The specifications are not automatically supplied to contractors, engineering consultants or suppliers. Suppliers receive the relevant specification(s) at the time of a request for a quotation and/or order letter. For ongoing projects, Gasunie determines which documents are applicable and makes this known to the contractors and engineering consultants in the application documents. Contractors and engineering consultants should send a written request for the documents if they are not in their possession. When subcontractors are being used, the contractor is responsable for requesting the necessary documents.
The GTS index describes how to apply for a Gasunie Technical Standard document. Only those that are currently applicable shall be supplied.
