In not a construction worker or have much of a clue how it works but I was wondering about rainy areas and constructions.
I assume that some party of the construction have to be done on a dry environment or to let thinga dry before continuing to other parts.
Some areas have a lot of rain (e.g the British island) so how does it work? Does having a rain for a week is a problem to build a house?

You use big tarps to keep the water away from the construction site. There are of course practical limitations to what can be put under tarps but those are rarely critical things. You also have large heaters that can be used to keep things warm and dry under the tarp. Most things which can not handle water will still be able to handle some water as long as it can dry out afterwards so transporting and storage may still be done in the rain.
So typically when the construction start you set up some containers for supplies, offices, break room, etc. and stretch a tarp between them for outdoor storage. The heavy machines that dig out the foundations can work in the rain. Workers get equipped with rain gear and weather proof equipment. You might need pumps to keep the water out of the pit but usually not as you want the foundations to have drainage in the end anyway. Once the foundations are dug you pore the concrete in the rain. And then you may cover the foundations with a large tarp and use heaters to get the conditions right for curing concrete.
When building the house you generally rush to get the roof done, or at least the beams in place so you can tarp it. Wood can safely get rained on but not for many weeks so you want to get the roof and sides done as soon as possible and keep it under tarps. You do also get scaffolds that can be built in the shape of the house so the tarps can be put on this scaffolding.
