Penetrations: The Choreography of Construction and Mechanical Techniques

Penetrations characterize the intentional openings or pathways created inside structural components to accommodate mechanical methods. They are often something from small holes for electrical conduits to bigger openings for HVAC ducts or plumbing. As buildings intention to be extra built-in and compact, the necessity arises for mechanical methods to traverse by structural elements. Whether or not it’s to make sure an optimized structure, keep aesthetics, or just present important utilities throughout the constructing, these penetrations develop into a vital a part of the design course of.

Penetrations: The Choreography of Structure and Mechanical Systems
