Chicago, IL – October 16, 2017 – Gilbane Building Company was selected by Hines as the general contractor for a 45,000 SF renovation and expansion at 321 North Clark in downtown Chicago.

Scope of work 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 the LL1 and LL2 levels, as well as complete elevator modernization.

Construction will start in the second quarter of 2018 after an intensive preconstruction effort and will conclude in two phases with the majority of the work in the first quarter of 2019 and the balance of the elevator modernization in the third quarter of 2019.

“We are delighted to have been selected for this high profile and challenging project and look forward to once again collaborating with our friends at Hines,” said Gary Thalheimer, Vice President/District Manager at Gilbane Building Company.
