CONSIDERING that the Contracting Parties wish to stabilize employment in the pipeline sector in the construction sector and to agree on hourly wages, social benefits and conditions of employment. THEREFORE, THIS AGREEMENT CERTIFIES THAT, taking into account the premises and reciprocal agreements contained therein, the employer and the Union agree as follows: ARTICLE I SCOPE AND DEFINITIONS THIS AGREEMENT applies to the construction, installation, processing, overhaul, reception, entrenchment, removal, removal, dual link and/or service agreement for Canada. 1.4 The employer acknowledges that the work excluded in point 1.3 above is covered by other agreements and agrees to be bound by the union agreement in force on such work. 1.5 Appendix 2 is a voluntary agreement in which the individual employer and the trade union, which are both parties to this Agreement, each have the opportunity to sign an acceptance of Annex 2, which is annexed to and forms part of this point, which separates transmission lines or transverse and secondary lines with increased pressure from low-pressure distribution systems. In the case of a measuring station or connection to a gas pipeline, the construction of all pipelines extends to the point where the low-pressure distribution systems of the transverse and secondary pipes take off at higher pressure. This definition must be interpreted as falling within the definition of distribution work as it appears therein. piping; 1.2.15 Storage maintenance; 1.2.16 Underwater work; 1.2.17 Piping supports; 1.2.18 Prefabrication; 1.2.19 Initial assignment; 1.2.20 high-impact methods; 1.2.21 Welding quality control; 1.2.22 Small projects. . . .
