Engineering for plants that cannot stop

The drawings no longer match the building, the shutdown window is two weeks, and production restarts on a fixed date. This is the work we came from.

01Plant upgrades
02FEED studies
03CAPEX studies

Brownfield projects are constrained by things a greenfield engineer never has to think about: the crane that cannot be taken out of service, the foundation nobody has a drawing for, the clearance that turns out to be 80 mm rather than 300. Getting these wrong is expensive during the shutdown and impossible afterwards.

We start by establishing what is actually there, with laser scanning where the as-builts are unreliable, then design to the real geometry. The schedule is built backwards from the restart date, and interfaces are closed on paper before anyone books a crane.

// What this covers

Inside the scope

01

Plant upgrades

Capacity increases, equipment replacement, layout rework and retrofits designed around a live production calendar.

02

FEED studies

Scope definition and technical baseline for a modification, so the tender goes out with no grey zones in the supply boundary.

03

CAPEX studies

Cost estimation grounded in a real technical basis rather than a percentage uplift on a comparable project.

Where we have done it

Sidenor Basauri (Spain, 2025): workshop refurbishment study covering structural analysis, safety and a new layout for production flow and regulatory compliance. Nervacero (Spain, 2025) and Megasa Maia (Portugal, 2026): canopy structural design and rectification studies for long-products plants, with CFD validation of ventilation and fume control. Aurubis Berango (Spain, 2025): basic and detail design of storage silos plus a tin processing feasibility study. ArcelorMittal Olaberria (Spain, 2026): strategic review of the fume extraction system.
