Eric Hammarberg

Associate Principal

Associate Principal

Eric Hammarberg has been surrounded by construction his entire life, the third generation of a family of contractors, and later running his own firm. He has worked many facets of construction, including masonry and carpentry, and became involved in preservation as these experiences, education and interest coalesced.

Eric’s experience spans from design and project manager for many historic restoration and preservation projects including the New York Public Library’s plaster ceiling restoration, St. Patrick’s Cathedral, the Chrysler Building, the Metropolitan Museum of Art and stabilization at Lefferts Historic House. He has extensive experience conducting condition surveys, preservation methodologies, façade evaluations and restorations, project programming, specification research and writing, and reviewing handicap, environmental and landmark rules compliance.

His expertise in preservation includes investigation, protection of historic structures adjacent to new construction, repair and restoration of historic stone and brick masonry, repairs of historic plaster and tall urban structures as well as repairs to terra cotta and various roofing materials. Prior to joining Scott Henson Architect as Associate Principal, Eric spent the last seven years as Associate Principal for WJE Engineers & Architects. Eric brings his vast knowledge of historic restoration across New York City Landmarks, structural and exterior envelope design and investigative expertise to the firm.
