PHL Restroom Upgrade

PHL Restroom Renovations

Arora Engineers, Inc. (Arora) as a subconsultant to HNTB, provided construction inspection and administration services for  the restroom renovations project at Philadelphia International Airport (PHL) which involves the rehab of 30+ sets of passenger-facing restrooms. The intent of the Restroom Renovation Program is to improve passenger experience and customer service at the airport by providing exceptional quality restrooms and related amenity facilities to the travelling public. Key planning and design factors are convenience of location, proximity to other airport facilities, travel distances, high quality and durable finishes, ease of maintenance for building systems and custodial operations.

The core restroom facilities are considered to include male and female washrooms, and gender neutral, companion care washrooms. Ancillary functions may include art displays, janitors’ closets, storage, and other custodial function spaces. Related functions include Service Animal relief areas, lactation suites, adult changing rooms, quiet spaces (for meditation, reflection, prayer) waiting, device charging spaces and companion care spaces incorporating amenities such as adult changing.

The project was divided into three phases with about ten (10) restrooms in each phase. Arora provided Construction Management services for phases 1-4. Currently, Arora is in design on phases 5-9 under HDR, Inc.
