River Point tower is under construction at 444 W Lake Street by James McHugh Construction. Its associated building permit, which only comprises the base/train cover structure depicted, has an estimated project cost of $27,050,000. Photo by Bart Shore.

Here I go again not talking about urban planning on Steven Can Plan. With my Licensed Chicago Contractors & Construction Activity website I’ve ingested a lot of data from the City of Chicago’s open data portal that has a LOT to say about what’s going on.

Nearly all permits include a reasonable value that estimates the project’s cost – like $13,150,000.00 for converting Lafayette Elementary School into a performing arts high school. (All demolition permits show $1 and some permits cost over $6 billion, which we know is false.)

I recently reorganized the data (migrating from MySQL to PostgreSQL which supports the JSON datatype) to expand the ways I can extract info and I’ve sorted it by general contractor’s aggregate project value for this year.

This is a list of the 20 most active general contractors in Chicago for 2014 until May 13, 2014. I define “activity” purely by the companies’ involvement in a Chicago-based project and corresponds to that project’s estimated cost. (The data doesn’t specify a level of their involvement in a project.)

Do any names ring a bell, or surprise you?
