Initially working for the university, SGH evaluated the concrete facade's condition. Our field work included visual surveys, hands-on sounding from suspended scaffolding, and obtaining samples and concrete cores. We performed petrographic analysis in our laboratory to determine the properties, quality, and condition of the concrete and identify internal deterioration mechanisms.
SGH collaborated with Bruner/Cott Architects on the tower's concrete facade restoration as part of a larger renovation and addition project. Highlights of our work include the following:
Designing details and writing specifications for the concrete restoration
Developing custom-matched, site-mixed concrete repair mix designs for the various types of cast-in-place and exposed aggregate precast concrete on the project
Overseeing and reviewing mockups of concrete repairs and cleaning procedures
Conducting site visits to observe construction of the concrete facade repairs and cleaning, and help maintain quality and conformance with our design documents
