What must happen for a truss member to be altered?

For a truss member to be altered, it is essential that the changes are vetted and approved by a registered design professional. This requirement ensures that any modifications maintain the structural integrity and safety of the overall truss system. A registered design professional, such as an engineer or architect, has the expertise necessary to evaluate how alterations may impact load distribution, stability, and compliance with building codes.

Altering a truss without proper approval could lead to potential structural failures, safety hazards, and non-compliance with regulations. This oversight is critical in the field of construction and building design, as it protects not only the integrity of the structure but also the safety of the occupants.
