Modernisation de l’infrastructure réseau de l’Administration Communale de Hesperange

The contract timeline is structured as follows:

• Execution Phase Start: The launch meeting, which occurs at J+110 minimum, following the expiration of the standstill period and the placement of the order.
• Total Execution Duration: A maximum of 16 weeks, calculated from the launch meeting.

The key milestones and phases during the execution are:

• Audit and diagnosis: Weeks 1 to 2, starting from the launch meeting.
• Target architecture design: Weeks 3 to 5, contingent on the validation of the audit report.
• Equipment procurement: Weeks 6 to 13, following the validation of the design document, with staggered deliveries per site. This phase runs in parallel with deployment and does not extend the total duration.
• Deployment and integration: Weeks 6 to 13, with site preparation and cabling commencing from Week 6, and site-by-site migration as equipment is delivered.
• Tests and acceptance: Weeks 14 to 15, upon the completion of deployment across all three sites.
• Documentation and training: Week 16, after provisional acceptance.

The critical path for the execution phase is 3.1 → 3.2 → 3.4 → 3.5 → 3.6, totaling 16 weeks.

• Provisional Acceptance (Recette provisoire): This occurs after the completion of tests and validation, marking the end of the 16-week execution phase.
• Guarantee and Maintenance Period: This period lasts for 5 years, commencing from the date of provisional acceptance.
• Final Acceptance (Recette définitive): This takes place 12 months after the provisional acceptance, signaling the end of the legal warranty period.

The core scope of work for this tender, aimed at the "Modernisation réseau 2026" for the Administration Communale de Hesperange, encompasses three main areas: equipment supply, service deliverables, and maintenance.

The equipment supply includes Access Switches (REQ-1-XX), Core/Datacenter Switches (REQ-2-XX), a NAC Solution (physical appliance + licenses) (REQ-3-XX), optical modules, transceivers, connection cabling, and software licenses for management, supervision, and security. It also requires a network management and supervision platform with a single management point, advanced diagnostics, and NAC integration for Access switches. All supplied material must be new, of the latest generation, and come with a minimum 5-year manufacturer warranty. Compatibility with existing HPE infrastructure (2500, 5400, 6000 series) or equivalent equipment is mandatory, along with verifiable origin, CE conformity, and safety certifications.

The service deliverables involve:

• An audit and diagnostic of the existing infrastructure (Phase 3.1 - 2 weeks), which includes an exhaustive inventory of network equipment, detailed mapping of the current network topology, analysis of existing configurations (routing, security, QoS, VLANs, ACLs), and network flux analysis to identify congestion points. Deliverables for this phase are a technical audit report, network diagrams, and equipment inventory.
• Conception of the target architecture (Phase 3.2 - 3 weeks), focusing on the elaboration of a detailed technical solution, design of a redundant ring architecture (physical and logical), precise equipment sizing, optimized IP addressing plan and VLAN segmentation, and a security architecture (802.1X, NAC, MACsec). Deliverables include a detailed design document and architecture diagrams.
• Deployment and integration on three sites (Phase 3.4 - 8 weeks).
• Tests, acceptance, and production launch (Phase 3.5 - 2 weeks).
• Provision of technical documentation and training for the ACH teams (Phase 3.6).

Overall, these services cover the supply, installation, configuration, commissioning of new network equipment, implementation of a redundant inter-site architecture, migration services, maintenance, supervision, and operational support. The maximum contractual deadline for these phases is 16 weeks from the launch meeting.

Maintenance services are provided as an annual fee for one year and include:

• Manufacturer's hardware warranty for a minimum of 5 years.
• Preventive and corrective maintenance in accordance with SLA §9 CDC.
• An emergency stock, specifically 2 Access switches, 2 Core switches, and 1 NAC appliance, as per §9.2bis CDC.
• Firmware updates and security patches (REQ-0-01), with application within 14 days for CVSS scores ≥ 7.0 (CDC §9.4).
• 24/7 supervision and MCO, including remote surveillance, proactive real-time monitoring, intervention triggering upon alerts, and incident reports after each intervention (CDC §9.6).
• Technological watch and quarterly reports, involving analysis of technological evolutions, recommendations for optimization, and a written report delivered to ACH every three months (CDC §9.5 - 20 reports over 5 years).
