“…The concepts that underlie parametric modeling were developed in the 1990s and subsequently implemented in mature commercial CAD systems, including Autodesk Inventor, Dassault CATIA, Dassault SolidWorks and Siemens NX. Today, these systems are used mainly in the mechanical engineering domain, but there is increasing adoption in the Architecture Engineering and Construction (AEC) industry too [16][17][18].…”

a b s t r a c tThe planning of large infrastructure projects such as inner-city subway tracks is a highly collaborative process in which numerous experts from different domains are involved. While performing the planning task, widely differing scales have to be taken into consideration, ranging from the kilometer scale for the general routing of the track down to the centimeter scale for the detailed design of connection points. Currently there is no technology available which supports both the collaborative as well as the multiscale aspect in an adequate manner. To fill this technological gap and better support the collaborative design and engineering activities involved with infrastructure planning, this paper introduces a new methodology which allows engineers to simultaneously manipulate a shared multi-scale tunnel model. This methodology comprises two main aspects. The first aspect is a multi-scale model for shield tunnels, which provides five different levels of detail (LoD) representing the different levels of abstraction required throughout the planning progress. The second aspect is a conceived collaboration platform, which enables simultaneous modifications of the multi-scale model by multiple users. In existing multi-scale approaches, where the individual representations are stored independently from each other, there is a high risk of creating inconsistencies, in particular in the highly dynamic collaborative planning context. To overcome this issue, the concept presented in this paper makes use of procedural modeling techniques for creating explicit dependencies between the geometric entities on the different LoDs. This results in a highly flexible, yet inherently consistent multi-scale model where the manipulation of elements on coarser LoDs results in an automated update of all dependent elements on finer LoDs. The proposed multi-scale model forms a well-suited basis for realizing the collaboration concept, which allows several experts to simultaneously manipulate a shared infrastructure model on various scales while using the different design tools they are accustomed to. The paper discusses in detail the principles and advantages of the proposed multi-scale modeling approach as well as its application in the context of collaborative tunnel design. The paper concludes with a case study of a large infrastructure project: a new inner-city subway tunnel in Munich, Germany.

Developing a 3D intelligent object model for the application of construction planning/simulation in a highway project

This study proposes a 3D intelligent object model in highway construction to electronically represent a large amount of information in highway projects based on the international standard ISO 10303. Also known as STEP (Standard for the Exchange of Product), ISO 10303 is an open standard, and has been used for data exchange in building projects of the AEC industries. Motivated by the success from the building industry, this research attempts to apply an object based intelligent model in 3D highway modeling. In order to test the feasibility of the proposed approach, a prototype was developed and tested on a highway project in Seoul, Korea with a team led by Korean Institute of Construction Technology (KICT). The proposed 3D intelligent model was applied to build a 3D model and automatically derive cost/schedule estimates from the 3D object model. To develop a 3D object model in highway road construction, this paper explores different options such as Industry Foundation Classes (IFCs) and LandXML and establish a comprehensive object model for highway structures with different components such as roads, a bridge, and a tunnel as well as topographical representations that could be used for cost/schedule estimation.

“…Such models, which are referred to as procedural models or construction history models, combine the use of dimensional and geometric constraints for defining flexible 2D sketches, with the concept of a procedural definition of complex 3D models through the subsequent use of geometric operations such as extrusion, rotation and Boolean operations (Mun et al 2003, Stiteler 2004, Pratt et al 2005, Koch & Firmenich 2011. Parametric modeling concepts have recently been applied to create highly flexible and adaptable models of infrastructure facilities, such as bridges and roadways (Ji et al 2010, Obergriesser et al 2011, Ji et al 2013. These techniques facilitate a step-wise development of the infrastructure model evolving from a coarse level of detail to the finer ones.…”

ABSTRACT:A multi-scale representation of the built environment is required to provide information with the adequate level of detail (LoD) for different use cases and objectives. This applies not only to the visualization of city and building models, but in particular to their use in the context of planning and analysis tasks. While in the field of Geographic Information Systems, the handling of multi-scale representations is well established and understood, no formal approaches for incorporating multi-scale methods exist in the field of Building Information Modeling (BIM) so far. However, these concepts are much needed to better support highly dynamic planning processes that make use of very rough information about the facility under design in the early stages and provide increasingly detailed and fine-grained information in later stages. To meet these demands, this paper presents a comprehensive concept for incorporating multi-scale representations with infrastructural building information models, with a particular focus on the representation of shield tunnels. Based on a detailed analysis of the data modeling methods used in CityGML for capturing multiscale representations and the requirements present in the context of infrastructure planning projects, we discuss potential extensions to the BIM data model Industry Foundation Classes (IFC). Particular emphasis is put on providing means for preserving the consistency of the representation across the different Levels-of-Detail (LoD). To this end we make use of a procedural geometry description which makes it possible to define explicit dependencies between geometric entities on different LoDs. The modification of an object on a coarse level consequently results in an automated update of all dependent objects on the finer levels. Finally we discuss the transformation of the IFC-based multi-scale tunnel model into a CityGML compliant tunnel representation.
