Description:
Geotechnical studies are required for the rehabilitation of an existing building into a hydrothermal plant utilizing energy from the Garonne, focusing on design and execution necessary for the installation of high-technology heat pumps.

This consultation is part of the Public Service Delegation (DSP) related to the urban heating and cooling network "Plaine Campus," awarded by Toulouse Métropole to the company Toulouse Énergie Durable (TED). To address the challenges of energy transition and supply security, amendment no. 7 to the DSP contract provides for a significant extension of the network and densification of production means through renewable energies. The operation involves the creation of an innovative heat production tool using energy from the Garonne. This project aims to increase the net renewable energy (EnRR) rate of the network to over 85%. The project involves the rehabilitation and transformation of an existing emblematic building located on the Île du Ramier into a hydrothermal plant of 5.5 Mc. This site, subject to strong technical, heritage, and environmental constraints, must accommodate a cascade of high-technology heat pumps (PAC) utilizing thermal energy captured from the Garonne. The project requires exemplary treatment.
