The inspector must insure that all reinforcing steel has been fully secured in proper position in advance of concrete placement.

may furnish extra bars to which support hardware can be welded. No additional payment will be made for these bars. Do not permit reinforcing steel to be placed by pushing into fresh concrete. This practice is commonly known as "stabbing steel".
