ST. PETER'S EPISCOPAL CHURCH TOWER ASSESSMENT

CLIENT

Committee for the Preservation of Historic St. Peter’s Episcopal Church


LOCATION
Philadelphia, Pennsylvania

STRUCTURE
The 18th century masonry church tower is capped with a wood-shingled steeple and a gold leaf cross.  The interior of the tower is composed of seven levels and houses the organ blower and the bells.  There is a built-in ladder on the seventh level that provides access to the portholes inside the shingled steeple.

CHALLENGE

The brick structure of the tower was showing signs of instability and required remediation efforts that would not alter the historic masonry.  The tower required structural tie rods, as well as masonry, wood shingle, and window repairs.

SCOPE OF SERVICE
  • Inspect and report on the conditions existing in 2001 to allow planning and fundraising efforts to commence.
  • Design stabilization work with minimal impact on the historic masonry.
  • Provide construction documents and management for the tower restoration project in 2007-2008.
SOLUTION
  • Recommended the installation of a tie-rod system on two interior levels of the tower to pull the four walls back into line.
  • Provided cleaning methods and pointing mortar specifications needed to remove salt efflorescence and to protect the tower from moisture infiltration on both the interior and exterior walls.
  • Documented the large-scale windows and provided construction documents and management for the restoration and repainting of the wood fenestration.
HISTORIC STATUS
Designated a National Historic Landmark.
