         1.1   Collapse of footing or foundation system;
         1.2   Damage to footing, foundation, concrete or other structural element due to soil expansion;
         1.3   Adverse effects to the design strength of footing, foundation, concrete or other structural element due to a chemical reaction from the soil;
         1.4   Inadequate soil as determined by a geotechnical investigation;
         1.5   Where the allowable bearing capacity of the soil is in doubt; or
         1.6   Adverse effects to the footing, foundation, concrete or other structural element due to the ground water table.
      2.   Concrete that has been subjected to any of the following conditions:
         2.1   Deterioration;
         2.2   Ultimate deformation;
         2.3   Fractures;
         2.4   Fissures;
         2.5   Spalling;
         2.6   Exposed reinforcement; or
         2.7   Detached, dislodged or failing connections.
      3.   Aluminum that has been subjected to any of the following conditions:
         3.1   Deterioration;
         3.2   Corrosion;
         3.3   Elastic deformation;
         3.4   Ultimate deformation;
         3.5   Stress or strain cracks;
         3.6   Joint fatigue; or
         3.7   Detached, dislodged or failing connections.
      4.   Masonry that has been subjected to any of the following conditions:
         4.1   Deterioration;
         4.2   Ultimate deformation;
         4.3   Fractures in masonry or mortar joints;
         4.4   Fissures in masonry or mortar joints;
         4.5   Spalling;
         4.6   Exposed reinforcement; or
         4.7   Detached, dislodged or failing connections.
      5.   Steel that has been subjected to any of the following conditions:
         5.1   Deterioration;
         5.2   Elastic deformation;
         5.3   Ultimate deformation;
         5.4   Metal fatigue; or
         5.5   Detached, dislodged or failing connections.
      6.   Wood that has been subjected to any of the following conditions:
         6.1   Ultimate deformation;
         6.2   Deterioration;
         6.3   Damage from insects, rodents and other vermin;
         6.4   Fire damage beyond charring;
         6.5   Significant splits and checks;
         6.6   Horizontal shear cracks;
         6.7   Vertical shear cracks;
         6.8   Inadequate support;
         6.9   Detached, dislodged or failing connections; or
         6.10   Excessive cutting and notching.
   Exceptions:
