If you have a problem with an existing building, including signs of subsidence such as movement or cracking of walls or sagging of ceiling or roofline, or other structural issues you may need a structural engineer to carry out an inspection.
A Structural Engineer is likely to be a member of the IStructE (Institution of Structural Engineers)or a member of the ICE (Institution of Civil Engineers) and will have after his or her name the letters MIStructE, FIStructE, MICE or FICE. Structural Engineers with these letters after their names are known as Chartered Engineers. It is generally recommended that you engage the services of a Chartered Engineer rather than an Engineer who is not chartered but it should be noted that there are some Engineers with considerable experience who are not chartered. The choice is yours.
