GW 381 Technical Rule - Standard 05/2015
39,92 €*
For the purposes of this Standard GW 381, the term minimum requirements implies that further requirements can ensue from technical rules and legal provisions and/or that the ordering party may stipulate further requirements, in particular in the presence of special features or needs for protection or other constraints. The optional criteria shall, without claiming to be exhaustive, be considered guidance for the ordering party who shall decide on the need for further requirements. If a company consists of several units, this technical rule applies to the units in charge of underground construction and, without exception, to independent subsidiaries as well. A subsidiary shall be assumed to be independent if, in effect, it actually controls most operations and/or if the head office of the company is unable to provide the supervision of the staff and the construction sites as required.
