Associate Principal


Tracy Naso specializes in the investigation and repair of reinforced concrete structures, including conventional, post-tensioned, prestressed, and antiquated systems. Her experience includes a wide variety of structures, including tunnels, parking structures, plazas, stadiums, pools, and high-rise towers. Ms. Naso also investigates failures and collapse due to storms, fire, extreme events, and structural deficiency. She is experienced with available methods of nondestructive testing and sampling to establish properties of existing structures and has developed expertise in the selection of strengthening, repair, and waterproofing methods and materials. Ms. Naso designs structural repairs for the remediation and strengthening of new and existing structures, develops construction documents, and provides construction period observation and administration services for the implementation of repair designs.
