Structural Design
CYS provides structural engineering design for diverse building types including airports, hospitals, educational facilities, and industrial structures. Our solutions integrate advanced technology and safety standards for both private and public sector clients. With expertise in complex projects, we deliver customized designs that meet functional and regulatory requirements while ensuring long-term durability.
Historic Restoration
Our engineers specialize in restoring historic buildings while maintaining their architectural integrity. We implement cost-effective seismic upgrades and conservation techniques that preserve cultural significance. By balancing modern safety standards with historical accuracy, we ensure these structures remain functional and protected for future generations through sensitive, code-compliant interventions.
Seismic Analysis
CYS conducts comprehensive seismic evaluations using FEMA and ASCE guidelines to identify structural vulnerabilities. Our team develops retrofit solutions for buildings, bridges, and state infrastructure, incorporating innovative techniques like base isolation and energy dissipation systems. With decades of experience in seismic safety programs, we help clients achieve compliance and enhance resilience against earthquake risks.
Project Management
We provide end-to-end project management for complex building projects using reliable control systems. Our approach ensures timely delivery within budget constraints, as demonstrated by successful $161 million prison facility completion with minimal change orders. By integrating design and management expertise, we streamline processes and maintain quality throughout the project lifecycle.
Seismic Evaluation
CYS performs detailed seismic risk assessments for California state buildings, hospitals, and commercial properties. Our evaluations follow SB1950/SB499 protocols and ASCE/SEI 31 standards to determine structural deficiencies.
