The McDonald’s HQ in the West Loop neighborhood of Chicago.

Along with construction progress at the new McDonald’s Corporation Headquarters in the West Loop comes signage for available retail space, which Sterling Bay has dubbed @1045. An homage to its north frontage at 1045 West Randolph Street, @1045 is 48,000 square feet of ground-floor space, divisible to 2,000-square-foot parcels.

But enough of the real estate talk. What matters here is that McHugh Construction continues to push off the ground and into the sky. The @1045 signage is a nice touch, but construction is the real attraction.
