Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 3766 was prepared by Technical Committee ISO/TC 10, Technical product documentation,
Subcommittee SC 8, Construction documentation.
This third edition cancels and replaces the second edition (ISO 3766:1995) and ISO 4066:1994, which have
been technically revised.

INTERNATIONAL STANDARD ISO 3766:2003(E)
Construction drawings — Simplified representation of concrete
reinforcement
1 Scope
This International Standard specifies the simplified representation and the characterization of reinforcement in
reinforced and in prestressed concrete for use in construction drawings. It also establishes a system for the
scheduling of reinforced bars, comprising
a method for specifying dimensions,
a coding system for bar shapes,
a schedule of preferred shapes, and
a shape schedule and bending schedule.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 128-23:1999, Technical drawings — General principles of presentation — Part 23: Lines on construction
drawings
ISO 10209-4:1999, Technical product documentation — Vocabulary — Part 4: Terms relating to construction
documentation
3 Requirements to reinforcement construction drawings
The construction parts shall be provided with the main dimensions, the concrete reinforcement shall be drawn
and all parts shall be represented unambiguously and clearly in scaled plans, elevations and sections. The
representations shall correspond with the indications in the structural calculations and should, where
applicable, contain all dimensions required for the construction of the members and the verification of the
calculations.
Drawings used for off-site casting and factory production are excepted from this provision.
Reference shall be referred to accessory drawings. For drawings modified later, all concerned drawings shall
be modified as well.
The following characterizations (general information and placement information) of the reinforcement bars
shall be given on the drawing:
required concrete strength class, the exposure class and further requirements to the concrete given in
reference standards;
ISO 3766:2003(E)
type of reinforcing steel and prestressed steel given in reference standards;
bar mark, number, diameter, shape and position of the reinforcement bars; distance between the bars
and overlap length at joints; arrangement, dimensions and development of welding points by specification
of the joining metal, jarring plates, position of the concreting gap;
type of the prestressing system; number, type and position of the tendons; number, type and position of
the tendon anchoring and tendon coupling; bar mark, number, diameter, shape and position of the
accessory not prestressed concrete reinforcement; type and diameter of the encasing tubes; specification
of the intrusion grout;
measures for securing the position of the concrete reinforcement and the tendons (e.g. kind and
arrangement of the bar chairs, as well as arrangement, dimensions and shape for the support of the
upper concrete reinforcement layer and the tendons);
the layer dimension c which derives from the nominal dimension c of the concrete cover, as well as
V nom
the allowance in design for tolerance ∆c of the concrete cover;
the joint development;
special measures for quality assurance, if required.
The following information on bending the reinforcement bars shall be given on the drawing or on separate
documents such as a bar schedule:
if the shape coding system according to 6.3 is applied, bending shapes of the reinforcement bars shall
refer unambiguously to the shape numbers, hence the graphical representation may be unscaled;
single length, sectional lengths and, if applicable, bending angles of the reinforcement bars shall be
indicated (for typifying bending shapes, Table 5 shall be taken into account, and in every case the
reference standard mandrel or radii shall be represented on the drawing);
the mandrel diameters or radii.
Manufacturing tolerances shall be taken into account in dimensioning the reinforcement components, in order
to reach the desired concrete cover in the ready-made structure.
4 Placement information and representation
4.1 Reinforcement without prestressing
The representation and drawing conventions of concrete reinforcements without prestressing shall be in
accordance with Table 1.
