Re-Use and Recycling Forum New life for building materials

How can building materials be re-used more effectively and how can ecological building be made more sustainable? This was the question that was investigated by speakers at the Re-Use and Recycling Forum on Wednesday, 19 February, at bautec. As Berlin’s State Secretary for the Environment and Climate Protection, Stefan Tidow, pointed out: “It is important for us to build in an ecologically intelligent and sustainable way. If we consider the amount of resources used in building and the amount of waste produced when we demolish buildings, it is obvious that we need a transitional approach to resources and we must also build more intelligently. This means making use of the materials that we are taking down in order to be able to use them again as raw materials in subsequent building work.“  The authorities are setting a good example with their building and renovation projects in Berlin. “With our administrative provisions for the environment and procurement we have made arrangements for the increased use of wood and recycled concrete in buildings, and this has to be taken into consideration in public invitations to tender”, explained Stefan Tidow.

At the Re-Use and Recycling show in Hall 2.2 at bautec in Hall 2.2 the Senate Department for the Environment, Transport and Climate Protection, together with a number of partners, is demonstrating for the first time how modern recycling management that conserves resources can be implemented in the case of building work, It is using this event to recommend suitable courses of action to architects and builders.


Lidl at bautec: living above the supermarket

Early 2020 sees the start of building work on the modern and sustainable Lidl branch in Berlin-Mahlsdorf, which also includes 26 apartments. To ensure that it can be completed in less than a year the building is of modular construction. Lidl is making its first appearance at bautec as a partner for innovative building aspects such as serial and modular construction, and is presenting the first of these projects at the fair. “We are aiming to be the first choice partner for companies in the property sector”, explains Jan Brenn, General Manager for Branch Expansion and Branch Construction for Lidl Germany. “Consequently our aim is to present our flexible concepts for our outlets to an audience of experts, to acquire partners to share in the development of our projects, and to encourage joint innovation in construction work, especially with regard to the important issues of sustainability and digitalisation.” Lidl also has a presence at the Careers Center bautec in Hall 5.2, where it is focusing on the benefits it can offer as an employer in the property sector.

Using artificial intelligence to aid densification

At the Smart City Forum with its focus on “Digital – Collaborative – Sustainable” that took place on Tuesday (18.2.) at the Building Practice Centre in Hall 3.2 at bautec, contributors included the architect Tobias Nolte from the Berlin practice Certain Measures – Office for Design Science, with methods of seeing and designing by machine. “We are not concerned with recycling”, said Tobias Nolte, “but with redistribution. In other words, arranging things in a new and possibly better way.” He has been involved in the development of a form of artificial intelligence (AI) that can design something completely new, using individual parts. In the first version the architect and his team have made the working processes of an algorithm into a sensory perception. The traditional approach has been to create a concept and then produce it. Nolte’s algorithm reverses the process and considers the resources. The “mechanical eye” of his AI registers the available material and plans its re-use. In this way, and with the aid of Big Data, completely new objects can be created from building waste. An impressive practical example is provided by the chalet project from Certain Measures entitled ‘Cloudfill’: A chalet in Berlin was completely dismantled and each individual component was digitally recorded by means of AI, from single screws to the toaster, the bird cage and the floral wallpaper. In the next step AI was used to re-assemble the individual pieces like a puzzle, to create something new, in this case a new and futuristic chalet, which is now being exhibited in a museum.

However, this technology also has very practical applications, such as the densification of urban spaces. For example, Certain Measures has digitalised all the layout plans for Los Angeles and the AI has search this database for potential spaces in which to erect so-called tiny houses. Given the pressure to build new houses in large cities and urban conglomerations, this process could make a useful contribution to ecologically acceptable densification.


Management of building defects goes BIM

The web-based SaaS solution PlanRadar facilitates the documentation and management of tasks and defects. This mobile system enables details about construction sites and buildings to be easily and rapidly acquired using a smartphone or tablet. In one singe process images, texts, dates, voice memos and precise positions can be entered on a digital plan, even if the device is offline. All the defects or orders that have been registered can be passed on to the relevant contractor at the press of a button, along with the completion date and priority. All communication by all those involved takes place within the system or by email. This ensures that the project is GDPR-compliant in all respects and is documented with an unalterable record. 


Start-up Area: New solutions for digital construction

In Hall 4.2 bautec’s new Start-up Area is where startups are exhibiting innovative, practical and digital solutions for the construction industry. One of the companies is myCraftnote from Waldachtal. Using a function similar to WhatsApp, Craftnote’s app for members of the skilled trades helps document the services they perform and communications between those involved. Cosuno’s software solution makes it easier for general contractors, developers, architects and planners to manage tenders. Companies can search for offers on this cloud-based platform and make decisions based on the data obtained. Tenera from Berlin is marketing a similar solution. Their software helps developers to speed up project planning, keep to deadlines maintain an overview of offers.
