At Ұ����Ƶapp, technical excellence extends beyond project delivery — it includes advancing the standards, practices and people that shape the construction industry. Jaclyn Ferraro, Senior Concrete Petrographer and Team Manager, and Jay Dorst, National Practice Manager – Forensics and Structural Investigations, highlight their work at Ұ����Ƶapp, the complex infrastructure projects they support and their leadership within professional organizations such as the American Concrete Institute, ASTM International and various certification programs.

Together, Jaclyn and Jay embody Ұ����Ƶapp’ commitment to technical rigor, collaboration and industry leadership — advancing not only projects, but the standards and practices that shape the built environment.

Both of you work in highly technical disciplines. How would you describe your focus at Ұ����Ƶapp?

Jaclyn Ferraro: My role centers on petrography — understanding construction materials at a microscopic level to answer real, practical questions. At Ұ����Ƶapp, I manage our petrographic laboratory services while also working nationally on forensic investigations, aggregate evaluations and condition assessments of concrete and construction materials. Whether we’re investigating issues that present themselves during construction, damage that develops over time such as chemical reactions within the concrete, or singular events such as fire damage, the objective is always the same: to provide clear information so clients can make informed decisions about their structures and materials.

Jay Dorst: My focus is broader but complementary to Jaclyn’s work. I support structural and metallurgical engineering, welding, corrosion and specialty testing — often on large, complex infrastructure and building projects. At Ұ����Ƶapp, I lead teams involved in quality assurance programs, forensic investigations, source inspections and structural testing. A core part of my role is translating highly technical findings into actionable guidance so owners, agencies and contractors can address challenges while keeping projects moving forward safely.

Much of Ұ����Ƶapp’ work involves quality assurance and independent oversight on complex infrastructure projects across the country. Are there any projects you’ve worked on that you find particularly rewarding as a professional in this industry?

Jay Dorst:
One effort that stands out involved providing independent quality assurance and oversight on a large, statewide transportation program. I led teams evaluating weld quality, prestressed concrete girder performance and fabrication conditions across multiple structures. The level of rigor required on projects like this is exceptionally high, as the work supports safety, long-term durability and confidence in major infrastructure investments.

Another impactful example was a high-rise building investigation, where our team performed independent forensic evaluations and laboratory testing to understand contributing factors related to structural performance concerns identified during construction. Projects like these highlight the importance of objective, technical oversight — particularly on fast-paced, complex projects where coordination, accountability and performance expectations are high.

Jaclyn Ferraro: Forensic concrete investigations are always impactful because they help explain what’s happening within the material and why certain behaviors or conditions develop. My work frequently involves evaluating deterioration related to freeze-thaw exposure, chemical attack, strength deficiencies or aggregate reactivity. I also support aggregate qualification and air-void system analyses for airfield paving and heavy-duty pavements.

Professional organizations and certifications play a major role in your work. Why is this involvement so important?

Jaclyn Ferraro: Professional organizations are essential to advancing quality, consistency and technical excellence in the concrete industry. I’ve been an active member of the American Concrete Institute Illinois Chapter (ACI-IL) for more than 10 years and have served on its Board of Directors since 2021. I stepped into executive leadership roles beginning in 2024 and currently serve as Chapter President.

ACI plays a vital role in developing technical resources, best practices and certification programs that influence how concrete is designed, produced, tested and evaluated. At the chapter level, we focus on providing education, professional networking and certification support for practitioners across the state, while remaining closely aligned with national and international standards.

This year’s ACI Convention in Rosemont, Illinois, was especially meaningful. Ұ����Ƶapp was a sponsor and ACI-IL was the host and sponsoring chapter. I had the opportunity to co-chair the convention and to welcome attendees during the Opening Session.

Beyond ACI, I’m deeply involved with ASTM International (the American Society for Testing and Materials). ASTM develops industry-standard specifications and test methods used to evaluate the strength, durability and performance of cement and aggregate materials. These standards provide consistency across laboratories, job sites and investigations, and are foundational to quality and repeatability in construction projects. I’m also active with the Society of Concrete Petrographers (SCP), which supports collaboration, peer learning and mentoring within this highly specialized discipline.

Supporting the next generation is one of the most rewarding aspects of this work. I’m especially proud that my Ұ����Ƶapp colleague, Alethea Muno, Petrographer II, was recently selected as an ASTM Emerging Professional — a recognition that reflects both her technical potential and Ұ����Ƶapp’ broader commitment to cultivating future industry leaders.

Jay Dorst: From an engineering and construction perspective, standards and certifications provide the framework that allows complex projects to move forward with confidence. I’ve been a member of the American Concrete Institute since 2014 and am actively involved in several technical committees that influence construction quality and safety.

I serve as a voting member of ACI Committees C680 and C681, which oversee certification programs for installers and inspectors of post‑installed anchors in concrete, and as a voting member and Vice Chair of ACI Committee 355, which focuses on anchor qualification and performance. I currently serve as Task Group Chair leading efforts to improve anchor testing in moving cracks — work that supports structural performance in seismic and dynamic conditions.

I have also been actively involved with ASTM International for more than 20 years, serving as a member of Committees E6.11 and E6.13. Throughout that time, I have contributed to and drafted multiple ASTM standards related to testing of fiber‑reinforced polymers and anchors to concrete. These standards support consistency and reliability across engineering, construction and forensic investigations.

How do your disciplines intersect when it comes to advanced expertise in safety management and risk mitigation — critical considerations when solving client challenges?

Jay Dorst: Many challenges don’t fit neatly into a single category. A structural concern may be influenced by material behavior, fabrication practices, welding quality or environmental exposure, which makes collaboration essential.

Alongside Jaclyn’s petrography laboratory, within my team, we maintain a forensic metallurgical laboratory, structural engineering support and field-testing teams that provide complementary support depending on the scope of the investigation. This approach allows us to evaluate materials, structural performance and construction practices together, helping clients understand what occurred and how those factors affect durability, performance and safety.

Jaclyn Ferraro: Exactly. Petrography often answers the “why,” while engineering answers the “so what.” At Ұ����Ƶapp, those conversations happen naturally across disciplines, allowing us to deliver more complete conclusions.

What keeps you motivated in your work at Ұ����Ƶapp?

Jaclyn Ferraro: Solving problems that matter, contributing to the profession through standards development and mentoring the next generation of materials professionals.

Jay Dorst: The combination of technical challenges and real-world impact. When our work strengthens decision-making and supports the quality and safety of the built environment, that’s incredibly rewarding.
