Listen now
Description
In this episode, we talk with Logan Mullaney, president of InQuik USA, about the journey of InQuik from Australia to the USA and the development of their innovative bridge construction system. He also discusses the challenges faced in commercializing the system and the importance of academic research in improving and validating technology. ***The video version of this episode can be viewed here.*** Engineering Quotes: Here Are Some of the Questions We Ask Logan: What is InQuik, and how does it differ from traditional bridge-building methods? What were the major challenges you encountered in developing and commercializing the bridge system? How do you adapt to varying geographic and environmental conditions? Can you share details about your research projects and how they've shaped the evolution of the InQuik Bridge system? How does the InQuik Bridge system impact structural engineering practices, considering collaboration with jurisdictions, test reports, and special detailing? What advice do you have for aspiring structural engineers or future contractors aiming to make a mark in the field of structural engineering or bridge construction? Here Are Some of the Key Points Discussed About Exploring the World of Innovation in Bridge Construction: InQuik transforms bridge construction with its lightweight prefab components, simplifying installation for local workers. Weighing only 9,000 pounds for a 40-foot unit, it streamlines the process, providing ready-made abutments, bent caps, deck units, and more for efficient and reliable bridge building. Introducing a new product in structural engineering is tough due to skepticism. For a reinforced concrete bridge system, familiarity helps. Engineers prefer proven tech, making it a challenge to be the first to adopt it. Initial resistance can turn into an endorsement with successful use. The lesson is that patience, transparency, and proof are crucial for acceptance in a traditional industry. The bridge system's design is versatile, catering to 95% of scenarios without constant adjustments. It adapts to diverse conditions, from load capacities to seismic requirements. In seismic areas, reliance on integral abutment moment capacity is avoided to prevent structural issues. The streamlined design uses the same deck unit for various structures, simplifying foundation considerations. While open to tweaks, the engineers follow a one-size-fits-most philosophy in tackling bridge design complexities. Academic research played a crucial role in understanding their innovative system. They explored misconceptions like leaving formwork in place to slow curing and strengthen the concrete over time. The research addressed concerns about fatigue and welding, debunking worries about long-term design life. Thorough testing, engagement with different codes, and advocating for revisions solidified their success. Independent academic research, more impactful than consultant reports, not only validated but improved their system based on university insights. Innovation is vital for changing traditions in the industry. There's a clear openness to adopting new tech for resilient and cost-effective infrastructure. To tackle talent competition, efficient methods like modular design and automation are crucial. These speeds up project delivery, freeing up engineers for more creative tasks. The influx of enthusiastic young engineers adds excitement for the industry's future. Entering the sector with accidental innovation, the key lesson is understanding your peers and what drives them. To make an impact in engineering or construction, it's crucial to approach others strategically, considering their interests and motivations. Success comes from aligning with innovative minds in the field,
