We previously wrote about the use of sustainable raw materials for concrete construction. Pelecon was the first in the Netherlands to apply “Freement” in the construction design of a building foundation. Freement is a recycled type of concrete. In addition to durable concrete, it is also increasingly common to use durable steel of higher quality in a steel construction.

We previously wrote about the use of sustainable raw materials for concrete construction. Pelecon was the first in the Netherlands to apply “Freement” in the construction design of a building foundation. Freement is a recycled type of concrete. In addition to durable concrete, it is also increasingly common to use durable steel of higher quality in a steel construction.

Advantages of steel qualities S235 – S35

The material costs for the production of steel grades S235 – S355 are roughly the same. By continuously increasing the production of high quality steel, the costs converge. The current cost ratio in the market between S235 and S355 is approx. 2-5% more expensive for the higher quality. The strength capacity of S355 is 50% stronger compared to S235 steel. By using S355 steel instead of S235 steel in the calculation design, the steel weight of a building structure can be reduced by approximately 20-25%, which is a direct cost and environmental saving

Energy neutral

A steel construction element is dimensionally and wear resistant. Because it can be built tightly, the end result of the structure is airtight. Which, of course, together with good insulation and the installation of solar panels, ensures an ultimately energy-neutral building

Lower environmental impact

Steel is manufactured industrially, there is little or no construction waste. But there are more reasons why sustainable steel has a lower environmental impact.

1. De- and remountable

It is very easy to reuse steel. Then there must be a simple design from which the steel can be disassembled. At Pelecon we are already working within our latest construction designs to design the steel construction in combination with floor elements de- and remontabal.

2. Database for buildings

Another important part is the creation of a database for buildings that we are going to build now and in the future. The current buildings are fully BIM engineered. This means that all building elements can be easily traced back to size and quality. If the building is at the end of its life, the building elements can be selected by means of the BIM models. They can be given a second life in another building or work of art.

3. Biocoat

What also contributes to sustainability is coating the steel structure with an indoor climate by means of Biocoat. This transparent coating of steel structures gives the steel a robust and natural look. This coating is more environmentally friendly than traditional coatings. (www.circulairstaal.nl)

4. Skellet

A sustainable way of building can be done by applying the “Skellet building system”. A Skellet profile has holes on a grid of 25 mm that are used to connect the profiles by means of blind rivets. The Skellet building system therefore only consists of bolted and riveted connections that can be assembled and disassembled without damaging the connecting pieces. The result is dimensional stability and flexibility in design and during construction and the possibility to reuse the profiles. (www.skellet.com)

Positive influence on environmental savings

In short: Today’s steel constructions have an increasingly smaller impact on the environment during the production of the building components up to and including dismantling and recycling or reuse. Pelecon always takes durable steel structures into account when designing. After all, sustainability is a keyword for the future in construction!

THE FOUNDATION, OR FOUNDATION OF A BUILDING, ENSURES THAT THE WEIGHT OF THE BUILDING IS TRANSFERRED TO THE LOADING SUBSTRATE AND / OR POSTS. AT PELECON WE ADVISE PROJECT DEVELOPERS, ARCHITECTS AND CONSTRUCTION COMPANIES ON THE APPLICATION OF CONCRETE FOUNDATIONS, among other things. IN WHICH WE LATTY RECOMMEND THE SUSTAINABLE FOUNDATION, ALSO “FREEMENT”, MORE OFTEN. BUT WHAT IS THAT FREEMENT CONCRETE ACTUALLY?

After water, concrete is the most used product in the world and is made up of the raw materials gravel, sand and cement. A great product, but almost 9 percent of global CO2 emissions originate from concrete. Freement has been developed to reduce this figure. Freement is a circular concrete mortar where recycled cement is used. This is extracted from concrete rubble from demolition buildings.

RECYCLING CONCRETE

Recycling of concrete has been going on for as long as concrete has been used. In the form of rubble granulate, this product serves as a substrate for road construction, among other things. This residual flow is seen as a low-value residual product. Unlike traditional coarse concrete crushers, the Smart Liberator subtly rubs and turns cement stone from concrete debris and “liberates” it into reusable cement. This makes the original components reusable, so that the cement part in particular can again serve as a high-quality product. By re-adding gravel and sand, the correct dosage is again created and ultimately the recycled concrete: “Freement”. The worldwide application of the circular Freement results in up to nine percent less CO2 emissions. And it fully fits in with the ever-increasing desire to build as sustainably as possible.

PELECON APPLIES FREEMENT IN ADVICE

Pelecon was the first in the Netherlands to use this type of concrete in the construction design of a building foundation. We are very enthusiastic about this type of concrete and will therefore always include it in our advice as a potential sustainability solution. But it does not stop there, we generally continue to look for smart solutions to make the buildings for which we constructively calculate increasingly sustainable. After all, we never sit still!

Inspiring order for new departure hall Rotterdam The Hague Airport

Geplaatst op: 9 June 2020

Because the old departure hall of Rotterdam The Hague Airport from 1970 was outdated and became too small, a new terminal was needed. A terminal with a much larger capacity, but which must fit well with the character and appearance of the airport. Not a megalomaniacal anonymous building, but a pleasant building with lots of natural light, intended to make passengers feel comfortable. A sustainable building too, including a moss sedum roof.

Pelecon inspired this ambition! We were therefore happy to participate in the planning and implementation of this project. In a team of architects, contractors and suppliers of all materials, we advised on the more than 100 tons of steel, the laminated roof beams and approximately 4,000 steel bolts that have been incorporated into the steel construction of the new departure hall of Rotterdam The Hague Airport.

In addition, in the existing building of Rotterdam The Hague Airport, what has been preserved, many structural changes have been made and improvements have been made. Pelecon received the ‘constructive puzzle’ of the existing building, where a number of details were established:
1: the existing mezzanine, which includes Grand Café De Horizon, is located at 3.10m + level,
2: the underlying ground floor needs an internal height of at least 2.60m +,
3: the existing storey floors are constructed from a thin concrete floor resting on steel beams.

We had to get a lot of new piping for the E, W & sprinkler installation through these existing steel beams for which more than 200 openings had to be created. The puzzle has been laid, partly due to the frequent coordination between the installer Engie, contractor Volker Wessels Bouw Schiphol and Pelecon.

We are proud of the immense issue we have answered for the Rotterdam The Hague Airport project in which we have made a big difference in our field. The departure hall will be put into use at the end of this year.

Recently a nice article for this project was published in the magazine “Industry Construction” of May 2020. Click here to download the magazine.
