The Year in Infrastructure 2007 - (Page 66) ciVil VisualiZatiOn and simulatiOn Creative and effective approaches in the simulation and visualization processes. Projects may feature aesthetic, performance, or analytical nature visualization and simulation and use advanced techniques to virtually involve stakeholders in the planning, design, and operation of civil infrastructure. winner East London Line Project mott macdonald ltd This project will connect highbury and Islington Station on the North London Line with a connection into the Network Rail infrastructure in South London. The East and North London lines are the first two lines to form part of the London Overground franchise. On completion, the total cost of the project will be $2.75 billion. Though half of the railway infrastructure does not yet exist, Mott MacDonald used topographical surveys and current infrastructure designs to build a 3D model of the railway. The model includes 12 kilometers of railway and more than 140 signals. Because the model contains all aspects of the project that will affect the signal sighting process, the firm was able to position the signals with confidence that the location would prove correct. The model is intended for other uses as well. The 3D model enabled Mott MacDonald to quickly incorporate project design changes. For example, in the late preliminary design stage the decision was made to expand the train stabling area at New Cross Gate from 10 to 12 four-car units to 21 units and include a light maintenance and cleaning facility, all on the same parcel of land. Mott MacDonald intends to continue with the modeling process through detail design and implementation. The model may also be used as a basis for driver training and route familiarization. The modeling process highlighted the complexities of threading a 21st century railway through 19th century infrastructure. From the outset, the visualization enabled by MicroStation served a dual purpose of design and design validation to deliver more than just an assessment of signal sighting issues. The infrastructure model is now used as a tool to reach design decisions on aspects of the project ranging from passenger evacuation analysis to interdisciplinary checks and option assessments. 66 ThE YEAR IN INFRASTRUCTURE 2007
