Moving a threshold requires a new glide slope at the very least, and then the glide slope ILS must be checked for terrain and obstruction clearance, the idea being that if you’re cleared for the ILS 9R you have a cone of protection around the ILS beams where your plane can deviate slightly and not run into anything.
All I know is this process takes time to complete and is likely why they aren’t able to land that runway yet.

Obviously any new or changed ILS infrastructure would need to be calibrated and tested after the runway is complete, but what about RNAV and GPS based approaches? Since they know where the new threshold will be, presumably they (the FAA) could get those going sooner since all they really need are the GPS coordinates of the new threshold and could test while other work on the ILS infrastructure continues? I assume 09R/27L will be used more for departures than landings in general, so will it get a full complement of ILS and RNAV approaches?

They usually sync this up with the project, fly it, then publish the procedure shortly thereafter. I’ve seen them use temporary threshold bars to do the flight check. Usually set up the Localizer approach first, then bring up the Glideslope the day the procedure goes live. Usually takes 2-3 years to coordinate things so the flight check is completed within a couple of days of the IFP going live.
