Turnkey plant engineering and construction – the realisation of complex turnkey projects.

Our complete approach that distinguishes us in all our projects especially benefits us in the turnkey area.

Particularly, in the business field of turnkey plant engineering and construction, we can optimally play the card of the extensive range of business activities in the Marmara Group: integrated engineering, and installation and erection competencies from a single source, controlled through central project management. We consider an early involvement with the installation and erection teams in the engineering process to be an essential requirement in order to establish efficient construction processes, avoid re-engineering and be able to realise a maintenance friendly industrial plant.

Whether a new plant, revamp or a package unit – we steer your complete project efficiently and with minimised interfaces up to full take over of the technical and commercial project responsibility. Experienced project managers ensure goal-oriented coordination of all planning, construction and commissioning services. They are thereby supported by qualified project controllers, schedulers and project assistants. Hence, we create the best possible basis for on-time, in-budget execution of turnkey projects in various contract forms.
