These tasks can be started now:
The door will be fitted with the same type of lock as used for G2 and G8. The lock is currently on order and all other components are in stock.
The floor has damage that will need to be filled. Then it can be painted or covered with vinyl (this is a more practical task than for G1 as the space is small and already empty).
ESD flooring has been proposed but is likely to be expensive. We have a roll of ESD flooring but it is soft (anti-fatigue, designed for standing workstations) and will be easily torn by chairs.
The sink cabinet can support its own (empty) weight if the legs are raised.
Cables will be run from the server rack in G11 (2-4 would be appropriate). A UniFi access point will be installed (this is in stock).
Proposed: 60-80cm benches against the long walls of the room. No bench on the short ends (because corners are too restrictive). Worktops will be installed at ~75cm height for seated use.
Use the short end (away from the door) for component drawers and pick bins. Shelving over the benches (some mix of general storage and ready-to-use equipment).
