The two houses are very close, but the foundations are very different. The excavation of foundation pit has a great influence on your home. Related cases can be seen in the building collapse in Jing 'an District of Shanghai in 20 1 year. It is suggested that before the excavation of the other party's foundation pit, you can ask the other party to find a foundation pit monitoring institution to monitor the excavation, and at the same time, you can find a good house appraisal institution to appraise your house. After the other basement is backfilled, you can compare the results once and twice. At the same time, make a good record of photos and videos during this period, so as to make claims later.
