743 North Armour Street, Chicago Illinois
Architects:  Worthmann and Steinbach, 1911

Holy Innocents Church was built in 1911 and designed by Worthmann and Steinbach. Distinguishing features of the building include seven copper domed roofs (one centrally located main dome and six lesser domes), bell towers on the west facade, and stained glass windows imported from Austria and Poland.  Varied hues of red brick masonry and limestone constitute the primary building materials for the church

Klein and Hoffman, Inc. was retained by the Archdiocese of Chicago to perform an investigation of the exterior envelope.  The report identified varying degrees of deterioration.  The work scope included the replacement of all seven copper-clad domes, extensive brick repair, and replacement of the stained glass window protection.

Extensive attention to detail resulted in the replication of the copper ornament to match the original design.  The dramatic before-and-after images are attributed to the selective cleaning of the brick and limestone masonry.

One of the challenges encountered with the Church was the extensive deterioration of the steel within the bell towers.  K&H designed two innovative solutions to retain the towers.  The south tower required a partial rebuild; the north tower required the installation of a permanent interior steel structure.  All work was completed while retaining the historic bells within each tower.
