General arrangement (G/A) drawings are critical for viewing the overall configuration of a mechanical unit (building, skid, plant, etc.) They also display an overview of key structural elements of a piece of equipment, structure, or assembly. Depending on the complexity of the object, General Arrangement are likely to require a number of different projections, such as sections, plans and elevations. They may also be spread across several different drawings.
General Arrangement are generated when the following are required:
- Assembly drawings of process equipment (vessels, piping, valves, and instrumentation).
- Plan drawings (foundation, floor, deck layout and anchor bolt plans).
- Multiple views of one drawing, counting the entire model or a part of it.
- Erection elevation drawings.
- Information from model views, including 3D views.
Methodology
Once the process flow diagram is complete and the P&ID details are nearly complete, the process of producing a General Arrangement begins. After determining the primary processes, the engineer or designer creates a 3D model that serves as the foundation for the General Arrangement drawings. Because the model and first-pass drawings are frequently started by a designer before all the technical calculations are completed, they are conceptual. In a few instances, the General Arrangement is created without the usage of a model.
Accessibility and build alternatives are provided in general arrangement drawings, which are not build-ready but serve as a starting point for further discussions with clients, engineers, fabricators, and other stakeholders. A 3-dimensional isometric view, as well as plan and elevation views, are usually included. Every drawing has a title block that provides important details like the project number, client, release date, drafter, and checker.
Structural General Arrangement drawings play a key role in civil engineering construction. To complete your construction projects on time and to the necessary level of precision, you will need precise and detailed construction drawings generated in a timely manner, to keep the project going forward.
