Ballinger participates in national workplace dialogue

Ballinger principal Angela Fante, PE, LEED AP will be a panelist at the National Council of Structural Engineers Associations (NCSEA) Structural Engineering Summit in New York City on February 16. The panel discussion, titled “Flexible or Rigid? Rethinking Workplace Flexibility,” will explore the challenges and opportunities of the post-pandemic workplace.

Angela will be joined on the panel by Cervente Sudduth, PE, president of DuBois Consultants in Kansas City and Jennifer Ridd, PE, principal at JQ Engineering in Dallas. The discussion will be moderated by Marcus Freeman, PE of Magnusson Klemencic Associates in Seattle.

Angela is a member of NCSEA’s national Structural Engineering Engagement and Equity Committee, which captures and shares metrics on career advancement and work-life balance, to support engagement, equity, diversity and retention within the industry.

In 2016 Ballinger launched B::Flex, a program enabling remote work and allowing employees to customize work schedules. Established digital tools for collaborating remotely enabled Ballinger to rapidly adapt to remote work at the onset of COVID-19.

DVASE Outstanding Project Award

Ballinger won an Outstanding Project Award from the Delaware Valley Association of Structural Engineers (DVASE) at the annual Excellence in Structural Engineering Awards ceremony held May 12.

The honor was awarded to a confidential Philadelphia project with complex structural and logistical challenges.

Ballinger on the Structural Engineering Channel Podcast

Ballinger Principal and Chief Structural Engineer Angela M. Fante, PE, SECB, LEED AP was a guest on the Structural Engineering Channel, a podcast from the Engineering Management Institute. Co-hosts Mathew Picardal, PE and Alexis Clark, PE interviewed Angie about the structural engineering walking tour of St. Louis she recently developed with support from the Structural Engineering Institute (SEI). Angie researched and recorded the tour as a way to highlight and explain notable engineering achievements.

Groundbreaking Celebrated on New Children’s Hospital of Philadelphia Hospital

Children’s Hospital of Philadelphia (CHOP) held a groundbreaking celebration today for a new inpatient hospital in King of Prussia, PA. Ballinger provided architecture, interior design, MEP engineering, and structural engineering services for the 250,000 SF facility, which will significantly expand the services and offerings of CHOP’s current King of Prussia campus. During her remarks, CHOP President and CEO, Madeline Bell, described how the new location will provide convenient access to the highest quality hospital services available.

This new 6-story, 52-room inpatient facility will be the first standalone hospital in the CHOP network not located on the main Philadelphia campus. The facility was specifically designed to offer modern innovation while creating a family-friendly environment. Design features such as open and bright waiting areas, playrooms, ample parking, sun-filled spaces, child life services, and a concierge-like welcome experience bring this intent to life.

Angela Fante Presents at ASCE-RI Meeting

Ballinger Associate Principal and Chief Structural Engineer, Angela M. Fante, PE, SECB, LEED AP, co-presented a talk titled “Thinking Big: Structuring the Future of URI Engineering” with David Odeh of Odeh Engineers. The presentation was given at the monthly meeting of the American Society of Civil Engineers (ASCE) Rhode Island Section. Ballinger and Odeh are collaborating on the structural engineering of the University of Rhode Island College of Engineering. The presentation focused on the unique structural design challenges associated with the design of the building. Topics included the high capacity pile foundation system, lateral force resisting system, and the exposed-to-view steel trusses and connection detailing.

As partners on the project, Angie and David discussed the collaboration between OEI and Ballinger structural engineers and the importance of communication between the design team, construction manager, steel fabricator, and special inspectors on site.

The Pennovation Center: Q&A with Chief Structural Engineer Angela Fante

The 62,000 SF Pennovation Center is an incubator space developed by the University of Pennsylvania to foster tech start-ups.  Ballinger engineers worked hand-in-hand with design architect HWKN and architect-of-record KSS Architects to transform a former DuPont paint testing facility into a flexible laboratory and co-working office space.  Building operations and tenant occupancy started in Fall 2016 with positive reviews from the design and engineering community and the building’s occupants.

We caught up with Ballinger’s Chief Structural Engineer, Angela Fante, PE, SECB, LEED AP.

One of the building’s most striking features is the dramatic faceted glass outcrop.  Can you tell us about what went in to engineering that?

ANGELA FANTE:  Through collaboration with the architect and University, we were able to meet an incredibly complex structural challenge with an elegant solution. The addition of the north elevation ‘faceted façade’ had an immensely complex effect on the existing building frame.

It is not structured with cantilevers, a misnomer many are giving the north extension’s structure.

If not a cantilever, what is it?

AF:  Because the architectural design required maintaining the same horizontal banding depth across the existing to new addition interface, there wasn’t enough depth to accommodate the structure needed to cantilever the addition.  Instead, we broke the north elevation into seven individual existing column frame elevations. From there, we designed new diagonal ‘column props’ and horizontal floor strut/tie beams, which impose either a horizontal tension or compression on the existing frame, at different levels throughout the geometry of the façade.

The effect on the frame was a series of ‘pushes and pulls’ on the existing building structure, none of which it was originally designed for when it was constructed in 1954.  (In that era, engineers barely considered wind and earthquake loading).

 How are those “pushes and pulls” supported by the existing building frame?

AF:  Although the appearance of the geometry of the addition looks complex, the interface between the new and existing building boils down to 28 unique connection points (seven existing grid lines x four floor levels), each custom-detailed to develop and complete the load path from the new to the existing frame.  Once the tension or compression at each of the 28 nodes transfers to the existing north column line, the ‘dots’ of the load path are connected back through the structure down to the foundation.  New horizontal bracing in the plane of the floors was inserted within the existing building where required to transfer the horizontal force through the respective floor levels and then into the three vertical braced frame lines.  The vertical braced frames are strategically hidden within the exterior walls or exposed to view in the co-working areas, as part of the raw, industrial aesthetic.

At the base of the braced frames, the accumulated collection of these load terminates  in two-foot thick x 22’-long x full basement story height walls, ballasting the new structure against uplift and preventing the structure from lifting out of the ground.

It was like designing for the weight of 50 elephants pulling on the north face of the building.
