We provide a full set of Fabrication Drawings to bridge the gap between Design and Fabrication
What are Fabrication Drawings?
Fabrication Drawings are usually used for 1 off’s or per job/project bases (compared to Manufacturing Drawings).
The fabrication drawing is a specific type of detail drawing. Some fabrication drawings are virtually assembly drawing e.g. when a number of items are assembled together as a fabrication. The fabrication drawing generally includes a material parts list identifying all of the materials used to build up the fabrication. All weld details are included using the standard symbolic representation of welds as shown in AS/NZS 1554.1. All of the materials should be identified in accordance with the relevant standards and codes.
They are mainly used in:
- Structural Steel
- Sheet Metal
- Architectural Steelwork
The drawings (similar to Manufacturing Drawings) are split into 2 main categories:
1. Part Drawing
These drawings detail the part itself that require fabrication for use e.g. by the welder. They also indicate the material & surface finish.
The drawings should include the following information. (They should however not show more information than is required.) :
- Material Specification
- Linear Dimensions including Tolerances
- Angular Dimensions including Tolerances
- Weld Location & Type
- Flat patterns including bend lines
2. Assembly Drawing
Depending on the complexity, Assembly drawing are often structured into a Top Level Assembly and Sub-Assemblies. This is to give more clarity on the full product. Assembly drawings should include:
- All Sub-Assemblies used within the assembly
- All parts to be fabricated
- All bought in parts including their specific part numbers, manufacturer or supplier
- Fixings such as Bolts, Nuts, Washers etc.
- Bill of materials (BOM) showing a full list of all parts
- Cut Lists stating length and angles
- The drawings should be illustrated in a way to clearly show how the Fabrication fits together. This should/could include several views (Plan, Top, Side, Isometric etc.) and Exploded Views
- Additional information that might be required such as Weight, assembly instructions should also be included if required.
It is important that good quality drawings show all the information that is required, but no more than needed. An example is to many dimensions or to many views.
What Fabrication Drawings do we offer?
We offer full set of Fabrication Drawings for a range of industries. We believe that in order to produce good quality fabrication that will enable an excellent installation on site a certain amount of coordination is required between all parties involved.
We are used to coordinating with steel manufacturers, architects and structural engineers to create General Assembly Drawings and the subsequent detailed drawings showing connections, holes etc.
Our service prides itself in working closely with all parties involved to ensure any queries get raised and answered prior to fabrication commences. We are therefore always willing to visit site should this be of advantage.
What information do we need to create Fabrication Drawings?
This depends on the industry involved.
For Structural Steel Fabrication Drawings (including, Stairs, Ballustrading, Architectural Steelwork etc.) we usually work from the Structural Engineers Line Drawings in conjunction with the Architectural Drawings. We would normally visit site to check any potential clashes.
How much do Fabrication Drawings cost?
All are Fabrication Drawings are usually quoted on a fixed price basis as we are normally able to quantify the work easily.All we need is the Structural Engineering Drawings or Architectural Drawings in order to provide a fixed price.
2D Drafting Design Tools and Software
Our Expert Engineers & Drafters are versatile enough to use any software that your process might require. We have successfully managed Drafting and Design projects involving software such as AutoCAD, ArchiCAD,Solidworks, Revit Architecture, Architectural Desktop, Microstation, and 3D Studio Max.
