Engineering to the power of X

Founded in 2012 as a general planner, we have developed into a company dedicated to developing and perfecting innovative methods in the planning and construction process. Our most significant operation method is Building Information Modelling (BIM). This integrative method has been established and continually perfected within the PORR Group for several years now, helping to promptly mitigate planning errors and precisely calculate costs. We also guarantee the highest degree of transparency for the employer: involvement in the planning stages allows the client to follow the three-dimensional emergence of the object virtually.

In combination with LEAN Management, we are thus able to ensure not only excellent planning quality, but also stable costs and schedules for the most challenging projects in terms of technology, architecture, budget and deadline compliance.

As a multi-engineering company we offer more than just general planning. We never look at one work phase of a project in isolation, instead considering the whole life cycle. Accordingly, we maintain a close dialogue with the specialist teams responsible for the upstream and downstream work stages, and in so doing, lay the best possible foundations for the production and service life of a building.In all our projects we undertake to preserve the design concept, plan economically and carry out the required processes efficiently. By using BIM, we are introducing new planning standards, considering sustainable aspects at an early stage and laying the groundwork for innovative and long-lasting constructions. If so desired, our specialists are able to support construction implementation right through to the handing over of the keys.

We are PORR Design & Engineering.
