Know how to use in construction process: Fabrication Drawings & BIM Modelling

Fabrication Drawings are often overlooked, but they are one of the most important steps in complex construction. The drawing will have detailed how the elements are built, assembled and installed. Good Fabrication will give the on-site contractor the exact measurements and the number of elements needed to complete the project. If manufacture is inaccurate, this will cause delays and damage on site.

For the proper specification of the building, structural engineers create the drawings by hand. These drawings show the virtual plan of the building and it is transmitted to a contractor or a builder. After approval, drafters begin the process to use for future building construction. These drawings display vital information about supporting elements such as beams, columns and trusses.

Types of Fabrication Drawings

When working with steel structures, you can expect to receive three types of Fabrication Drawings. Each plays an important role in the construction process and only one complex project will require the three drawings. Know that even these relate to the type of drawing and not to the quantity. More than one drawing in a variety of views will be required in each type. The mark of a good Fabrication drawing is the presence of only the necessary information.

1. Drawing in one part: These drawings focus on complex details of the work. They contain specific information for the cut, dimensions and weight of the materials needed.

2. Mounting Diagram: It tells the welder how to assemble all the parts. They include information about finishes and a nomenclature.

3. General Arrangement Scheme: This is the master plan. It shows how all the pieces fit together and contain several drawing angles.

BIM improves team collaboration and workflow efficiency
Building Information Modeling (BIM) is a range of digital information storage and manipulation systems used to facilitate the construction and maintenance of buildings and facilities. The phrase is used to cover everything from 3D models to digitized architectural plans. However, BIM is much more than that. It goes beyond the mapping of physical space and includes built-in features and cost measures in a plan.

The real potential of BIM Modelling, however, lies in a new approach to architectural data storage. Rather than being based on graphical representations, the BIM contains information in a database. This data can then be viewed and edited flexibly, providing a single, " source of truth" dataset that can be edited collaboratively and editable for use by all teams and can track a building throughout its lifespan.

In the days before BIM, it became difficult to get a truly global view of a project - with thousands of unrelated documents in play; it sometimes took years for design teams to see the forest in place of trees. By bringing all project documents together in one view, BIM enables teams to collaborate and communicate more effectively.

BIM produces 3D models of drawings. This expands data accessibility and allows non-specialists to interact and even modify building designs. This is essential for customer pitching projects and helps building managers gain valuable information about the structures they are responsible for maintaining after construction. BIM Modelling follows a building throughout its life and continues to add value to those who interact with it for years.
