WHY STRUCTURAL ENGINEERING?

  • To understand the structural performance under past movement and vulnerability to damage in future seismic events.
  • To ensure the appropriate extent of the house is properly supported.
  • Final spacing of the piers will ensure the foundation will adequately span “like a bridge” to the new piers.
