Fabrication shop drawings are necessary to manufacture steel structures. These are drawings that are created by steel fabricators and are provided to contractors for their use. It enables them to know the details of various kinds of constructions like cold-rolled steel, stamped steel, forgings, stamped & welded joints, etc.
The fabrication shop drawings form the critical portion of steel structure making. They identify the appropriate joint locations and detail the size of each of them. The drawing shows the end product, it helps in the proper calculation of material costs, the number of materials required for each work. Drawings give full information of all materials required for a building structure like cold-rolled steel, stamped steel, forgings, stamped & welded joints, etc. It also enables the fabricator to determine the required configuration of building structure and know the kind of material to be used.
The purpose of fabrication shop drawings is not only to give accurate dimensions for construction projects, but they must also be precise. The accurate drawings must include all details which are of vital importance for a construction project, such as the location of building corners, walls, windows, roof, ventilation system, electrical points, foundation, slab, & column connections. These detailed drawings are essential for quality control of equipment and material used in a manufacturing process.
Fabrication shop drawings are generally required before metal structures are designed, built, or fabricated. For example, steel manufacturers usually require detailed drawings of their processes before assembling any metal structures. In the case of a construction project, a well-designed factory may help save considerable time and money. Therefore, fabrication shops need to have well-designed and detailed drawings for each stage of construction.
Generally, fabricators use computer-assisted design (CAD) programs for fabricating designs. This program is capable of providing accurate measurements and accurate specifications. Computer-generated fabrication (CAD) has made the entire process of fabricating metal and non-metal products very easy.http://www.djsteelengineering.com/steel-shop-drawings.htmlrequires accurate measurements and accurate specifications. Fabricators, therefore, are always in need of accurate dimensions and specifications from their clients. The use of CAD programs makes this task easy for fabricators and contractors.
Generally, fabrication shop drawings include four major sections: pre-fabrication, molds, shop framing, and fabrication. Pre-fabrication drawings show the conceptual design of the entire construction process. This shows complete details of size, shape, weight, dimensions, and materials to be used in the construction process. These drawings can facilitate the manufacturer to choose the appropriate type of material, type of tools and techniques to be used for the construction process.
Molds drawings illustrate the requirements of different kinds of molds. It includes information such as required temperature, the required quantity of material and specific height, width, length, and other parameters. These data are crucial for the manufacturer to choose the right type of mold for the product. Whether choosing acrylic or cast aluminum, PVC, or other material, great fabrication drawings help a fabricator in making informed choices and ultimately getting the best product possible.
Fabrication shop drawings are usually produced as digital electronic files. These are large and most of them require a large computer to read and process the data. To reduce the size of these files, they are usually output in PDF format, which is also a very portable file type.
In the case of the CAD program, the files are produced as digital images in three dimensions. This makes them easier to manipulate and process. Unlike the traditional manual drawings, the dimensions in CAD drawings are precise and can be easily manipulated by any CAD-CAM computer. The program produces detailed drawings with all relevant information such as materials, sizes, angles, depths, currents, and other physical quantities. In addition, the program produces the most accurate and comprehensive data set for every piece of building material. Great fabrication shop drawings provide for easy and quick measurement and constructional accuracy, and so it is widely used by fabricators and other industrial designers.
The on-site fabrication drawings can be used for many purposes such as site investigations, site planning, and design, site enhancements, site investigations, contractor billing and collection, pre-construction audits, and numerous other purposes. The on-site fabrication drawings are more accurate than off-site drawings, as they are produced on the spot without any delay due to travel or other problems. They also save the client lots of money. Most clients find that the cost of the construction project is reduced tremendously with the use of these construction drawings. They also help in avoiding legal hassles and delays.
Most construction firms use these detailed drawings for various purposes, especially for pre-construction projects. These fabricators and construction firms can produce accurate steel components that meet the requirements of their customers. Since the on-site fabrication drawings are more accurate and complete, they are used for pre-construction and pre-delivery jobs, as well.
