But what exactly awaits you in the latest issue? For example, you will read how PORR's construction of the new storage reservoir in Vienna's Simmering district will protect the residents of the Simmeringer Haide neighbourhood from future floods. Or, how PORR forges entirely new paths in apprentice training with the "PORR apprentices' construction site" project in Styria and how the company was awarded the Anton-Benya-Award for it by Werner Faymann. As you can see, exciting reports await you. I wish you an interesting read and, in the name of the entire PORR group, a peaceful end of the year and a happy, successful New Year! Kind regards, Karl-Heinz Strauss CEO CEO Karl-Heinz Strauss Image: PORR AG Dear Readers, esteemed Business Partners, Welcome to the "World of PORR"! As another year draws to a close, I am happy to once again have the honour to present to you the latest issue of our specialist journal. This time, our editorial team has deliberately chosen a broad range of different projects. From building and bridge construction projects to foundation engineering projects: Fourteen new projects and nineteen update reports on existing ones are being presented to give you a comprehensive overview of the technical challenges our employees face every day. Furthermore, they showcase our approaches to finding solutions and how we master even the most complex tasks as a perfectly attuned team. I must admit that I am looking forward to every new issue of "World of Porr". Not just because it is interesting for me to see our most important projects displayed in a compact and professional way. But also because each issue marks a true joint effort: More than thirty male and female PORR experts have participated as authors in this year's edition. Considering the fact that the task of writing their specialist articles added time to their already highly busy workdays, our male and female colleagues' extraordinary commitment and dedication fills me with great pride. I Page 4 World of PORR 165/2014 PORR Projects Consortium main station B.02 Construction of the underground car park (G7) as basis for two residential buildings (G3 and G4) Andreas Samer provided a solution for both the access and storage issues. Since work on the building units G1, G2 and G6 Commissioning commenced more or less at the same time at the building In April 2013, the consortium main station B.02 – made up site, constructing in tight spaces was inevitable. of Porr Bau GmbH (commercial management) and the former Alpine Bau GmbH (technical management) was commissioned with the construction of several buildings. It received the order to construct a three-storey commercial underground car park by B.02 Garagenvermietungs GmbH. Additionally, Gemeinnützige Bau- u. Siedlungsgesellschaft MIGRA Gesellschaft m.b.H. and Wohnbauvereinigung der Gewerkschaft öffentlicher Dienst gemeinnützige GesmbH (WBV-GÖD) placed an order for two residential buildings with a total of 113 privately financed rental and freehold apartments with the consortium. The property is located at Gerhard-Bronner-Straße in Vienna's 10th district, opposite the entrance to the newly constructed Vienna main railway Position plan: Construction site conditions at building site B.02 station.

The apartment size ranges from 50 m² to 100 m². Crane concept In order to satisfy all general contractors and clients Project participants present at the site, it was necessary to work out a crane Prior to the first work deployment to the construction site, concept and to subsequently synchronise it with all the site management was made aware of the initially general contractors at the site to achieve their safety complicated client structure. This problem, however, took a distance and assure their optimal efficiency. Finally, nine turn and blew over in the course of the building process. cranes were positioned in an area of 10,000 m². The As early as from the first project meeting, the site individual cranes had to be installed correspondingly high management had to deal with the task of having to and their installation was highly complex. collaborate with three different clients, three different architecture offices, two different building service equipment planners and two different electrical consultants. Only the statical calculations and their planning for all building units were performed by one and the same civil engineering office. Building site The consortium main station B.02 also needed to familiarise itself with the confined spatial conditions: to the south, the building site is surrounded by a private road we were prohibited from using. On the other sides, it is surrounded by other building plots which meant that access and storage were a logistic problem that had to be Crane concept solved as quickly as possible. Thankfully, an adjacent Image: PORR AG plot's storage grounds could be rented due to delays which Page 5 PORR Projects World of PORR 165/2014 Execution of construction work – underground car park Turnkey construction of building units G3, G4 and G7 could begin on 8 April 2013. After a short building time, the consortium was confronted with another challenge involving the construction pit support system. Contrary to all predictions, an anchoring of the bored pile wall along the private road was not possible. Also in this case, an economical and time-saving solution for construction pit support had to be found at short notice. Swiftly, concrete reinforcements for the bored pile wall were envisaged which were finally executed by means of Construction pit reinforcement by means of concrete grates and protruding platforms the cut-and-cover method.
