So as to be prepared as well as possible for future changes in infrastructure construction, Johann Bunte Bauunternehmung GmbH & Co. KG is engaging intensively with model-oriented working methods. The company, successful across the country and abroad, is relying here on a strategic partnership with the Stuttgart company RIB Software AG. Bunte GmbH was looking for a thoroughgoing set of software all from the same provider. The construction company struck gold with RIB, finding the system solution consisting of the programs iTWO 5D and iTWO civil. According to the head of surveying, Klaus Hemme, the RIB software is very easy to understand and allows closer and thus more productive collaboration between the departments of surveying and calculation.
So-called public-private partnerships (PPPs), in which contractually regulated collaboration takes place between public authorities and private construction companies, are strategically very important to the construction company, founded in the sixties and headquartered in Papenburg. Because the success of these and other large-scale projects – above all where cost transparency and punctuality are concerned – is becoming a greater concern politically, Bunte, as a progressive company, wants to get to grips early on with these new, digital construction methods and be ready for anything at any moment. The topic of BIM (Building Information Modeling) is no longer limited to structural engineering. The difference in civil engineering projects: The bills of quantities are usually prescribed and the volume objects are variable and significantly more complex. This makes a model-based working approach in this area more difficult than in structural engineering.
In addition, especially in PPP projects, a much larger quantity of data must be managed: As a rule, in highway engineering measures, mobile data recording of the site takes place beforehand during a fly-over or vehicle inspection, from which an enormous point cloud is generated. In addition, great quantities of data from high-resolution aerial photography are added – sometimes up to 80 items for project, which must be brought together and assessed in the course of it. Not least, PDF tendering documents add a great quantity of data. “The use of this vast quantity of electronic information brings several advantages,” surveying manager Klaus Hemme explains. “We can very easily recognize what we have to expect and to build in each location. Whether it’s woodland to be grubbed out, bus stations to be integrated or a rainwater retention basin. The large point clouds and many aerial photographs allow us to make very exact plans for construction and support us in achieving the desired results much faster. But we first have to be able to handle these large quantities of data,” he continues.
