Mission de diagnostic dans le cadre de la réhabilitation de 60 logements locatifs sociaux collectifs résidence « SOURAS BAS »

The contract is expected to start provisionally in October 2026. The official start date will be counted from its notification date. The services will conclude upon the validation of the mission by the Contracting Authority. The contract will not be renewed. Key milestones include a maximum 2-month deadline for the DIAG realization (from notification), which encompasses the launch meeting, visits, an intermediate meeting, and final restitution. Additionally, the Contracting Authority has 30 days to approve the DIAG from the date of document reception. The total duration is not explicitly stated as a fixed period, but rather defined by these conditions and deadlines.

The core scope of work for this tender is to conduct a comprehensive Technical Diagnostic of a social housing property, specifically the "SOURAS BAS" residence. This diagnostic is a prerequisite for defining a rehabilitation program and preparing for future consultations related to project management or construction works.

The Statement of Work (SOW) includes the following key aspects and deliverables:

• Overall Mission: To provide the contracting authority with all necessary technical, functional, regulatory, energy, economic, and patrimonial information to define a rehabilitation program.
• Diagnostic Content:
• Detailed analysis of significant building elements based on visual condition.
• Description of exterior elements such as walls, fences, roads, curbs, green spaces, and parking areas, including their nature and dimensions.
• Assessment of thermal, acoustic, and phonetic performance, including an energy audit (THCEX and 3CL deliverables) and proposing modification scenarios to meet or exceed current standards (e.g., BBC label), along with associated costs.
• Analysis of accessibility for both disability and aging, providing modification proposals to meet normative requirements for each aspect individually and synergistically, with associated costs.
• Evaluation of PLUMBING SANITARY, VENTILATION, ELECTRICITY, GAS, TERRACES BALCONIES LOGGIAS, and EXTERIOR FITTINGS.
• Key Deliverables:
• An executive summary for management.
• A comprehensive diagnostic report.
• Geolocated photographic survey or annotated plans as needed.
• A mapping of identified disorders.
• A prioritized table of interventions.
• Detailed cost estimates of works by trade, including a provisional breakdown (DPGF).
• An indicative intervention schedule.
• Multiple rehabilitation scenarios, each detailing objectives, work nature, advantages/disadvantages, technical, energy, and operational impacts, estimated costs, and provisional timelines.
• General conclusions on feasibility.
• A complete energy audit with regulatory deliverables and simulations, specifying conventional consumption, expected energy gains, greenhouse gas emissions, improvement scenarios, costs, and estimated return times.
• A consolidated report incorporating feedback from the restitution meeting.
• Deliverable Format: Documents must be submitted in PDF (signed), Word (for editable content), Excel (for tables and estimations), and DWG or other native formats (for plans), ensuring all files are freely exploitable without protection.
• Objectives for Future Work: The mission aims to identify work for:
• Objective 1: Minimum treatment of all safety-related items for goods and people, with cost estimates to achieve conformity.
• Objective 2: Including Objective 1, implementing solutions to achieve BBC RENOV thermal performance, targeting a significant improvement in thermal balance post-works.
• Exclusion: The successful bidder for this diagnostic market is explicitly prohibited from participating in any subsequent project management consultations for the rehabilitation of the "SOURAS BAS" residence.
