Abstract
Ministry of Land, Infrastructure, Transport and Tourism (MLIT) announced Construction Information Modeling/Management (CIM) initiative and has set up a series of pilot projects to verify its value and applicability to the industry since 2012. CIM has been well recognized since its introduction. The goal of CIM introduction is to achieve further productivity gain and improvement of quality and efficiency by integrating different types of information through entire project lifecycle from design to operation and maintenance, leveraging intensive use of ICT. Current CIM research and application to pilot projects tends to just create 3D model based on a set of 2D drawings. Not much research has been seem for leveraging product models using attribute data. This paper aims to develop a prototype of 3D models of the steel bridge and substructure that equipped defined data structure of MLIT's quantity, output the MLIT's quantity calculation result from 3D Models and verified its effectiveness.
