Regulus:
In the German Army there was an organization that was responsible for the construction of aircraft sheds and hangars, it was Hallenbau-Kompanie Nr.1 and Nr 2. established 5 April 1916
In the Bavarian Army was the Bayern Flieger-Bau Batl. composed of Zelle-Bau Trupp 26,27, 57, 58, 59 und 60. established 17 April 1917.
Sheds built by the Hallenbau had flat plain boarded fronts, The sheds built by the Zelle-Bau Trupp had an open truss work across the top front of the shed.
These units set up these sheds and when the field was closed they took down the sheds and moved them to the new field.
I would imagine that there was a simular organization in the Navy. The airship hangars were built by civilian contractors. I think the Zeppelin Werke had a Hangar Construction Company too.
The Tent hangars were set up by personnel within the unit. Generally each Flying unit would have two personnel for the maintenance of the tents. The aircraft ground crew pitched in in setting-up the tent hangars. The hangars and work sheds were lighted with electric lights. Power was provided by the engine driven generator truck(lorry).
