Digital construction is no longer a vision of the future, but an everyday reality on construction sites. Today, technology saves time, costs and the environment. The international construction group HSF System from the PURPOSIA Group deploys drones, 3D printing and advanced digitalization to make construction processes faster, more accurate and more efficient. The result is savings, efficiency and more sustainable construction. As a result, the HSF System Construction Group has fundamentally transformed the way it designs, manages and delivers construction in recent years.
Digital construction management
All construction production is digitally controlled in HSF System. The digitalization started with methodologies, continued into design and is currently in the process of being integrated into sales and budgeting. The result is faster data sharing, better teamwork and greater transparency towards investors. “We are also digitising tenders. Subcontractors are thus seamlessly joining our digitalisation, often without having to change their working habits,” says Miroslav Krop, Plant Director Ostrava, HSF System.
Soil balance: a cost-saving technical detail
One of the key tools for efficient construction is a properly performed soil balance. It allows you to optimise excavations and embankments before construction begins. “With a properly processed balance, we can assemble the building without the need for unnecessary removal or import of soil, which significantly saves not only costs, but also the impact on the environment,” points out Tomáš Mydlo, Production Director, HSF System SK. The key tool is terrain modelling in Revit software and drone surveying. “Within moments we have an accurate digital model of any terrain,” says Marián Postředník, Construction Manager, HSF System. On one project, for example, the drone data revealed three times the amount of soil compared to the original documentation. Thanks to early intervention, major financial losses were avoided.
Drone inspection: inspection from above
HSF System uses drones not only for ground surveying but also for roof and facade inspections. With a thermal imaging camera, thermal bridges or faults are easily detected before they become visible on the outside. “A thermal image shows differences that may indicate a fault, poor assembly or a defective component. This way we are able to detect a fault before it fully manifests itself,” describes the benefit of drone inspection Tomáš Čarný, Facility Manager, SK Facility. The result is a quick and efficient plotting of risk areas directly on the construction drawing. Drones also help in cleaning facades, measuring the volume of dumps or optical inspections in hard-to-reach places.
Total Station: smart precision control
Without precision, there is no efficient construction. Today, total stations allow you to measure heights, distances and positions to within centimetres without having to wait for an external surveyor. “Sewer or water delineation is performed by a trained worker based on data from a licensed surveyor. We don’t have to have a surveyor on site every day, which significantly reduces costs,” explains Tomas Mydlo.
Unique Czech patent for 3D printing of concrete
HSF System has established a strategic cooperation with ICE Industrial Services from the MTX Group holding. The result is Coral Construction Technologies, which specializes in automated 3D printing of concrete elements and structures. ICE Industrial brings know-how in automation and engineering, HSF System expertise in construction. Together they bring to the market a unique Czech patent for 3D printing of concrete. One of the most interesting projects is the new church and rectory in Neratovice, where a 3D printed bell tower with a height of 22.8 metres will be the dominant feature. Thanks to its atypical shape, 3D printing is an ideal solution that will enable the precise and efficient realisation of a complex structure.
Research and development: from industrial flooring to renewable energy
HSF System works with universities to develop smart solutions for energy efficiency and new types of construction. With VŠB-TU Ostrava it develops new types of industrial floors, with the University of Žilina it focuses on energy flexibility of buildings and the use of renewable energy sources.
