Daniel H. Eilbeck

Associate Principal


Daniel Eilbeck has more than twenty-five years of experience in the evaluation and repair of existing structures, ranging from concrete bridges to historic wood-framed cottages. His work has included structural engineering assessment as well as evaluation and materials conservation of historic building facades. Mr. Eilbeck has performed architectural and structural engineering evaluations of wood, steel, concrete and masonry structures, including preparation of drawings and specifications and construction administration.

Mr. Eilbeck has extensive experience with masonry facades exhibiting surface deterioration, corrosion, structural problems, and water intrusion, including evaluations of brick, stone, terra cotta, and concrete. He is also experienced in nondestructive evaluation, corrosion testing, and monitoring of concrete structures.

Mr. Eilbeck’s structural engineering work has included repair designs, seismic upgrade designs, and studies of the structural behavior of traditionally nonengineered materials and systems. His projects have received three California Preservation Design Awards and the SEAONC Award of Excellence.
