What is a structure movement?
Structural movement is the movement of a building from its original foundations. Most buildings will experience some degree of structural movement at one point and it’s probably nothing to worry about. However, more serious movement can occur, causing cracks, sway and bulging.
What causes structures to move?
Buildings and other built structures are moving all the time, but usually these movements are so small as to be unnoticeable. Movement can be caused by defects, movement of the ground, foundation failure, decay of the building fabric, and so on.
What is differential movement of structure?
Differential movement occurs when independent structural components are adjoined at different parts of the building. These conditions can occur in roof systems at flashings, penetrations, adjoining roof areas and mechanical penthouses.
How do you monitor structural movement?
One of the most commonly used methods is crack monitoring to establish if there is ongoing movement in the building. Small metal studs are inserted either side of the cracks, and regular readings taken to ascertain whether the cracks are opening or closing. Typically, as little as 1mm movements can be detected.
How does a structural engineer check for subsidence?
The subsidence investigation usually involves accurate monitoring of any movement of the building or structure. This includes precise datum monitoring of principal fractures and, where appropriate, precision level survey monitoring of datum fixed close to the foundations of the building or structure.
