Lake Anne of Reston Condominiums, Heron House
Heron House, constructed in the mid-1960s, was the first residential building constructed in Lake Anna Village Center. The building comprises forty-six condominiums with concrete balconies. In 2002, the condominium association replaced the original steel-framed windows with aluminum fixed-framed and casement windows and undertook concrete repairs at window surrounds. Following this work, unit owners reported water leakage around windows openings. SGH investigated the cause of leakage at the fifteen-story, cast-in-place concrete structure.
Highlights of SGH’s work on this project include the following:
- Conducted a visual survey and water testing
- Made observations of concealed conditions at exploratory openings
- Identified leakage paths and deficiencies with the in-place window assemblies
- Recommended removal and reinstallation of the existing windows
- Designed repairs that included new window head, jamb, and still flashings
- Prepared construction drawings and specifications for remedial work
- Provided construction administration services to observe initial construction progress and compare as-built construction with the contract documents
- Provided litigation support
