Excavate the foundation trench in accordance with design specifications and test the bearing capacity of the foundation soil.
Implement foundation treatment measures-such as replacement filling, reinforcement, and compaction-to ensure compliance with the required bearing capacity.
Level any uneven or sloped rock surfaces using concrete.
If the foundation cannot be seated directly on bedrock, it must be embedded at a depth of at least 1.5 meters below the scour line; scour-protection mats shall be laid along the outer perimeter of the foundation.
