The largest of the new lease agreements is a 34,659-sf commitment from San Diego-based CardioNet Inc. in the 72,000-sf Millennium III building at 227 Washington St. That takes building occupancy to 92%, according to Scott Gabrielsen, senior vice president of Philadelphia-based Binswanger, who is O'Neill's leasing representative for the complex. Scott Miller and James Kelley of the Philadelphia office of CB Richard Ellis represented CardioNet. Gabrielsen tells GlobeSt.com the rental rate at all three buildings is $28.50 per sf, plus electric. The 54,000-sf Millennium II is fully leased.

Three renewals secure 98% occupancy in the 72,000-sf Millennium I building, located at 20 Ash St. The largest of the three is by Pasadena, CA-based Jacobs Engineering Group Inc. for 20,023 sf. Brokers in the Philadelphia office of Cresa Partners represented Jacobs.

Gabrielsen was the sole broker in an 8,742-sf renewal by locally based Fast Track Systems Inc. at Millennium I. Brookfield, WI-based Hammes Co. renewed for 3,000 sf in the same building and was represented by Cushman & Wakefield of Pennsylvania. Gabrielsen says the stabilization of the center, which broke ground in 2001, demonstrates that "Conshohocken remains one of the most desirable locations in the suburbs." O'Neill has proposed a 270,000-sf Millennium IV, but has not set a date for breaking ground.
