Special Inspections

Special inspections are inspections and tests of building components critical to the building’s structural integrity. Special inspections can help identify defects and deficient work resulting in fewer problems and a dramatic improvement in the quality of construction.

The special inspection process is in addition to those inspections conducted by the municipal building inspector and the engineer or architect. SCI’s special inspection group works closely with clients to inspect and test the materials used in construction to minimize risks and liabilities.

Our special inspection group is overseen by a certified Master of Special Inspection and our inspectors are certified by the International Code Council, American Welding Society, and American Concrete Institute.

Special inspections include, but are not limited to:

  • Structural steel welding and bolting
  • Structural masonry
  • Reinforced concrete
  • Post-tensioned, concrete
  • Roof anchor testing
