25/064 - Système de qualification pour la fourniture de tuyauterie en polyéthylène (PE), raccords et vannes

The objective of this QSQ is to qualify Applicants onto the Qualifications System for the manufacturing and supply of Polyethylene (PE) Pipe, Fittings and Valves for Gas Networks Ireland. The proposed supply requirements are to be divided into four (4) separate lots as detailed below: • Lot 1 (PE Pipe 90mm - 400mm) – Manufacture and supply of PE pipe for gas. • Lot 2 (PE Pipe 20mm - 63mm) – Manufacture and supply of PE pipe for gas. • Lot 3 (PE Fittings) Manufacture and/or supply of PE Fittings for gas. These include but are not limited to PE; caps, couplings, elbows, equal tees, flange adaptors, reducers, tee branch saddles, tees, tapping tees, G clamp adaptors, multi tap tees, branch saddles, bends, unequal tees and end caps. • Lot 4 (PE ball valves) – Manufacture and/or supply of PE Valves for gas. These include but not limited to valves ranging in size from small diameter 20mm to larger diameters up to 315 mm. Please note: Lots 1 and 2 relate to manufacture and supply requirements. Lots 3 and 4 relate to manufacture and/or supply requirements. The requirements for the manufacture and/or supply of pipes, fittings and valves under this Qualification System will include arrangements for delivery to various stipulated depot destinations on the island of Ireland and the ability to operate a national distribution network. Applicants should note that from time to time over the term of the Qualification System, the Contracting Entity, at its sole discretion but without altering the overall nature of the Qualification System, may modify the Qualification System to reflect changes in its requirements. Such modifications may include changes to the pipe diameter and pressure rating which may result in an increase to the pipe size, wall thickness and pipe properties or specification and the provision of services or additional supplies associated with such changes. The Contracting Entity will also seek similar changes to pipe fittings and valves. The conditions under which such an option may be exercised by the Contracting Entity will be outlined in the relevant call off competition document. The Contracting Entity also reserves the right to add additional lots to the Qualification System. Applicants may apply for qualification in one or more lots. At the discretion of the Contracting Entity a full site visit and audit of the prospective Qualified applicants supply chain manufacturing facility(s) will be carried out to validate and support their pre-qualification submission. In the event of a site visit and audit being carried out to pre-qualify the Supplier must successfully pass this site inspection audit. It is envisaged that the scope of products and services of the initial Call for Competition to be drawn-down under the Qualification System will be, but not limited to; PE pipes, fittings and valves and will cover the following: 1. Standards: • Gas - as per I.S. EN 1555 or equivalent. 2. Indicative Diameter Range: • PE pipe, fittings and valves ranging in size from small diameter 20mm to large diameter 400 mm pipe and fittings. 3.
