Access panel is required to replacement of fusible link of fire damper. Normally used 450mmx450mm or you can increase or decrease as per site conditions and duct sizes.
This area of TDF flange, joints and also scrap normally do not calculate because it is difficult to calculate therefore mostly we add safety factors % for this purpose to increase the duct area.

The designer provides airflow(cfm) and sizes of air devices (diffusers, grills, etc.) in construction drawings. we have to order the air devices according to the sizes given in the drawing. When we air balance after installation, we adjust (partially open or close) the damper according to the given airflow in the drawings.
