Mechanical Engineering & Drafting Services


Your Mechanical Engineering & Drafting Experts

SMI’s Mechanical Engineering & Drafting Department has over 80 years of experience designing and creating detailed plans for permitting and construction, along with “As Builds” and P&IDs. SMI also assists clients with documentation needed for older mechanical systems, as plans disappear and modifications are done without proper documentation. This difficult issue is faced in many existing facilities. SMI has the tools, know-how, and qualified staff to create and deliver those documents.


Our mechanical drafting designs provide a complete picture of the mechanical piping and associated control systems which include the following:

  • Mechanical Site Plans

  • Pipe Routing

  • Equipment Specification Data Blocks

  • P&ID’s

  • Low-Level Signal Control Devices

  • Mechanical Equipment Layout

  • Process Flow Line Diagrams

  • Valve Schedules

  • Interlocking Control Devices

  • Thermocouple & RTD Locations
