The structural steel connections at the locations mentioned above were found to be in accordance with the reference
documents, except for item 1a inconclusive, item 1b in progress and item 1c failed. The General Contractor will call for
items 1b and 1c re-inspection after completion for final compliance verification. The welder qualification certificate was

considered as remaining in effect indefinitely unless:
(1) the welder is not engaged in a given process of welding for which the welder or welding operator is qualified
for a period exceeding six months, or
(2) there is some specific reason to question a welder’s or welding operator’s ability (see 6.25.1).

200 at the following locations indicated below:
a) Cleanness/depth check (6” min. embedment) for #6 vertical rebar dowels into existing CMU bond beam/CIP
concrete headers at gridlines F.4x3.5 and F.6x3.6 (men’s locker room and J.C.) at the existing service building, as
