Since 2012, Rivera Engineering & Associates has been providing comprehensive structural engineering services throughout the Carolinas. With nearly 20 years of combined experience, we specialize in residential, commercial, and industrial projects.
Our expertise spans structural design, inspections, retrofits, and compliance with Charlotte's unique soil conditions and building codes. We've built our reputation on delivering safe, efficient, and cost-effective structural solutions.
After two decades of using industry-standard FEA tools, we recognized a critical gap in the market: powerful structural analysis software that's both affordable and intuitive.
REA Structures is our answer—a next-generation finite element analysis tool built by structural engineers, for structural engineers.
Advanced multi-threaded solver delivers results 3-5x faster than traditional FEA software
Clean, modern UI designed for structural engineers—not aerospace physicists
Linear & nonlinear analysis, dynamic response, buckling, and seismic evaluation
Real-time 3D rendering with intuitive stress visualization and deformation displays
Direct CAD import (AutoCAD, Revit, SketchUp) and export to industry-standard formats
Built-in design checks for AISC, ACI, IBC, ASCE 7, and international codes
Run analyses locally or leverage cloud computing for massive models
Transparent subscription model—no hidden fees, no enterprise lock-in
Solving the problems that matter most to structural engineers
Enterprise-grade analysis at a fraction of the cost. No more choosing between powerful software and your budget.
Optimize designs in real-time. Run parametric studies in minutes, not hours. Meet tight deadlines with confidence.
