Bridging Process and Controls for Smarter Industrial Design

OUR SERVICES

Process Design & System Development

SiS provides process design and system development support for industrial fluid handling, pressure control, and automated process systems. Our goal is to produce clear, accurate, and buildable process documentation that forms the foundation for fabrication and automation integration.

Capabilities include:

  • Process flow diagram (PFD) and piping & instrumentation diagram (P&ID) development (AutoCAD LT)

  • Hydraulic line sizing and pressure drop analysis

  • Equipment and instrumentation specification and selection

  • System layout optimization for constructability and maintainability

  • Process datasheet and design basis document preparation

  • Vendor coordination for instrumentation, valves, and piping components

  • Drawing and deliverable quality review for documentation consistency

SiS ensures every design package is technically sound, well-documented, and aligned with client standards — ready for efficient transition to controls integration and fabrication.

Controls, Automation, & Integration

SiS provides controls and automation design services that translate process intent into functional and maintainable industrial control systems. Our team specializes in Allen-Bradley PLC/HMI programming, control system documentation, and hardware integration that meet NFPA 70 Article 409 and UL 508A standards for Industrial Control Panels.

Capabilities include:

  • Control philosophy, logic narrative, and Cause & Effect matrix development

  • PLC and HMI programming (RSLogix 500, Connected Components Workbench (CCW), Studio 5000, FactoryTalk View ME, EBPro - Maple Systems)

  • Industrial control panel design and component specification per NFPA 70 Article 409 and UL 508A

  • Instrument loop diagram and termination drawing preparation and review

  • I/O allocation and tag database development

  • Factory Acceptance Test (FAT) procedure development and support

  • Integration planning between process, instrumentation, and automation systems

SiS bridges the gap between process design and automation execution, delivering reliable control system solutions that support smooth commissioning and long-term operational stability.

Fabrication & Assembly Services

SiS partners with qualified sub-fabricators to deliver complete, build-ready control and process assemblies — ensuring seamless execution of design intent. All fabrication is performed under SiS technical oversight and adheres to industry codes and applicable standards.

Capabilities include:

  • Fabrication of industrial control panels meeting NFPA 70 Article 409 and UL 508A requirements

  • Design and assembly of instrumented process skids and automated valve manifolds

  • Integration of piping, valves, and instrumentation into modular process systems

  • Fabrication package preparation, including drawings, BOMs, and build documentation

  • Coordination with UL-certified and ASME-qualified fabrication partners

  • Electrical and pneumatic tubing layout for control skids and local panels

  • Quality review, build verification, and readiness documentation prior to FAT

Through this integrated model, SiS provides clients with fully documented, technically validated, and fabrication-ready solutions — combining process design, controls integration, and build execution under one cohesive framework.

About us

Sheridan Industrial Systems, LLC (SiS) is a technical consulting and design firm specializing in process system development, controls integration, and project execution support for industrial applications.

Founded by Alex M. Sheridan, M.S., SiS was established to bridge the gap between process design intent and practical field implementation — delivering efficient, maintainable, and automation-ready systems built on proven design standards.

With over 15 years of experience in process industries, Alex has led multidisciplinary engineering and automation teams on projects ranging from small packaged systems to large-scale facility expansions. His background in process design, instrumentation, and control systems integration brings a hands-on, systems-level approach to every project.

SiS partners with fabricators, integrators, and engineering firms to provide scalable technical support — from concept development and documentation through fabrication coordination, startup, and commissioning. Our work emphasizes clarity, constructability, and compliance with industry codes and best practices, ensuring each deliverable transitions cleanly from drawing to fabrication to operation.

At Sheridan Industrial Systems, we believe effective design is more than documentation — it’s a collaboration between process understanding, control logic, and real-world application.

Core Values

  • Integrity – Upholding technical and professional ethics in every engagement.

  • Precision – Delivering documentation & design intent that are clear, consistent, and buildable.

  • Collaboration – Working seamlessly with fabricators, suppliers, and engineering partners.

  • Accountability – Supporting clients from initial design through project completion.
