Engage a qualified professional to inspect the components every 2 years. 3) Conduct a retest of mitigated areas at least every 2 years and retest all previously tested locations of the building up to the third floor level at least every 5 years. In addition, retest when any of the following occur: ü A new addition is constructed or alterations for building reconfiguration or rehabilitation occur; ü A ground-contact area not previously tested is occupied; ü Heating or cooling systems are altered with changes to air distribution or pressure relationships; ü Ventilation is altered by extensive weatherization, changes to mechanical systems or comparable procedures; ü Sizable openings to soil occur due to: — ground water or slab surface water control systems are added or altered (e.g., sumps, perimeter drain tile, shower/tub retrofits, etc.); or — natural settlement causing major cracks to develop; ü Earthquakes, construction blasting or formation of sink holes nearby; or ü A mitigation system is altered, modified or repaired. 4) Disclose the existence of themitigation systemand its purpose for protecting health and safety to current and future occupants or tenants.
