project execution with so called "GÜ" and "GMP" Contract Models – Efficient Construction Planning & Cost Certainty
With our expertise in project execution and the tailored choice of suitable contract models, we support you in the secure, timely, and cost-efficient implementation of your construction project – from the first draft to completion.

Our PLANNING division offers you a structured and transparent project execution using General Contractor (GÜ) and Guaranteed Maximum Price (GMP) contract models. We handle the entire coordination, optimize construction workflows, and ensure maximum cost control and schedule adherence. Through precise planning, close management, and cooperative collaboration with all parties, we minimize risks and ensure an efficient, economical, and quality-assured execution of your project.
General Contractor Model (GÜ) – Everything from One Source
In the General Contractor (GÜ) model, a single partner is responsible for the execution planning and the entire construction implementation. This means all trades are centrally coordinated, simplifying communication and increasing efficiency.

- Centralized Responsibility: One contact for all project phases reduces interface issues and simplifies communication.
- Efficient Coordination: Bundling trades allows for optimal resource use and shortened construction time.
- Cost Transparency: Clear contractual agreements ensure a transparent cost structure and reduce the risk of add-ons.
This model is particularly suitable for projects that require close integration of planning and execution to ensure high quality and adherence to deadlines. Our PLANNING division takes over complete control and coordination of your construction project within a General Contractor (GÜ) model.
We act as your single point of contact, manage all trades, and ensure a smoothly coordinated project execution. Through efficient planning and close collaboration with proven partners, we minimize interface issues, reduce planning errors, and ensure your project is delivered on time and within budget.
Guaranteed Maximum Price Model (GMP) – Maximum Cost Security
The Guaranteed Maximum Price (GMP) model sets a guaranteed upper price for the project. If actual costs fall below this price, both client and contractor share the savings. If exceeded, the contractor bears the additional costs, creating a strong incentive for efficiency.

- Cost Security: The fixed maximum price protects the client from unforeseen cost increases.
- Incentive System: Shared savings motivate both parties to work cost-efficiently.
- Transparency: Open calculations foster trust and cooperation between contracting parties.
We strategically use the GMP model to provide you with maximum cost transparency and planning security. With our precise calculations, cost control, and budgeting experience, we guarantee a fixed upper price, preventing unexpected overruns.
Through close cost monitoring and targeted resource optimization, we ensure an economically efficient construction project. At the same time, you benefit from our open communication, which strengthens trust among all stakeholders and enables a collaborative working environment.
Integrated project execution (IPA) – Partnering for Success
In addition to GÜ and GMP models, Integrated project execution (IPA) is gaining importance. Here, all key participants – clients, planners, and contractors – work together early on and across organizational boundaries as a team.

- Early Collaboration: Joint planning helps identify and minimize risks early on.
- Optimized Processes: Synergies among participants lead to more efficient processes and higher quality.
- Shared Responsibility: A shared understanding of project goals promotes collaboration and reduces conflict potential.
Our PLANNING division stands for Integrated project execution (IPA), where we form a strong team with clients, specialists, and contractors from the beginning. Through early collaboration, we optimize processes, identify and resolve potential conflicts in the planning phase, and enhance the efficiency of your construction project.
Our structured planning and control processes ensure top quality, precise scheduling, and a well-thought-out, economical implementation.
