Why choose BuildEXT building engineering design?
Building services engineering is at the heart of a building’s operation. Flawless mechanical engineering designs ensure comfort, energy efficiency, and safety. BuildEXT’s mechanical engineering design team provides all this in a BIM-based, integrated process, so that designs are not only accurate but also support the entire life cycle of the building.
For our clients, this means that our designs can be implemented quickly, are fully coordinated with other disciplines, and result in fewer errors and delays during construction. For our engineers, it means that mechanical engineering design is not a background task: it represents independent value, and in an integrated BIM environment, they have an even greater professional impact on the success of projects.
How are we different?
- Integrated BIM – real-time collision detection, accurate modeling, quick decision support
- Custom systems – complex mechanical engineering solutions for industrial, laboratory, and large facilities.
- AI and automation – our proprietary tools speed up work and improve quality.
- A strong professional community – mechanical engineers, architects, structural engineers, and electrical designers working together as a truly integrated team.
We organize information into systems
How do we work?
Our work always begins with a thorough understanding of requirements and functions. We prepare conceptual designs based on BIM, and then use integrated detailed designs to avoid conflicts that may arise during construction, right from the design phase.
Thanks to our developments and AI-based automation, our work is faster and more reliable, and support throughout implementation and operation ensures that our designs retain their value in the long term.
Mechanical design and modeling
➔ Solutions and workflow
Our role in BIM-based mechanical design is to ensure that the mechanical content of the models is properly worked out down to the last detail. This includes the various system calculations, bill of quantities, P&ID-s as well as the clash coordinated models. Beyond the design phase, we support construction and project management with CDE.


➔ Data Management
We use our template systems to create all design data in a structured order, from the type to the last instance. Using a combination of Revit’s built-in parameters and additional shared parameters allows us to create full models and designs at every stage of the closed BIM process, from concept to as-built models. This also includes models optimized for facility maintenance.
Our system is also flexible in terms of data management to meet clients’ requirements in adding extra details, model-based calculations, and preparation for simulation facility management uses.
➔ Calculations & Model based design scope
We can validate our designs and models according to international regulations and standards such as ISO, Ashrae, EN, FM, LEED. Our calculation methods are integrated into our Revit-based BIM ecosystem.
Whether it’s an office building, laboratory or custom industrial building, our building services engineering design is always integrated and fast.
Projects
h17 condominium
Consideration and assimilation of existing building values in a vision
GIRO office building modernization
Cutting-edge hybrid office addressing post-COVID organizational challenges
Academia
Interior redesign of the representative Danube-side office building of the Academia. The project involved the design of 1800 m2 of community, commercial and office space.
Other services
We offer solutions through the total lifecycle in order to make projects effective and sustainable from all economical, human, and ecological perspectives.
General design
We have been designing large-scale and complex industrial, commercial, office and public buildings for more than 15 years. We work for a sustainable future with an innovative approach.
Interior design
We design the ideal environments of the future. Our goal is to appeal more to human instinct, the human condition, and human sensibilities.
BIM services
Having a sustainable approach we take care of the building throughout its entire lifecycle. By exploiting the possibilities of the BIM working method, we provide a comprehensive service from design through construction to operation.
Project management
By pushing all the advantages of the BIM workflow we represent the interest of our client, reduce expenses and ensure quality work from our consultants.
BIM FM services
We integrate operations and maintenance on a BIM model to make them more efficient, cheaper and better managed
