Engineering
For our clients, engineering services from the weyer group mean complete support during all project phases, from re-
quirement-oriented process development and the design of machinery and apparatus, to ensuring fulfilment of the statu-
tory requirements in respect of the construction and operation of the plant.
In particular, the public-authority management offered by the weyer group gives our clients the necessary planning secu-
rity, since possible cost items, e.g., from the field of plant safety, can be detected at an early stage.
Particularly in the early phase of a project, important decisions have to be made which have a considerable impact on
both later investment and the operating expenses of a process plant. By including the weyer group in this phase, it is
assured that, not only in terms of costs, but also of the project schedule, optimum general conditions for the client will
be met.
