10Years of disciplinary expertise
We turn complex engineering problems into innovative, advanced solutions that add value to your projects.
ProYA Engineering is an engineering firm dedicated to uniting structural safety with an innovative engineering vision. With our team specialized in earthquake and civil engineering disciplines, we provide end-to-end advanced engineering services, from conventional structural design to energy-dissipating systems, steel structure design, and site supervision.
We carry out our design processes in full compliance with world-class nonlinear time-history analysis (NLTHA) procedures and current codes, securing structural performance through international engineering standards. Our priority is to deliver safe, effective, and economical solutions.

02 — Approach3 principles · ProYA methodology
We approach every project through the shared framework of three principles.
Science-based decisions
Beyond codes, guided by science. We shape our decisions not only by minimum standards, but by international advanced engineering criteria using linear and nonlinear time-history analyses. We safeguard your project’s structural safety with scientific data.
Economic feasibility
Safe engineering, optimized cost. Using advanced analysis methods, we produce the most rational solutions without compromising structural safety. We handle structural design not through templates, but with a holistic approach that optimizes materials, labor, and construction processes.
Transparent reporting
Clarity at every step, confidence in every report. We make every stage of our design process traceable. By clearly reporting all boundary conditions and criteria used in structural analyses, we produce fully understandable, reviewable, and defensible outputs for all project stakeholders.
