM for a specific 
residential case study. Almost for results we must show the ranges of saving in different 
stages of construction by prefabricated elements and also using BIM tools.
