Expert Engineering Solutions for You
Building Information Modeling (BIM) is rapidly becoming the industry standard in building design—minimizing errors and improving project delivery well before construction begins. By optimizing the design process and maximizing usable square footage, BIM creates value for all stakeholders.
At Mendoza Engineering we use BIM to streamline complexity and enhance collaboration, making the design process more efficient and effective. The result? Smarter decisions, smoother execution, and better outcomes for everyone involved.
We simplify the complex so you can focus on what matters most—making an impact.






Our Commitment to Excellence
California’s Title 24 Energy Code is a cornerstone of the state’s commitment to energy efficiency and carbon reduction in the built environment. As California continues to lead in sustainability, Title 24 plays a critical role in ensuring that commercial and residential buildings contribute to long-term energy savings and environmental protection.
The 2025 update to Title 24 places a stronger emphasis on electrification, renewable energy integration, and intelligent building controls. These changes are designed to reduce greenhouse gas emissions, lower utility costs, and improve indoor comfort and air quality.
At Mendoza Engineering, we understand that compliance with Title 24 is not just about meeting regulatory requirements—it’s about enhancing building performance, reducing operational costs, and supporting California’s clean energy future. Our team stays current with evolving standards to help clients navigate the complexities of compliance with clarity and confidence.
