Quandel offers rail and transit engineering services from conceptual design through preliminary and final engineering. Our design services include track alignment, roadbed, drainage, grade crossing and roadway geometrics and general civil design functions. We use Bentley Microstation V8i and Rail Track Suite for railway geometric design. We employ John Chance’s Flip 7 and Bentley’s Descartes V8i software for LIDAR data processing and extraction for topographic and digital terrain model mapping.
