Final answer:
In construction, a beam pocket must provide adequate clearance around a beam for ventilation and movement; this is necessary to maintain the integrity and safety of the structure.
Step-by-step explanation:
A beam pocket is a recessed space designed to hold the end of an intersecting beam in a concrete wall, a masonry wall, or a column. Beam pockets in exterior structures are often subject to water leakage. A beam pocket or wall notch is designed to allow the top of a girder to be flush with the top of the sill plate in construction.
To ensure proper function and safety, the beam pocket should be sized to provide adequate, sufficient, ample, or satisfactory clearance around the sides and ends of the beam. This clearance is essential for ventilation and to allow for any potential expansion, contraction, or movement of the beam.
