Experience

Flora Calabrese is experienced in the evaluation and repair design of concrete, concrete masonry and steel structures. She specializes in the condition assessment of these structures related to serviceability and structural distress and deterioration caused by environmental factors, design issues, and/or construction factors. Ms. Calabrese has also designed and evaluated shoring for construction, designed load tests of existing structures, performed assessments and repair design for existing building structures, foundations, and facades, designed new bridges and culverts, and has performed peer reviews for new structures. This work has been performed for a number of structure types, including residential, office, parking structures, hospitals, and manufacturing and warehouse buildings, as well as bridges, tunnels, and sanitary structures.

Ms. Calabrese authored a chapter on formwork design and construction in the Construction Handbook for Bridge Temporary Works for the Federal Highway Administration. She has also coauthored a chapter in the National Park Service book Twentieth-Century Building Material: History and Conservation, and has lectured on the subject of concrete slab behavior.
