Gilbane Building Company Starts Construction at 321 North Clark Project Site

Gilbane Building Company is pleased to announce construction has started on the 45,000 SF renovation and expansion project at 321 North Clark in downtown Chicago.

The project, located at the highly visible intersection of Clark Street and the Chicago River, is approximately four blocks from Gilbane’s downtown office.

The complex project consists of enlarging and refurbishing the main lobby area, creation of integral retail and restaurant space, the construction of a partial mezzanine level on the south end of the building, remodel and reconfiguration of portions of two lower levels, as well as a complete elevator modernization.

“We are excited that construction is now underway and look forward to successfully delivering this complex renovation next year. It’s been a great partnership so far with our friends at Hines, Goettsch Partners, Alvine Engineering, Thornton Tomasetti, ARA and Diversified.” – Gary Thalheimer, Vice President/District Manager at Gilbane Building Company.

Much of the work will be completed in the first quarter of 2019, and the balance of the elevator modernization in the fourth quarter of 2019.
