Overview
Walter P Moore provided integrated structural, civil, traffic, and parking services for the TMC3 Collaborative Research Building, the first facility developed within the Texas Medical Center’s Helix Park campus. The five‑story building integrates research labs, offices, retail, and public collaboration space around a central atrium. A defining challenge was delivering long‑span, vibration‑controlled research floors while coordinating site infrastructure, parking, and access to support phased campus development with unknown future timelines.
Services
Challenges
Long‑Span Research Floors
The research program required column‑free floor bays significantly larger than typical laboratory buildings, increasing demands on structural efficiency and vibration control.
Vibration Sensitivity
Open labs, circulation areas, stairs, and sensitive research equipment required tailored vibration performance across different zones of the building.
Irregular Atrium Geometry
A multi‑story atrium with exposed connector stairs introduced non‑uniform framing conditions, cantilevers, and architectural constraints on member depth and connections.
Campus Phasing
The project needed to accommodate future buildings, underground connections, and access points without limiting long‑term campus development or requiring major rework.
Solutions
Hybrid Structural System
A blended system of reinforced and post‑tensioned concrete with targeted structural steel framing balanced long spans, durability, vibration performance, and constructability.
Optimized Floor Framing
Concrete slabs, pan‑cast beams, and post‑tensioned girders were proportioned to support large bays while reducing overall structural depth relative to a steel‑only solution.
Targeted Vibration Design
Floor bays were designed with varying vibration criteria, enabling sensitive equipment placement in stiffer interior zones while preserving open and flexible layouts elsewhere.
Future‑Ready Site and Parking Planning
Below‑grade parking and site infrastructure were planned to support future campus access, development, and circulation, coordinated with street‑level and landscape elements.
Results
Flexible Research Environment
The structure supports adaptable laboratory and office layouts that can respond to evolving research needs across multiple institutions.
Reliable Occupant Performance
Tailored vibration controls ensure occupant comfort and reliable operation of vibration‑sensitive research equipment throughout the building.
Efficient Building Systems
Reduced structural depth improved coordination with mechanical systems while delivering durable, low‑maintenance floor construction.
Campus‑Scale Adaptability
Integrated site and parking strategies allow phased Helix Park development while preserving walkability, circulation, and long‑term infrastructure flexibility.
