The second option is a fully automated monitoring scheme where we will attend site and establish monitoring technology that can continuously measure fixed points 24/7. The system consists of a base plate and a reference rod (riser pipe) equipped with necessary threaded end connec- Archives. The most common settlement monitoring system is the settlement plate. For this settlement monitoring a third party independent check is required to ensure that the construction load is not making any settlement beyond the tolerance. Monitoring Survey Service. Monitoring and records → General Monitoring the performance of a road on peat, and the peat below it, provides some very useful information on the stability of the road in the short and medium term. An initial set of baseline measurements are taken from a remote benchmark location not subject to movement from adjacent construction, and repeated periodically to document movement. Structural Health Monitoring Systems (SHMS) are fully integrated and include strain monitoring, load monitoring (active and passive) with GPS systems and automated surveying techniques.

Settlement monitoring instrumentation is typically accomplished using settlement plates which are placed on the ground surface prior to fill placement, extended to the fill surface during ongoing fill placement activities, and surveyed on a regular basis during the monitoring program. Ground monitoring points should be in alignment above the proposed construction activities. Generally conducted by the use of survey Total Station and Target Prism. Permanent settlement measurements can be carried out more efficiently during construction without needing to change survey points.
