Procedure

1. Mark the positions where we need to place the supports.
   
2. Place the HD towers in the lab. Basically, HD Towers are made by erecting props on base plates and U head at the top of props.
   
3. Attaching Horizontal and Diagonal Bracings to support HD Tower. This whole makes a basic frame.
   
4. Placing Aluminium and Timber Beam on top of the basic frame. Here, aluminum beams are placed on U heads. Timber beams are placed perpendicularly on aluminum beams.
   
5. Sheathing and Nailing: Plywood sheets are nailed on these H beams.
   
6. Placing Inner and Outer beam with BFS. Using BFS, Inner and Outer beams are made to stand.
