Indoor Environmental Services (IES) engineers develop practical solutions to project requirements. When our engineering team is involved from project conception, the design will be practical, cost effective, project timetable-responsive and constructed with the highest quality work and materials.

IES engineers develop the most practical solutions to your project's requirements. In conjunction with design assistants, estimators, project managers and field personnel, IES engineers review project concepts; ensuring field construction issues are carefully considered in every design.

IES brings significant design expertise in the following types of facilities:

Engineering and Design:

  • Wineries
  • Biotechnology
  • Electronics
  • Pharmaceuticals
  • Food / Beverage Processing
  • Medical Clinics
  • Health Care Facilities
  • Office Buildings
  • Schools
  • Educational Institutions
  • Hotels

Our engineering capability is intrinsic to our success. IES employs registered professional engineers, LEED (Leadership in Energy & Environmental Design) certified engineers, Certified Energy Managers and CAD professionals who are able to provide engineering services at any stage of the construction, service or maintenance process. As an engineering team, they are responsible for all engineering-design issues company-wide and communicating relevant technical information in areas such as codes, regulation, product advancements, technologies and applications to staff and customers.

Our in-house engineering department is a critical asset to our design-build process. We work with our clients from the first conception of their project to completion. We are staffed with experienced licensed mechanical engineers, designers and CAD operators. Our engineering team has the ability to design comprehensive mechanical systems specific to our clients needs always considering a project's sustainability, cost and timing. Anticipating challenges and finding solutions to potential problems is a strength we have always possessed and will continue to apply on all of our projects. Our solutions-based outlook is one of the main reasons we have developed respect and strong working relationships with the most prestigious design / build construction teams in Northern California.

Mechanical Service Contractors of America, MSCA, has recognized IES as a MSCA STAR Qualified Contractor. We were certified as a MSAC STAR after surpassing stringent business and HVAC service standards set by MSCA. The association initiative of excellence offers proof to building owners and facilities managers that the STAR qualified contractor is providing the highest level of skill, quality, value, training and professionalism in the industry. IES is your certified mechanical industry professional. We are also proud members of ASHRAE (American Society of Heating Refrigerating and Air Conditioning Engineers), Association of Energy Engineers, Association of Plumbing Engineers, Co-Generation & Competitive Institute of AEE.
