University of Virginia, Clemons Library & Harrison/Small Building

SGH investigated leakage at the Clemons Library’s tiered terraces, the interface between the two buildings, and into the rare book storage area below the plaza. We also investigated condensation and apparent biological growth at skylights in the plaza. Highlights of our work include the following:

• Surveying the building, documenting concealed conditions at exploratory openings, and performing air/water infiltration testing to identify leakage paths
• Identifying discontinuities in the waterproofing system and recommending repair options for the university’s consideration
• Coordinating with the university and developing a phased repair approach that aligned with their operations
• Designing and administering repairs, including:
  • Replacing the terrace and exterior stairway waterproofing at Clemons Library and integrating it with the surrounding rising walls/parapets
  • Reconstructing waterproofing, expansion joint flashings, and drainage at the areaway between the two libraries
  • Improving thermal performance and resistance to air infiltration at the skylights and interior light wells to address seasonal condensation
