Design That Elevates Performance

Our vertical transportation design services ensure people and performance move efficiently through every space. We provide complete elevator system design, from the programming phase, modeling, and capacity analysis to modernization and new construction integration. Our team conducts detailed site surveys, evaluates existing equipment, and performs code reviews to ensure safety and compliance. Using advanced computerized traffic modeling software, we analyze and optimize every system for reliability, efficiency, and seamless building integration.

Our Offerings
Programming Phase Modeling

We provide high-fidelity vertical transportation modeling at the earliest stages of design to define the core of your building’s performance. By applying advanced simulation algorithms to preliminary architectural concepts, we ensure your facility’s “spinal column” is perfectly sized for dynamic occupancy patterns.


Our programming phase deliverables provide the data-driven confidence needed to freeze the building core, ensuring that vertical mobility scales seamlessly with your facility’s future growth.


Site Surveys

Trivium provides comprehensive forensic evaluations of existing vertical transportation assets to identify hidden risks and define clear paths for modernization. Our site surveys deliver a prioritized roadmap of recommendations, allowing facility managers to transition from reactive repairs to a proactive, data-driven maintenance strategy.


Existing Equipment Evaluation

At Trivium, we provide rigorous technical audits of vertical transportation assets to determine their true operational health, safety compliance, and remaining service life. Moving beyond standard maintenance checklists, our evaluation process uses precision diagnostics to help Owners decide whether to repair, retain, or replace critical elevator components.


Code Review and Analysis

We provide technical oversight to ensure your vertical transportation systems meet the stringent safety and regulatory requirements. As codes evolve to incorporate new technologies, our analysis ensures your project remains compliant, safe, and fully permitted.


Modernization of Existing Elevators

We specialize in the strategic revitalization of aging vertical transportation systems, extending the lifecycle of your assets while dramatically improving performance and safety. Trivium’s modernization approach replaces obsolete technology with “future-ready” components, ensuring your elevators meet the demands of modern occupancy and 2026 energy standards.


New Construction Design

We provide comprehensive engineering for new vertical transportation systems, serving as a critical bridge between architectural vision and mechanical reality. By integrating the most advanced hoistway technologies during the initial design phase, we ensure your building’s core is optimized for peak performance, maximum leasable square footage, and long-term sustainability.


From high-rise traction systems to specialized service and freight logistics, we design vertical transportation that is as resilient as it is intuitive.


Computerized Traffic Modeling Software and Analysis

Trivium will utilize industry-leading simulation software to virtually stress-test a building’s vertical transportation system before a single rail is installed. By creating a digital twin of your facility’s expected occupancy, we provide the empirical data required to optimize passenger flow, reduce wait times, and maximize the efficiency of the building’s core.
