The M120 Heavy Civils Enabling Works Framework Agreement (the M120 Framework) will provide civil engineering works for the MetroLink programme. The scope of works for the M120 Framework will comprise a combination of the following: Site set up and hoarding installation; Logistics and welfare management; Utilities diversions and works; Site clearance and removal of materials; Surveys and/or ground investigations; Bulk earth and rock excavation works; Construction and outfitting works; Building construction and fit-out; Construction of single or multi-span viaducts, overbridges, under bridges and walkways over or under live carriageways and waterways, retaining walls and guide walls, diaphragm walls, secant piling and contiguous piling, rock bolts, anchors, capping beams, shotcrete works, mesh works, sealing of fissures etc., underground and above ground reinforced concrete structures and associated temporary works/propping/other reinforcement works; Monitoring of settlement and ground movement and associated remedial works; De-watering and water treatment/disposal management; Site waste management; Mechanical , electrical and plumbing works as required, perform the roles of PSDP and PSCS; Structural, civil, and engineering design; Any other related works. The procurement of the M120 Framework (the Competition) will be conducted under the European Union (Award of Contracts by Utility Undertakings) Regulations 2016 (as amended) (SI 286/2016), and will be managed by TII, acting as the contracting authority, who will be the sole point of contact for applicants. The M120 Framework will be a multi­-party Framework Agreement (per Regulation 50 of the Utilities Regulations) consisting of two (2) value based lots. The competition will be structured as a two­-stage process with Stage 1 the Selection Stage and Stage 2 the Tender Stage. A maximum of three (3) tenderers will be appointed to each lot. Applicants may apply for one (1) lot only. A tenderer appointed to either lot under the M120 Framework is not precluded from participating in other MetroLink projects or contract packages. The lots are as follows: Lot 1 - Heavy Civils Enabling Works for Call-off Contracts with an estimated value of €50 million or more (excluding VAT) and those determined by the Contracting Authority to be complex call-off contracts of any value which may require specific technical or specialist resources. Lot 1 will consist of call-off contracts for large elements of civils works, which may include station boxes, tunnel portals, single or multi span viaducts, and other contract packages. Lot 2 - Heavy Civils Enabling Works for Call-off contracts with an estimated value less than €50 million (excluding VAT) except those to be included in Lot 1. Lot 2 will consist of call-off contracts for elements of civils works, which may include retaining walls, other foundation/support works. Conduct of the Competition Stage 1: The Selection Stage will commence with the publication of a Pre-Qualification Questionnaire (PQQ) by TII. This will assess applicants based on defined selection criteria for each lot, such as their financial and economic standing, technical capability, and relevant experience. Provided that there is a sufficient number of applicants for each lot, five (5) applicants for each of the two (2) lots will be shortlisted. If less than five (5) applicants meet the minimum requirements for a lot, TII reserves the right to proceed with those applicants to the second stage of the procurement for that lot. The PQQ process to establish both lots will run concurrently. Stage 2: The Tender Stage for the award of the framework and first call-off contracts will commence with TII issuing the Invitation to Negotiate (ITN) to each tenderer for that lot. Following the submission and evaluation of ITN tenders, TII reserves the right to engage in further negotiations with tenderers. Following the negotiation phase, TII may request the submission of Best and Final Offers (BAFOs). The three (3) highest ranked tenderers under each lot will be appointed to the M120 Framework and will be eligible to compete for future call­-off contracts. The 4th and 5th ranked tenderers under each lot will be reserve tenderers. If during the term of the M120 Framework a framework contractor no longer meets the financial and economic standing requirements in the PQQ or does not submit a tender in response to a call-off tender for three or more call-off contracts in a row then TII reserves the right to terminate the framework agreement with that contractor and appoint one of the reserve tenderers to the M120 Framework. Furthermore, the highest ranked tenderer under each lot will be awarded the first call-off contracts under each lot: Lot 1 award of the contract for the Dublin Airport station box (see 5.1 Lot: LOT0001); Lot 2 award of the contract for the Glasnevin station retaining wall (see 5.1 LOT 0002). Future call off contracts will be awarded by way of mini-competition following the issue of the call-off tender document to the framework members. Detailed information regarding the award criteria for the future / subsequent call-off contracts after the first call-off contracts will be communicated to tenderers appointed to each lot of the M120 Framework as they arise based on TII’s requirements. The M120 Framework may also be used by Iarnród Eireann - Irish Rail to procure call-off contracts for heavy civil engineering works at or adjacent to Glasnevin station (including, without limitation, retaining wall construction, ground stabilisation, utility diversions, interface works with the MetroLink alignment, and preparatory or enabling works necessary to facilitate the integration of MetroLink with the existing Irish Rail network at that location), provided that the works in question fall within one or more of the categories of work set out in the scope of works for the M120 Framework. Refer to the PQQ documents for further information.
