Mary H. Darr has 25 years of structural and forensic engineering experience. She has performed hundreds of investigations and routinely assesses damage to structures caused by fire, wind, snow, impact, settlement, and corrosion. This work has included buildings constructed with conventionally reinforced concrete, prestressed and post-tensioned concrete, steel, masonry, and wood structural systems.

Ms. Darr is also well versed in the preparation of construction documents to repair damaged structures, adapt existing buildings for new uses, and for new commercial building construction. Examples of past repair projects have included drawing and specification development to address timber truss, two-way concrete slab, post-tensioned concrete slab, open-web steel joist, masonry facade, low-pressure stainless steel air piping, and foundation distress. With regard to adaptive reuse, she was responsible for leading a team of engineers to modify six existing warehouse buildings, constructed from 1920 to 1970, into new commercial and stadium occupancies as a part of the new Ford Field construction. She has designed and prepared construction documents for numerous new single and multi-story steel and wood-framed commercial structures.

Her clients have included building owners, property managers, contractors, attorneys, insurance companies, engineers, and architects.

Prior to becoming an engineer, Ms. Darr worked as a carpenters’ apprentice on highway bridge structures and a laborer for commercial building construction.
