An Investigation on Success Factors for Scan to BIM Process

Abstract

The operations and maintenance spent about 90% of the total life cycle cost of a building. The saving in these tasks could result in a huge saving of time and cost. Since the utilization phase starts after completion of the construction, this phase is significantly affected by the construction phase. One of the most recent technologies which were introduced into the construction industry in last decade was Building Information Modeling (BIM). Beneficial use of BIM by construction practitioners encouraged the Facility Management (FM) organizations to achieve benefit from this beneficial technology. In order to gain benefit from using BIM within FM, it is essential to create the 3D model of the existing buildings. The new technologies in laser scanning have been used to overcome this barrier. For this reason, a process called Scan to BIM was established to create an accurate 3D model of the buildings using the laser scanning technologies. In recent years, many types of research were done to find the methods for converting the captured data from laser scanning machines (so called point cloud) into BIM model. However, the whole Scan to BIM process has not been studied yet. The aim of this study is to investigate this process and find out which factors should be considered in order to perform the Scan to BIM process successfully. For this reason, a comprehensive review of the literature was done through the 75 research papers from different databases. The total amount of 28 factor was found. The findings of the literature review were tested by two experiments include an HVAC plant building and an office building. Based on the experiments, three additional factors were found. The findings are concluded into four main categories to help the managers for successful completion of the Scan to BIM process.
