  This paper outlines the centralised design and production of the
Ultra-High-Vacuum sidearm and Laser-Stabilisation systems for the AION
Ultra-Cold Strontium Laboratories. Commissioning data on the residual gas and
steady-state pressures in the sidearm chambers, on magnetic field quality, on
laser stabilisation, and on the loading rate for the 3D Magneto-Optical Trap
are presented. Streamlining the design and production of the sidearm and laser
stabilisation systems enabled the AION Collaboration to build and equip in
parallel five state-of-the-art Ultra-Cold Strontium Laboratories within 24
months by leveraging key expertise in the collaboration. This approach could
serve as a model for the development and construction of other cold atom
experiments, such as atomic clock experiments and neutral atom quantum
computing systems, by establishing dedicated design and production units at
national laboratories.
