Mechanical Engineering

In the marketplace of ideas, diversity and depth are the currency.

Our designs are diverse and range from moisture control for aquatic facilities throughout the West, to the region’s only Level-1 trauma center. Clients trust our knowledge of building environmental systems. We work closely with our clients to achieve sustainable, efficient, and maintainable designs that match the functional needs of each client and project. Our mechanical engineers have designed diversified HVAC systems including heat recovery systems (waste heat utilization) and controlled climate systems. We are knowledgeable in the areas of analyzing and selecting heating, ventilation, and air conditioning systems for unique and complex facilities. We are well versed in plumbing and piping design allowing clients to rest easy in knowing we are looking out for their best interests.

Our mechanical engineering consultants support our services with computer simulations for life-cycle cost analysis. We also perform mechanical system assessments for large facilities, pipe replacement and retrofit design for older structures, and master planning of mechanical systems for healthcare and campus-style projects.

Services include:

  • HVAC and plumbing for commercial, high-technology, institutional, and government sectors
  • Central plants for cooling, heating, electricity generation, compressed air, medical gases, etc.
  • Automatic temperature control systems
  • Bulk fuel storage systems
  • Life-Cycle Cost Analysis (LCCA)
  • High-pressure/high-temperature process piping
  • High density heat gain facilities, i.e. data centers (up to 300 watts/square foot)
  • Pipe stress computer analyses
  • Material handling design
  • Machine design
  • Laboratory design (animal, bio-safety, bio-hazard, and research facilities)
  • Building system computer simulations for performance and energy analysis
  • Building systems commissioning
  • Industrial ventilation
  • Forensic work
  • Fire protection
