Yes, structural engineers regularly assess existing and historic buildings. This may include evaluating load-bearing elements, investigating cracks or movement, assessing foundations, or advising on alterations and re-use. Historic structures often require sensitive engineering solutions that respect original materials while meeting modern safety standards. Structural assessments help identify defects, understand structural behaviour and determine appropriate repair or strengthening strategies. These assessments are essential for refurbishments, change-of-use projects and developments involving retained structures.
