What else was achieved?

Post by shamimhasan07 »

Alexander Osipov from the BIM Academy presented his report with such a loud title at the BIM breakfast, which took place on December 2.

What BIM specialists encountered
What else was achieved?
What's the bottom line?
The general theme of the meeting this time was designated as “EOM and CC sections in BIM”.

Right at the beginning of his speech, the speaker noted that although the situation described in the title of his presentation seems true at first glance, in practice everything turned out to be different.

What BIM specialists encountered
On one large project, which is still under construction, there was a requirement: BIM is needed. Because some deadlines had already been missed, problems arose due to the human factor, and it was necessary to promptly make changes to the documentation.

Main tasks
The first task that faced the specialists of the BIM Academy was to create a tool for calculating the total amount of cable to be laid in a building.

The approach to its solution turned out to be quite standard: first, the initial data were prepared (technical specifications, architectural, technological and engineering models and regulatory documentation), then they began calculating and graphical processing of the data and, finally, the documentation was prepared.

As a result, the BIM Academy came to the conclusion that it is possible to create a server part where calculations will be performed, and a “workplace” with a plugin where various consumer connection schemes will be implemented. The G-SMART Electro software product was chosen as such a workplace.

There is a controversial situation with the module for calculating main sections . Different specialists use different methods for calculation: some use the Electrical Installation Code, others use the State Standard. In such cases, Alexander Osipov recommends choosing one option at the beginning, and then adding other methods during development.

Because, according to him, it is still necessary to create a conditional calculation module based on the data that is entered into the elements of the model.

Another of the main tasks was to build a schematic diagram . Alexander Osipov showed how specialists from the BIM Academy managed to synchronize the CIM and the schematic diagram, noting that many electricians prefer to use the diagram rather than the model.

Power shield calculation module
After some time, the BIM Academy realized that after one calculation, there was a need to select machines and arrange them so that they could be automatically recalculated and a new single-line diagram could be created.

To avoid manual approach, we created the function "Standard floors". Thanks to it, the placement of switching protection devices can be performed only on one analog floor and then select on which other floors the automatic connection should be performed.

Tray filling analysis
A situation can often arise in which an electrician cannot determine how much load needs to be placed in the trays - Alexander Osipov noted that he himself has encountered this more than once.

When G-SMART Electro is working , this information is generated automatically and becomes available for viewing immediately after the cable is laid in the channel in the model. To clearly see how this function works, watch the scribing.


As a result, the BIM Academy team was able to complete a variety of project tasks across a variety of categories:

Modeling (building cable lines in the model, placing protective devices in panels, placing clamps on risers, mapping parameters, editing built routes)
Calculations (calculation of voltage drop, calculation of short-circuit currents, selection of cable line cross-section, selection of protective device rating, load balancing)
Design (generation of schematic diagram, generation of single-line diagrams, export phone number italy of cable log to Excel)
What's the bottom line?
What other tools are there?
In addition to the plugin used in the BIM Academy, there are many other tools for working with building electrical networks:

nanoCAD BIM Electro: for designing and modeling EM, EO and EN systems
Model Studio Cable Management, Lightning Protection, Panel Layout, Electrical Circuits: all products are based on nanoCAD and dwg format
Where can I find the requirements?
Many requirements are listed in the EIR (Customer Information Requirements). Alexander Osipov gave several examples, emphasizing that there is often a requirement to install large-sized equipment, and sometimes even a requirement to route all low-current sensors.

How to motivate to use BIM?
Alexander Osipov refuted the opinion that specialists have no desire to use digital tools for modeling electrical networks. According to his team's experience, requests for a high-quality calculation module appear everywhere. In addition, many are interested in libraries of electrical equipment and plugins that allow for faster design.
