Turnkey Process Systems Design & Fabrication Services

EPIC provides complete project management services for turnkey process systems design projects. You bring the process technology and we’ll handle every step from concept development through final startup of your process equipment. Your EPIC project manager will provide you with a simple but effective project management experience.

Each of our clients is paired with an EPIC engineer who has experience relevant to their particular industry. This project manager will communicate your needs to the rest of your project team, which includes in-house process and automation engineers, module designers, skilled craftsmen and quality assurance professionals. By streamlining the project management experience, our clients benefit from fewer change orders, faster startup times and a more cohesive process system overall.

You bring the process technology, and EPIC process engineers do the rest. Scaling systems to production size or adapting your technology to a manufacturing environment is our expertise and industrial engineering consulting services. The first stage of any project is the concept stage, provided by the client. You might start with a drawing or basic spec sheet. Whatever stage you’re at, we can help you develop PFD’s or fill-in the intermediate processing steps before moving into the design engineering services stage and developing full Process and Instrumentation Diagrams (P&ID’s).

Unlike other engineering consulting firms, we guarantee the most accurate bid you will receive by fully extracting your requirements, including process equipment cost estimation, ultimately resulting in advanced process solutions. The key to this WIN-WIN outcome is: Front End Engineering (FEE). Learn more about our non-traditional approach…

The design work that started in front-end engineering is finished during the design stage. Using our process system engineering and physical design capabilities, EPIC develops your custom modular process system for your proprietary, base process technology.

Milestones completed during design:

  • Detailed process design
  • Mechanical design
  • Structural design
  • Hardware specification

Process controls work begins concurrently during the design of your system. EPIC focuses on providing the most comprehensive solution for your manufacturing goals. EPIC has over 17 years of experience specifically providing process programming in the areas of:

  • Programming Platforms
    • Logic Programming
    • PLC Programming
    • PC-Based Programming
    • DCS Programming
    • Operator Interface and HMI programming


  • Process data collection
  • Process simulation
  • Process Instrumentation
  • Process Systems Integration
  • Specialty Process Systems

As one of America’s leading design build firms, our on-site fabrication plant and modular approach provides a time-savings advantage complimented by production-quality fabrication. To prepare for on-site installation, our engineers manage the project, prefabrication and plant & equipment skid design/construction in parallel to ensure your site is ready both internally and externally for the new processing system solutions.

  • Advantages of Modular Process Systems Fabrication: Finished process plants are brought to market faster with modular process fabrication. Through parallel construction and offsite fabrication, modular fabrication reduces downtime associated with traditional construction methods.

Our project managers fully integrate and install your new modular process system into your manufacturing facility. This may include processing plant integration, construction management and control system programming.

  • Testing & Shipment: FAT (Factory Acceptance Testing) is completed before shipment. Process systems and process equipment shipped by EPIC are designed for mobility and are insured. They arrive on-site ready for installation and startup.
Batch Reaction Start-Up

Punch list resolution, plus operator and maintenance training will be completed by an EPIC process engineer for your finished skid. Continuing project support is extended to all customers after project completion for troubleshooting any issues.

plant commissioning and startup

We are here to support your systems long after they have passed through our stringent Quality Assurance program and are successfully commissioned at your facility. Our team provides on-going customer support that includes:

  • Technical support, including
    • Automation and programming troubleshooting
    • On-demand issue troubleshooting
    • Remote access problem resolution (if desired)
