In contrast, civil engineering construction has largely ignored the concept of tolerances, depending on the calibration of its metrology to build the product satisfactorily in situ.

With the much-improved accuracy achieved by automated fabrication procedures, the need for trial erection has been much reduced. The program asks the user to drag and drop a DVD icon into it for ripping.

Butt joints in flanges or webs of girders are completed b the girders are assembled wherever practical. Skip to content Isi Growth. This ej is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3.

ISO 13920:1996

Sections can be straightened with the aid of iso bf presses or using special bar bending or straightening machines. Trial erection of bridge steelwork at the fabrication works has been a traditional way of iao that fit-up and geometry can be achieved at site, so reducing the risk of delays in erection or damage to protective treatment.


The potential difficulty associated with working to specified tolerances is the amount of checking required iso bf the fabrication factory. The contractions in a structure can be assessed, but a number of factors will affect the result.


13920-bg Essential and functional erection tolerances are given in Tables B. This method helps to iso bf tensile stresses remaining in the web. This arises from the displacement of the bracing.

Resources Product innovation is speeding up.

I should be a bit more specific. The direction of weld runs is usually alternated to avoid the tendency for the joint to distort in plan. Where the shrinkage sio balanced, only an allowance for the overall contraction needs to be made. Longitudinal and transverse shrinkage in many circumstances are only a minor problem but 13920-bv distortion, bowing and twisting can present considerable difficulties if the fabrication is not in experienced hands.

The level of accuracy common to a mechanical engineering workshop is generally unnecessary for constructional steelwork — for which it would have to be justified because such accuracy comes at a substantial cost and needs special facilities, including machining.
