Accolade on Chestnut


Sansom Place East is a high-rise apartment tower for University of Pennsylvania (UPenn) graduate students. Looking to modernize the 1970s building, UPenn partnered with Greystar on a redevelopment project to improve the building enclosure and renovate interior spaces. SGH consulted on the building enclosure rehabilitation for Sansom Place East, which was rebranded as the Accolade on Chestnut and houses 473 apartment units.

On behalf of Greystar, SGH collaborated with the design team to assess the existing enclosure and evaluate proposed repairs and improvements. Highlights of our work include:

  • Performing a visual condition assessment of the exposed concrete facade and low-slope roofing
  • Helping select coating materials for the concrete facade elements and consulting on the approaches for insulating the exterior walls
  • Assisting with the roofing replacement design
  • Evaluating replacement window options and proposed detailing to integrate the new windows with the surrounding wall assemblies
  • Reviewing enclosure-related submittals to compare with the design intent
  • Sounding concrete during construction to assess the condition of existing shear walls and in situ repairs
  • Visiting the site to observe coating mockups and application, roofing installation, and window replacement
  • Helping the project team address field conditions during construction
