How Can We Help You?

We work collaboratively with our clients to provide them excellence in process 
design, safety analysis, project engineering and management, and other 
technical and professional services.

What are P&IDs?

Process flow diagrams (PFDs) and process and instrument drawings (P&IDs) are widely utilized in chemical and process engineering industries.  These diagrams show the flow of chemicals and the equipment involved in the process.  More generic in nature, a PFD typically shows only the major equipment and the general process flow.  Often, PFDs are used for visitor information and new employee training.

P&IDs are typically more detailed than a PFD, including major and minor flows, control loops, and instrumentation.  P&IDs are frequently used by process technicians and instrument and electrical, mechanical, safety, and engineering personnel.  Ultimately, a P&ID is a graphic representation of a process system that includes the piping, vessels, control valves, instrumentation, and other process components and equipment in the system.


Why are P&IDs Important?

Since P&IDs provide a representation of the interconnection of process equipment and the instrumentation used to control the process, they are essential in the maintenance and modification of process equipment and instrumentation.  Further, accurate P&IDs allow personnel to review the process from both the technical functionality and safety perspectives.  Without up to date diagrams of as-built processes, proper analysis, maintenance, and modification cannot be performed effectively or efficiently. 

What is 3D Modeling?

3D modeling is the creation of a three-dimensional object inside of simulated software.  The object can be created from simple shapes all the way up to complex, high-polygon models.  Often - and depending on the format of modeling you're trying to achieve - real-world objects are scanned into the software through a 3D-scanning device; then, those objects are used as digital tracing paper to create the final model.  Once created, these objects can be scaled and manipulated however the user sees fit.


Why is 3D Modeling Important?

Have a process that's being installed in a tight space?  Unsure of the footprint of a proposed new project?  Need to design special equipment for fabrication?​  You need a 3D model!

3D modeling is utilized throughout the engineering and architecture industries in a number of ways.  For example, 3D CAD modeling can be used to create interactive renderings of buildings, structures, and processes for real-life construction.  Additionally, 3D modeling allows the creation of to-scale designs for equipment or part fabrication.

How Can We Help?


​Resources, resources, resources!  Plant and facility personnel wear many hats, leaving little time for tasks such as P&ID updates.  Often, these drawings are not updated after process installation or as process changes occur throughout the life of the process.  Beyond maintenance and process modification, having accurate P&IDs is critical during an incident investigation or Hazard Analysis to help ensure the process is correctly evaluated for risks and associated causes.  


As site contractors, we provide: 

  • P&ID Verifications​

    • Evaluation of P&ID accuracy by field verification​

    • Instrumentation and control system updates​

    • Incorporation of equipment / piping / process details​

    • Drafting services​

  • Plant & Facility Layouts

Our team of experienced chemical engineers and process technicians perform process walkdowns to provide "As-Built" redlines which are then drafted in AutoCAD.  All produced deliverables are compliant with International Society of Automation (ISA) Standard S5.1.  Accurate P&IDs can also be of great benefit to plant maintenance personnel when troubleshooting or planning preventive maintenance or turnaround work.

If you have any questions or would like any additional information on our P&ID services, please do not hesitate to Contact Us.

3D Modeling

Whether you're looking for equipment design or interactive process layout development, we can help!  IE Group offers personnel with experience using industry-accepted modeling software such as SolidWorks and several Autodesk and Intergraph products.  We work with our clients to develop 3D models that meet their project needs by performing on-site visits to collect site information and/or scans and producing comprehensive design packages.

If you have any questions or would like any additional information on our 3D Modeling services, please do not hesitate to Contact Us.
