Brian Hadfield P.E., F.P.E., LEED AP, WELL AP

Brian first began working with his mentor, a senior member of the Alvine team at the time, as a high school student to identify a career path that combined his love of math, science, and problem-solving. John explained how engineering and mechanical systems design could allow Brian to use his strengths to create positive solutions for buildings. That guidance led Brian to an internship at Alvine Engineering.

His hands-on internship experience prepared Brian for more complex projects. Early in his career, he was given the opportunity to design mechanical systems for 300 North LaSalle, a complex high-rise in Chicago, IL. Although he has worked on many successful projects since, Brian still uses the same approaches he learned from 300 North LaSalle as a foundation for his designs today. From designing LEED-certified buildings to his expertise in providing a healthier indoor environment as a WELL Accredited Professional, Brian pushes the boundaries of mechanical and fire protection engineering systems.

As an industry leader, Brian continues to see the value in the growing trend of integrative design across architecture, construction, and engineering. Whether it is sustainability, healthy buildings, or a lower life cycle cost, integrating teams at the beginning of a project is just one of many ways Brian guides project teams in working seamlessly together to achieve the owner’s goal.
