The first of three tower cranes is up The Obama Presidential Center

I’d be lying if I said I understood who all is involved, and how they’re involved, in the construction of The Obama Presidential Center. What I do know is where you can go to learn some of that very information. First, visit Lakeside Alliance. To me, that’s sorta like your general contractor information. Next, visit Concrete Collective. That’s got your concrete contractor info.

The Concrete Collective was responsible for erecting the first of three tower cranes on the site last week. And you might be wondering just how many photos of a tower crane you need to see.

I say, about this many:

Three tower cranes permitted for Obama Presidential Center

The tower crane x3 permit.

Chicago construction, and the enthusiasts who enthuse it, needed this bit of news.

Saturday, the City of Chicago issued a permit to drill caissons for three tower cranes in Jackson Park at the Obama Presidential Center.

With only seven in the air now, three on one site, not only a rare feat in Chicago, would give us a nice jolt in the crane count.

Turner Construction is the general contractor on the Obama Center. W.E. O’Neil is the concrete contractor. Tod Williams Billie Tsien Architects — Partners is the design architect.

A groundbreaking ceremony was held on the site September 28.
