In a request for qualifications issued this week, the organization said it is looking for firms with experience in trail planning, design and engineering, construction oversight, and project and grant management. Selected consultants will support both routine and emergency design needs, as well as project oversight for trail-related improvements.

Consultants may also be asked to assist with work tied to other Delaware & Lehigh National Heritage Corridor programs, including the National Canal Museum.

Interested firms can review the request for qualifications and submit proposals through the organization’s website. Questions must be submitted online by 4 p.m. Jan. 23, with completed qualifications due by 4 p.m. Feb. 6 for consideration.
