The Pennsylvania Turnpike Commission was looking for environmental engineering services for its facilities statewide, including 62 interchanges, 21 maintenance facilities, 17 service plazas, 8 police stations, 5 tunnels, and multiple administrative and operation buildings.

RETTEW’s staff experience in wastewater and environmental engineering, along with our strategic office locations to provide on-site services, led to selection by the Commission to provide services in an open-end contract. Our team of experts conducted pump station inspections, wastewater treatment plant inspections, water and wastewater system design, and construction observation. RETTEW provided quick response to each task order and integrated services such as field inspections, surveying, and management of environmental media in house.
