Designation of a design office for a feasibility study on the renovation of the current renewable energy production system of the ULiège central heating plant (site B10), as well as project management assistance for the execution of the project, with a view to energy transition

This service contract concerns the designation of a design office specialized in special techniques, and particularly in large-scale heat production, for the renovation of the current renewable energy production system of the ULiège central heating plant on the Sart Tilman campus (site B10). This project is part of ULiège's Energy Transition Roadmap. The requirements for the installation of decarbonized production means will be studied within the framework of energy optimization and reduction of the carbon footprint of the Sart Tilman Central Heating Plant (CCST) while respecting the structural, technical, planning, and organizational constraints of the site. The service mission is structured as follows: - FIRM TRANCHE - Feasibility studies * PHASE 1 - carrying out a complete technical study of the renovation solutions (including the study of a possible complete or partial replacement – see also the guidance note) of the current renewable energy production system of the Sart-Tilman Central Heating Plant (hereinafter referred to as CCST) and comparative analysis of scenarios based on technical, economic, and environmental criteria. This study must enable ULiège to validate the scenario to be chosen for the renovation of the CCST. * PHASE 2 - based on the scenario chosen by ULiège, drafting the technical performance specifications and the layouts and schematic diagrams allowing ULiège to launch a works contract, (a priori in Design and Built), for the implementation of the chosen scenario. - CONDITIONAL TRANCHE - project management assistance mission for the execution of the project, according to the scenario chosen by ULiège at the end of the feasibility study which is the subject of the firm tranche. * PHASE 3 – assistance to the project owner for the designation of the contractor for the works contract (DESIGN and BUILT), including negotiation sessions with the bidders, * PHASE 4 – assistance to the project owner for the supervision of the DESIGN&BUILD contract, including the detailed design phases and production of "good for execution" documents (DESIGN), supervision of execution (BUILD), and provisional acceptance * PHASE 5 – assistance to the project owner during the warranty period, including final acceptance The conditional tranche will be activated by ULiège according to needs, established at the end of the firm tranche, to engage the design office's expertise for a complementary project management assistance mission and within a maximum period of 2 years from the end of the firm tranche. The description of the mission expected for each tranche and each phase is detailed further in this document and its annexes (e.g. technical clauses for the execution of the contract).

The project and its technical, economic, phasing, and environmental expectations are described in more detail in the guidance note, which is an integral part of the market documents, explaining the objectives, constraints, and technical, economic, and quality environmental criteria that the University requires within the framework of this contract.
