Faced with severe freight rail congestion in the Chicago metropolitan area, a consulting firm engaged V3 to conduct a confidential preliminary engineering and environmental study to explore alternative bypass routes. The goal was to identify viable alignments that could alleviate bottlenecks and improve regional rail service. The study required a multidisciplinary approach to evaluate complex infrastructure scenarios across multiple counties, all within an accelerated three-month timeline.

KEY CONTRIBUTIONS:

Multidisciplinary Route Evaluation
We brought together our railroad, structural, environmental, and natural resources teams to develop and assess alternative alignments, including new sidings, staging yards, modified existing yards, major river crossings, and upgraded train signaling systems with Positive Train Control.

Environmental Impact Analysis
We evaluated potential environmental impacts, including floodplain and wetland mitigation needs, and identified critical issues across the study area. We prepared plan exhibits and high-level cost estimates for each alternative to support informed decision-making.

Innovative Terrain Modeling
We overcame the challenge of limited survey data by using Google Earth’s elevation feature to model terrain and develop railroad profiles. This allowed us to refine land acquisition, earthwork, structural, and floodplain mitigation cost estimates with speed and accuracy.

Accelerated Delivery
We completed the preliminary study within a compressed three-month schedule, meeting the client’s deadline while maintaining quality and precision across all deliverables.
