Two Presentations from DVASE 2018 Project Award Winners
The Bridget Residential Tower - Secrets of Minimizing the Sag
Presented By: Janis B. Vacca, PE, Leed, ap VP, The Harman Group
Bridge on Race, a mixed-use apartment complex at 205 Race Street in Philadelphia's Old City, is an 18-story, 180,000 square foot, 146-unit residential building containing 10% affordable housing units and 14,000 square feet of street-level retail space.
Challenges for the structure included a wildly erratic column grid, significant slab cantilevers (up to 15'-0") and a large 5'-0" deep transfer beam at the 8th floor that cantilevered out 18'-0" to support the building above. Short and long erm structural deflections were key for placing the fašade.
A filigree concrete system was selected due to its cost effectiveness and reduction in the weight of the structure thus minimizing deflection.
Keast & Hood Longwood Gardens Main Fountain Restoration
Presented by: Brian D. Wentz, PE, CDT, Director of Historic Preservation Associate
The Main Fountain Garden at Longwood Gardens provides visitors with a display experience unlike anywhere else in the world thanks to the enduring vision of the du Pont family and the undertaking of a major restoration project to revitalize the feature five acre site. Originally designed by Pierre S. du Pont to contain the most technologically advanced engineering of the time, the Main Fountain Garden once again employs cutting edge technology comprised of new fountain lighting, jets, and fire elements.
Keast & Hood was retained for structural design as part of the massive renovation and restoration of the central, open-air fountain. Structural scope includes support for updated pumping and lighting infrastructure, a reinforced concrete service structure that extends two stories below grade, a new grotto, and a grand stair and terrace at the west end of the garden. Incorporated into the new design are historic retaining walls which engineers assisted in preserving and restoring. The extensive project scope also includes underpinning and renovation of the historic pump house for display use. The complex project required frequent coordination between the designer, engineers, and stone restoration contractor - resulting in one of the most widely anticipated Grand Re-openings.
