HBM : BOH, a sustainable project from design to construction.
For client Market, the leading general contractor, HBM built the foundations for BOH, a modern office building in Budapest’s new urban district. A first for our Hungarian BU both from a design and build point of view, as the design was made entirely in 3D BIM while the whole construction process was thought out with a sustainability approach.
The BOH building will be one of the prestigious buildings in the new hypermodern district in the heart of the Hungarian capital. A district combining green spaces, housing and offices.
For this project, HBM teams created a 5,551 m2 diaphragm wall. The special feature of this project is that it was carried out using a sustainable process, from the design phase through to construction.
An environmentally conscious approach
Right from the tender phase, an Environmentally conscious approach was adopted: the design teams reviewed the existing plans and proposed solutions to optimize the quantity of materials used in the structure. When choosing the materials to be installed, the main concern was to select those with the lowest carbon footprint.
In total, thanks to the rational planning method, 600 m3 of concrete, 95 tonnes of reinforcing steel and 158 ground anchors were saved. This is equivalent to a reduction of 300 tonnes of CO2! Low-carbon concrete was also used on site, eliminating a further 100 tonnes of CO2.
Limiting material and noise pollution
In addition to reducing the carbon footprint, HBM also focused on environmental protection on site. As the site is located in a relatively densely populated residential area, a hydraulic chiselling technique, which considerably reduces dust and noise pollution, was used to chisel the diaphragm wall. The concrete debris produced during chiselling was made available to the main contractor, who recycled it after appropriate pre-treatment.
The teams also saved water resources, since groundwater was used for the anchoring work, saving around 140 m3 of clean drinking water.
Congratulations to the HBM teams on this project, which is in line with the Group’s Environmental Roadmap.
