Program / Project Management

Major rail and transit corridor development projects or new service startups are often complex, multi-year efforts that require coordination and integration among several stakeholders. Quandel’s management team is skillful in dealing with the limited resources and inherent uncertainties in programming capital projects and providing oversight of the project budget, consultant activities and project development process. We can prepare project management plans, design criteria, concept plans, project schedules and service plans in order to accelerate early project programming. Quandel coordinates with the stakeholders to manage grants, provide quality assurance, ensure regulatory compliance and enforce a safety culture among all parties involved in the project.


Quandel’s experience spans all phases of rail corridor planning, from early feasibility studies through the environmental clearance process. Whether a commuter rail service startup, an existing service line extension, or development of high speed and intercity passenger rail corridor, we help our clients advance their projects through the planning phase, guiding our clients to make the decisions necessary to achieve the ultimate goal of service implementation.


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.


A key component of many Quandel projects is an operational analysis of combined passenger and freight traffic in a shared rail corridor. Where the corridor includes multiple tracks, crossing traffic, frequently scheduled passenger service, dense freight operations and high speed passenger service, a sophisticated simulation model is required to evaluate capacity and optimize operations in the corridor. Quandel uses Berkley Simulation Software’s Rail Traffic Controller for such applications.

Construction Management

Quandel’s construction management and inspection team offers exceptional skills and experience for railroad infrastructure projects constructed within active railroad corridors. Our staff are trained in railroad roadway worker safety procedures as prescribed in 49 CFR Part 214. Our knowledge of track design parameters, freight and passenger railroad construction specifications, track safety standards and railroad construction equipment and procedures makes us a valuable partner in ensuring contractor performance in any railroad construction project. In addition, we bring the planning and program management skills to ensure that the project is completed according to the specifications and within scheduled time and budget to the client’s satisfaction. Our diverse experience can help in identifying potential risks and provide an early warning should the project encounter unforeseen difficulties or unplanned events. Similarly, we can provide creative solutions to resolve field problems and move the project forward to complete the construction activities and restore service.
