You get full control and rights to both the created models and BIM libraries, as well as to the data for project implementation.

BIM (Building Information Modeling) is building information modeling. It is not just software or the creation of a 3D model, but a comprehensive process and methodology for managing information about an object throughout its life cycle: from concept and design to construction, operation and demolition. The essence of BIM is to create a digital twin of the object, which is not just geometric 3D shapes, but also a database filled with data. Each element of the model contains information about its physical and functional characteristics, cost, materials and installation times. This allows you to consider the building as a single system where all elements are interconnected.
Why does your business need BIM ?
The implementation of BIM provides significant competitive advantages and economic benefits due to the following factors:
1. Budget savings and increased profitability The use of BIM directly affects the financial performance of the project:
Cost reduction: The introduction of technologies allows to reduce construction and operation costs by up to 30%. The error in estimating the cost of construction and installation works is reduced by 10–15% thanks to accurate automatic calculation of material volumes.
Increased profits: BIM is perceived as a long-term investment, capable of increasing net present value (NPV) by approximately 25% through risk reduction.
2. Reduction of implementation time The technology allows you to significantly speed up all stages of work:
Construction times can be reduced by 20–50%.
The time for coordination and approval of projects is reduced by up to 90%.
Variant design is faster (time costs for checking variants are reduced by 6 times).
3. Minimizing BIM risks and errors allows you to identify problems virtually before they arise on the construction site:
Collision elimination: The model allows you to automatically find the intersection of engineering networks and structures at the design stage, which reduces the number of errors in documentation by up to 40%.
Reducing the "human factor": Process automation reduces the impact of human errors during design decision making and calculations.
4. Efficient operation (Facility Management) The largest costs in the life cycle of a building (up to 70%) occur during the operation phase. The BIM model is transformed into an operational model (AIM), which allows:
Quickly find information about equipment and systems, reducing response time to accidents.
I can predict how much I will spend on repairs and purchase spare parts.
Save energy resources (up to 40–60%) by optimizing system operation.
5. Transparency and control BIM creates a single common data environment (CDE), ensuring transparency of all processes for the investor and the customer. You can track the plan-fact of work execution (4D modeling) and budget development (5D modeling) in real time.

The main difference is that a 3D model is a geometric representation of an object, while a BIM model is a database in which geometry is inextricably linked to information.
If a 3D model (CAD) is a digital analogue of a drawing and visualizes only the form, then BIM (Building Information Modeling) is the process of creating and using "intelligent" objects containing data about the physical and functional characteristics of a building.
The main differences can be grouped into the following areas:
1. Information richness (Geometry vs Data)

• 3D model: A set of geometric primitives (lines, surfaces, volumes) that create a visual image. This is a static representation, often called a “dead” model, because it carries deep data for analysis.
• BIM model: This is an object-oriented model. Each element (wall, window, pump) is a digital object that contains not only geometric parameters, but also metadata: physical properties, material, cost, manufacturer brand, installation time, etc. Geometry in BIM is only part of the information; the real value lies in the data hidden in the model.

2. Parameterization and relationships

• 3D model: Changing a single element (e.g. moving a wall) in a conventional 3D model often requires manual adjustments to all related views (plans, sections) and neighboring elements.
• BIM model: Elements are parametrically related to each other. For example, a “door” knows that it is in a “wall”. If you move a wall, the door moves with it; if you change the height of a floor, the walls are automatically extended. Any change in the model is instantly reflected in all drawings, specifications and views.

3. Life cycle and use

• 3D model: Typically used to visualize the design concept and check for geometric conflicts during the design phase.
• BIM model: Accompany the object throughout its entire life cycle: from concept and construction to operation and demolition. It allows you to model not only the form (3D), but also time (4D - construction schedule), cost (5D - estimate), operation (6D) and other aspects.

4. Functional analysis

• 3D model: Allows you to evaluate the appearance and check whether objects physically intersect.
• BIM model: Serves as a basis for engineering analysis and simulations. Energy modeling (BEM), structural calculations, lighting analysis, escape route modeling, and acoustic calculations can be performed on the basis of BIM.

In short, a 3D model answers the questions "What does it look like?", a BIM model answers the questions "What is it made of?", "How much does it cost?", "When will it be built?" and "How will it work?"

Investment in BIM should be viewed as a long-term investment that yields returns through cost savings, time savings, and quality improvements throughout the life cycle of the facility.
The payback and return on investment (ROI) in BIM can be characterized by the following stages and indicators:
1. The adoption curve (“J-curve”): first decline, then growth The implementation of BIM does not yield immediate profits. At the initial stage, there is a short-term decline in productivity:

• Productivity Drop: When switching to a new technology, organizations often experience a 25-50% drop in productivity. This includes the cost of software, hardware, and training.
• Recovery Period: On average, organizations take 3-4 months to return to their previous level of productivity. After going through this stage, more than half of companies report a productivity increase of more than 50%.

2. Return on Investment (ROI) Companies that actively track implementation effectiveness report very high ROI rates:

• The return on investment (ROI) can reach 300-500% of the initial investment.
• BIM is considered an investment capable of increasing the net present value (NPV) of a project by approximately 25% by reducing risks and the discount rate.

3. Time frame for obtaining economic effect

• Long-term effect: The real economic effect often becomes noticeable only after a few years of using the technology, since the “one-time investment” model assumes income over the following years.
• Early payback: With the right organization of work, the use of technology can become economically profitable and pay off at an early stage (design stage).

What is the payback? The financial benefit consists of loss prevention and process optimization:

• Error reduction: The error in estimating the cost of construction and installation works is reduced by 10–15%. The number of collisions and errors in documentation is reduced by up to 40%.
• Time savings: Construction times can be reduced by 20–50%, and coordination and approval time by up to 90%.
• Total cost reduction: Construction and operation costs can be reduced by up to 30%. For example, the use of BIM in water supply design can reduce design time by 27.7% and reduce the total investment cost of the project by approximately 2%.
• Change cost reduction: According to the principle known as the “McLeamy Curve”, major efforts and costs are transferred to the early stages (design), which allows you to avoid expensive rework during the construction phase, where the cost of changes is much higher.

Thus, although the initial stage requires costs and time for adaptation, investments in BIM pay off many times over by minimizing risks and rework in the later and more expensive stages of construction and operation..

LOD - Level of Development (level of model development) is a basic concept that everyone who works in a BIM environment inevitably encounters. Sometimes LOD is interpreted as Level of Detail (level of detail), but at BIM BUDOVA we adhere to the official and correct interpretation - Level of Development, that is, the level of development and reliability of the element information.

The BIM methodology is based on the fact that a building model consists of elements that contain data.
At the same time, a BIM element is not just a 3D object.
BIM elements can be:

• graphic objects (walls, columns, equipment),
• digital parameters,
• schedule planning,
• cost,
• lifecycle data,

BIM is not about geometry.
It is about managed information.
