SUMMARY OF FRAMING RED FLAGS
Beams: Protect the bottom flanges from cutting and other damage, and place sawn beams to take account of flaws (loose knots, splits, etc).
Trusses: Beware of pre-mature blocking of bottom chords. Be careful against damaging joints and cutting individual members. Be careful to avoid asymmetrical loading when installing roofing. Avoid using truss tension members as beams; if necessary to place heavy loads on the bottom of a truss, place the load point at or near a truss joint.
Plywood: For roofs and floors, be sure the face grain is normal to the support frame.
Re-roofing: Beware of roofing over an existing roof. Check dead loads.
Joints: Be careful not to over-nail.
Temporary Columns: Watch out for excessive un-supported length.
Double cross-braces: Be sure they are also connected together at the crossing point.
Manufactured members: Follow manufacturers’ recommendations for handling and temporary bracing.
