When a construction project is executed, it is very important to prepare an accurate structural drawing for the proposed building. The strength of a building depends on the robustness of its internal structure. Structural designs and drawings are generally prepared by structural engineer. When these designs and drawings are prepared, any kind of error can affect the actual construction process.

What all drawings structural engineers mainly create?

Structural drawings: These drawings include all the information related to the building structure. This drawing also helps professionals to conceptualize how the building structure will be built. Once the drawing is completely prepared, it is used for load analysis.

A structural drawing mainly shows:


Dimensions of structural components, parts and pieces

Size and jual besi siku semarang shape of all components

Material types

Connection details among various parts

Installation process of each structural members

Dimensions and levels of all concrete members

Elevations, sections and plans

Location of all structural members, connections and holes

Length, shape and number of each type of reinforcing bar
Reinforcement drawings: These drawings generally describe and locate all reinforcement in relation to the completed concrete surface and to any holes or fixings. Reinforcement drawings are mainly used for steel fixers.

Standard details: The engineers and detailers often find that some details occur regularly on a variety of tasks.

Standard details consist of:


Standard notes

Concrete box culverts

Column bases and pile caps

Expansion/construction joint details, etc.
Record drawings: When a building structure is constructed, it is not possible to develop everything exactly same that have been drawn in the original CAD drawing. Some changes always occurred on the site for avoiding any kind of complicated situation. The prime purpose of record drawing is to include all the changes (which have been made during actual construction) within the original drawing in a precise manner. The changes are generally shown using redline.

Once the reinforced concrete structure is completely constructed, the original CAD drawing is modified for showing the changes effectively. CAD assists professionals to make the changes within the digital files easily. After including all the change accurately within the drawing, a revision letter is prepared that describe all the amendments clearly. This letter is attached to the original CAD drawing.

When engineers prepare all the above drawings, they strictly follow the location specific structural standards and codes. Hence, the structural drawing and other drawings are equally important for constructing a building structure accurately.
