The most important thing to take note while preparing form work is that; 

1. The ply wood is secure and timber is enough to support concrete weight and vibration while pouring, so the last pic shows the bracing given to support the concrete. the pics were taken few hours before completing the whole form-work.

2. Making sure the first step is level, using a sprite level, so that it ensures the fact that next steps will be leveled. 

3. Take accurate measurements from the last end of the step one to the grid line, and top end of the step to the grid line, in this sample it measure 820mm at bottom and top against the grid line.

4. for easy construction of form work, use 2inch x 1.5inch straight timbers, and nail or screw them together.
