Contractors are required to be licensed, obtain permits, conform to structural plans, or otherwise comply with the rules of the profession of constructing and maintaining our built environment. When these rules are not followed, corners are cut, low-quality work is provided, or any other related issues arise, a structural or civil engineer is often called upon to investigate the resulting defects. Construction defects can result in immediate or potentially unsafe conditions, low-quality buildings, deterioration, or other unacceptable results. Marcor has investigated and provided expert opinions on multiple civil and structural construction defects. His opinions have been used to identify unsafe conditions, determine the extent and full implications of the defects, and ultimately find solutions to correct them.

The Federal Emergency Management Agency (FEMA) provides maps to determine flood risk to a property. Insurance companies use these maps to determine flood risk potential to properties they are insuring. However, the true flood risk to a property may be misinterpreted. Marcor was involved in a study where the depth of potential floodwater had been estimated at 2 feet at a property. He and a team of engineers performed detailed investigations of the 100-year storm and created models of the adjacent creek based on Light Detection and Ranging (LiDAR) surveys, ground surveys, drainage maps, and hydrologic and hydraulic calculations. His team found the true flood risk to the property to be less than an inch.
