PHILADELPHIA-Day & Zimmerman has signed a lease for 122,000 sf at 1500 Spring Garden St. The company, which provides a wide range of services, including outsourcing solutions for government and industry, will relocate its global headquarters from 1818 Market St. this summer.

The Spring Garden property is a former Smith Kline pharmaceutical plant that was acquired by locally based Amerimar Enterprises in 2000 and subsequently converted to a class A facility with redundant technological capabilities. Amerimar continues to operate the building, and Andrew Bleznak, a member of the owner-partnership, previously told the renovation exceeded $100 million.

Day & Zimmerman joins CBS3, which is the local CBS television affiliate; North American Publishing Co., and Independence Blue Cross and takes occupancy to 70%, according to Bleznak. He declined to disclose the value of the lease, but tells that Day & Zimmerman not only saves money with the move, but also “can stack space in a more flexible and efficient manner.”
