How Can We Help?

O’Donnell & Naccarato offers four decades of award-winning structural engineering design to garage owners, developers, & operators. With over 400 garage projects, our vast experience in designing new garages provides us with an understanding of how to repair them, and our knowledge of reoccurring issues within garages has led to the improved design of new garages.

Our in-house restoration team has extensive experience with structural systems of all types and complexities. Our restoration staff holds leadership roles on several national professional organizations focusing on parking garages, assessment of concrete, and design of concrete repair. Our team utilizes this specialized knowledge and skill to investigate each garage’s unique structure.
