“The south expansion will be a significant upgrade for Vienna Airport and passengers will enjoy a much more comfortable stay. With this expansion, PORR is demonstrating its expertise in handling extremely complex construction processes”, says PORR CEO Karl-Heinz Strauss. Modern, open and spacious common areas, new lounges, extensive areas for eating, drinking and shopping, as well as 18 bus gates will be developed on an area spanning 70,000m2. The wide-span glass facade serves as a “window to the world”. The increase in available space will not only elevate the quality of the passenger experience but will also direct passenger flows more efficiently. This challenging large-scale project requires detailed fine-tuning before construction begins, along with integration of the data into a 3D BIM model, and exceptionally streamlined process management.
BIM, LEAN and Augmented Reality
With its subsidiary pde Integrale Planung GmbH, PORR has opted for early contractor involvement. “The construction companies are already cooperating right from the design and planning phase and can suggest changes so that projects can be realised more cost-effectively and efficiently”, said Strauss. For example, the structural design of the roof construction has been optimised versus the original concept so that it can be realised more easily and with lower material costs.
PORR also relies on LEAN Design and LEAN Construction to organise all processes as efficiently as possible. This is because the LEAN management approach allows users to make continuous adjustments during the design and build phases, inputted by the actual workforce, in order to improve the construction process. In addition, a 3D BIM model is created for the entire airport building, giving all those involved access to the data. This makes any collaboration much more transparent and fluid. Being linked to BIM also enables the use of GPS-controlled excavators, as well as allowing surveying work to be carried out with a 3D model without a surveyor and making it possible for any defects to be recorded using augmented reality. Different variants of facade sampling can also be visualised on the BIM model itself using virtual reality.
