Excavate the area: This process involves heavy machinery that digs down the soil beneath the foundation to create additional space in ADU. This process is carried out carefully right after the designing phase and involves careful excavation so that the surroundings would not get affected. This way, you can save a lot of trouble and only good engineers can help you.
Shore up the foundation: To prevent the foundation from collapsing during the excavation process, temporary supports such as steel beams or hydraulic jacks are used to hold up the foundation while soil is removed. Add new space: With the foundation shored up, new space can be added to the ADU. This may involve adding new walls, floors, or other structural elements to create a new level or basement.
Strengthen the foundation: Once the new space has been added, the foundation can be strengthened by adding new concrete footings or steel reinforcement.
Backfill and finish: Once the foundation has been strengthened, the excavated area can be backfilled with soil and finished to match the surrounding area.
