Seismic & Existing Buildings

What it is

Existing-building work starts with understanding the structure that is already there. Melqart evaluates existing systems, identifies structural constraints, and develops strengthening or modification strategies that respond to seismic demands, new loads, and changing building use.

When you need it

When an existing building needs seismic evaluation, strengthening, a major alteration, added loads, a change in use, or structural upgrades to support a renovation or reuse strategy.

What we provide

Core seismic & existing buildings capabilities.

Seismic evaluation

Review of existing gravity and lateral systems to understand seismic vulnerabilities and project-specific strengthening needs.

Retrofit and strengthening

Design of targeted structural upgrades including new frames, walls, collectors, anchors, connections, and local reinforcement.

Alterations and additions

Engineering for new openings, added floor or roof area, equipment loads, tenant improvements, and changes to existing load paths.

Adaptive reuse

Structural coordination when an existing building is repurposed, modernized, or modified for a new program.

FAQ

When does an existing building need structural evaluation?

Evaluation is commonly needed when a building is being altered, expanded, retrofitted, damaged, repurposed, or reviewed for seismic performance.

Can Melqart design seismic strengthening?

Yes. Client project materials show seismic retrofit and strengthening work on existing commercial and residential structures.

Can retrofit work be coordinated around an occupied building?

Project-specific phasing and constructability can be considered where work must be coordinated with existing operations or constrained sites.
