         7 . The building management system of  claim 1 , the processing circuit further configured to:
 log maintenance information provided by a technician, the maintenance information describing an operating state of the building device; and   predict a change in a mode of the building based on the maintenance information.   
     
     
         8 . A method for maintaining building equipment, the method comprising:
 receiving asset data relating to operation of the building equipment, the building equipment operable to affect a variable state or condition of a building;   identifying a building device of the building equipment in a fault state based on the asset data;   generating a work order in response to identifying the building device in the fault state, the work order indicating a required maintenance action and a maintenance time window;   automatically populating a plurality of fields of the work order based on the fault state and   providing the work order to a user device.   
     
     
         9 . The method of  claim 8 , further comprising scheduling access permissions for a technician based on the work order. 
     
     
         10 . The method of  claim 8 , further comprising:
 retrieving troubleshooting instructions related to the building device; and   providing the troubleshooting instructions to the user device;   wherein the work order is generated responsive to an indication that a user is unable to fix the fault state based on the troubleshooting instructions.   
     
     
         11 . The method of  claim 8 , wherein the fault state is identified based on a determination that the building is not achieving a mode, the mode corresponding to at least one of:
 an operational mission for the building;   a job-to-be-done in the building; or   an event occurring in the building.   
     
     
         12 . The method of  claim 8 , further comprising:
 generating a maintenance alert indicating the fault state; and   providing the maintenance alert to the user device.   
     
     
         13 . The method of  claim 8 , wherein at least a portion of the work order is automatically populated based on the asset data. 
     
     
         14 . The method of  claim 8 , further comprising:
 logging maintenance information provided by a technician, the maintenance information describing an operating state of the building device; and   predicting a change in a mode of the building based on the maintenance information.   
     
     
         15 . A building management system comprising:
 building equipment operable to affect a variable state or condition of a building;   a control system comprising a processing circuit configured to:
 obtain a work order for the building equipment, the work order identifying a location of the building equipment and a time at which maintenance is to be performed on the building equipment; 
 schedule access permissions for a service technician based on the work order, the access permissions authorizing the service technician to access the location of the building equipment at the time at which the maintenance is to be performed. 
   
     
     
         16 . The building management system of  claim 15 , the processing circuit further configured to generate the work order in response identifying the building equipment is in a fault state.
