Abbott Laboratories, Buildings AP6A and AP6B

SGH assessed the condition of the roofs and facades, primarily constructed with a custom brick veneer and concrete masonry unit backup walls, full-height strips of aluminum-framed window assemblies, and exposed aggregate precast accent elements. Highlights of our work include:

• Reviewing existing documents to understand the existing construction
• Performing interior and exterior surveys and making observations at exploratory openings to document concealed conditions
• Using infrared imaging to visually identify areas of potential air or water leakage
• Conducting water and smoke testing to identify water and air leakage paths
• Analyzing thermal performance of several existing conditions and repair options to assess the potential benefits
• Recommending short- and long-term repairs and providing cost estimates to help Abbott Laboratories plan and budget for this work
