System Optimization

System optimization is the “activity of enhancing system capabilities and integration of subsystem elements to the extent that all components operate at or above user expectations”.  R&A applies a Systems Approach to Engineering to achieve system optimization by listening to our clients, developing thoughtful solutions, and efficiently and effectively executing the final product.

Commissioning is a process of design and construction quality assurance that verifies a project is meeting the owner’s established goals. R&A has a certified Commissioning Authority on staff, and has either led or supported many commissioning efforts through the years ranging from capital improvement projects to ground-up hospitals.

Master Planning

Master planning identifies the necessary components to implement renovations, expansions or enhancements to mechanical and plumbing systems to provide greater efficiencies, integration, functionality, and longevity.  Having a meaningful understanding of a building or campus infrastructure requirements and limitations can help save money and improve overall sustainability.
