IS International is a licensed professional engineering firm and has built our reputation around evaluating and upgrading SCADA and control systems, and assisting clients in implementing new integrated systems solutions. Over 90% of our work for the last 20 years has been turn-key design-build projects requiring full understanding of client needs, processes, and constraints of operation.  We working with our customers to develop specifications for a monitoring and control system optimized to meet or exceed their performance requirements for years.

As part of our professional engineering design services or performing as a traditional systems integrator/contractor, we provide instrumentation and controls detailed design (panel electrical, mechanical, installation details, loop drawings, etc.), systems integration (controls and communications hardware configuration, HMI, PLC, DCS software programming), testing and commissioning services. We have expertise designing and integrating many hardware and software platforms, as well as broad process controls knowledge. Our business relies heavily on automating our engineering execution process utilizing proprietary tools developed by IS.  Our software enhancements for project related work, allow us to deliver top tier engineering at very competitive pricing.

As your engineering partner, IS takes ownership of our responsibilities and projects, and you can depend on a positive project process, experience and outcome.
