ENGINEERING WITH PURPOSE
From concept to calculation, from drawing to delivery.
Welcome to ARETEC!
ARETEC is a design and engineering consultancy specialising in technical drawing, firestop design, BIM modelling, and advanced simulation. We support the construction, industrial, and manufacturing sectors with tailored, performance-driven solutions, from façade detailing and passive fire protection to FEA, CFD, and fabrication-ready documentation. Based in Spain and the UK, our specialists work closely with architects, engineers, and contractors to turn complex ideas into clear, buildable outcomes. Precision, compliance, and real-world focus are at the core of everything we do.
Our Services
At ARETEC, we provide a comprehensive range of design and engineering services combining technical accuracy and practical insight. Our work supports the construction, industrial, and manufacturing sectors, offering tailored solutions across every stage of the design and production process.

Technical Drawing & Detailing
We produce high-quality 2D drawings for both construction and industry. Every line is drawn with intent, clarity, and precision.
Firestop Design & Documentation
We help ensure passive fire protection is designed and documented effectively.


3D Modelling & BIM
We create accurate, production-ready models tailored to each project’s technical needs and construction stage.
Engineering & Simulation
We specialise in advanced engineering analysis, helping our clients verify, optimise, and future-proof their designs.

What you can expect from us
At ARETEC, we offer a comprehensive range of technical services in engineering design, 2D and 3D drafting, and construction detailing. Our work spans multiple sectors, from industrial manufacturing and mechanical engineering to architectural façades and fire protection systems.
We support our clients throughout every stage of a project. Whether running FEA simulations, producing BIM-ready 3D models, or creating precise fabrication drawings, we always aim to provide clear, reliable, and technically robust solutions that add value and anticipate real-world constraints.
One of our key strengths is merging deep technical knowledge with a refined design sensibility. Our team understands sound engineering is about calculations, clarity, buildability, and long-term performance. That’s why we draw carefully, think ahead, and work fast—without sacrificing rigour.
ARETEC has contributed to various projects, including façade packages, firestop coordination, production drawings for CNC and machining, and fluid and stress analysis. We are flexible and detail-driven, and adapt our workflow to each client’s specific needs, whether you’re building, designing, or manufacturing.
With operations in Spain and the UK, and a growing international reach, ARETEC is a design and engineering partner for those who build with purpose.
