Road construction is fundamentally different to building construction, in terms of its products, the types of work and operations, and the resources used. One of the key differences from the point of view of planning and control of production flow is that roads are composed of geometrically continuous courses rather than discrete ‘products’, making work packaging difficult. Clearly defined work packages that comprise work performed on distinct products are central to lean construction methods of planning and control, such as the Last Planner System. We therefore propose a product schema which models road sections with distinct road course segments that are dynamically defined aggregations of 'roadels'. A roadel is a fine-grained vertical triangular prism object that can be dynamically aggregated with other roadels to represent a road course segment associated with a work package, a planned task, or an as-built section. The schema represents the continuous nature of road construction, and its discrete entities enable representation and computations of as-made work using the raw data obtained from machine-mounted sensors and land surveys. We describe the information schema and illustrate its use for computation and analysis of lean production flow metrics. The schema has been tested using case study data from a 25,000 m2 parking lot project, which was modeled with more than 560,000 roadels with as-made status data collected from 33 working days over a period of two months.

According to new regulations, railway employees require computer-based training before they get a driver license. Training with simulators is now a must to increase the safety and efficiency of railway transportation. In this study, a train driving simulator with full cab and motion platform, called TRENSIM, was developed for Turkish State Railways. It was realized that constructing a data model of the railway was one of the most important aspects of the project. Many modules of TRENSIM make use of this data model in real time. We developed a general railway data model, called OpenRailway, expressed in Extensible Markup Language for logical description of railway networks. OpenRailway includes a railway model, which consists of signals, railway elements (catenaries, switches, etc.), road properties, surroundings near the railway road and their parameters. OpenRailway can also be modified to be used in the development of other vehicle training simulators. Data from real trains was collected in 4 ms periods for the validation of the dynamic and visualization models (about 200 GB). It was seen that data generated by models are appropriate to the collected real data.

“…Therefore the modified parameters of the dam or cutting cross sections are transferred back to the 3D modeling system. The exchange of these parameters is facilitated by using an extended version of the LandXML format (Rebolj et al, 2008). Afterwards an update function in the add-on 'Geo2NX' updates the parameter of the 3D roadway model by interpreting the new XML file, for example when the slope angle of a dam is changed from 26.5 degree to 14.0 degree ( Figure 6).…”

This paper investigates ways to improve the integration between the geotechnical and infrastructural designing, modeling and analyzing processes. Up till now these three planning stages have been executed separate and without data exchange between each other. This separation leads to a time-consuming and expensive manual re-input of geometric and semantic data. Currently, roads are designed using a traditional approach which is based on various 2D drawings and is focused on the roadway itself. Additional geotechnical conditions such as the slope angle of the dam or the position of a retaining wall are not considered. To solve these problems, a new parametric and 3D-model based approach has been developed in the research project 'ForBAU-The virtual construction site'. This new approach is based on the traditional 2D infrastructure planning process which is extended by a new parameterized 3D modeling concept. Different open data formats such as LandXML and GroundXML allow data integration with both, a parametric Computer Aided Design (CAD) system and geomechanical engineering software. An automatic update function ensures data flow without loss of information. Use of this new approach will accelerate the infrastructure design and provide a parametric 3D-model approach which will close the gap between the geotechnical and infrastructure planning process. This paper strives to provide detailed information about this new integration concept and gives an overview on the various implementation steps.
