electricity supply is often forgotten

The main topic of the February BIM breakfast was the use of TIM/BIM in projects for the construction of linear facilities and transport infrastructure facilities.

The second topic was well covered by one of the speakers in terms of tools that specialists still lack.
However, the list of transport infrastructure objects is far from one item. And phone number location lookup canada successful experience in modeling such objects already exists. For example, power supply networks. This is what BIM manager Ksenia Gryaznukhina from GC "Samolet" talked about at the end of the event.

According to Ksenia,
"If we look at the consolidated plan of utility networks, then electrics are only in fourth place after the heating network and the NVK networks. Accordingly, we have a very small corridor left to lay the electrics."
At the same time, modeling of electric networks was complicated by the diverse geometry of cables, their multi-level arrangement, differences in the cross-section of cables in one trench, etc. And, of course, the need to adjust the model in the future - no one is completely immune from errors. Therefore, it was necessary to create a model that would be easy to change.
Through the eyes of a designer
Having defined the range of problems, BIM managers at Samolet decided to assess the problem from the point of view of preparing design documentation. Meetings were organized with designers, after which managers identified five main sections and the amount of labor costs that go into them:
Calculations
Explanatory note
Planned position of cable lines/EN supports
Section of trenches
Statements with volumes
As a result of the analysis, it was determined that the greatest amount of resources was spent on planning cable lines and placing lighting poles, drawing up statements and performing calculations.
Through the eyes of a BIM specialist
For the BIM specialist from Samolet, the process of modeling electrical networks consisted of four blocks:
Creation of model elements: cable lines, pipe blocks and lighting supports
Filling elements with appropriate attributes
Automate individual processes using C#, Python scripts and Dynamo software
Assembling the consolidated model in Navisworks and checking for collisions
The solution lay in automation
Having received two points of view on the process of creating power grid models, Samolet decided to cross the vision of a BIM specialist and a designer in order to find the best way to reduce labor costs.
The first thing that the managers decided to focus on was the format in which designers currently produce PDF and DWG documentation. According to Ksenia, it was decided to make this task as convenient as possible for execution.
The second factor that was taken into account was the need to reduce the designers' labor costs. After all, it is known that in any commercial company, time is money.
The last thing that BIM managers did in the context of combining the two approaches was to draw up a clear technical specification based on the designers’ requirements. Among them, the most prominent was the wish to have a “red button” that, by pressing, they could automatically issue documentation that complied with all standards.
Ksenia Gryaznukhina emphasized that Samolet is actively striving to create such "red buttons". At the moment, automation in the company has been implemented in the following areas:
Plugins that automate the creation of model elements.
For example, a designer can display all types of profiles that are in a project with just one click of the mouse.
Plugins that automate the preparation of statements.
The generated statements were dynamic: when elements in the model were changed, the data in the statement changed automatically. The list of such statements included cable logs, specifications, VORs, and a statement of lighting supports.
