As Director of Operations, Mr. Ashley oversees all design projects done in the New York office, including structures for large public agencies, medical campuses, and private developments. His projects have ranged in size from a two-level garage with just over 100 spaces to garages with more than 1,100 spaces. His background in engineering, structural design, parking consulting, and project management enables him to guide a team of consultants from different disciplines and to serve as a trusted advisor to his clients, bringing projects from the initial planning stages through approvals, detailed design of foundations, superstructures, durability elements and architecture, and through construction and testing. He is a member of the Precast Concrete Institute and the American Institute of Steel Construction.

Nicholas Frezza Assoc. AIA

Nicholas Frezza, Assoc. AIA Parking Consultant in Walker Consultants’ New York Office and Automation Technologies Leader for Walker.
Mr. Frezza has been with Walker for ten years and worked for another parking specialist firm for several years before. His projects include consulting projects to help clients solve specific design challenges, as well as project management of new structures through all phases of design and through construction. Mr. Frezza has worked in Walker’s Dubai office as well as New York; in the Dubai office he worked on development projects for new neighborhoods, integrating parking into complex larger networks of vehicular and pedestrian circulation, as well as working on underground and podium parking systems with thousands of parking spaces that he integrated into larger campus circulation and structural grids. With a background in architecture, Mr. Frezza is a key resource for code analyses, particularly as they relate to ADA parking requirements. Additionally, he has taken a strong interest in parking technologies, including space-saving automated (“robotic”) parking systems. Mr. Frezza is Walker’s leader for automated parking, providing input on projects all over the country. Mr. Frezza was named as one of the National Parking Association’s “40 Under 40” in 2018.

David Vander Wal PE

David Vander Wal, PE Senior Vice President in Walker Consultants’ New York Office
