For the McCabe Library in Swarthmore College, CVM completed a comprehensive assessment of the building envelope to evaluate existing conditions and identify sources of water infiltration and deterioration. Based on the findings, a targeted scope of repairs and upgrades was developed and implemented to improve long-term performance and durability. At the Rare Books Library, the deteriorated mechanical screen wall framing and tile roofing system were removed to eliminate roof penetrations and avoid extensive structural repairs. The low-slope roofing system beneath the mechanical pad and adjacent to the roof access door was replaced, and a new concealed drainage plane stucco system was installed at the existing mechanical room walls. The projected masonry bays were capped with a new flat-seam metal roofing system, regleted into the existing masonry while retaining the concealed cap flashing. Windows within the projected masonry bays were replaced with new low-profile, thermally broken frames with insulated glazing units. Four damaged roof-level skylights at the southwest corner of the building were also replaced. At the entrance balcony, the existing waterproofing and concrete topping slab were removed and replaced with a new system designed to maintain a reduced height below the door threshold. Site drainage improvements were implemented at the northeast corner of the building in coordination with a conceptual drainage plan prepared by Gilmore & Associates. In addition, negative-side waterproofing repairs were performed at leaking subgrade utility wall penetrations. Collectively, these improvements addressed critical enclosure deficiencies while extending the service life and performance of the building envelope.
