WRK provides detailed seismic evaluation of facilities using the ASCE 31-03 Standard document. This document is the recognized national standard for seismic evaluation of existing buildings and utilizes a three-tiered evaluation process.
The Tier One procedure is a preliminary screening tool designed to quickly identify potential seismic deficiencies of a building’s lateral force resisting system as well as the nonstructural building systems. The Tier One evaluation procedure uses a series of checklists for rapid evaluation of the building while requiring only a minimum level of structural calculations.
The Tier Two and Tier Three portions of the ASCE 31 evaluation are analysis-based evaluation procedures used to demonstrate that the Tier One potential seismic deficiencies are, in fact, satisfactory and do not require rehabilitation.
WRK delivers all findings and recommendations in a complete Seismic Evaluation Report.
