DU Diederichs has been successful in the area of project management for more than 30 years. Our customers have a measurable benefit from our experience, in the form of optimised costs, met deadlines and the quality achieved. We will service and support you throughout all stages of construction, from the first project considerations through to the commissioning date.
DU Diederichs follows a comprehensive project management concept. As part of our offer, we take on project management, project control, and render expert certificates to support you in the case of litigation.
In the scope of project development, we create portfolio analyses and take on real estate management. We always aim at optimal value creation, to prepare the basis for a beneficial facility management.

Project management

It gives us great pleasure that the term 'project management in the construction industry' has become widely familiar, requiring hardly any explanation. It is inseparably connected to the basic work of our company founder, Professor Diederichs. Project management, project supervision and project control are our core business, continuously being developed.

Project control

We set the standard, you set the goals for your project. With our support, both scope for decision making and traceability in the 'transparent project' are developed.

Project supervision

You have the self-confidence and the trust to delegate decision-making authority? Then you can expect perfect work, information and achievement of your project goals.

Expert certificates

With or without external project management, the parties involved in a project are not always at one with each other. Good advise can help to avoid long discussions.


Trust is good, control is better. DU Diederichs enjoys the confidence of many building owners, and is a preferred controller for internal or external project management.

General planning

Building owners attach more and more importance to planning services from one single source – with quality standards especially developed for a project and synchronised with a client's demands by DU Diederichs.
