ᐅ Should a conduit be installed for telecommunications?

Hello,

On April 29th, the civil engineering company will start installing gas, water, and electricity lines. For three months now, the telecom provider has failed to send the order to the civil engineering company to install their cables at the same time. Originally, the plan was to lay a 75 DN (nominal diameter) KG conduit alongside the other installations. However, we have now realized that a PE pipe is required, which is somewhat more expensive than a KG pipe. We do not want to spend money on an empty conduit just because the telecom provider has not gotten their act together. After all, 100 € is 100 €.

Question: The telecom connection costs 799.00 €. If we decide to skip the empty conduit, will this result in additional costs later since retrofitting will be more effort without an existing conduit? The driveway will only be paved next year anyway, so having to dig it up again would not be a problem for us.

I didn't know that civil engineering work and conduit installation were included! :-( With us, the shell builder (general contractor) has now completed everything, and the company commissioned by the telecom provider only has to pull the fiber optic cable through the 5m (16 feet) long conduit. The cable end is already accessible, and the conduit starts right there. So, we basically paid twice.

I need to bring this topic up again here:

Despite multiple assurances, the telecom company still hasn’t managed to send out the order. Of course, I wasn’t informed about this either, despite their promises. I need to have the conduit on site by Monday, and now I’m under pressure again. Yes, I know, it’s my own fault for relying on repeated promises from the telecom company…

My neighbor simply had a 1 inch (DN 25) HDPE pipe installed as an empty conduit, and the utility provider (not the telecom company) used it without any issues.

The telecom hotline couldn’t tell me what size to use either. Online, they mention DN 75. The hotline said DN 62/67.5/72 depending on how many services you have. But looking at a table of DN sizes, some of these don’t even exist…

I’m now inclined to just install the 1 inch HDPE pipe and take my chances. If the telecom company refuses to cooperate, they can forget it, and I’ll switch to my neighbor’s provider. That worked out fine.

Question, maybe unnecessary or wrong due to my lack of knowledge: How is the sealing done in a multi-service setup if it’s designed for DN 75 but only DN 25 goes in? Isn’t that problematic?

Alternative: We do nothing and let the telecom company dig everything up again. According to Puma, the first 15 meters inclusive, and we only have just under 12 meters.

I’m really undecided right now what the right approach is…

Buy Kabuflex DN 50 with pull wire and just feed it through. Sell the rest of the roll to the next builder on eBay Classifieds.

@pffreestyler How did that project turn out back then?
