Tectonic was retained by HNTB Corporation to provide Special Inspection services for the NYCT Enhanced Station Initiative (ESI) Program on a task-order basis. The focus of the ESI program is to improve customer experience, the continued responsibility of providing a state of good repair in stations, and the development of underlying station aesthetics through construction and design innovation. The work involves the renewal and enhancement of 33 pre-selected stations located in all five boroughs. The work will include making the stations cleaner, brighter and easier to navigate, by utilizing means such as improved lighting and more intuitive wayfinding and will provide amenities such as Wi-Fi and cellular connectivity. This will involve architectural finishes (including painting and signage), structural repair and modifications, electrical (including lighting, communications and technology) and mechanical work, as well as architectural and engineering services and surveying.
