Founded in Honolulu by Frank Xiong, AIA, and Justin Matoi, SE, XM Consultants (XMC) integrates architecture and structural engineering with a focus on supporting existing buildings. We specialize in building diagnostics and repair design, solving the complex structural and material challenges posed by Hawaii’s unique environment.

Our practice is rooted in technical expertise across materials, building systems, engineering principles, and the rigorous application of building codes. This specialized foundation allows us to deliver coordinated solutions to a wide range of projects and clients. 

We understand the distinct performance challenges created by Hawaii’s diverse climate, coastal exposures, and aging building stock, and we are committed to extending the lifespan and resilience of our local built environment.
