That was after the Sept. 11, 2001 terrorist attacks on the US forced a redesign of the project (See: Hyatt Center Design Makes for Happy Campers.) , as well as some second thoughts on proceeding at all. "Penny came back and said, 'I'm not willing to abandon this'," Pritzker says.

As Bovis Lend Lease crews worked in the background, the $427-million project moved ahead Thursday with a ceremonial groundbreaking at the site before developers and anchor tenants moved indoors to UBS Tower, ironically co-developed by The John Buck Co., which is building a similar-sized structure across Monroe Street at 111 S. Wacker Dr.

Signatures from Goldman Sachs officials did heavy lifting in their own right, as it gave the 1.7-million-sf project three office tenants committed to 945,000 sf. Law firm Mayer, Brown, Rowe & Maw has signed on for 450,000 sf, Hyatt Corp. and affiliated companies staked out 315,000 sf while Goldman, Sachs & Co. is leasing 180,000 sf in a building expected to be ready for occupancy in late 2004. Leasing broker JF McKinney & Associates, Ltd. is shopping the remaining 400,000 sf of office space.

Penny Pritzker, who heads Pritzker Realty Group, LC, tells GlobeSt.com is negotiating with multiple lenders on financing for the project.

"Frankly, without the three organizations, this building wouldn't happen," Pritzker says. "It was really a three-way agreement that we needed to occur all on the same day, at the same time. It was really quite an undertaking and accomplishment for all three organizations."

Likening it to a large family with divergent views on where to dine out, Pritzker explains the decision-making processes included internal talks within all three organizations.

"It's hard enough to get two people to agree on a set of 150 criteria, let alone three people," Pritzker tells GlobeSt.com. "But you're not dealing with just three people. You're dealing with three organizations."

Without two other anchors to go in with Hyatt Corp., Pritzker was unwilling to recommend proceeding with the project to her family, she says. "I think the unusual part of this was to get all three parties to the finish line at the same time," she says.
