BIM (Building Information Model) is a digital representation of physical and functional characteristics of a facility that extends beyond just building geometry.

10%
Reduction in documentation errors

15%
Material cost savings up to 15%

30%
Construction time reduction up to 30%

Key advantages of information modeling that can be decisive when justifying its use:

1. Minimizing design revisions
2. Direct demonstration of information models, emphasizing the connection between 3D models and drawings during technical meetings with the client
3. Ability to obtain accurate quantities and link them to delivery schedules and estimates
4. Significant reduction of delays caused by material shortages and searching for alternative technical solutions
5. Demonstration of overall maturity and current level of information technology development (automation, detailing, quality checks, advanced developments)

The main documents when working with clients within the information model framework are BEP (BIM Execution Plan) and EIR (Employer's Information Requirements). A detailed BEP helps clients understand the contractor’s competence and establishes transparent project development.

n addition to BIM design innovations, we also use VR visualization alongside traditional renders. Detailed BIM-based models allow specialists to quickly prepare 3D models and create VR tours. The connection between BIM models and visualization models enables fast and accurate changes during client coordination.

Advantages of VR over traditional visualizations:

1. Ability to show the object from all angles, not just selected viewpoints
2. Navigation through VR tours helps viewers better understand spatial relationships
3. Showing all details without multiple viewpoints
4. Interactive model exploration in any direction

At Concept Stage - ability to obtain accurate technical-economic indicators thanks to:

• Structural system consideration
• Utility and shaft integration
• Evaluation of more design options

At Design Documentation Stage - ability to avoid discrepancies between documentation sections thanks to:

• Automated clash detection reports
• Multiple specialists working simultaneously in unified model environment
• Faster technical task coordination in 3D model

At Construction Documentation Stage - ability to obtain complete information model thanks to:

• Quantity takeoff accuracy matching construction needs
• Reduced design errors
• Faster decision-making and approvals
• Shorter construction timelines
• Lower construction costs

At every project stage, BIM technologies enable economically beneficial construction decisions.

The BIM model lifecycle begins with schematic design. Even at this stage, you can get massing studies, check ergonomics, and "walk through" the future building. You can obtain quantities of reinforced concrete, walls, partitions, windows, doors, floors, and facades with up to 90% accuracy for cost estimation.

BIM models at these stages help eliminate material calculation errors for glazing, concrete, masonry, facades, finishes, MEP systems, and more. It solves spatial coordination issues between structural and MEP systems. The BIM environment can significantly accelerate documentation updates during construction observation or material substitutions.

Using BIM technologies, we can create models of various facilities, even based on existing design documentation. During construction, the initial model undergoes significant changes, requiring updates at each stage, including during facility operations.

Building Information Modeling (BIM) not only improves design cost-efficiency and profitability but also enhances safety management. Its application during operations reduces maintenance costs, minimizes overtime work, decreases equipment downtime, improves staff productivity, ensures high operational quality, and enhances occupant safety.
