Building a Concrete High-rise without Structural Steel

Brief 

Crews have begun placing concrete for The Couture tower, a 44-story high-rise building under construction in Milwaukee. The building will not have structural steel.

Insight

Construction of The Couture tower in downtown Milwaukee is in full stride and on schedule, according to the developer and general contractor.

Crews recently reached the bottom of the hole they were digging, and are continuing to remove sediment. That work is happening alongside pile driving and some concrete pouring, said Jeff Kremel, site superintendent with Madison-based J.H. Findorff & Son Inc.

Work is generally moving from east to west. Site work began in May.

The Couture is a roughly $190 million, 44-story high-rise under construction at 909 E. Michigan St. near the downtown Milwaukee lakefront. Once built, it will contain 322 residential units, 42,000 square feet of commercial space, a transit center and public park space.

Rick Barrett, The Couture developer founder and chief executive officer of Milwaukee-based Barrett Lo Visionary Development, said the project is on schedule to finish in 2023.

Piles are being driven on the eastern end of the project site, where the hole has been dug. More dirt is coming out on the western end. Kremel said about 43,000 cubic yards of material has been hauled from the site. That puts crews beyond the halfway point of the 72,000 cubic yards ultimately to be removed. Crews haul about 100 loads of material per day off the site.

A total of 192 piles will be placed in the ground, about 110 feet below grade. Each pile will have a capacity of 400 tons. Pile driving is slated for completion in January, Kremel said. There will be a few tests of the piles’ load capacity starting next week. Each test costs $50,000, Barrett said.

Following the pile driving work, crews will pour concrete in sections. They will pour the foundation and build up from there. Except in extreme cold, they will be able to pour throughout the winter.Kremel said there will be two crews doing concrete work. One will focus on the parking structure, and the other on the tower itself.
