Abstract	The SPIRAL2 facility at GANIL (Caen, France) has been operational since 2019. In 2027, the DESIR facility will begin receiving beams from the SPIRAL1 facility. At a later stage, DESIR will also receive radioactive ion beams from the S3-LEB facility, connected to the S3 separator of SPIRAL2. Construction of the DESIR building was completed in 2025. Many components of the beamline systems have already been manufactured and stored on-site at GANIL. Additionally, several experimental setups are currently under development and in the process of full qualification at partner laboratories, including HRS, GPIB, and PIPERADE at LP2IB, MLLTRAP and LINO at the ALTO-LEB facility (IJCLab, Orsay), and MORA at LPC-Caen. The DESIR facility requires long transfer and distribution beamlines to deliver beams to the experimental setups. Those beams can be passing throught many purification devices as high resolution separator and radio-frequency cooler buncher for high selection, emittance reduction and bunching. These lines are designed to transport mono-charged radioactive ion beams with energies up to 60 keV. Since 2012, various electrostatic systems have been developed and thoroughly reviewed as part of the beamline design process. This paper focuses on the already advanced installation of a beamline section and associated utilities and auxiliary systems located in the original GANIL building, which will enable the transfer of beams from the SPIRAL1 facility. It also provides a brief overview of the beam optics for the lines to be installed in the experimental hall, which will serve the experimental setups dedicated to nuclear physics research.
