PHASE I - The Seismic Risk Survey

ABS Consulting engineers survey, evaluate, and inventory critical structures and/or equipment systems. The scope of work entails review of available structural drawings, soil reports, seismological data, and performing site visits. Structural/seismic deficiencies are discussed and general recommendations provided to mitigate the seismic risk. This Phase I seismic risk audit also provides information regarding projected facility damage and downtime and business interruption costs following a major earthquake.

PHASE II - Seismic Risk Identification and Evaluation

Detailed specific seismic risks associated with selected facilities and equipment systems are identified. The scope of work consists of systematic and detailed analyses of the capabilities of structures and equipment, and includes development of preliminary strengthening concepts, and cost/benefit assessments for retrofit design and construction.

At this stage ABS Consulting may propose several different retrofit schemes, based upon different levels of required facility performance. These may vary from life-safety for cost-conscious clients, to minimizing business interruption for high-value production or essential service facilities. We may also recommend non-structural solutions such as enhanced emergency preparedness and response planning, occupancy changes, transferring the risk through insurance, or other strategies.

PHASE III - Selection and Implementation of the Risk Reduction Program

The preferred strategy for risk reduction is finalized. This may entail finishing conceptual strengthening designs and project criteria initiated during Phase II, and developing complete construction documents (drawings and specifications) to implement seismic retrofit measures. Typically this phase includes close coordination of work with other disciplines (such as architectural, mechanical, and electrical) required to implement the recommended facility upgrade measures. In other instances, this phase may involve preparation or enhancement of a disaster preparedness and recovery plan and training a client’s staff in implementing the plan; or it may involve other aspects of facility planning such as development of risk-averse design criteria for new construction.
