DG Move

Technum was awarded the DG Move contract “Study on permitting and facilitating the preparation of TEN-T core network projects, in particular waterborne projects and cross-border projects”.

The purpose of the study is to identify good practices and ways to streamline and simplify the procedures to carry out an infrastructure transport project. The study will analyse the existing legal frameworks and practices for permitting procedures, and take stock of already existing measures applied at national or regional level to make those procedures more efficient and create more legal comfort to project developers and investors. It will also prepare a guide to good practices that can be used by Member States to develop effective facilitation tools. The study will eventually recommend policy options (that can be used in a subsequent impact assessment) for a positive EU framework for project development and investments.

Our partners in this project are: Milieu Ltd, EPRD Office for Economic Policy and Regional Development

We are looking forward to implement this challenging project!

Concept Stadium Square

We tell the story of the stadium and of the city

Over time, stadium architecture has evolved as regards its relation to the city.

The first stadiums were conceived as independent facilities, often erected on the outskirts of cities.

Gradually, the city gets closer to the stadium. Urban programs start to spread into the stadium. The city’s buildings can actually get so close that they merge with the stadium infrastructure itself, generating new synergies.

The temporary nature of the stadium’s function allows the urban programs to invest the entirety of the structure.

What used to be a mere stadium now becomes the center of a new urbain life: the « Stadium Square».


We improve urban comfort


The considerable investment made for the World Cup yields a long term improvement in terms of passive comfort of the urban spaces. Dynamic thermal simulations show that the overall layout of the site, inspired from traditional housing construction in arid countries, can generate a significant improvement in the outdoor comfort, increasing air temperature during winter days and reducing it during hot summer days by up to 12°C, in both the canyon and the arena.

The architecture of the « Stadium Square » draws its inspiration from the local and regional desert landscapes. Taking both from the Zekreet in Qatar and from other geological canyon shapes, the architecture follows the principles of accumulation and erosion in order to create forms which are perfectly suited to the multiple uses of the area.



Official opening of the 1815 Memorial in Waterloo

A little less than a month before the bicentenary celebrations, the 1815 Memorial was officially opened on Thursday, May 21, 2015. The ceremony was attended by the experts from TECHNUM who worked on the project, and in particular by the Walloon Tourism Minister and the mayors of the communes where the battle took place.

TECHNUM, which was tasked with the execution studies for the structural aspects and special techniques, played a central role in the construction of the 1815 Memorial, a brand new museum dedicated to the Battle of Waterloo.

It is located at the foot of the Lion’s Mound, 10 metres below ground so as not to alter the site. The museum is highly energy efficient thanks to this special setup and the use of a geothermal facility comprising 55 shafts that reach a depth of 150 metres.

The new Battle of Waterloo Memorial covers a surface of 6000 m², 1500 of which house exhibitions dedicated to the events that unfolded in June 1815. Despite all of the legal complications surrounding the project – which was 2 years in the making – the memorial was ready on schedule. It should welcome some 500,000 visitors a year.

The peak of the tour is a 4D film projected on a 169° 26-metre-long screen. Visitors find themselves at the heart of the battle – a technical achievement that is the first of its kind in Europe.

The memorial is more of an interpretation centre than a museum, with multimedia solutions, various augmented reality systems and rather magical displays, amongst other things, punctuating the visit.

The 1815 Memorial has been open to the public since May 22.

Striking innovations at Brussels Airport.

Inauguration of the Connector

Tuesday the 24th of March, after two years of construction works, the Connector building was officially opened in the presence of King Philip, prime minister Charles Michel, minister of transport Jacqueline Galant and some 500 other guests.

The connector is the building which links the passenger terminal to Pier A above-ground.

For the design of the Connector sustainability and comfort of the passenger were very important. Each year more than 20 million passengers step through the Connector. TECHNUM who was in charge of the studies HVAC, electricity, lighting, fire safety, elevators and escalators, plumbing, access control, data communication and cold and heat storage, ... played a crucial role in the realization of the ambitions in this area. Brussels Airport seeks at a CO2 reduction of 20% for 2020. The insulation of the building is K-20, half of the current legal standard. Thanks to the geothermal installation, in the

summer Brussels Airport used the cold that is stored in the soil and the aquifer during the winter season to cool the building, while at the same time heat is stored in the soil to heat the building during the winter months. This will provide 70% of energy needs during the winter months, while in the summer, it’s providing 30% of the energy needs for cooling. With the application of waterless urinals and recuperation of the rainwater that falls on the 11,000 square meter roof for flushing the toilets is also water consumption reduced for the extremely necessary. In the field of lighting there was resolutely opted for LED lighting in the public areas allowing both energy consumption and maintenance costs to drastically reduce.


The Connector designed by CTHM (Chapman Taylor – bureau Happold – MOSS) allows passengers to walk straight from the check-in desk to their gate in pier A. In the opposite direction, the building provides the arriving passenger with a smooth and agreeable passage to the baggage reclaim hall and the exit. The dark tunnel towards pier A is now replaced by an open and airy building that apart from a spectacular tarmac view also offers a contemporary mix of shops and restaurants.

From now on the Connector is open for passengers.

The building includes a central platform for access and security screening as well as border control for travellers departing Pier A. Passengers departing from Pier B will use the platfrom as of 2016. This considerably increases the efficiency of the screening process, as the peak hours for security in both piers are complementary. Moreover, the building offers plenty of space for a commercial area.

The challenge was huge: the construction site was located in the centre of a busy international airport, which had to remain fully operational throughout the building works without compromising passenger comfort.




FEBE Precast in Infrastructure Award for radar tower in Ostend

The new radar tower on the recent Oostdam in Ostend, Belgium, has won the FEBE Precast in Infrastructure Award.

On behalf of our client, the Maritime Access department of the Ministry of Mobility and Public Works of the Flemish Government, we developed the detailed design for the 44-m high tower built after a design by the architect E+W Eggermont at level. This success was founded on close cooperation between our (SSI) department Ports & Waterways, the Hasselt-based Structures competence centre and the government.

The tower is prism-shaped up to a height of 30 m, after which it is twisted. It was constructed by stacking up 22 prefabricated concrete segments which were progressively post-tensioned. The twisted top section was reinforced in the conventional manner. In order to make the design suitable for prefabrication, the spatial shape was converted into a series of triangles. The actual production of the prefabricated elements, as well as the laying of the post-tensioning ducts and their positioning were subject to extremely stringent tolerance requirements. The contractor THV Besix-Westconstruct constructed the tower.








From 19 to 21 May, 2014 Technum attended the Realty property exhibition, which welcomed more than 3,500 participants.

This exhibition was held in Tour & Taxis in Brussels.
