Project Description

    BEC performed design review for the renovation of the Johns Hopkins University Macauley Hall building. The existing building is a four-story, 37,000 square foot classroom building constructed in the 1960s.  The existing structure consists of cast in place concrete and masonry mass walls with a steeply sloped slate shingle roof assembly. The building was gutted for renovation and new work included masonry repairs, replacement of wall windows and selected roof and built-in gutter repairs. 

    Design review consisted of review of construction drawings, specifications, and submittals in which BEC prepared a report identifying design discrepancies and recommendations to overcome weaknesses in the transitional details and development of hybrid flashing membrane and metal flashing details at the existing window openings. During construction, BEC attended pre-installation meetings for the building envelope trades to discuss best-practices, materials, installation methods, and quality control. BEC provided part-time Quality Assurance for the building envelope systems during construction to inspect for compliance with Contract Documents including: waterproofing, weather barriers, masonry, slate roofing, thermal insulation and wood windows.  Upon completion of each site visit, BEC prepared daily reports of our findings with recommendations for remediation of observed deficiencies. 

    BEC also performed water infiltration testing in general accordance with AAMA 502 field chamber method for the new wood windows.
