Field Notching and Drilling of Laminated Veneer Lumber

Laminated veneer lumber (LVL) products are often specified where a certain span, strength and/or stiffness is required. As such, they are generally designed for and used in applications where they will be highly stressed under design loads. For this reason, field modifications such as notching, tapering or drilling that are not shown on the design or shop drawings should be avoided.

This publication is designed for: builders, contractors, architects, engineers, designers

This technical note provides prescriptive recommendations for field notching, tapering and drilling LVL beams. A cautious approach to field modifications is vital.

Key sections include:

• Notching

• Shear design equations for notched and tapered LVL beams

• Holes

  • Horizontal holes

  • Vertical holes

  • Holes for support of suspended equipment

• Protection of field-cut notches and holes
