Tracy Naso

Principal and Unit Manager


Tracy Naso specializes in the investigation and repair of structures. Her emphasis is on reinforced concrete systems, including conventional, post-tensioned, prestressed, and antiquated systems. Her expertise extends to various structures, including high-rise towers, parking structures, plazas, pools, tunnels, and stadiums. Ms. Naso also investigates failures and collapses 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 repairs for the remediation, strengthening, and protection of new and existing structures, develops construction documents, and provides construction period observation and administration services for the implementation of those designs.
