ᐅ Conduits on the Property – Any Ideas? – It’s Not Too Late Yet :)

Hello house building enthusiasts,
My civil engineer is starting the groundwork now (gravel slab for the house and garage). Since he is making the gravel slab up to the property boundary, I’m concerned it might be tight for running electrical cable to the front and back gardens. Additionally, I’m planning an irrigation system, and the water hoses will need to be routed accordingly.
Would it make sense to have the civil engineer install conduits directly, so I can later lay underground electrical cables and PE water pipes without having to dig again? I’m thinking especially about areas without topsoil cover, like the garage and driveway.
Do you have any other tips on what I could implement at this stage?
The house is built without a basement, and the garage has strip foundations without a slab.
Thank you all.

@opalau They have more individual parts, like three threaded fittings.
I'm still not sure where exactly that is supposed to be.
There are four sprinklers over a 2-meter (6.6-foot) diameter... That is exactly in the center of the lawn area, Zone 2 (green), with one supply line, three MP3000 sprinklers, and one MP2000.
Where are these couplings located? Do you mean the T-pieces with a 3/4-inch thread on the long side?

Fittings cannot be placed directly one after the other (except if they have threads).
Therefore, there must always be a short length of pipe between them.
How are you connecting the sprinkler bodies? Do you have the complete connection kits? There are several options.
If you have the kits with T-pieces, do it as planned. Use an end cap at the end. Not ordered yet, but in my case the kits don’t seem practical since the T-pieces are counterproductive, right? Wouldn’t it be better to use a 90-degree fitting on 1/2 inch (1.27 cm) pipe, then attach the flexible hose, and then the MP (micro-sprinkler) body? Or does that not affect the water pressure? I also still need an end cap.

I have both. T-joints and 90-degree elbows for 1/2 inch (13mm) pipe. For example, if I have a line with 3 sprinklers, two branch off with T-joints, and the last one at the end uses a 90-degree elbow. Shouldn't angles be avoided? Why not run straight to the last sprinkler instead of using a 90-degree elbow?
A straight line isn’t really possible here. The sprinkler is positioned vertically to the PE pipe, which itself is only about 20-50 cm (8-20 inches) underground. So bending the pipe won’t work. I use BluLock hoses for the last meter (3 feet) leading to the sprinkler. With those, you can create a smoother bend – that’s true.
I hadn’t considered that. But it doesn’t make a big difference now. Maybe none at all regarding pressure loss. I noted somewhere that a 90-degree bend causes about 0.01 bar pressure loss. If I don’t use a 90-degree fitting but instead a wide curve with BluLock, I avoid the sharp angle but have more (centimeters-)meters of the thin 1/2” hose. That also causes pressure loss.
Since the pressure loss ultimately only affects this last sprinkler, these 0.01 bar should easily be covered as a margin in the system. No one designs their system that close to the limit anyway.

It can’t really be straight. The sprinkler is perpendicular to the PE pipe, and the PE pipe is only buried about 20-50 cm (8-20 inches) underground. So bending it isn’t an option. I have BluLock hoses for the last meter (yard) to the sprinkler. Those could of course make the curve smoother – that’s true.

Since the pressure loss only affects the last sprinkler, those 0.01 bar should easily be available as a buffer in the system. Nobody would design their system that close to the limit anyways. True, probably not relevant in practice. I’m just starting my own planning, so these considerations are always interesting.
