My workers have also half way into finishing the brickwork of the Utility Room on the Ground Floor. At each corner of the Utility Room is a boxed-up duct (2' 0" x 2' 0") which runs from the Ground Floor to the underside of the 1st. Floor. It is a multi-purpose duct which serves the following purposes:-
1. Acts as a refuse chute. Birdshit are dumped into this duct and dropped to the ground
2. Acts as a service duct. Water pipes and electrical conduits from the Ground Floor run inside the duct to the 1st. Floor and above.
3. Acts as a ventilation duct. Air from the ground rises and flow into the duct and into the air well above the 1st. Floor regulating the temperature and humidity in the interior of the BH. Air movement is restricted to the air well area only and does not affect the nesting places.
4. May act as a feeding tube. This is just an idea. I may breed insects as food for the swiftlets on the ground and channel them through this duct into the interior of the BH.

You mean the duct serves 4-in-1 purpose or each duct serves one purpose only ?
The bird droppings are washed down the chute or packed into bag and throw down the chute ?
KL,
All the service ducts are multi-purpose, that is 4-in-1, as you call it and can be used for any of the mentioned purposes. So choose the nearest duct. The bird droppings will be thrown down the duct and collected on the ground. I will not practise washing down.
