City of Norwich Transportation Center

norwich, CT

AI provided design services for the Norwich Transportation Center. The Intermodal Transportation Center provides commuters access to services that strengthen the transportation connectivity of the area and grants the public better access to the Southeast Area Transit District’s (SEAT) operations. There are further plans for the project’s second phase to bring in future ferry and rail services.

The project’s scope also included telecommunications (phone and data) access control security and CCTV surveillance as well as lighting, power to equipment, and fire detection and alarm.

The facility comprised three major components. A bus terminal at grade, including multiple pickup and drop off locations for taxis, limousines, and personal vehicles as well as a bus turn around area. A three-story, ±200-car precast concrete parking structure above the bus terminal. An attached single-story administrative building for ticketing, lobby, and public restroom facilities, which are amenities newly introduced to SEAT customers by this project, was located at an intermediate level adjacent to the parking structure above the 100-year flood line.

AI was involved with planning and designing the facility’s needs. As the M/E/P engineer for the project, AI was responsible for evaluating the existing water, sanitary, and electric services for their suitability in the new facility. As a result of our analysis, upgraded water, sanitary, and electric services were designed for the site. A new electrical service for the exterior pad-mounted transformer was coordinated to be above the flood line. All electrical, mechanical, and plumbing services were located in the administrative structure to avoid flood issues.

The lighting for the parking structure and the site around the facility was designed using high-efficiency, long-life LED fixtures, making the center the first facility in the city to use LED light sources for site and parking lighting. A facility fire protection dry standpipe system was designed as well as a complete facility storm water collection system including storm and sanitary separation and related lift stations. The new administrative building design included a HVAC system with zoned control for the public area and the staff support areas as well as complete hot and cold water and sanitary waste systems for the restrooms.
