Checking the steel shop drawings are considered to be very important to avoid the elements that may cause adverse impacts on the building structure. It is not possible to interpret the steel shop drawing. These drawings are specialized, precise and provide the instruction to the fabricators. Thus, these elements make it important to check the shop drawings, as the entire geometry of the building is controlled by the steel Detailer. By checking the drawings, it reduces the chances of errors to the maximum extents.
How Qualified the Steel Shop Drawings Checker shouldbe?
The professional checker who is involved in checking the drawing must be:
• Experienced in all procedures of steel fabrications
• Must have strong geometry skills
• Must pay high attention to all details
The checker may not necessarily be a drafts person, however, must be skilled in ensuring a perfect drawing. He must also pay attention to build-ability of the structure while checking.
Approaches of Steel Shop Drawings checking:
Some of the approaches of steel shop drawings are;
• Check primary datum of the building and the checker may need to create a layout for this
• Span
• Bay spacing
• Roof pitch
There are also some other elements that the checker need to check and they include:
• Secondary building datum
• Bracing set out
• Bracing member sizes
• Column and rafter
• Bolt size / plate size
• Purlin member size / spacing
It is important to check every number. “Drawing mark-up method’ is widely used for checking all the details of the shop drawings. The “Threefold Chord” checking method is also widely used for shop drawing.
