HIGH COST OF FAILURE

摘要

Geosynthetics used in waste containment facilities have occasionally encountered problems due to substandard geosynthetics, construction methodology, inadequate or inappropriate design, and poor operating practices.These problems are normally detected during construction or operational stages and the associated costs to correct them are many times higher than the original construction amount. This situation sometimes results in impacts to public health, loss of reputation and litigation. Fundamentally, through proper design, well planned material quality assurance (MQA) and construction quality assurance (CQA) most of the problems can be eliminated and consequently reduce or practically avoid the possibilities of damage to the natural environment and public health and safety. Vital collaborative participation of the key players in the industry: designer, MQA/CQA, and independent testing laboratories are important to a successful outcome. These coupled with administration and implementation of governmental statutes affecting the activities in all phases of waste containment projects will ensure attainment of the previously cited goals.
