Madison Concrete Construction topped off the 29th floor of the 3601 Market St. project on which it had been working and beat its contract schedule by more than a month.
The 29th was slated for completion by Dec. 18 this year, but it was finished on Nov. 13.
Madison achieved a three-day cycle on the typical floors. 3601 Market St., a 28-story Class AA mixed-use building located on the 17-acre University City Science Center campus, is known as the nation’s oldest and largest urban research park. For more about this project, click here.
