Public Seismic Strengthening

When it comes to safety, we go the extra mile.

We addressed the challenge of a Risk Level V building with strategic seismic strengthening, ensuring the safety of all occupants.

The Problem:

ASCE 31 evaluation revealed a Risk Level V for the building, necessitating action.

The Solution:

StrongHold™ - designed in accordance with ASCE 41 and ACI 440.2R for seismic strengthening.

Installation timing kept the building operational during business hours to prevent any loss of use while HJ3 projects were installed for the repair!
