Urban Spelunking: Yerkes Observatory

This week, Yerkes Observatory was featured in Urban Spelunking by It has been an honor for Pierce Engineers to work on this magnificent structure, Yerkes Observatory. It has truly been a pleasure working with the Yerkes staff, Abacus Architects, Inc., Marion Restoration and all the other designers and contractors who value the preservation of Yerkes Observatory.

Our work will continue over the next few years but we are looking forward to seeing this building come alive as they reopen to the public in 2022!
