Completion Certificates

any structural work is generally signed of by building control. supported by a srtuctural engineers report on the size of the beam required.

Please refer to counsel structural engineer as this is not normal practice

The builder himself is NOT responsable for providing a completion certificate , as mentioned from another answer , IF your job was done through the correct channels ? You should of had inspections from the local building vontrol to inspect vital stages of the build The dimentions of the steels should of been calculated by a structual engineer and followed It is also so important that the steel is suported on concrete padstones and has the required amount of bearing on either end And also the structure of the wall below the padstones needs to be solid, sound and structually safe And then it will only be your local council building control officer that needs to inspect the work and get the cometion certificate for you

Works should be inspected by building control as works progressed and a final inspection on completion if any electrical works carried out then a minor works electrical certificate needs submitting to b/c
