Why Is It Crucial To Have Accurate Fabrication Drawings? How BIM Helps In Achieving It?

 

What if Fabrication drawings are inaccurate?

 

One of the most critical phases of complex construction is fabrication drawings. These drawings would illustrate in detail how components are built, placed together and assembled. 

 

If inaccurate or incomplete fabrication drawings get delivered to the on-site construction team, everything can go awry. Below are the most common scenarios:

 

1.      The on-site manager could install the structure incorrectly if the drawings are vague or left open to interpretation. The project will no longer meet the same safety standards and will take additional time and equipment to disassemble. It is one of the worst challenges, and it takes the most to tackle.

 

2.      A sub-par fabrication drawing means that the contract will not get a proper understanding of the material requirement. In other words, the contractor will fail to analyse and order adequate supplies. A hold up due to a shortage of materials in the middle of building will cripple your tight timeline.

 

3.      Incorrect fabrication drawing could also result in harm to life and property. It won't have the intended structural integrity if a steel frame gets improperly constructed. Other parts of the construction site may collapse and destroy the foundation or, worse, injure a nearby worker.

 

How does BIM Modelling improve accuracy?

 

For development, design assessment and inspection of building materials, fabrication drawings are critical. Contractors, designers, engineers, and other stakeholders could enhance the design, fabrication, and development of the construction method using improved visualisation through BIM.

 

A BIM-based framework combines graphical and non-graphical data from BIM models and other external data sources to create drawings. As per the BIM geometric models, explicit algorithms automatically produce graphics on the drawing templates. Similarly, title blocks of the drawing templates get automatically filled with analogous non-graphical information.

 

Advantages of Building Information Modelling

 

Building Information Modelling (BIM) is a tool for digitally creating and handling holistic designs and layouts of a construction project. BIM structural modelling renders a three-dimensional representation. Apart from that, there are more planning-based (not physical) dimensions to a structure project. For instance,

 

• Facility and Asset management
• Time scheduling
• Cost estimation
• Sustainability

 

BIM structural modelling eases the related complexity to make a strong building structure. It aims to decrease prices and efficiently raise profit in the industry. Elmasry Steel Design and Detailing uses BIM modelling in diverse fields such as commercial, housing, manufacturing, educational, health care etc. for different forms of building. We facilitate modellers to employ state-of-the-art software to develop a precise 3D model. 

 

Besides building frameworks, BIM software can also help to develop structural 3D models of various portions of a structure.

 

Conclusion

 

Engineers generally used paper for drafting or designing structural components until the computing revolution began. It was a tedious and time-consuming task. Retaining a high level of accuracy was also a challenge in making sketches. By having immense advantages over the constraint of paper and CAD drawings, BIM modelling has made model designing easier for engineers.

 

Digitised BIM modelling in fabrication helps to obtain holistic workflow efficiency enhancement. It maximises the use of capital and talent, thus improving the quality of work.
