The inspection of a building's structure by a structural engineer aims to determine the cause of a visible structural deficiency. For example, to determine the cause of a floor sagging , the engineer must measure the sagging by taking a level reading using a laser device to determine the extent and location of the sagging.
In simpler cases, the engineer may drill exploratory holes in the walls and/or ceiling to check the structural elements supporting the sagging floor. In more complicated cases, the engineer may ask the homeowner to hire a contractor to drill exploratory holes according to the structural engineer's instructions.
A structural inspection may be carried out as part of a hidden defect case , to determine the current condition of the house's wooden structure , or to perform repairs, modifications, or structural reinforcement, such as when removing load-bearing walls. Another example is when determining whether to renovate or demolish the building.
Municipalities often request an immediate inspection of the masonry structure or walls when the city inspector detects deficiencies that could be dangerous to the public, such as mechanical detachments in the bricks. The city may also request an inspection of the integrity of the structure and foundation walls if a building has been burned.
The structural engineer conducts an on-site inspection and prepares a letter or report containing their observations and recommendations. The client may also request that the engineer take measurements to perform calculations and create plans for reinforcing or replacing the structure.
