The provisional start date for the execution of works is November 2026. The provisional/estimated duration of the execution is six months. The contractual period is that proposed by the successful bidder and accepted by the client. The execution period begins from the date indicated in the service order issued by the client, which mandates the start of services. The market takes effect from the date specified on the service order for the commencement of the preparation period and concludes after the definitive acceptance of the services. Tenderers are required to submit a schedule with their offer, which may propose a more favorable timeline. The contract includes a firm tranche. The warranty period aligns with article 44.1 of the CCAG-Travaux.

The core scope of work for this tender primarily involves the installation of a photovoltaic system, along with all associated preparatory, structural, electrical, and finishing works at the SDIS 10 site in Sainte-Savine.

A high-level summary of the Statement of Work and core deliverables includes:

• Preparatory Works: This encompasses administrative procedures with concessionaires, an initial and final site assessment, provision of handling equipment, temporary site securing, development of a site installation plan, erection of a site sign, ensuring water and electricity supply to the site, setting up site premises, and defining site boundaries.
• Civil Engineering (VRD) Works: This involves identifying and detecting existing networks, the removal and transportation of streetlights, creating trenches and installing conduits, and establishing manholes.
• Structural Works (Gros Œuvre): This covers the laying of foundations, conducting a geotechnical study, and marking out designated spaces.
• Electrical Works: This includes adapting the existing main low-voltage switchboard (TGBT), installing luminaires, and pre-equipping terminals for electric vehicle charging infrastructure (IRVE).
• Photovoltaic Installations: This is a central component, comprising a structure study, installation of the support structure, supply and installation of canopies, implementation of the integration system (including its installation), supply and installation of arches at the base of poles, and fitting gutters. It also specifically includes the supply and installation of photovoltaic modules and a productivity study.
• DC (Direct Current) System: This part covers the routing of DC cables in capoted conduits (including grounding and labeling), installation of IP54 type MC4 connectors, DC cabling (monoconductor, C2, UV resistant, with cable fixation), connection boxes, DC electrical cabinets (with opaque door enclosures), DC overcurrent protection (disjoncteur, fusible), and DC switch/disconnectors.
• Inverter System: This involves the installation system for the inverter.
• AC (Alternating Current) System: This includes routing of AC cables (DC capoted, including grounding and labeling), AC cabling, AC electrical cabinets, AC switch/disconnectors, and 500mA residual current circuit breakers.
• Grid Connection: The connection to the site's existing electrical network.
• Safety Features: This covers fire safety, emergency stop mechanisms, and various signage elements such as pictograms, site entrance labeling, cable tray labeling, and electrical cabinet labeling.
• Grounding and Protection: Implementation of grounding and installation of surge arresters.
• Installation Monitoring: This involves a monitoring device, a pre-paid 4G key, a GSM module, an irradiation probe, and a temperature probe.
• Display System: This includes an LED TV screen, mechanical protection, a micro-computer, establishing links between the monitoring device and the display, and CFO (strong current) power supplies with 3PC (including electrical protection and TD connection) and CFA (weak current) connection.
• Finishing Works: This covers drilling, embedding, and filling activities.
• Execution and Reception Documentation: The provision of execution documents, commissioning activities, controls, tests, and adjustments. This also includes the formal reception of the works, submission of as-built documents (DOE), preliminary reception operations, and ensuring perfect completion of the project.
