In the world of modern architecture and construction, Building Information Modeling (BIM) has become one of the most important technologies reshaping the future of the construction sector. This technology is not merely a 3D engineering drawing program; it is an integrated system that connects design, execution, and operation in a single digital model.
What Is BIM Modeling and Why Does It Matter for Your Project?
Building Information Modeling is the process of creating and managing a comprehensive digital model of a building that contains all of its engineering, design, structural, mechanical, and electrical information. BIM differs from traditional 3D drawing in that it carries live, dynamic information for every element in the building, from the type of concrete used in the foundations to the elevator model on the tenth floor.
In Saudi Arabia, BIM has become a core requirement in major government projects such as NEOM, Qiddiya, and the Red Sea Project. Government authorities have begun requiring the delivery of BIM models at specific LOD levels in order to obtain permits.
BIM Levels of Development (LOD) and What They Mean
The Level of Development is a measure that defines how detailed the model is:
LOD 100 – Preliminary Concept
The preliminary studies stage. The model contains masses and spaces without precise details.
LOD 200 – Conceptual Design
The model contains approximate elements with general dimensions defined. Suitable for the preliminary design stage.
LOD 300 – Detailed Design
The model contains precise details with actual dimensions. It is considered the standard level for most projects in Saudi Arabia.
LOD 400 – Execution Design
The model is ready for fabrication and installation. It is used in complex infrastructure projects.
LOD 500 – Operation and Maintenance Model
The model as actually built (As-Built), used for facility management throughout the life of the building.
BIM Benefits in Saving Cost and Time
- Clash Detection: 70% of the clashes between electrical, mechanical, and structural systems are detected before excavation, saving millions of riyals.
- Accurate Quantity Takeoff: Accurate bills of quantities are extracted automatically, instead of manual calculations that may carry an error margin of up to 15%.
- Construction Simulation (4D): Studying the construction sequence over time and identifying obstacles before the excavator reaches the site.
- Cost Management (5D): Linking quantities to prices in real time and monitoring cash flow.
The Most Widely Used BIM Software
At Kayan Smart, we use the complete suite from Autodesk:
- Revit for architectural, structural, and mechanical modeling.
- Navisworks for clash detection and simulation.
- BIM 360 for cloud-based collaboration between teams.
- Civil 3D for infrastructure and road design.
How Do We Apply BIM in Our Projects?
Our methodology at Kayan Smart begins with developing a BIM Execution Plan (BEP) that defines the required level of development, delivery standards, and responsibilities. We work in line with the international ISO 19650 methodology for information management in construction projects.
In a recent residential complex project in Riyadh, we used BIM at LOD 400 and discovered more than 350 clashes between systems before execution began. Had they been discovered on site, they would have cost the project more than SAR 1.8 million in additional costs.
The Future of BIM in Saudi Arabia
With the launch of Saudi Vision 2030 and the giga-projects, mastering BIM has become a necessity rather than a luxury. The Saudi Authority for Industrial Cities and Technology Zones (MODON) and the Ministry of Municipal and Rural Affairs have begun requiring BIM models in major projects.
At Kayan Smart, we continuously invest in training our team on the latest versions of Revit and obtaining certified credentials from Autodesk. Our goal is to be the first partner for investors and developers in transforming their projects into smart digital models that ensure quality and efficiency.
