COMMERCIAL BUILDING - FRAMING

Special Note: All approved building permit drawings, manufacturers shop drawings and details, necessary certifications must be in place prior to requesting this floor and/or ceiling framing inspection.

• Compare joists species, grade, size, clear span and spacing of the joists with design specifications, approved drawings, codes, and manufacturers details.
• Compare headers and girders species, grade, size, clear span and spacing of the joists with design specifications, approved drawings, codes, and manufacturers details.
• Determine if the length of the bearing point is at least 1½ inches if the supporting element is wood or metal, or at least 5 inches if masonry.
• Determine if the joists are supported by an approved and properly installed joist header or ledger strips at least 2 inches by 2 inches, where joists are framed into the side of a wood beam or girder.
• Verify that there are no notches in the middle 1/3 of any joist span.
• Verify that notches on the ends of the joist do not exceed ¼ the depth of the joist.
• Verify that notches between the ends and middle 1/3 of the span do not exceed 1/6 the depth of the joist.
• If the top notches in the ceiling joists exceed 1/6 of the joist depth, then verify that they are located no further than the joist depth from the face of the support and that they do not exceed 1/3 of the joist depth.
• Verify that notches are not longer than 1/3 of the joist depth.
• Verify that the tension side of the member is four inches or greater in nominal thickness and is not notched, except at the ends of the member.
• Check that there are no bored holes within two inches of the top or bottom of the joist.
• Confirm that the diameters of bored holes do not exceed 1/3 of the depth of the joist.
• Check that there are no holes within two inches of another hole or notch. Determine if the joists are toe nailed to the sills or girders with at least 3-8d nails.
• If posts are used to support beams and girders, then determine if positive connections are installed.
• Determine if the joists parallel to the bearing walls above are doubled OR an equivalent beam is used as a minimum.
• Determine if the header span is greater than four feet. If so, then the header is to be at least doubled.
• Determine if approved joist hangers are used to connect the header and trimmer joists for header joist spans greater than six feet.
• Determine if the ends of the joists NOT over an intermediate support, are laterally supported by full-depth, 2-inch thick solid blocking, a header, band or rim joist, or to adjoining stud.
• Ensure that 6' - 8' minimum headroom exists in all stairways.
• Verify that floor penetrations are properly fire safed with approved materials.
• Verify that spray on fire protection for structural steel members is applied completely.
• Verify that exterior wall veneer balloon framing is properly fire stopped.
• Verify that interior shaft walls are configured per the approved plan.
• Verify that Plumbing, Electrical and Fire Protection rough-in inspections have been approved.
