Reinforcing Steel Inspection San Diego
What it is: Re-bar are steel bars of various diameters and lengths which have steel ribs that add to the bonding value of concrete for adhesion and additional strength. Reinforcing steel and concrete are bonded together by a mechanical connection. This provides the tensile properties which adds another element of strength to the concrete. Re-bar steel has letters and numbers which are stamped on the bar from the steel mill. This shows the mill produced, bar size, type and grade of steel. In addition, information provided gives the designation number and fraction diameters which are most commonly produced #3 = 3/8”, #4 = ½”, #5 = 5/8”, #6 = ¾”, #7 = 7/8”, #8 = 1”, #9 = 1 ¼”, #11 = 1 3/8”, #14 = 1 ¾”, #18 = 2 ¼. When freshly mixed concrete is placed over secure and strategically placed reinforcing steel the product becomes reinforced concrete.
What it does: Reinforcing steel which is placed within the concrete allows the concrete to be elevated as re-bar steel provides tensile strength. The concrete in contact with the deformed or ribbed reinforcing steel creates a strong mechanical bond. Adding reinforcing steel to the concrete provides the strength of hydration between water, cement, sand and rock in addition to the mechanical strength of concrete bonded to the reinforcing steel. Adding reinforcing steel to the concrete will immensely increase the strength. As a composite structure it can be three or four times stronger.
If the concrete was elevated and it did not have reinforcing steel it would collapse.
If our bodies did not have bones we would collapse.
What we do: As a special inspector verified by the city of San Diego it is my responsibility for checking placement of the reinforcing steel at the project site. The jobsite shall be in accordance with the city’s reviewed and approved plans. I provide and execute a thorough checklist of steel inspection. In addition, it is my responsibility to observe and document that the reinforcing steel is clean, secure and in place. This includes but is not limited to lap, bend, type, grade, condition, size, chair heights, clearances between bars, cover and earth material and then documented.
