Examples of Allplan Engineering and impressive projects around the world.
THREE CENTURIES OF BRIDGE BUILDING OVER THE FIRTH OF FORTH
Reinforced concrete pylon with cablestayed tensioning and suspended roadway during the construction phase.
The Queensferry Crossing near Edinburgh in Scotland is a cablestayed bridge with three pylons over 200 m in height. It is one of the largest infrastructure projects in Europe and benefitted from ultramodern reinforcement planning in 3D thanks to the engineers from Leonhardt, Andrä und Partner (LAP) and Allplan Engineering.
Transport Scotland’s consultants from the Jacobs Arup joint venture were not given an easy task in developing a concept for the new bridge. The bridge has to be an equal counterpart to the world cultural heritage of the "Forth Bridge."
The reinforcement of the individual pylon segments had to be placed precisely in the space due to the upwardtapering crosssection. This method placed high demands on the CAD software used. That is why planners from LAP also relied on Allplan Engineering for the reinforcement and...
FUNCTION AND DESIGN – XXL
Sava Bridge, Belgrade / Serbia
Belgrade lies at the confluence of the Danube and Sava rivers. For years, expansion of the northern suburbs of the city has been hindered by the limited capacity of the three existing bridges over the Sava: the Brankov most, Savski most, and Gazela. In order to expand the capacity of the transport network, a fourth bridge is currently being built over the Sava.
The project is a complex one, and not only because of the dimensions involved. In order to ensure uninterrupted shipping movements during the construction period, the main section spanning the Sava must be erected in the river without temporary supports. In addition, construction will be going ahead on different sections simultaneously. The side section, for example, will be erected parallel to the main bridge, yet independently of it.
Depending on the specific need, the engineers have combined 2D and 3D planning, a classic example of hybrid working. “For the typical standard tasks in the planning of bridges, 2D planning is entirely sufficient, but more complex points are nowadays being planned increasingly in 3D,” states Steffen Kühn, structural designer at Leonhardt, Andrä and Partner. Formwork and tendon stress planning, for example, have been carried out in 2D, while 3D planning...
BRIDGING THE GAP FOR MORE THAN A CENTURY
Versamertobel Bridge, Graubünden Canton, Switzerland
As an example of steel bridge building at the turn of the century, the structure is of considerable historic value, but it is no longer up to the demands of current times. The bridge has been deemed worthy of preservation and therefore has escaped being torn down and instead continues to serve the traveler as an additional link for slower traffic.
The brief had to consider the dramatic surroundings, the slender lines of the adjacent existing steel bridge, the difficulties of construction and the requirements for durability.
All the drawings were prepared using the BIM solution Allplan, which confirmed in particular on this project its credentials as an easy-to-use, intuitive 3D design tool. This was apparent in considering the steep ground around the foundation excavations, at the connection of the...
Campus Bridge Würzburg, Germany
There is more behind the “campus bridge” than the pure avoidance of stopping traffic. The new university campus Hubland North is located on a former US military base: the Leighton area. After the US forces left this in 2009, the state of Bavaria purchased part of the land for the University of Würzburg and had parts of the former military facility converted for university use.
The team of Dr. Schütz Ingenieure (Kempten), Kolb Ripke Architekten and POLA Landschaftsarchitekten (both Berlin) created a design that was implemented in a single-stage realization competition at the turn of the year 2011/2012: a sophisticated structure, consisting of two narrow concrete strips converging into a small square above the street.
Dr. Schütz Ingenieure used Allplan Engineering to model the iconic structure. With Allplan Engineering software, it was possible to optimally illustrate the complexity of the bridge in the 3D modeling. In the process, the 3D modeling of reinforcement drawings in particular contributed to...
Skyscraper with unconventional building geometry
Limmat Tower Dietikon, Switzerland
With the 80 meter high Limmat Tower, the Limmat Valley in Switzerland has its first skyscraper, which could become the landmark of the town of Dietikon, or the whole region. "The Limmat Tower stands for innovation, uniqueness and prospect," said Maik Neuhaus, head of development at Halter AG, at the turf-cutting ceremony in June 2013.
Direct force transmission was impossible in various places due to the façade folding and the projections and recesses. The support forces also needed to be absorbed or diverted at the building recesses. And, in terms of fire protection, in high-rise buildings the fire must be prevented from spreading by the circumferential parapet.
Thanks to the model-based development of the formwork and reinforcement plans with the Allplan Engineering software and the possibility of 3D visualisation, the engineering firm Synaxis was able to optimally deal with the sophisticated details in particular in a way that suited the construction site.
Software-assisted planning competence assures high quality standard
When compared internationally, engineering offices are expected to cope with high demands. This can only be achieved by maintaining permanent willingness to innovate and it demands continuous examination of the latest technical trends. MUCKINGENIEURE has an excellent track record when it comes to planning complex building structures using Allplan Engineering.
The common aim is to produce a construction plan that is an economic success.
MUCKINGENIEURE works using a 3D BIM model and stored attributes to increase flexibility in the face of requested changes and as a reliable method of verifying their feasibility. The engineers normally draw up lists and attributes themselves, since Allplan Engineering offers the opportunity to program individual reports, or save components and their properties.
Shining debut for a new city quartier
Office building Aviatica, Prague, Czech Republic
The former factory premises of aircraft engine manufacturer Waltrovka / Walter Engines is located in the district of Jinonice, in the fifth administrative department of Prague. Investment management group Penta Investments is planning to build a new city quarter with three office complexes (Aviatica, Dynamica and Mechanica) and various residential complexes on this 169,000 m² site in the coming years.
From the prestressing of the concrete beam and the vibration isolation through to the different pillar patterns between the underground and overground stories, the project involved many technical construction tasks that the engineers would normally have tackled in separate teams with different software solutions.
The company used solutions from Allplan and SCIA from Nemetschek for this. The shell or reinforcement plan was created with the help of Allplan Engineering, and modeling and calculations were carried out in SCIA Engineer.
Aesthetic shell for regenerative energy
Hydroelectric power station, Kempten
The new run-of-the-river power plant on the Iller river at Kempten impresses the viewer with its dynamic, elegant form. The almost 100 meter long sculptural shell conjures up numerous associations: from whales or waves through to polished boulders. The power plant replaces a building from the 1950s and currently supplies around 4,000 households with a capacity of around 14 gigawatt hours per year.
In a competition, the building client, Allgäuer Überlandwerk (AÜW) Kempten, requested a building design to harmonize with the protected group of buildings opposite, comprising the former Rosenau spinning works and weaving works.
The organically shaped shell of the hydroelectric power plant was created with a very high level of detail with
Allplan Engineering and provided the optimum basis for shell and reinforcement plans.
A2 Freeway, Stansstad-Beckenried, Switzerland
For all those involved in the project, repairs to the 12-kilometer section of the A2 freeway between Stansstad and Beckenried is a particular challenge. Between 2013 and 2017, the section of road, which has been in use for 40 years, will be redeveloped in three construction stages at a cost of around 278 million francs.
The repair work must be carried out within a short space of time, among traffic, and in very tight spaces on site. To meet these demands, the repair work on the Stansstad section to freeway exit Stans Süd, including the preferred measures, has been divided into six phases. It is only necessary to close freeway entrances and exits for a short time during resurfacing work.
The project placed high demands on the accuracy of the installation of the new road surface. With Allplan Highway, it was possible to meet these demands very efficiently.
Aare bridge, Olten (SO) Switzerland
Olten has a new landmark: the Aare Bridge, which was given over to traffic in April 2013 as part of the "Olten Region Relief" (Entlastung Region Olten, ERO) project. Thanks to the 3D visualization, the planning association commissioned to manage the project were able to show that the main intersections of the static system could meet all requirements relating to the installation of reinforcements and pre-tensioning measures, despite their minimal dimensions.
The main challenge for reinforcement and pre-tensioning was at the highest point of the structure: The longitudinal beams (which act as a link to the cut-and-cover tunnel), the angled support (which stands on the abutment), and the concrete sail (which braces the bridge's longest support) come together here on both outer sides.
The reinforcement and pre-tensioning plans for this level of complexity in the structure could only be tested in the 3D model...
Three bridge project in Nijmegen, Netherlands
The Dutch in Nijmegen reveal just how sustainable and pioneering flood protection can be with an impressive project. Just across the border from Germany in the Lower Rhine, Europe's largest flood protection project is under construction. It is called "Ruimte voor de Waal" – literally "more room for the Waal" – and is intended to create more space for the biggest river in the Netherlands, the Waal.
For the engineers in charge at Witteveen + Bos, bridge building on this scale is an enormous challenge, especially as the timetable has been tight from the start. Planning such a major project without errors in such an incredibly short time is only possible – and the Dutch engineers were in full agreement – with hard work and the latest equipment.
With Building Information Modeling (BIM) as an efficient planning method, and with Allplan Engineering as the right tool it is extremely beneficial because all the necessary information can be derived directly and coherently.
All wrapped up
Elephant house Zurich Zoo, Switzerland
The new Kaeng Krachan Elephant Park at Zurich Zoo is a fine example of the international change taking place in zoo philosophy: More space for elephants, more proximity for visitors. The new home for a family of eight elephants extends over an area of more than 11,000 m². This is approximately six times the size of the old facility and provides the animals with more space, more family life and more room for movement.
The project was a daring experiment because a roof structure like this, with spans of over 85 meters, had never been built before.
For many years, Walt + Galmarini has consistently relied on the BIM solution Allplan Engineering for realizing challenging designs with a high degree of quality. Once the digital building model has been populated with the design data, the engineers can derive all the relevant sections, views and perspectives.
NICE AND SLENDER OVER THE VALLEY
Railway bridge Grubental, traffic project German unity 8.1, Germany
The section of the new line Ebensfeld-Erfurt was planned by the engineering office schlaich bergermann partner and was carried out by the Goldisthal Railway Bridge consortium (Bickhardt Bau AG and Ed. Züblin AG). Situated about five kilometers southwest of Goldisthal in the Thuringian Forest, the 215-meter long structure spans the Grubental Valley at a maximum height of 35 meters and connects the Goldberg Tunnel with the Dunkeltal Bridge.
That's how easy and elegant the Grubental Bridge is, how sophisticated its design is. After all, it was necessary to bridge a narrow valley bordered by steep slopes at an angle of about 50 degrees.
Thanks to Allplan Engineering, it was possible to record the difficult terrain situation in a digital terrain model (DTM) in no time. For this purpose, the measurement data provided by the client was...
