Jadwin Hall Renovation

Irwin & Leighton provided preconstruction and construction services for the phased renovation of Princeton’s Physics building, Jadwin Hall. The work encompassed ±240,000 SF of office, classroom, laboratory, and mechanical spaces. The scope included new interior finishes; an upgraded telecommunications infrastructure; a new fire protection system; replacement of the H.V.A.C.systems; installation of new energy efficient lighting; replacement of all perimeter windows; replacement of the existing electrical substation; and construction of a ±8,000 SF penthouse to house the new mechanical equipment. The building remained occupied throughout the entire construction phase.

Key Highlights:

Phased replacement of existing M.E.P. systems while maintaining service to all occupied spaces

Demo of existing mechanical penthouse and construction of a new one while maintaining the existing H.V.A.C. service

Sensitivity to dust, noise and vibration on ongoing experiments in the occupied building

Coordination of work with professors in regards to experiments, studies and exam periods
