It was 8 years ago this week that plane MH17 crashed, killing all 298 people on board. It is still an immeasurable loss for thousands of surviving relatives. The Stichting Nationaal Monument MH17 wanted to give a place to these feelings – an ambition that has been realised thanks to the efforts of many. Pelecon had the honour of making the structural calculation of the memorial.

The MH17 National Monument is a special landscape object that aims to keep the memory of the 298 victims alive. In the park-like oasis, 298 trees have been planted in a green ribbon in memory of the victims; one for each victim. A place that binds together and serves as an oasis of reflection, comfort and hope. Surrounded by a wreath of sunflowers, with an intimate amphitheatre and an impressive memorial.

Would you like to know more about the monument or visit it? On the website of the Monument you will find more information.

That a team day is important was something we experienced last week! With all our colleagues from Gouda and Amersfoort, we put our talents on edge. Our focus was on all individual talents. What are everyone’s strengths, weaknesses, where can we strengthen each other, where do our individual colleagues need to grow to become an even stronger team? Which role fits like a glove and how do these roles relate to each other? And not unimportantly: what is the goal of Pelecon?

It was nice to see how all colleagues criticised themselves and each other in a polite way, so that at the end of the day we had valuable input for the future. So that we can grow as a team and become even better at our work than we already are! We look back on an inspiring day and look forward to a successful future!

Model terminal building Rotterdam The Hague Airport

Geplaatst op: 27 June 2022

PELECON HAS BEEN LOYAL TO ROTTERDAM THE HAGUE AIRPORT FOR AROUND 25 YEARS. WE ARE INVOLVED IN VARIOUS CONSTRUCTION PROJECTS AS A STRUCTURAL ENGINEER, FROM SMALL ALTERATIONS SUCH AS THE TERMINAL AND HANGAR BUILDINGS TO MAJOR ALTERATIONS SUCH AS THE NEW DEPARTURE HALL. RECENTLY WE WERE ALSO ALLOWED TO MODEL THE ENTIRE STRUCTURAL PART OF THE EXISTING TERMINAL BUILDING FOR SCHIPHOL, OWNER OF ROTTERDAM THE HAGUE AIRPORT. WE BUILT THIS IN COLLABORATION WITH ROYAL HASKONING DHV, WHICH MODELLED THE STRUCTURAL AND INSTALLATION ENGINEERING PART OF THE JOB.

The existing terminal building was built in the 1960s. In the period up to now, major and minor renovations have been carried out within and next to the terminal building, many of which we have worked out in 2D (autocad) or on sketch over the past 25 years. Our modellers used all this data as a basis for building the new, constructive model. A point cloud was also created, with which we could visually check the constructive model to determine whether the construction model fits! The model is built according to BIM basis ILS 2.0 with LOD300 as the elaboration level.

The building model was recently presented and delivered to the client. The building models made (constructive, architectural and installations) serve as a basis for future designs for internal and external renovations and to support the technical service Rotterdam The Hague Airport.

Renewal construction of cultural center Noordam in Amstelveen

Geplaatst op: 23 June 2022

The process of renovating the Noordam cultural center in Amstelveen started with sky-high ambitions; columns had to go, the skylight became a diamond-shaped museum construction and the stage tower had to be of the Carré caliber. Obviously a challenge for us as engineers, but during the consultation with the client (the municipality of Amstelveen) it soon became clear that we had to be more careful with the available budget. And that usually means choosing. Fortunately, the architect was also convinced, so that we could focus all our attention on the new building. With reference to the old school that once stood on that site, two pointed roofs emerged from the design, with a facade that would open further and further. Large spans and little space for construction.

We have indicated the options with a number of sketches. And the solution always is: if it becomes constructively difficult; then turn the span direction. In this way we were able to absorb a lot with a few heavy constructions, including stability. And the facade could be constructed very finely against the existing theater with very slender steel portals. A lot still had to be done for the new sustainable technology (heat pumps, etc.), but no visitor will see that construction in the design. That is indeed the invisible force.

Construction solutions at a growing number of distribution centers

Geplaatst op: 22 June 2022

“VERDOZING”, A TERM COMMONLY USED IN REAL ESTATE IN THE NETERHERLANDS. IT MEANS THAT THE DUTCH LANDSCAPE CONTAINS A HIGH NUMBER OF DISTRIBUTION CENTERS AND THAT THEY ARE STILL BUILDING FANATICALLY. IT IS NECESSARY, BECAUSE OUR GROWING ECONOMY AND EXTENDED AUTOMATION IS DOING GREAT. BUT IT ALSO INCREASES THE CONVERSATION ABOUT HOW SPACE RELATES TO ECONOMIC VALUE AND SUSTAINABLE DEVELOPMENT. AND THEN AN IMPORTANT POINT: WHAT DO ALL THESE DISTRIBUTION CENTERS DO WITH THE LANDSCAPE? WHAT ARE POSSIBLE SOLUTIONS AND WHAT IS OUR ROLE AS A MANUFACTURER WITHIN THIS ISSUE?

A first possible solution for “verdozen” is to cluster buildings in one place, not only horizontally but also vertically. We use as little area of ​​the landscape as possible so that we can stay far enough away from the ‘inhabited world’. Stacking requires radical technical solutions. Where we used to pack ‘air’, we now have to deal with a lot of technology inside the distribution centers, which entails weight. In this case, a correct construction not only guarantees the safety of the building, but also ensures that the distribution center can be set up and used as optimally as possible.

SUSTAINABILITY FUNCTION
A second possible solution is to give distribution centers a sustainability function. For example as an energy generator. Why not fill the roofs with solar panels that provide the adjacent residential area with energy and perhaps also with (rain) water? For a constructor, this presents a new challenge for the roof construction, because solar panels require a different calculation than a standard roof.

ARCHITECTURAL SOLUTIONS
The beauty of the landscape is also part of the discussion. Architectural solutions for distribution centers are in their infancy. Our challenge is to find the most suitable solution for this. An example: we can integrate the distribution center with the parking and the bypass around the building. Covering this with greenery and shielding it with trees makes the appearance of the distribution center much more friendly! In addition, if you integrate the parking lot into the building, the total surface area of ​​the distribution center can be reduced by a quarter. And how about building housing for employees against the blind facade of a distribution center? For us as a constructor, these are the challenges within our field, because we have to give a building multiple functions, each with their own construction needs.

Would you like to spar with us about the dulling of the landscape? About how we, as a constructor, can think along in a solution to your dilemma about the still growing number of distribution centers? Feel free to contact us.

We got inspiration for this topic from an article in Vastgoed Journaal.

Construction calculation for mos sedum roofs

Geplaatst op: 20 May 2022

Every now and then we make advice for an unusual project. For example, we recently made a construction calculation for the roof floors of 44 life-resistant homes in Zwijndrecht. Moss sedum is applied to this and testing of this addition of load with a control calculation is necessary. This means that we calculated the existing concrete roof floors, whereby we tested whether the existing reinforcement is sufficient. We also tested the foundation of the houses for this greater load.

We approved both the foundation and the roofs!

Column André Verschoor about time, cost savings and sustainability

Geplaatst op: 20 May 2022

Our colleague André Verschoor recently wrote a column for the professional magazine Bouwen met Staal. This is about the acceleration of the execution of construction projects. The costs to be saved during the design process. Both put a lot of pressure on a sustainable design. So that’s where the big profit lies; extra attention to the design, calculations, coordination and the intended detailing. Could we also rate engineering services with stars?

Curious? Read the full column.

A tailor-made suit for ladieswear brand Studio Anneloes

Geplaatst op: 14 April 2022

Recently, the new office building of Dutch women’s clothing brand Studio Anneloes in Amsterdam Osdorp was completed. Together with Heembouw Architects and contractor Heembouw offices, they took the first steps for the design after which Pelecon was quickly brought in for the constructional issue. Especially the canopy at the front of the building, but also the heart of the office where the showroom is located, needed a solid structural foundation. Especially because of the limited building height, a compact construction was chosen for the building, with small spans and integrated steel beams.

Over the past 15 years, the brand has grown into a major player on the Dutch fashion market, which created the need for its own larger premises. The new building of Studio Anneloes consists of approximately 1,600 m² of office space, 2,000 m² of warehouse and approximately 600 m² of showroom. It is situated at a visible location along the S106 on a characteristic plot near the water and is designed in such a way that further growth is possible in the future.

Structural challenge
A challenge for the constructor were the large glass surfaces in the building, which ensure a lot of daylight and a beautiful view from the workplace. In the warehouse, large glass facades and a skylight in the roof provide daylight and views, creating a pleasant working environment for warehouse workers.

Structural calculations for sustainability
The company’s sustainability philosophy is also clearly visible on both the inside and outside of the building. For example, the facades have been constructed from a timber frame and clad with Neolife (92% wood and bio-based material and 100% recyclable). The construction of the warehouse roof has been calculated in such a way that it is possible to place sufficient PV panels on it to make the building completely energy-neutral. In short: the building is like a ‘tailor-made suit’ for the company’s activities.

Bouwtechnisch Adviesbureau Versteeg continues under Pelecon structural engineers

Geplaatst op: 31 March 2022

At Pelecon, we don’t hide the fact that we don’t sit still. For instance, a merger last year strengthened our services. We are hiring new engineers to meet the increasing demand and we are developing our knowledge. However, entrepreneurship also means making decisions that are not directly related to growth, but are logical for the focus of our company.

As from 1 April 2022 we will no longer offer services under the name Bouwtechnisch Adviesbureau Versteeg. The partnership between Versteeg and Pelecon was so intertwined that we took the logical step of no longer distinguishing between the two companies. And to continue together under the name Pelecon structural engineers.

Loyalty to each other
The structural engineers who worked for Versteeg are continuing their careers at Pelecon Gouda, so their knowledge will not be lost. We thank them and the clients of Versteeg for their trust and the positive reactions we received to this step.

Questions, introductions or just catching up?
Do you have any questions or would you just like a cup of coffee? Then please contact one of the partners of Pelecon. Henk van Vliet, André Verschoor and Mack Stolwijk can be reached at info@pelecon.nl, +31 (0)182 231 400 (Pelecon Gouda) or +31 (0)33 277 33 36 (Pelecon Amersfoort).

SEVEN HOUSES IN A ROW IN ZAANDAM

Geplaatst op: 24 March 2022

Customised rental and owner-occupied homes are being developed in Zaandam. We have received the buyers’ options for these houses and, as the main structural engineer, are currently incorporating them into the construction drawings. An extension, for example, has consequences for the basic drawings.

But these are not the challenges for us, the location of this new building project is. Archive documents show that a building used to stand here, the piles of which might still be in the ground. They are probably so deep that they were not found during an extensive soil survey. But that did not stop us from taking the possible old piles into account when calculating the piling plan. The new piles, if they were to be found, must not be too close to them. As a structural engineer, we remain involved during construction, so if an old pile is unexpectedly placed in an awkward spot, we can adjust our advice at that time.

The calculations and drawings for this project are now being finalised for submission to the Zaandam City Council.
