Design & Build Solutions
Integrated planning and implementation from a single source for maximum safety in terms of time, costs and quality.

Plan and build. At the same time
One process instead of many interfaces
Many projects are characterized by unclear requirements, numerous interfaces, time pressure and cost uncertainty. When planning and construction sites do not work in sync, there are additions, delays and quality risks.
Heinle meets these challenges with an integrated design-and-build approach. Planning, execution and commissioning are closely interlinked, responsibility is clearly bundled and decisions remain comprehensible.
In this way, we reduce interfaces, avoid frictional losses and create planning security for complex major electrical engineering projects.
Efficiency comes from interlocking
In today's project reality, planning and construction take place at the same time. This is exactly where Heinle comes in. Execution expertise is incorporated into planning early on, decisions are made more quickly and the construction site remains able to act at any time.
Without this close integration, stable budgets and reliable deadlines for complex projects would not be realistically achievable.

Our way of working in detail
Parallel planning and construction
At Heinle, planning and execution are not carried out one after the other, but in parallel. Decisions are made where they are needed. This speeds up projects and ensures deadlines.
Digital methods and BIM
Model-based planning, laser scanning and digital documentation ensure transparency and a reliable basis for decision-making. Misunderstandings are avoided and complexity can be managed.
Coordinated implementation and start-up
Execution, quality assurance and commissioning are seamlessly intertwined. Transfers are structured, checked and documented. This ensures function and operational safety.
Integrated electrical planning
We develop electrical engineering concepts with a view to subsequent implementation. Aspects relevant to implementation are already taken into account during planning and are continuously developed. This reduces additions and increases planning security.
Real-world projects

FOUR Frankfurt
For the FOUR Frankfurt high-rise project, Heinle provided the complete electrical equipment for one of the most complex construction projects in Germany. These include high-availability energy supply, building automation, safety power supply and detailed energy management for various uses.

- Total area around 200,000 square meters
- Construction period around four years
- Completion 2025
- DGNB platinum certification
- Over 1200 sub-distributions

FRA1 West Mainz
Heinle is responsible for the entire electrical implementation of the FRA1 West Mainz data center. These include medium-voltage distribution systems, busbar systems and power units.

- 24,000 m² of floor space including outdoor area
- Construction period 2024 to 2026
- total capacity of 54 MW
- Around 4,000 meters of power rail
- 2 medium-voltage main distributors
- 24 ring switchgears

DC30 Lübbenau
Large-scale data center project with complete model-based planning of all electrical engineering systems. BIM was used consistently through planning and execution and served as a central control base for a highly complex project environment.

- Output around 200 MW
- Construction period 2025 to 2028
- Over 100 substations
Quality as a measurable factor
Design & Build at Heinle is based on clear internal standards, digital quality assurance and structured testing processes. BIM is standard across all planning phases and is supplemented by defined commission processes.
In this way, we ensure that technical quality, adherence to deadlines and costs are achieved measurably and reproducibly.
