Case Study

Fabricated steel silos: ongoing engineering support across design, review and live queries

Initially brought in for 3D CAD expertise, Frugal went on to provide broader ongoing mechanical engineering design services across drawing production, design review, manufacturability input, structural assessment, and live technical queries.

Situation

The client needed ongoing engineering design consultancy support across a live flow of design, detailing, review, and technical problem-solving work. What began as targeted 3D CAD work gradually widened into a broader role covering drawing production, design review, manufacturability input, structural assessment, and day-to-day technical queries.

The real problem

The tasks changed from week to week, but the underlying need was consistent: dependable senior engineering input that already understood the client’s products, manufacturing context and current priorities.

The client needed support that could move between technical queries, design reviews and updates, drawings, calculations and bounded delivery tasks while retaining context across them, rather than treating every issue as a separate commission.

Constraints

  • Different levels of response: Work ranged from answering quick technical questions to producing 3D models, drawings, sketches and mark-ups, calculations, FEA and technical notes.

  • Changing priorities: The mix of review, delivery and problem-solving changed as projects evolved.

  • Effective use of retained capacity: Available time needed to be directed towards the decisions and deliverables that would add most value at each point.

Highlights

Improved the quality and usability of engineering output

  • Simplified and rebuilt CAD so models were more practical to use, review, and build from
  • Produced clearer engineering drawing information and more dependable release material for manufacture

Applied senior judgement to live project decisions

  • Contributed to design reviews, technical queries and manufacturability decisions as work evolved
  • Resolved issues with the benefit of retained product and project context, rather than approaching each as a disconnected task

Maintained continuity across changing priorities

  • Moved between review, delivery and problem-solving work as priorities changed, while retaining context across the client’s products and projects
  • Gave the client access to experienced engineering input without requiring equivalent permanent in-house capacity

Separated larger tasks into defined packages

  • When larger, well-bounded tasks emerged, they were scoped and delivered separately from the ongoing retainer
  • This kept the retainer focused on responsive, judgement-led work while giving larger delivery tasks clearer scope, programme and control

Outcome

Over time, CAD became more usable, drawing information became clearer and more dependable for manufacture, and live technical issues were resolved with greater continuity and context.

The client also gained a practical route for handling work of different sizes, from technical decisions and smaller bounded tasks through to separately scoped delivery packages.

What this enabled

The arrangement gave the client ongoing access to senior engineering judgement without maintaining equivalent full-time capacity in-house.

Because context was retained across tasks, new issues could be picked up quickly, while larger packages could move into a more structured delivery route when required.

Ongoing client relationship

Over three and a half years, the client retained Frugal across mechanical design, review, structural assessment, drawings and live technical support. More than £270k of work was commissioned over that period.
