The Mills Building

SGH collaborated with Gensler, the architect of record, and the project team on the building enclosure design that included:

• Replacing existing windows and coating the architectural precast concrete surrounds
• Overcladding portions of the precast concrete wall panels with a combination of terra cotta and metal panel cladding and attaching the new cladding panels to the existing architectural precast
• Expanding the ground-level retail space by adding new curtain wall to enclose the existing arcade and adding a new entrance canopy
• Enclosing the new three-story vertical addition with unitized curtain wall and metal panels and low-slope roofing
• Providing new roofing and vegetative assemblies at the rooftop amenity terraces

Highlights of our work include:

• Reviewing the proposed design for the building enclosure and helping develop details to integrate the various systems
• Analyzing the attachment of the precast wall panels to the base building structure and developing a testing protocol to evaluate the feasibility of anchoring the new cladding to the existing panels
• Evaluating new roofing assemblies, including amenity roof landscaping
• Providing construction phase services, including reviewing submittals and substitution requests, witnessing performance testing of in situ curtain wall and terrace waterproofing assemblies, and helping the project team address field conditions
