Owner's Representative—New York, New York


Tides is a nonprofit organization that works at the heart of today's most critical issues, supporting programs that are core to our country's nonprofit infrastructure and social change movements.Tides actively promotes change toward broadly shared economic opportunity and the opportunity to live in a healthy and sustainable environment. Founded in 1976, Tides offers an array of services that amplify the efforts of forward-thinking philanthropists, foundations, activists and organizations to make the world a better place.

Part of Tides' initiatives is providing quality work space to other nonprofits working for social change, helping them build up presence in prominent locations. Jonathan Rose Companies' owner's representative practice was retained by Tides to manage the design and construction of a fit-out of their 10,000 s.f. space in the old JP Morgan Building located at 55 Exchange Place, across from the New York Stock Exchange. This fast-track project has taken nine months to design and construct. The team put together by Jonathan Rose Companies has been successfully collaborating to deliver the project on time and on budget. This project was part of Tides' Thoreau Center for Sustainability, a 40,000 s.f. green multi-tenant nonprofit center located at 55 Exchange Place. 

The project features seven training labs designed to serve as interactive adult education facilities, two spacious offices, a lounge room and all new MEP systems. To emphasize Tides' commitment to sustainability, the project was designed to LEED Silver standards. Recycled building materials and finishes, non-toxic paints, water saving plumbing fixtures and energy efficient mechanical systems are among the green design features on this project.
