Ingenia performs engineering activities for various projects, especially in the field of bio-energy, biofuels, waste treatment, circular economy, and emission reduction and odor control. Generally, engineering projects know four stages:
- Basis of Design (BOD). This is an engineering package based on the rough contours of the project, which mainly results in a product requirements document (e.g. definition of raw materials and products, available space,…) and boundary conditions (e.g. capacity, business case,…) from which a management decision can be made. A BOD also serves as a (management) benchmark for the further progress of the engineering project.
- Conceptual Engineering. This is an elaboration of the BOD where the main process steps in PFD(s), mass and energy balance and a lay-out are made in concept. Together with budget quotations and investment estimates based on key figures, the intended CAPEX and OPEX can be detailed further (typically < 20 to 30%) and used for an investment decision;
- Basic Engineering. After the investment decision, the Conceptual Engineering is further developed (i.e. P&ID’s, detailed lay-out and mass and energy balance, utilities, infrastructure, buildings,…), so that CAPEX and OPEX can be estimated in more detail (typically < 10 to 15%), multiple quotations are requested and the schedule is fixed so that in particular the time-critical and capital-intensive orders (long lead items) can be prepared and orders can be placed.
- Detail Engineering. This is engineering, predominantly electrical and mechanical (e.g. detailed drawings, piping, strength calculations, wiring diagrams,. ..)
