Core Service: Seismic Retrofit Evaluation / Monitoring

Seismic Evaluation

GBG works with architects, engineers and building owners to perform assessments of building construction, oftentimes identifying reinforcement arrangement in concrete structures ahead of seismic upgrade or for verification of code compliance.

These surveys are carried out using a combination of ground penetrating radar (GPR), metal detection and cover meters to determine extent, spacing depth of cover and diameter of reinforcement.

In other cases, GBG can identify variations in construction that may affect seismic performance such as changes in thickness or material type, defects such as cracks and voiding as well as locating formed voids such as utility chases and flues.
