This type of evaluation in general focuses on the nature of the problems related with construction distress. Also, the causal mechanisms of the damage that has occurred post construction due to other factors.
The primary mechanism for this type of movement observed on a distressed site mainly manifests as variations in floor level and open parallel cracks to the edge of the depression zone or a descending slope . The distress usually manifests by hairline to large open cracks. The cracks can be distinct with vertical displacement.
Where the distress is manifested on concrete slab areas then the crack and hairline associated with the distress become usually uneven with vertical displacement. The distress elements are associated in general with soil settlement or expansion along the bearing walls, or concentrated loads.
Distress elements can accelerate by earth movement such as creep phenomenon on hillside areas. A frequent factor in primary cause of the distress in most cases is water seepage below the foundation and/or lack of proper drainage maintenance after construction.
