ISO 19650 audited services in
accordance with international standards
Engineering Detailed Design – MEP
Years of expertise in using different CDE environments in complex and large-scale BIM projects enable us to efficiently integrate our solutions to the client’s needs in regards to language, documentation standards, information content, and geometry detail level.
Our ISO 19650 audited BIM services are available for large-scale and complex industrial, commercial, office, and public building projects.
Mechanical Design & Modelling
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. Combined with our CDE workflow, we can always provide the client with a transparent overview of the design development.
Data Management
We use our own template systems to create all design data at its relevant location, from the type to the last instance. Using a combination of Revit Native and additional shared parameters gives us the leverage to provide complete models & designs at every stage of the design, from concept to as-built models, as well as models that are prepared for facility management.
This includes calculated design data, data sheets any other necessary information. Our system is also flexible in terms of data management to meet client requirements. To add extra details, model-based calculations, preparation for simulation facility management uses.
Calculations and Model-based Design Scope
We are able to validate our designs and models according to international regulations and standards such as ISO, ASHRAE, EN, FM, and LEED. Our calculation methods are integrated into our BIM-based ecosystem.


Electrical Design & Modelling
Solutions and Workflow
Based on electrical design, the main data in a project is stored in the closed BIM Revit. Similar to the MEC discipline, we provide complete data about the modeled or designed elements and systems during the project.
We also use a combination of Revit native functionality and advanced electrical design plug-ins. This gives us leverage in load calculations, circuit design, lighting design, and earthing.
Low Voltage
In the case of low voltage design, our scope of design starts from the site/power supply entry point of the building and goes all the way to the very last endpoint.
With a wide portfolio of electrical manufacturers, we can offer different solutions for any type of project in compliance with EN and ISO standards. In terms of detail drawings, we provide all in Revit. P&ID-s main switchboards as well with countable equipment.


Lighting Design
In the scope of lighting design, the two main factors are calculation and geometry. In our own BIM approach, we create lighting designs to fulfill electrical and interior design requirements as well.
Earthing & Lightning Protection
Within the scope of Earthing & Lighting Protection, these kinds of discipline-related elements are hardly countable in quantity form in the industry.
BuildEXT has developed a workflow to support the design calculation with actual earthing and lighting simulations. We have also developed a Revit family template system to make all the equipment related to grounding systems properly displayed and countable in 3D.
Fire Protection Design & Modelling
Solutions and Workflow
Fire safety is perhaps the least addressed area of BIM and is also approached differently in various countries. To meet the needs of our customers, we have divided fire protection into 3 sub-disciplines.
Each BIM-based fire protection discipline entity has its own templates and Revit families. During a project design collaboration, each of them is taken into account to create complex fire protection. This goes from the concept phase to the end of the design.
Architecture Fire Protection
Architecture-based designs such as wall fire protection ratings, fire compartment data, and fire hydrant hose length plans are placed in the Revit Architecture model.
The associated hazard classifications and fire alarm zoning are also placed in the architectural model.
Depending on the project requirements, this method can prove its worth to both the third-party design team and the client. All fire protection information is available in the related building model without having to open the other related discipline containing the detailed design.
Built-in extinguishing systems
Built-in fire protection systems such as sprinklers are designed in a separate model.
Calculation modules are linked to the models. From detail design, P&IDs to zoning is presented in a BIM environment.
Our solutions include sprinkler wet, and dry systems as well in VdS, FM, NFPA as well as local legislation requirements.
Fire Alarm & Detection
As it is mainly fire and electrical protection related, Fire Alarm & Detection also has a separate model during a project design to maintain data integrity.
With its own warehouse, template and prepared parameters, from BS to EN standards we are able to provide solutions.


Working in a common data environment (CDE) significantly increases the level of collaboration between the engineers involved. The architect, structural engineer, mechanical engineer, electrical engineer, and other engineers work simultaneously on the same common model, sharing relevant details with project stakeholders at any time. This makes decision-making easier, problems can be solved quickly and the quality of the final product will be outstanding.
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.
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.
Scan to BIM
We use the latest 3D laser scanner technology to survey buildings and sites. We process this information and provide services to reduce costs for our customers.
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.
