How to read structural steel drawings meticulously and precisely
In order to read a construction drawing, you must read the steel structure drawing in advance. When reading, specifically considering each part of the structure is essential to be able to understand the content of the drawings accurately. Here are some tutorials from BMB Steel to show you how to read steel structure drawings correctly.
A structural drawing is a technical plan describing how to construct a building, factory, or industrial plant. It is similar to a road map providing guidance on the construction process. Architectural drawings often precede structural drawings. In addition, in some cases, structural drawings are based on architectural drawings.
Structural steel drawing illustrates the connections of steel materials used in construction. It guides contractors to choose building materials. Fundamentally, the steel structure drawing shows the positions of each steel structure material used in the building.
The main components of steel structure drawings include:
It is significant to read and understand the guideline of each structural design drawing. After reading, you need to understand the following factors:
When reading actual layout drawings, you need to pay attention to the following:
Structural layout drawings include structural views, sections, and standard drawings. It is crucial to understand the structural form, plane position, and height of the main components. Besides, combined with architectural drawings to understand the situation of the position and the height of each structure.
Afterward, it is vital to classify the main components by combining section, standard, and detail drawings. Simultaneously, you need to find out and understand the similarities and differences between the component structures and their embedded parts.
First, check the position, elevation, and quantity of the parts on the structural plane in accordance with the detailed drawings and whether there are any conflicts in terms of elevation, position, size, or not.
Understand how to connect components to determine whether position and elevation can be guaranteed or any conflicts with other components. Understand the details of the accessories and steel bars in the structure. Verify the above content in conjunction with the material table.
Finally, summarize the building structure drawings, organize the documents, check the previous questions and make suggestions.
Engineers and architects often work together while designing structural steel drawings to ensure that the intentions of the architect and the owner will be agreed upon. To understand this through the drawing of steel structures, you need to practice the following skills:
It is essential to understand the ratio or the actual size of the factory building and industrial plants built. Every unit of measurement on the drawing changes to a larger unit in real life.
In practice, it is pretty tricky for a newbie or inexperienced person to estimate or visualize different scales. To get the scale precisely, the first step is to understand the type of scale. If impossible, you can ask your engineer to explain and assist you in visualizing and understanding the practical dimensions.
Learning the symbols’ meaning on steel structure drawings plays a critical role in reading the drawing. For example, symbols representing sections or heights, common signs include circles, rectangles, triangles, etc.
Most symbols have a particular explanation in different technical fields. Engineers have preset descriptions. Therefore, in order to decipher symbols, you only need to memorize and understand their interpretive meaning.
This is a particular type of symbol on texture drawings. Icons are usually placed in the margins of the drawing. They provide additional information regarding construction. For instance, you can use the note icon to indicate where two steel materials are connected.
The circled numbers are the information on the mentioned page. It only informs you that there are other details discussed in a separate section of the drawing. The scales used in drawings are often so small that they cannot be explained in particular within the pages of the drawing. Therefore, it would make sense if any detailed explanation was done somewhere else. A circled number draws your attention to this. When you see a circled number, you should follow it to the correct page with details.
Abbreviations are as abundant as symbols in structural steel drawings. Engineers use abbreviations as regularly as symbols.
It is unnecessary to learn all the acronyms and their meanings. However, you can learn the general ones. When you meet unfamiliar people, you can consult an engineer for guidance.
Hopefully, this information from BMB Steel will assist you in working and becoming proficient at reading professional drawings for a short time. Follow the suggested steps from BMB Steel to improve your skills.
