A5. Orientation Verify visually, that the member orientation is ao shown en the design drawing.

A6. Field Performed Alterations The removal of material, i.e. cutting, notching, or coping, af ter the initial vendor fabrication, shall be considered a field performed alteration. Additionally, any member site fabricated shall be inspected for the ,

following attributes.

(Site fabrication shall be  !

determined by the QA/QC Discipline Engineer and noted in the remarks section of the checklist under the member attribute heading.) 4

i Verify that the actual alterations are limited to those specified on the design drawings. Attachments to structural steel by other disciplines, i.e.. electrical cable tray supports, HVAC supports etc., shall not be considered an alteration and are outside the scope of this reinspection.

e. Cuts & Holes I

Verify that all field performed cuts & holes '

(excluding bolt toles) are without torn or i ragged edges, j B. Connections For each connection to other building elements and member I splices, perform the following inspections:

Bl. Location Verify that the location of the connection component work points, other than bolts / anchors and/or welds (see sections B4 through B7) relative to the member, is within 1/8" of the location soecified on the design drawings.

B2. Size Verify that the connection components, other than '

bolts / anchors and/or welds (see sections B4 through B7), are as specified on the design drawings. For O. structural shapes and plate use the nominal dimensions V and the standard mill tolerances listed in References 3.3 and 3.4. Components cut from stock shall have a tolerance of 2 1/8" for length and width and + 1/8", -0 for thickness.

B3. Orientation Verify visually, that the connection is orientated, relative to the member, as specified on the design drawing.

B4. Field Welds Prior to the start of inspection assure that welds are clean of any foreign material which would impede an adequate visual inspection. Coatings need not be removed unless an inspector feels that due to excessive and/or uneven coating application he is unable to provide an adequate inspection of the weld. Then he shall contact the level III inspector and with his concurrence only then may the coating be removed.

Where it is necessary to measure weld dimensions during the course of an inspection, such dimensions should be determined as accurately as is practically achievable using standard weld inspection tools.

Determine the Hilti anchor bolt embedment by measuring the projected length of the anchor bolt from the structural concrete

In these areas the thickness of the topping shall be added to measured length taken from the concrete surface. The inspector shall ensure that measurement for topping is provided on the inspection checklist for all roof and floor slabs.

    • Minimum spacing between holes covered by this column shall be measured center-to-center and based on size of hole being drilled. (e.g., Pilot hole spacing is based on pilot bit size.)

Hilti bolts may be installed as close as practical to unused Richmond Screw Anchcra which have been plugged (i.e., grouted, Richmond Screw-in plug or snap-in plug, etc.).

NOTE 1: Where embedded angles are used for framing water tight door or removable block wall openings, the minimum clearance from center line of Hilti anchor to the opening edge is 5 inches + 5 times the Hilti anchor diameter.
