reinforcing steel, also called rebar, is an important material for the construction industry used for the reinforcement of structures and other works that require this element, in accordance with the designs and details shown in the plans and specifications. Due to its importance in buildings, its quality must be verified and studied. Reinforcing steel products must comply with certain standards that require verification of their strength, ductility, dimensions, and physical or chemical limits of the raw material used in their manufacture.

The rebar is, partially or entirely, embedded in the concrete.

Reinforcing bars shall be cold bent in accordance with the details and dimensions shown on the drawings. Bars that are partially embedded in the concrete may not be bent on site, except when indicated on the plans or authorized by the site inspector. All reinforcing steel shall be placed in the exact position shown on the plans and shall be securely secured, in a manner approved by the Engineer, to prevent displacement during placement of concrete. Wire and, in special cases, welding will be used to tie the rods. The distance from the steel to the forms will be maintained by means of prefabricated mortar blocks, tensioners, steel saddles or other devices approved by the Comptroller.
