Feasibility Studies

At STB Engineering we have over 40 years experience in designing, manufacturing and installing bulk handling and pneumatic conveying systems, particularly in the food and plastics industries.

During this time, we have worked with many clients who have known what they want from a new system installation but haven’t been sure of the best layout and design.

This is where our experience is key. We understand that every job is different and will require specific solutions to ensure optimum production. We can share our experience by carrying out a full, independent
feasibility study on your project, which will result in an in depth
report which is yours to keep.

We will quote for the work as part of the report. If you choose to use our services the first thing we do is produce an integrated project timetable, liaising with all parties including the customer, suppliers and subcontractors.

We then manage the timetable to
ensure agreed deadlines and
specifications are met.

Included in the feasibility study:*


  • Site visits as required (initial visit free of charge)
  • Site survey
  • Collection of data
  • Comparison of original installation equipment capacity & transfer rates with the proposed design upgrades or plant improvements
  • Use of our in-house test facility
  • Conveying calculations
  • Production of design concepts, schematics and layout drawings
  • Process specifications
  • Functional design specification (F.D.S)
  • Quotation for works
  • Report findings and make relevant recommendations for improvements
