Up to six technical meetings per year may be held at the Commission premises in Luxembourg (no travel reimbursement). Deliveries are DDP to Commission addresses in Luxembourg; there are separate delivery addresses depending on package size and weight. Packaging and delivery costs are borne by the contractor. Typical completion times: 20 working days for orders not exceeding 40 hours and not requiring special tooling; time extensions apply when specific materials or engineering drawings are required.

Procurement model and contracting arrangements

Single framework contract awarded to a single contractor. The framework establishes the conditions for awarding specific contracts (or issuing order forms) for individual tasks. The contracting authority is not obliged to place any minimum number of specific contracts and may cancel the procurement procedure up to signature without compensation. Requests for offers from the contractor will specify turnaround times (quotations expected within 21 calendar days unless changed in exceptional cases). The contracting authority may use an electronic exchange system (EU Funding & Tenders Portal) and may make its use mandatory for the contractor at no additional cost.

Evaluation and award

Award criterion:lowest price (100%). For price comparison the contracting authority requires bidders to prepare technical quotations for six representative example projects (Annex 7). The financial evaluation uses the sum of the six example prices submitted in the financial template (Annex 6). Tenders will be ranked in ascending order of total evaluated price and awarded to the lowest compliant tenderer.

Eligibility, exclusion and selection

Participation is open to natural and legal persons as permitted by the EU Treaties and applicable international agreements (e.g. WTO GPA). Tenderers must not be subject to EU restrictive measures and must comply with exclusion criteria in Article 138 of the Financial Regulation. Proof of non-exclusion is provided by the Declaration on Honour (Annex 2). Selection criteria include demonstrable economic/financial capacity and technical/professional capacity as specified below.

1. 1Economic and financial criterion (F1): average annual turnover over the last two financial years above €90 000 (consolidated assessment across involved entities permitted). Evidence (e.g. profit & loss accounts) may be requested by EU Validation Services.
2. 2Technical and professional criterion (T1): experience machining relevant materials and at least one similar project in the last three years. The tenderer must demonstrate the capacity to machine at least three of the listed materials including at least one material with toxic properties (lead, cadmium, tungsten).

Contractual, legal and security obligations

Contracts will be executed under the EU Framework Contract General Conditions (FWC conditions of December 2024). The contractor must comply with Commission security requirements (Appendix 2 Security Requirements for Commission’s Contractors) including cybersecurity measures (Regulation (EU, Euratom) 2023/2841) and possible security clearances for personnel. The contractor must implement appropriate information security and incident reporting (notify contracting authority within 48 hours of security incidents), and will bear all costs related to security requirements. No access to EU classified information is anticipated under the FWC.

Financial model, pricing and invoicing

Bidders must use the financial form (Annex 6) and submit hourly rates per technician for four task types, plus all-inclusive prices for the six example projects. The total price used for evaluation is the sum of the six example project prices. Prices must be quoted in euro, excluding VAT. The Commission is generally VAT-exempt; group members in joint tenders receive VAT annexes where local VAT rules apply (Annex IV). Payment: the contracting authority normally pays invoices within 30 days after approval, subject to the suspension rules in the FWC. No pre-financing or interim payments are indicated in the tender documents.
