Federal Minister Horst Seehofer opens bautec

On Tuesday, 18 February 2020, addressing trade visitors, exhibitors and the press, Horst Seehofer, Federal Minister of the Interior, Building and Community, opened bautec 2020. ”The construction industry is our biggest asset, it is THE driving force of the economy in Germany“, the minister said, and described it as one of the Federal Republic’s key industries. He stressed the efforts being made by policymakers to create more housing, including the billions invested by the federal government in subsidised housing. He described the government’s house purchase scheme for families as a success, which he said was leading to a rise in the share of house ownership in the Federal Republic. Making energy-efficient refurbishment a key part of the government’s climate package guaranteed support for renovation measures, he said. Enshrining these policy measures for the future would provide economic certainty for the skilled trades. “We need you,” said Seehofer, appealing to the representatives of the building industry. ”Without your ideas and innovations the country cannot take positive steps going forward.“ After his speech he cut the ribbon on the stand of the partner country Norway, thus symbolically opening bautec.


Norway is the partner country of bautec 2020

Norway is the first partner country of bautec. At the opening of the trade fair Jon Hansen, Minister Counsellor at the Royal Norwegian Embassy in Berlin, thanked the German construction industry and noted that ”Europe’s construction industry is booming. It is an important part of and vital to economic growth, and one of Europe’s biggest employers. The construction boom also brings challenges with it, as it goes hand in hand with materials causing high carbon emissions. “The buildings of the future must be constructed using less energy”, he said. Hansen emphasised that Norway was a pioneer in this respect and quoted Oslo’s new public library (Deichmanske bibliothek) as an example. This building boasts innovative features such as seawater cooling and the use of recycled, low-carbon materials. ”Norway’s architects are responsible not only for stylistically unique objects, but for sustainable designs, using renewable materials such as wood for example,“ he said, noting that the world’s tallest wooden high-rise building was in Norway. It was the country’s aim for every building site to become fossil-fuel free and produce zero emissions by 2025 and to focus on digital solutions in construction planning, he added. Visitors can gain an impression of products by Norwegian firms at the pavilion of Norway in Hall 4.2 where, among others, wood construction companies are exhibiting their products and services.

Submissions invited for the German Engineers’ Building Prize 2020

State Secretary Anne Katrin Bohle and Hans-Ullrich Kammeyer, President of the Bundesingenieurkammer (German Engineering Association), called upon the building engineers at bautec to submit their projects for the German Engineers’ Building Prize 2020. “The German engineering sector is the embodiment of innovation”, according to Anne Katrin Bohle. She pointed out that quite a few architectural innovations have only been possible because of outstanding engineering achievements. She emphasised that bautec is “THE innovation fair for you and your capabilities” and as the ideal venue for inviting submissions for this prize.

Hans-Ullrich Kammeyer called upon building engineers to make their achievements more publicly conspicuous, thereby encouraging young people to also seek careers in the building industry. Construction, innovation, energy efficiency and sustainability are the jury’s criteria, explained Petra Wesseler, President of the Federal Office for Building and Regional Planning. The deadline for submissions is 28 April 2020. The jury will announce its decision in August 2020, and the presentations will take place in Berlin at the end of November 2020. The winners will receive a cash prize and a certificate.

Component-driven demolition concepts with bauteilnetz Deutschland

The nationwide cooperative project bauteilnetz Deutschland has been set up to promote the re-use of good, used building components. This helps to reduce waste as well as cutting CO2 emissions, thereby helping to protect the climate. In recent years this association has created an online platform, a catalogue of components and nine storage or exchange sites for used building components. It is no longer the case that windows, doors or radiators obtained as a result of demolition or conversion work end up as refuse, but are stored until a user can be found. The association provides advice for public sector sponsors, municipalities, architects and construction groups about ways of developing and implementing component-driven demolition concepts. This is one way in which recycling management in the building sector can be improved.

See 3D concrete printing in action

The print head of the COBOD 3D concrete printer steadily carries out its sequence of operations as it erects curved, cavity walls. Visitors to bautec 2020 can experience this innovative technology in action on the Peri stand in Hall 3.2. With this method concrete structures can be erected quickly and cost-efficiently without the need for shuttering. The printer takes about five minutes to produce one square metre. This innovative technology ensures the accurate use of material and is also efficient in terms of the labour required, because the process would normally require two operatives. It also allows the quick and easy integration of other technical tasks such as cable ducting or the installation of insulating material. Reference projects have already been completed with the concrete printer in Dubai and Denmark.

GRÜNBAU BERLIN: The country needs new play areas

Using the Berlin district of Pankow as an example, the representatives of politics, administration and civil society met on Tuesday, 18 February 2020, at the trade fair and industry platform GRÜNBAU BERLIN to discuss the part played by public and private sponsors in the development of open spaces. Among their requirements the speakers expressed a need for more facilities suitable for all generations, the temporary closure of roads to create play areas, and inner-city spaces where the natural world can be experienced. In the past the local boroughs’ lack of funding has been one of the reasons for their failure to create or maintain play areas and green spaces. Consequently private sector sponsorship has become more important. Therefore, in increasingly densely populated cities, the intention is that urban planning contracts should be put in place requiring municipal housing companies and private property developers to incorporate open spaces in their construction projects. This would encourage families to remain in the city and help to produce a more mixed society.

Daily discussions on changing topics, addressing the planning of open spaces within the urban development context, will be taking place until 21 February 2020 in Hall 2.2 at GRÜNBAU BERLIN as part of bautec. More details can be found at


bex technologies maintains supplies

It is a familiar situation: the supply of material runs out in the middle of a job. Usually one of the trainees is sent to the builder’s merchants to obtain more supplies. This is no longer a problem, thanks to a Stuttgart-based start-up, bex technologies. One call is all that is needed, and the required material can be delivered to the construction site within two hours. Initially this service is available in Stuttgart and the surrounding area, in the Rhine-Neckar metropolitan region and the Rhine-Main region. There are already plans to extend it to other German centres of population.

Digital 3D building surveys in two minutes

Two years ago the 3D spatial scanner HottScan HS-1 received the bautec.INNOVATION AWARD. Hottgenroth has now provided its spatial scanner with a software update just in time for bautec 2020. Together with the bimCAD app this now ensures a continuous digital workflow. For building survey purposes the scanner can now provide a three-dimensional record of all spaces in just two minutes. Measurements can be conducted within a range of 5 mm to 80 m with a maximum error of 1 mm. Data can be exchanged either using a USB stick or wifi.

Careers Center bautec freshly sprayed

Shortly before the start of bautec 2020 the Berlin Painters’ Guild demonstrated its capabilities in Hall 5.2. Using a stencil that they had made specially, two trainees sprayed the letters “KarriereCenter bautec” on the floor as a highly effective way of promoting this section of the fair. The bright yellow paint certainly catches the eye. From various places in Hall 5.2 visitor attention is now drawn to this platform for training, study and advanced training for the building and building services engineering sector. One special feature is the extremely quick-drying paint supplied by Brillux, which does not require any solvents or preservative agents. The first visitors were able to walk safely over the lettering within ten minutes, and it was completely dry within an hour. This is a good example of the efficient way in which the skilled trades and industry can work together.


Honeywell Home simplifies hydraulic equalisation

Equalising the hydraulic pressure in older buildings presents a real challenge: Achieving automatic pressure equalisation is made more difficult by not knowing where all the pipes are routed, as well as by pressure losses and contamination in the pipes. The combination TRV from Honeywell is unaffected by dirt or contaminants in old heating pipe systems. The thermostat valve operates independently of the pressure in the system and regulates the volume flow, which is adapted to the input pressure directly at the radiator. The valves operate with flow rates of between 10 and 160 l/h and with a differential pressure of up to 60 kPa.
