Schradergroup worked with Caretti Restoration and Preservation Services to investigate the condition of exterior masonry, primarily on the stone parapet/balustrade, from which pieces of stone had recently dislodged. The purpose of the investigation was to provide a written conditions assessment report that included observations and findings; conclusions about the cause(s) of deterioration and water infiltration; and recommendations for further evaluation and corrective action.
Following close visual examination of the stone parapet/balustrade, copper-lined external gutter, and conditions of specific interior walls, the team discerned multiple reasons for the deterioration of the areas in question, including:
• Long-term water infiltration issues
• Original construction/installation methodology
• Lack of expansion capability
• Roofing termination bar anchorage failure
• Lack of maintenance
• General age and weathering
Concerns about the stability and weather-integrity of the stone parapet/balustrade led the team to recommend two possible approaches for restoration: Stabilization / Repair / Maintenance, or Removal / Reconstruction. Suggestions for both approaches were presented to the University in a Conditions Assessment Report for evaluation based on the University’s budget, goals for physical appearance, and level of expectation for future performance.
