Rehabilitation and Retrofit

Structural rehabilitation and retrofit services address deterioration, seismic risk, and evolving code requirements for buildings that are occupied, operational, or historically significant. RDH develops retrofit strategies that balance engineering requirements with constructability, phasing, and stakeholder goals, covering everything from targeted strengthening to full structural upgrades.

• Retrofit strategy development establishes a clear path for structural upgrades, including access planning, construction phasing, and integration with enclosure work.
• Structural strengthening design provides detailed designs for columns, beams, diaphragms, and connections requiring upgrade or load redistribution.
• Code compliance evaluation identifies required interventions based on local codes, intended use, and permit review requirements.
• Historic structural rehabilitation develops solutions that preserve character-defining elements while upgrading strength, resilience, and performance.
