Services
Mechanical Design
Our mechanical engineering team designs high-efficiency HVAC systems for commercial and industrial applications. We specialize in variable refrigerant flow systems, dedicated outdoor air systems, and central plant optimization. With 20+ years of combined experience, our engineers deliver solutions that balance energy efficiency with operational reliability for new construction and retrofit projects.
Electrical Design
We provide comprehensive electrical system design including power distribution, lighting solutions, and life safety systems. Our expertise covers building utility services, emergency power generation, and advanced lighting controls. Through detailed photometric analysis and code compliance checks, we ensure electrical systems meet both functional requirements and sustainability goals for diverse facility types.
Sustainable Design
Our sustainable design approach integrates energy-efficient systems and environmentally responsible technologies. We implement LEED-certified strategies, ground source heat pumps, and energy recovery systems while maintaining compliance with Washington State's strict energy codes. This holistic methodology reduces environmental impact while optimizing long-term operational costs for clients.
Building Information Modeling
We utilize advanced BIM technologies for 3D system visualization and coordination. Our team creates detailed digital twins for HVAC, plumbing, and electrical systems to identify conflicts before construction. This technology enables accurate clash detection, virtual walkthroughs, and improved project coordination between design and construction teams.
Fire Protection Design
Our fire protection engineering covers comprehensive sprinkler system design, standpipe configurations, and fire pump specifications. We design both wet and dry systems tailored to facility requirements while ensuring compliance with local codes. Our integrated approach coordinates fire protection with overall building systems for optimal safety and functionality.
