Electric cable in the ground does it have to be according to the design?

Good morning
Gentlemen and ladies, the electrician will run the cable from the box on the pole to the switchboard at home. My architect guided the cable on the project so bizarrely that it runs in a zigzag pattern. One to the right, one to the left, it just doesn't make sense. I do not know if he did it while drunk or sober, I do not penetrate. The electrician said it was possible to run the cable in a straight line from the box to the house and it wouldn't be a problem. He stated that no one would check it anyway, because how? The cable will be buried around 30 cm on Tuesday and on Wednesday an excavator will arrive and it will fertilize almost 50 cm of soil there. Can you actually do that? I know it will be inconsistent with the design, but there is nothing in the area that could interfere with this arrangement of the cable. There are no gas pipes, water pipes, other power lines. What do you think about it?

What will happen in a few years? Will you remember the exact route of the cable? And will the cable be located only on your plot?

The cable route lying on your site may be changed as a minor deviation, but the part extending beyond your plot must coincide with the design.
The route of the laid and buried cable and not only the cable can always be checked, there are suitable devices for this.

Not only devices but also people, e.g. a surveyor who will measure its route as built.

Filling 50 cm of soil is a significant change in water conditions, in the event of a complaint from a neighbor or construction supervision inspection, you may have to restore the plot to its original condition.

The area is designed so that I can easily cover these 50 cm. At this point, the foundation protrudes above the ground level by approx. 60-70 cm. In the project, I have an area designed in such a way that I have to fertilize the earth. Therefore, I would like to run the electric cable first, so that I do not have to dig an 80 cm groove, but now dig 30 cm and cover it with soil.
The cable is only on my plot. The pole with the box is also on the border of my plot. The distance between the pole and the house is 15 m. The architect has routed the cable in the project in such a way that it will come out 30 m. The cable goes left and right. Instead of running in a straight line from the pole to the house, the cable goes practically in a zigzag. You can imagine it for yourself if I have to give 30 m of cable over a distance of 15 m ...
Therefore, the electrician came up with the idea to run the cable in a straight line without these bends. There is nothing else in this place, it does not pass through other plots of land. So I understand that this is an irrelevant deviation and can be changed.

And how did the surveyor check the compliance of the cable with the design? Did he just draw what the architect had marked, or did he check it with some measuring devices?

He probably went overboard with twice the length, but there should always be a spare cable (post 7).
I remember the building site where the cable went straight, but at one point it was laid in an "S".

Show the map, we will discuss it. The idiot draws zigzags for no reason.

Stock at the ZPK. The cable is laid in a wave. The coefficient of 1.04 for the cost estimate.
So stop, gentlemen, pie .... stupid things.

You haven't seen it, so don't accuse me of writing nonsense it is possible that it was foolish to do so (in S).
I saw, I was surprised and asked why they put it that way.
It was not a single-family house but a building of one of the universities in Łódź.
Connection power (if I remember correctly) approx. 180 kW. Power supply from own 15 kV / 240 V substation to the new building.
The location of the "esa" is marked on the plan.

It wasn't up to you. I wrote generally about the discussion and the unknown reasons for this and not another project. That's why I wrote:

Or maybe the author meant "zigzagging", that is, deliberately laying the cable in the ground with a hose?

And then machines will start to drive on the terrain, and it is not known what will happen to this cable. In my opinion, bury at 60cm. After pouring the soil, it will be 110 cm, which will better protect the cable from accidental damage in the future.

This is a reserve in case the cable is damaged or, for example, the pole is moved by the power industry. Stop thinking in terms of Polish trash looking for savings where there are none. Ask yourself what will be cheaper, e.g. in the case of moving the pole: digging up a piece of spare or stripping the cable (additional cable section + muff)?

Your friend probably deigns to joke, as much as 100% of the stock?
The reserve is left at the pole, ZK, at most a few meters, not along the entire route.
How will they replace the pole or rebuild the lines in 10 years, no one will tear a beautifully kept garden on the plot in search of a cable that allegedly has a "supply" spread all over the area Anyway, which contractor or subcontractor winning the tender is included in the work?
They will put on an ordinary muff and that's it.

In the past, the cables on the maps were drawn in a zigzag pattern, which did not mean that it should be arranged this way, because you just can't get a thick cable.

I suspect that the architect zigzagged the area where the electric cable can be laid. However, the implementation is based on the precise drawing of the route
cable and the location of the cable reserve taking into account the execution of a possible future connector - some slight excess.
everything related to the implementation of this cable connection.
It just showed just the area where the cable could end up. Nobody sensible
will not build a zigzag power cable line with a view to
saving own land and other possibilities of its use.

I propose to refrain from speculating until the Author has complied with Jack's request in post # 10.

Tomorrow I will post a scan because at the moment I do not have a map with me. But I still have a question for you about the cable itself. Does the electric cable from the pole to the house have to be additionally arranged in a conduit, e.g. arot, or can you forgive yourself?

Has to? Who told you that? He can't to be in any peszlach or arota. It can't!

Even when the ground is clayey and wet? I understand that it can't because water can stand in it or is there any other reason?

I wonder how many more posts will be written on such a simple matter as curves laying the cable.
The cable is laid in the ground in a sand cover. Pipes only at the intersection with other utilities. Practically, the cable can be laid along its entire length in the pipe in one case. The cable is laid when the flowers are blooming, cubes and marbles are arranged and the green grass grows. That is, in the case when the land development was ahead of the time of laying the cable. In this case, the Investor should arrange the cable anyway before arranging the plot.

I think you need to order a design from an electrical designer. The architect draws some lines - outlines of general thoughts. The detailed execution will be determined by an electrician designer.
Using the opinions of the forum is not a form suitable for receiving the work performed - for the future commissioning committee. So there is also no form of a document taking into account any as-built or material deviations, etc. The forum will not create a document either ... And it is paved with good intentions ....

You're wrong. The architect collaborates with industry professionals when designing the project. If the investor does not need "art" to obtain a building permit, the architect has to hand over a complete design compliant with applicable regulations. I adhere to one rule, if I do something for PLN 1 + VAT, my project is complete from the point of view of the purpose it is to serve.
By observing the market, I can see that my approach is outdated. The youth of today do many wonderful stupid things without looking at their consequences.

So the industry professionals - architects - for a joke - gave the route of the electric cable going
"Gzygzakiem" "Immortal work."

I will not agree with my colleague, unless my colleague writes in the jargon of this topic.

Deviating from the topic:
Currently, I see LV / MV cables laid in pipes more and more often. The cost-effective installation of cables in pipes is similar to sand, but depending on the terrain, the cable itself, the number of people needed, and the number of joints is much smaller. We dig a ditch, lay pipes, backfill - we do not play with land occupation (temporarily related to fees), we do not play archaeological excavations that make it difficult to move the equipment, we do not play hundreds of meters of white and red tape waving in the trees. We do not play with cable damage in case of unknowing damage by heavy equipment.

In addition, cable laying has another important advantage - it is almost impossible to drag cables if the cable on the drum is undamaged (unless the sewer has large angles and many bends but it is dishwashing liquid and excavation for the control channel). In the event of cable damage, e.g. due to heavy equipment (I had a topic recently), you will dig up the damaged place - I had to replace the entire section due to the requirements of the lack of using couplings. There was no problem.

Defects:
- echo during listening while taking measurements of a damaged cable,
- difficulties with 'burning' the cable without specialized equipment.

The basic use of protective pipes are terrain conditions, especially stony ground / shifting soil, where the removal of the native soil, fertilization of sand / soil without stones is more expensive than the pipes themselves. Other cases besides securing the cables are the convenience of the contractor.

If it is about the existing state and the inability to dig in an unarmed area, it is only a jacking / drilling.



Coming back to the topic, the basis is the land development design and the location of the pole / building and the faulty cable. Like my colleagues, I am waiting for the PZT.

Exactly not. Compensation of land subsidence, as a large layer is still to be fertilized.

Has to? Who told you that? He can't be in any hoes or chicks. It can't!

Why? Additional cover against mechanical damage.
