Every major isolator manufacturer makes proprietary bearings that have unique attributes, properties and capacities. For most applications, the isolation system and manufacturer are selected after an evaluation of product suitability and technical merit, total construction cost, bearing price, and technical support services.
 
All projects benefit by selecting the seismic isolation system and supplier early in the design process. Early selection reduces costs and improves reliability by having a qualified isolation system supplier as part of the design team. The alternative of bidding the isolation bearings at construction time has resulted in the worst seismic performance based on the lowest common bearing properties, and the highest total construction cost.
 
EPS has made early supplier selection easy for our customers. We offer the best seismic performance, highest strength bearings, highest engineering qualifications, most comprehensive testing, and the lowest total construction cost, all supported by competitive bearing prices.
 
EPS's most valued contribution to our customers has been in the design and implementation of the complete isolation solution. Our engineering qualifications and implementation experience in the field of seismic isolation far exceed those of any other company.
 
We have a long list of very satisfied government and private clients that selected EPS early in the design process. Private clients typically use an informal evaluation by the engineer, considering seismic performance, safety, and total construction cost. The State of California Department of Transportation, Caltrans, selects the bearings and supplier early in the design, using a simple selection process based on bearing capacities, properties, and price, provided by qualified suppliers.
 
In 1991, the U.S. Court of Appeals project was awarded to EPS early in the project design using a formal U.S. Federal Government competitive source selection process. The supplier selection was based on product seismic performance, total construction costs, quoted unit bearing prices, design costs, and manufacturer's design support. For over 16 years, EPS has consistently out-performed competitive suppliers on major projects based on these selection criteria. Read a summary of this selection process
