Integration of Conformance Checking and Estimation of Prestressed Concrete Hollow Slab Bridges by a Product Model

Abstract

[Abstract] In order to enable interoperability of various systems for analysis, design, estimation, etc., in the lifecycle of bridges, three dimensional product models are necessary. In this research, first, we proposed an application-independent 3D product model for prestressed concrete (PC) hollow slab bridges, and we implemented it by using Extensible Markup Language (XML). Then, we developed conformance checking and estimation systems for PC hollow slab bridges and integrated these two systems with a 3D CAD system by the 3D product model. We investigated the improvement of the efficiency by applying this system to a simple PC hollow slab bridge.
