The weather is inviolable.

Then share it according to the objective situation. It is really impossible to construct due to objective reasons, such as the construction conditions are completely unavailable, or the probability of production safety accidents caused by forced construction is very high. The delay caused by this situation cannot be blamed on the construction party.

However, if the construction is inconvenient, the cost will increase, because the contract has clearly stipulated that the defense of force majeure caused by bad weather will be overcome by the construction party itself. If you can't finish the work, you will be liable for breach of contract.

As for the extent to which the weather affects it, it is up to both parties to provide evidence and the judge to judge.
