• Phase SIA 31 (Avant-projet): Estimated start on January 1, 2027, and estimated end on July 2, 2027.
• Phase SIA 32 (Projet d’ouvrage): Estimated start on August 2, 2027, and estimated end on February 4, 2028.
• Phase SIA 33 (DAP): Estimated start on March 6, 2028, and estimated end on November 30, 2028.
• Phase SIA 41 (Dossier AO): Estimated start on August 1, 2028, and estimated end on February 27, 2029.
• Phases SIA 51 to 53 (Projet d’exécution / Réalisation / mes): Estimated start in March 2029 and estimated end in December 2029.

The completion of each phase between SIA 31 and SIA 41 is to be marked by a formal presentation of studies by the contractors. The validation of these studies and their deliverables by the Client is required to launch the subsequent partial phase. The parties will agree on the schedule for the execution of phases SIA 51, 52, and 53 after adjudication.

The contract start date, end date, and total duration are not explicitly stated with fixed dates; placeholders (JJ.MM.AAAA) are provided for "Date de début de mandat" and "Date de fin de mandat."

The core scope of work and statement of work for this tender involve the comprehensive management and execution of a project using Building Information Modeling (BIM) methodology.

Key aspects include:

• Project Organization and BIM Deployment: Defining project management with BIM, deploying the BIM method, and ensuring its continuous follow-up throughout all project phases. This includes the production of a complete BIM project documentation, such as the BIM Execution Plan (BEP), BIM coordination plan, and BIM control plan for mandates. Quality control automation and adherence to applicable standards and norms are also integral.
• Document Elaboration and Updates: Developing and regularly updating project documents, both those linked and not linked to digital models, in accordance with project phases and directives. This covers schematic diagrams (electrical, ventilation, hydraulic, sanitary, sprinkler), general operating synoptics, power balances, and calculation notes for various purposes including building permits and technical elements.
• Planning and Design Documentation: Producing various plans and detailed drawings, such as rental surface plans, constructive details, plans of Ainside/Landside limits, commissioning plans, zoning plans incorporating flows and accessibility routes (PMR), detailed plans based on global design charters, fire safety plans, phasing plans, 2D drawings for exterior landscaping, landscape plans, plans of surrounding areas, and exterior network plans. It also includes 2D drawings for hydraulics and ventilation systems.
• Technical Studies and Analysis: Conducting specific studies like ORNI (electrical), establishing qualitative descriptions for tender calls, developing schematics for fire protection control principles, performing functional descriptions and analyses that integrate technical specifications, and executing multi-criteria analyses of variants. Capacity studies are also mentioned.
• Cost Analysis: Estimating project costs per cubic meter, utilizing surface and volume data extracted from digital models. This involves producing architectural, space, and CVSER BIM models, along with corresponding cost estimation documentation.
• Sustainability Integration: Implementing a low-carbon concept and calculating the carbon footprint of the project by integrating material carbon data into the digital models.
• Existing Infrastructure Integration: Performing surveys and identification of existing elements and installations to integrate them into models and 2D plans for coordination. The project's perimeter encompasses a direct physical area and an extended area that includes all relevant networks, technical centers, and adjacent zones with functional technical links (e.g., fire detection, sprinkler, or evacuation areas).
• Site Management and Phasing: Managing cohabitation between tenants and ongoing works, maintaining active spaces through a defined relocation scenario, and handling multiple-stage moves and relocations. The scope also includes dismantling/deconstruction, complete floor covering changes, and adaptation of technical raised floors.
• Coordination and Authorization: Elaboration of coordination drawings indicating accessibility for technical elements and reserve locations, as well as plans for authorization and tender processes. Integration of fire concepts into plans.
