A plumber asks to notch a metal-plate-connected wood truss web to clear a vent line. The web is not shown as altered on the truss drawings. What is the proper response?
Correct Answer
B) Do not cut; get an engineered repair detail first
Do not make the proposed cut. Send the truss identification, drawings and conflict details through the manufacturer/designer for a specific approved engineering disposition before alteration. A rule for notching ordinary lumber cannot authorize cutting an engineered truss web. Source: https://kcenter.sbcacomponents.com/resource/sbca-knowledge-center-design-of-truss-repairs-dg-no-2501
