The building, having an estimated construction value of $30 million or about $150 per sf, is expected to break ground June 15 on a site off the County Road 46A exit of Interstate 4 in Lake Mary. The lease transaction and the ground-breaking were scheduled to be announced today.

Terms of the lease weren't disclosed by either Fiserv or Birmingham, AL-based Colonial Properties Trust, the park's developer. But office brokers familiar with the hot, suburban Lake Mary, FL submarket tell GlobeSt.com on condition of anonymity the lease should have an aggregate gross value of $46 million over at least 10 years based on a full-service rent of $23 per sf.

Kathy Lesiuk of Strictly Commercial Inc., Orlando, negotiated the lease for Fiserv CBS Worldwide, a subsidiary of Nasdaq-traded Fiserv Inc. of Brookfield, WI. Tom Green, Colonial Properties Trust senior vice president, represented the developer.
