A5.

Orientation Verify visually, that the member orientation is as shown on the design drawing.

i 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.)

a.

Location Verify that the location of all field performed alterations are within i 1/8" of the location specified on the design drawing, relative to the member, b.

Size Verify that the dimension (s) of the field performed alteration is less than or equal to the dimensions specified on the design drawings.

c.

Limit of Alterations 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. However, should a support attachment be encountered during the reinspection, Attachment 6.15 l

shall be completed.

B3.

Orientation Verify visually, that the connection is orientated, j

relative to the member, as specified on the design drawing.

Field Welds l

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 I

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.

i 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.

In floor and roof areas where topping has been placed, the thickness of the topping shall be taken into account in determining the projected length. 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.

    • NOTE: When the letter designation stamped on Hilti bolt is not identified by Attachment 6.6, the following Hilti bolt attributes regarding length of Hiltis can conservatively be inspected by using Attachment 6.16.
