What is BIM

Technologies are not static in the sectors of design and construction as well as architecture. They develop and correspond to complex technological objects of architecture. Basic knowledge and standards come from the past decades are not so popular yet. Nowadays architects and designers significantly save time and money inserting in their tools Building Information Modeling.

BIM technology is a process at every stage of which the interaction of software for design is done faster, more accurately and cheaper. As a result, we get the model with the most detailed structure described.

3D models and their construction greatly simplify some stages of design. It is the perfect solution when interacting with BIM modeling. Detailed description of the objects, what they consist of, materials, etc., are described in the model. This information is available to all specialists in electronic form.

BIM Advantages over CAD

The main difference between the old approaches to design development and BIM is the interaction between specialists at the level of complete information models. In fact, we get not just drawings, but information about what kind of model it is and what information it contains.

Any changes in the drawings, sections, etc. are displayed in all views of the BIM model. It was achieved thanks to use of centralized data storage. Such approaches reduce the terms for the design documentation development, and also exclude the appearance of errors, automatically coordinating all of their types.

BIM models contain not only data on the architecture of the design. They also contain information which describes engineering networks, structural elements, and environmental design.

The possibility at any time to determine the estimated cost of the design, labor costs and financial indicators – all these are components of the BIM design.

Using the data embodied in the BIM model, we not only get usability at the stages of design creation and construction. We also can significantly reduce the cost of operation which is more than implementation.

Detailing of the BIM model

Information model LOD 500 (Level of detailed) has a level of detailed which allows working out the operational model of the building in detail.

Thus the quality of service and operation goes to a new level. Thanks to automation and competent study of the elements, it becomes possible to detect and correct faults on time.

Information model LOD 500 LOD 400 LOD 300 LOD 200 LOD 100 (Level of detailed)


LOD 100 – detailing, which includes forming elements; it forms a conceptual representation of the model.

LOD 200 – detailing, which has an understanding of the building’s shape and size, building’s approximate placement; it forms a pre-design solution.

LOD 300 – stage “Design documentation” describes the detailing at the level of belonging to the particular system; size and shape already have exact values.

LOD 400 – stage ‘Working documentation” has a level of display of clear links, exact placement and spatial orientation.

LOD 500 – operating level which shows all of the above parameters, but with specific actual rates of the size, orientation, etc.

Single operational system for object monitoring is the best solution when creating a BIM model. It provides monitoring of the terms for the equipment’s operation, notification of the need to replace the structure parts. If a BIM building model was created during the design creation stage, the maintenance service will have all the information about the building. All changes made during construction will be showed in this model. It itself will report on the need to replace the unit or equipment.

Cost of design error

Analysis of the life cycle of the structure shows that the design development takes only about 5% of all investments. However, high costs can result in mistakes made during design. Such mistakes can significantly affect the rise in the cost of construction and operation of the building.

Advantages of BIM design in V-Grand

V-GRAND engineering is a team of the best specialists. Our HV (heating and ventilation), EL (electricity and lightening), DS (design solutions), CN (communication networks), WS (water and sanitation), AS (architecture solutions), MP (master plan) specialists, quality control guru and managers have more than 5 years’ experience. V-GRAND staff development guarantees the knowledge and skills required to build a BIM model.

Specialists of V-GRAND engineering use modern software to build the BIM model. Work takes place on our own computing power and is controlled by the Planfix control system. It provides convenient and informative interaction between specialists of the design.

Using standards for BIM designing, design coordination, creating element of collections we developed our own algorithm of actions at all stages of design in BIM. The team of V-GRAND designers guarantees high-quality technical solutions and documentation with the best results and in a short time.

V-GRAND engages modern services for interaction between team members.

We choose the appropriate strategy for the design development. That’s why at the stage of harmonization of all processes, first of all, we agree technical solutions.

Equipment and materials also should be added in the information modeling.

Orthogonal forms are presented in PDF or DWF. Presentation in the cloud is also possible.

At the end of the model development, the customer receives the drawings and the model in RVT and PDF.
