Concept development

We can help you define which project delivery methodology is best for your particular project and help you manage the full process concept development. Considering what parts can be modularised is part of this stage.

Feasibility studies

Is your planned project profitable? Is your technological solution feasible? We can help you find out by investigating opportunities, challenges, risks and costs. We can define the most feasible technological solution for you and prepare all relevant documentation you need when seeking financing for your plant.

FEED/Basic engineering

Citec offers FEED/Basic services for your plant to ensure constructability. P&ID, equipment & plant component requirements defined by all disciplines.

Extended basic engineering

During the extended basic engineering stage, foundation loads are defined and 30% plant model is approved by customer. This stage is executed by a Citec team geographically close to you. When completed, work may be downloaded to BCC (best cost country). The core team stays close to you throughout the project.

Detail engineering

We provide detail engineering services across all disciplines. When the basic engineering is done, we put the plans into practice by specifying all the equipment and structures in detail in order to install, construct and operate the plant.


With the help of our procurement experts, you can rest assure the procurement process is valid whether the procurement is public or not. Typical services are: • procurement planning • preparation of offer requests • analyses and evaluation of bids and offers • negotiations with suppliers • purhase orders • expediting and at-site inspection of project materials and equipment • warranty issues
