1.  Set-up Enclosure & Get Ventilation System Running
2.  Perform a Primary Sand Blast
3.  Surveys:      a.  Locate Damaged Concrete – Sound with hammer & mark out boundaries           of bad concrete      b.  Locate Near Surface Metal – Use metal detectors and visual inspection to locate           and mark surface metals to be removed      c.  Locate Shallow Rebar – Use rebar covermeter to locate and mark shallow rebar to           be excavated and covered
