The permit is for Flight of Passage and Navi facility building. While we can't see it those two rides are in the "same" building and share facilities like utilities etc. It is why if there is a big issue with one (like smoke), they both have to evacuate.
The permit states that it is for the "ride facility" - labor, material and electrical. No end date so that means less than one year. If it were anything new or of consequence it likely have an end date. Probably just some upgrades or general maintenance.
The company doing the work does "Heating, Ventilating & Air Conditioning Service".
