(LAL Opening at the right location with 100% sure that every birds will fly above or into it)
One of the most tedious and dusty operation was to open the Lubang Antara Lantai (LAL) on the top floor.
At first glance it looks very simple and easy.
Once you get started you will know that the job was messy, dusty and full of heat problems.
The floor thickness was a bit on high thickness side. I was expecting something like 4 to 5 inches but it was much higher 8 inches.The top layer about 3 inches were pretty easy to break opened. However once you passed this phase you have a solid cement with three layers of steel grating.
You need to cut, hammer and drill.
After one and half solid days the opening was completed and now lining the perimeter with proper finishing.
I don't enjoy working around the BH during this time of the operation.
I was very lucky to have a dedicated group of workers.
Once they started the work they will finished till the end.
At last we have a sizable LAL inside the BH to push them to populate the lower floor.
The location chosen was precised and it size was about 3 feet by 6 feet.
I guaranteed the owner that all birds than entered his nesting rooms will fly above or into the LAL.
This is the only way to get their attention to fly to the lower floors.
Remember by advice: Choose the right location where 100% of all those birds that entered into your BH will fly above or into it.

(Select the right location and start digging)
(There were two layers of concrete and three layers of wire mesh)
(Once completed the sides were smoothed with cement filling. It looks nice.)
