"Kronos looked at a number of 250,000- to 300,000-sf opportunities within the marketplace, but felt that the campus feel that has developed for them in Chelmsford was not only attractive and functional, but affordable as well," says John Boyle, principal of Trammell Crow.

The engineering firm will be expanding into, and leasing in its entirety, Four Omni Way, which is an 82,000-sf building owned by Koll Bren Scheiber. In addition, Kronos will expand into the entire 17,000-sf third floor of 285 Billerica Rd., which is owned by Ray Kerry and Associates. The transaction is a sublease through Integral Access. Kronos is also renewing its lease on a long-term basis, at 300 Billerica Rd.--its current location--which was set to expire in September 2005. Owned by New Boston Fund, 300 Billerica Rd. is an 110,000-sf building.

The three-building campus transaction, coupled with the company's two other existing buildings here, brings their commitment to the area to five buildings totaling 425,000 sf of space, with more than 1,500 employees. This makes Kronos one of the largest employers in suburban Boston.
