Collapse of geogrid-reinforced retaining structure

Article Abstract:

The collapse of geogrid-reinforced retaining structures is attributed to the reduction in shear strength of the compacted clay backfill due to increased moisture content. This process of moisture migration in clay has been termed as slope softening and has been identified as the main cause of slope deformation. Constant-stress direct shear testing is an effective means to determine the amount of slope deformation due to slope softening and has been suggested for evaluating the failure of geogrid-reinforced retaining structures.

Claims analysis from risk-retention professional liability group

Article Abstract:

Engineers and architects are prone to professional liability claims concerning design errors and omissions in condominium construction projects. These errors are attributed to a compromise between project cost and structural performance. Professional liability risks can be minimized through an independent peer review of structures and by including a mediation-arbitration clause in contracts.
