We work with several partners more often, Jan Snel – Daiwa House being a good example. Since they started a separate business as a unit builder, our cooperation has only intensified.  In which their own products and services went through a major improvement. Nowadays, we no longer talk about units, but about modular construction, because modular construction is much more well thought-out and innovative than the units we know from the past. By designing a building in fixed module sizes, offices, flats, or houses can be built through unit construction or element construction. We would be happy to tell you more about it.

From Pelecon, Bastiaan Hoefnagel works a lot together with Jan Snel – Daiwa House. We are happy to ask him about the cooperation. Bastiaan explains that Jan Snel, Daiwa and Medexs are three separate companies under the DaiwaModularHousing Group (DHME), all three working within a specific market. Their products are particularly interesting for small-scale flat construction, offices, operating rooms (Medexs) and serial housing construction. Jan Snel (JS) provides the market with temporary buildings, earthquake-resistant housing in Groningen, temporary classrooms, or migrant centres. DHME focuses more on large-scale projects such as student housing. DHME is also one of the companies chosen by the government to build housing quickly. This was also in the news last month,” Bastiaan said.

A history together
Bastiaan continues: “We have been working together for at least 20 years, with JS/DHME’s various modular construction systems serving the market ever more professionally. Modular construction is a specialisation that has developed further in recent years. Many disciplines come together, with production, (manufacturability), seriality and remountability always being the most important spearheads. We have grown along with JS/DHME to become one of the specialists among modular construction”.

Pelecon’s added value for Jan Snel – DH
Speed of our service and service are very important to JS/DHME. Bastiaan explains that in the design process, JS/DHME has often already made many choices. “Our job is to calculate the building as much as possible within the DHME standard, should it not be constructively possible the impact should be as minimal as possible. Choices and principles made are determined based on previous projects carried out. In which the foundation is almost always the major variable. JS/DHME’s modular building systems have a low deadweight compared to traditional construction. Due to the lightweight structural construction and often non-permanent housing, a foundation on ‘steel’ is often desirable. Foundations can also be installed in some situations in the form of concrete slabs on a sand bed. In this way, the entire building can be removed completely at the end of its use and placed elsewhere. Applying a remountable foundation on ‘steel’ is not possible in all the Netherlands. Therefore, a pile foundation is insurmountable in some cases.”

Pelecon wants to make a difference
“The building systems developed by Jan Snel may or may not have been developed together with our engineering firm. Pelecon’s input always concerns structural safety, but manufacturability and remountability are also a starting point. JS/DHME’s various modular construction systems have advantages and disadvantages, where building designs in modules and remountability are always the main starting points. Currently, an HBO student is working on graduation research on high-rise buildings with JS/DHME’s building systems. DHME’s strength is that they can build modularly, which meets the strictest standards and are always reusable after use. Sustainability at its best!”

The future
Bastiaan is proud that the ambitions of both Pelecon and Jan Snel – Daiwa House are boundless! “New factories have recently been built in Montfoort and Bunnik for which we also provided the structural consultancy. DHME wants to become the largest modular builder in Europe, Pelecon is happy to contribute its stone to this as a structural consultant!”

On our website and socials, we write quite a lot about our projects, developments within Pelecon, but also about the structural engineering profession in general. By doing so, we want to emphasise not only our passion, but also the importance of the structural engineering profession.

Because only when an idea is turned into a concrete plan do feasibility, sustainability and practicability become important factors. The skeleton of the building, the structure, then literally supports the design. That reality makes a building structural engineer’s expertise literally vital. #theinvisiblepower

Because we like to talk about our invisible force and because we like to stay in touch with the people within our field, we have a fun win campaign. Are you our 1,000th follower on LinkedIn? Then we have a nice surprise for you!

OUR PARTNER (ALSO CLIENT FOR THIS PROJECT) DAIWA HOUSE WAS COMMISSIONED BY DUTCH MULTINATIONAL Mammoet TO CREATE A CANTEEN AND SHOP. PELECON IS THE STRUCTURAL ENGINEER FOR THIS PROJECT, WHICH IS CHALLENGING DUE TO THE COMBINATION OF TRADITIONAL AND ELEMENTARY CONSTRUCTION. THE TRADITIONAL PART CONSISTS OF A TABLE STRUCTURE ON THE GROUND FLOOR, WHICH FORMS THE ROOF FOR THE CAR PARK, THEREBY TAKING UP MINIMAL SPACE ON THE PLOT. ON TOP OF THIS TABLE CONSTRUCTION, THERE WILL BE TWO FLOORS OF UNIT CONSTRUCTION CONSISTING OF MOVIX FLOORS.

Not only the combination of traditional and unit construction and the table construction, but also the footbridge is a challenge of this project. This footbridge will soon connect the existing building (De Bolder) with the new building. Our task was to make the calculations for the entire building and to draw the traditional part. Here, we determined the profiling of the table structure and the Movix units, specified the stability provisions and calculated the foundations.

STRUCTURAL CHALLENGES FOR PELECON
The movix system will be placed on the table structure. By using reinforced concrete columns, we were able to make this structure “puddle” fire-resistant without additional cladding. Parking is possible under the table, and the columns also had to be calculated for impact loads. Another challenge was that the exact dimensions and position of the walkway are not yet known. This can only be measured once the new building is in place. Finally, we are dealing here with the diabolo shape of the De Bolder building. That means it is round, but also falls in at an angle at the connection.

Structural engineers Bastiaan and Evelijn are satisfied with the result of our advice and will also stay on top of this assignment during realisation for any reconsiderations. After all, our work does not end when the drawings and calculations are handed over.

WE RECENTLY CALCULATED AND DREW FOR A COMPLETELY NEW STOREY FLOOR IN AN EXISTING DISTRIBUTION HALL OF ROYAL A-WARE. THIS CHANGES THE FUNCTION OF THE HALL FROM STORAGE AND TRANSHIPMENT HALL TO A PRODUCTION LOCATION. AN ASSIGNMENT WITH PLENTY OF CONSTRUCTIONAL CHALLENGES FOR PELECON!

These challenges mainly involved determining the column and pile positions within the grid of the existing building. In this type of building, production is always leading for the layout. A real puzzle at times. The new piles are screw injection piles, installed in the limited height. Directly on these piles rest the new story floors with sufficient bearing capacity for machinery and transport.

Today we posted the first of a series on our LinkedIn page about our clear promise “The invisible force”. For us, this is a given for every project we work on. #theinvisiblepower

The road from dream to reality runs through challenges, tasks and decisions. Along the way, thins are fine, tunes, reconsidered and adjusted where necessary. Since the creative mind sets the direction, limitations are avoided. And always the starting points is an initiative. An idea.

When designing a building, it is no different. Only once the idea is turned into a concrete plan do feasibility, sustainability and practicability become important factors. The skeleton of the building, the structure, then literally supports the design. That reality makes the expertise of a building structural engineer literally vital.

Pelecon is a specialist in converting designs into concrete and feasible constructions. Almost fifty years of experience enable us to convert an initial design into reality as sharply as possible. This is mostly about technology, but we are aware that it is even more about personal contact. By working closely together and communicating directly with clients, architects and implementers, the best ideas come to life. But whatever the collaboration looks like, Pelecon watches over the safety of all building users. Carefree.

Refrigerated and frozen logistics; a Pelecon speciality

Geplaatst op: 19 January 2023

FOR OUR CLIENT BIEZE FOOD GROUP, WE WERE ALLOWED TO ADVISE ON YET ANOTHER PHASE 3 OF THE EXPANSION OF THEIR REFRIGERATION AND FREEZER LOGISTICS IN NIJKERK. AN ASSIGNMENT WHERE WE CAN PUT OUR SPECIALIST KNOWLEDGE TO FULL USE, AS THE CONSTRUCTION FOR A FREEZER HALL IS SPECIAL.

The floor of a cold store is always constructed as a double floor, with heating in the lower foundation to prevent freezing through. This is followed by a thick layer of insulation and a top floor on which heavy racking can be placed. This latter floor shrinks as soon as the freezing machines (condensers) are switched on. At -25 degrees, the floor shortens by as much as several centimeters.

SPECIALISM
Pelecon specializes in refrigerated and frozen logistics. The Bieze Food Group is a loyal customer of Pelecon who likes to make use of this specialist knowledge. Once completed, their optimally developed logistics hotspot enables them to safely store, process and then transport their food in chilled condition.

For this assignment, we worked together with van Bokhorst Architects and contractor Dijkham Bouw; both from Nijkerk.

Challenging project in Middelburg

Geplaatst op: 17 January 2023

ON THE SITE OF THE FORMER SPORTS COMPLEX ON THE NASSAULAAN IN MIDDELBURG, THE OFFICIAL PILE WAS STRUCK ON THURSDAY 24 NOVEMBER FOR THE 33 NEW FLATS IN THE VEERSEPOORT 5 PROJECT. TOGETHER WITH THE BUYERS AND INVITED GUESTS, MR. J. LOUWS, DISTRICT COUNCILLOR OF VEERSEPOORT AND DEPUTY MAYOR OF THE MUNICIPALITY OF MIDDELBURG, HERALDED THE START OF CONSTRUCTION OF A TOTAL OF 108 FLATS. PELECON IS INVOLVED IN THIS PROJECT AS MAIN STRUCTURAL ENGINEER. IN WHICH WE ARE RESPONSIBLE FOR CALCULATING AND MODELLING THE THREE APARTMENT BUILDINGS AND EIGHT BLOCKS OF GROUND-LEVEL HOMES.

Veersepoort 5 is a new-build project of Stevast Baas & Groen B.V. of Capelle aan den IJssel, our client for this project with whom we worked closely. Also, to the challenges that came our way during the project. Pelecon structural engineer Elise Booms says: “The biggest challenge for the ground-level homes was actually mainly in the floors. For a large part of the blocks, at a point in the development process, a different floor type was chosen for the floors (first it was hollow-core slab floors, then it became wide slab floors), with the argument that concrete lintels above the door recesses were not desirable. With wide slab floors, this can be solved in the floor itself, by applying reinforced strips. This led, among other things, to more foundation piles in connection with applying these heavier floors. Once worked out, buyers’ options were added, too, whose final changes we are currently working on.”

THE HOMES OF VEERSEPOORT 5
The homes have a great diversity in size, layout, and price, making Veersepoort 5 attractive to different target groups. In addition, the City Villas and flats are ideally suited as homes that can be used for life. All ground-level houses in the plan are energy-neutral and all flats are almost energy-neutral. The first houses and flats are expected to be completed in early 2024. Construction of Veersepoort 5 will be carried out by Dura Vermeer Bouw Zuid BV from ‘s-Hertogenbosch.

New Dicoon laboratory in Elst

Geplaatst op: 21 December 2022

IN ELST, A MODERN LABORATORY IS BEING BUILT, WHICH BEARS THE NAME DICOON (DIAGNOSTIEK COMBINATIE OOST-NEDERLAND) AND IS CONNECTED TO THE RIJNSTATE HOSPITAL. THIS IS A UNIQUE AND CHALLENGING PROJECT IN WHICH PELECON IS INVOLVED FROM A TO Z IN THE DEVELOPMENT OF THIS LABORATORY FOR CENTRAL AND SOUTHERN GELDERLAND FROM AND FOR HEALTHCARE PROVIDERS. TOGETHER WITH OUR PARTNERS, WE ARE BUILDING A HIGH-END BUILDING; JAN SNEL IS CONSTRUCTING THE SHELL, WHILE SISTER COMPANY MEDEXS, A SPECIALIST IN THE COMPLETION OF BUILDINGS FOR MEDICAL PURPOSES, IS TAKING CARE OF THE FINISHING TOUCHES.

The request for help to Pelecon was clear: do you want to make a structural design for the superstructure of the building, the stability provisions, and the substructure? Medexs established the framework together with the column positions, we then investigated the possibilities that fall within the Movix system. The Movix system consists of loose floor and roof elements; these elements are placed and stacked on site.

Colleague Evelijn explains, “the building is composed of Movix floors and roofs. Normally, these units have standard dimensions of 6 meters by 3 meters and 7.5 meters by 2.5 meters. For this project, a span of 9 meters by 3 meters had to be created in several places; a modification that is not standard. In addition, we could not install wind bracing everywhere (which is normally the case with the Movix system) due to the desire for free partitioning. Instead, we used the stairwells as stability provisions by placing the wind bracing here. This meant that the floor really had to act as a sheave; we also determined the additional provisions for this.”

The small projects deserve just as much attention

Geplaatst op: 21 November 2022

IT’S NOT ALWAYS THE BIG PROJECTS THAT IMPRESS, BUT THE SIMPLICITY OF THE SMALL PROJECTS ALL THE MORE. THIS IS ESPECIALLY TRUE OF THE HOUSE IN NIJKERKERVEEN FOR WHICH PELECON WAS ENGAGED AS STRUCTURAL ENGINEER BY LEGEMAAT DESIGNERS FROM VEENENDAAL. WE HAD TO ENSURE THAT THE BEAUTIFUL, UNIQUE DESIGN COULD ALSO BE REALIZED STRUCTURALLY. AND WE SUCCEEDED!

The main challenge in this design was to keep the design as simple as possible, with many possibilities for the future. We succeeded by using steel trusses. The basement had the great advantage that we could go straight to the load-bearing layer as a foundation.

But what could be more fun for us as structural engineers than an uncommon question? The search for solutions inspires and challenges us to go that extra mile. Ultimately it is very cool to see that the creative design can be implemented thanks to our constructive solutions.
