Responsibility of the Rebar Detailer Detailing and Rebar Placement drawings

In the rapidly growing industry of steel structure, it is essential for any contractor or structural engineer to know the basic function of reinforcing rebar placement drawings, duties of a reinforcing steel detailers, method of making drawings and placement responsibility of the steelworkers.

The ASCE (American Society of Civil Engineers) Manual on the steel design guidelines has the distinct difference between the two types of rebar detail drawings – drawings for reinforcing steel placement and shop drawings for components. Although many engineers / processors still of the opinion that structural steel shop drawings and reinforcing steel drawings are identical in nature, purpose and scope, which is not true in many practical ways!

A reinforcing steel detailer is generally a subcontractor of steel fabricators. The details are researched design data shown on the plans and project specifications, details or record members for a certain portion of the structure required. These special pieces are then welded or registered under the plan to detailed placement drawings.

Typical of reinforcing steel requires the ACI (American Concrete Institute) Building Code, the implementation plans to show location and size of all structural components and reinforcement, place and type of welded splices and mechanical connections anchorage length of reinforcement.

Normally design information in terms of structural dimensions, the quantity of reinforcing bars and bar size specific. This typical data is not specific enough to be able to cut to length, fabricate, ship and install reinforcing bars directly from the design drawings. Therefore, the requirement that should detail / placement drawings are supplied. The details have good math and visual skills with additional knowledge of CAD design and drafting systems to provide detailed drawings for a low-cost manufacturing.
