What we design
We are designers and engineers. We design, calculate, permit and supervise; your contractor builds, with a design that works.

Sheet 04 · Layered model
A warehouse is six projects that have to fit together.
Pick the type of space, rotate the model and switch each layer. This is how we work in BIM: every discipline in one coordinated model before work starts on site.

Not a conventional engineering firm. We start with your process.
First we understand how you work, then we design where.

How many loading docks does your warehouse need?
The costliest mistake is sizing with the daily average. Docks are sized for the peak hour.
Arrivals and departures that coincide in the busiest hour.
Homogeneous palletised load ≈ 20 min. Manual mixed unloading, over an hour.
If there are seasonal peaks, docks must absorb them.

Preliminary estimate with a 20% safety margin. Final sizing is validated in the project with the real fleet and flow simulation.

Extension of the medical centre in Sant Joan Despí: more space, more functionality
When a medical centre needs to grow, it is not just a matter of adding square metres. The extension has to integrate well into the whole and respond to an activity in which comfort, accessibility and functionality are key. That is what the ALTERTECNIA team has done in the extension of a private medical centre in Sant Joan Despí (Barcelona).

Why loading dock design shapes all day-to-day logistics
How many minutes are lost per day, per week, per month… because a vehicle is waiting its turn to load or unload? In industrial logistics, efficiency is not created in the warehouse alone: it is forged much earlier, in the design of the loading docks and in how smoothly vehicles and workers share the same space.

How we designed an industrial cold room: more capacity without compromising operations
In an industrial facility with refrigeration, the capacity of the cold room is a key factor in the success of the project. In this project for Panabad, one of the key elements was precisely that: designing a large cold room capable of meeting storage and order-preparation needs. And to achieve this, decisions had to be taken from the very start of the project.
