Medical Unit Renovation Audie L. Murphy Memorial VA Hospital

Overview

Prime Architects studied feasible engineering controls to prevent Legionella growth in the hospital’s potable water systems. The facility is about 1 million SF. The study followed VHA Directive 1061.

Technical Scope

  • Assessment/Pre-design: Evaluated water temperature limits for Legionella control in the hot and cold water distribution systems. Reviewed the June 2014 Audie L. Murphy Potable Water System Chlorination Study.
  • Plumbing: Recommended continuous water temperature monitoring at multiple points in the hot and cold water systems. Analyzed best options for hot and cold water temperatures.
  • Operations and maintenance: Delivered a regular flushing O&M plan, organized by location.
  • Cost analysis: Delivered a cost analysis for continuous monitoring equipment and installation.

Outcome

Deliverables included prioritized options for meeting hot and cold water Legionella requirements, a monitoring cost analysis and a flushing plan.
