Material inspection ensures that the highest quality materials are being used on-site. Laboratory tests are the usual method to check the discharge capacity, tensile strength, AOS, and permeability of the drains.

The FISCC-program is a numerical model based on a piecewise-linear finite difference model. The CBFISCC is a numerical solution of the partial non-linear differential equation governing the phenomena.

A trial program can be applied in a project to establish the details of construction control parameters. According to Chang et al. (2010), the design procedures include:

Monitoring dissipation of excess pore pressure is a way to monitoring the progress of consolidation and thus settlement.
