Engineering and design, delivered on the agreed date
Keep design off
your critical path.
Send us the design or the decision, and the date. You get the package on that date, carried through every change since.
Fixed fee. Agreed date. Named engineering review.
For plant owners & equipment manufacturers
Every project waits on
design somewhere.
The gate is booked and the package is not ready. Your engineers are running the plant, the consultancy has its own lead time, and the last accepted drawing is in someone’s inbox. So the project buffers for design: float, early orders, contingency in every price.
We prepare the package the decision needs and carry each change through the drawings, lists and quantities together. Your engineers decide instead of redraw.
- A customer orders a variantAdapt an existing design · a modification, tie-in or variant from the design you already have.
- You are about to build itFind issues before site · fire, weather, strength and fit checks, with the scenarios agreed per assignment.
- The same design keeps coming backMake your designs reusable · your components and house rules as a versioned library your engineer accepts.

A taller tank.
Everything that follows.
Raise the shell from 12 to 15 metres. The design model adds two courses and moves the roof, then reruns what depends on the height: course 2 thickens, the shell needs a wind girder, the stair gains a landing, and the overflow nozzle is left 3.2 m below the liquid level, so the issue is flagged before anyone redraws.

One change,
start to finish.
Four steps, an agreed date and a fixed fee. The same for a variant, an audit or a pre-study.
Receive. Bring what you have.
Your drawings or model, the change, the deadline and who on your side accepts the result. We agree the scope, the checks, the fee and the date before work starts.
Prepare. AI prepares the revision.
The change is carried through the geometry, quantities and drawings together, and permitted engineering tools check it against the criteria we agreed.
Review. A named engineer decides.
What needs judgement comes back with the reasoning. Open items and assumptions are listed, not hidden. You decide what follows.
Record. You keep the package.
Drawings, model, quantities, findings and the sign-off with its limitations, kept with its source so the next change starts from what was accepted.
- No hourly billing: the fee is agreed on the result.
- Changes within the brief are included, without moving the date.
- The agreed checks always run, even when the date is close.
- Our mistakes are our cost, never extra work on your invoice.
Quality, made visible
Know what
was checked.
The checks are agreed before work starts and the evidence arrives with the design, so your team sees what was assessed and what was not.
