THE MANY ADVANTAGES OF TIMBER CONSTRUCTION

There’s a reason behind timber being used in almost all SMC2 constructions! There are many advantages to this increasingly sought after, noble and eco-responsible material. Today, timber is an essential building material which is found in all sectors. Brief focus on the timber construction trend and its advantages.

 

Timber construction is gaining momentum in France

Whereas just a few years ago timber construction was simply an alternative niche market for individual construction, today it’s the focus of attention.

 

The building sector generates about 25% of direct greenhouse gas emissions, which is why it’s important to look for solutions to guide construction towards less polluting approaches.

 

In France, there has been a sharp increase in the number of constructions using timber as the main material. The timber construction market share in the non-residential sector now exceeds 16%, with a steady year on year increase. And timber structure buildings, such as those we design for most of our projects, represent more than 75% of the market[1] in the professional customer sector.

 

Currently, the entire market has an excellent overall dynamic. The future of timber looks even brighter, as it will be featured in several international projects such as the 2024 Olympics in Paris. In March 2019, Julien Denormandie, the French Housing minister, announced that the Olympic Village buildings will be mainly timber constructions[2]. The organising committee made this choice because of the advantages of timber: ecology, ease of construction, durability, etc.

 

The advantages of timber constructions

SMC2 teams work with timber on a wide variety of projects for communities or businesses. One of the reasons timber is so sought-after regardless of the sector, is its eco-responsibility:

  • Its “manufacture” and processing require little energy;
  • It is durable, renewable and abundant: we prefer the most local sector possible because only 1/3 of annual European forest growth is used;
  • It plays an active role in limiting the negative effects of global warming because wood stores CO2: 1 cubic metre of constructed timber removes 0.9 tonnes of C02[3]from the atmosphere.

Timber also makes speedy building possible, in particular thanks to prefabrication and preparation phases in the workshop, which are ideal for achieving “weatherproofed” structures in shorter times. Timber also makes it possible to follow the RE 2020 recommendations on construction materials.

If we choose timber, it is also because of the comfort it brings in terms of thermal insulation: it is 12 times more insulating than concrete[4]! The result is substantial energy savings: it is estimated that timber can reduce heating consumption by 30% compared to concrete or brick constructions.

Furthermore, timber walls, frames and structures are very effective in regulating indoor humidity. Timber has the capacity to absorb excess moisture and evacuate it to the outside. It’s a powerful humidity regulator.

 

Timber, a material suitable for all construction projects

Moreover, timber offers great freedom in construction forms, it adapts perfectly to all our projects:

Sports and leisure:

  • Sports fields
  • Gymnasiums
  • Swimming pools
  • Paddle ball pitches
  • Indoor bowling facilities
  • Playgrounds

For the education sector:

  • Colleges
  • High Schools
  • Nurseries
  • Primary schools and kindergartens
  • Libraries

For the industrial and service sectors:

  • Offices
  • Goods storage buildings
  • Warehouses

Timber therefore has many advantages that can be used to create reliable and environmentally responsible buildings. By combining it with other materials such as textile membranes and metal, we can carry out any type of project. For more information, feel free to contact us.

BERLIN GETS A NEW HOT SPOT FOR BASKETBALL

A new center for Berlin street ballers has sprung up in Prenzlauer Berg: On June 21, the new basketball grounds in the Friedrich Ludwig Jahn Sports Park were opened. Highlight of the facility is the covered main court under an outdoor hall by SMC2, which can be used in wind and weather.

 

All in all, three “Full Court” basketball fields with six modern, height-adjustable basket facilities and high-quality rubber flooring were created on the layout of the Friedrich-Ludwig-Jahn-Sportpark. The main court is also covered and equipped with grandstands and floodlights. The project is an early construction phase of the planned extensive refurbishment and conversion measures for the traditional sports complex in the heart of Berlin.

Sports Senator Andreas Geisel opened the facility on Thursday, June 21, highlighting the cooperation with the youth department of ALBA BERLIN, which looks after the fields in the future. The fields are now an additional training opportunity for club sports but are mainly the residents and the basketball players from all over Berlin, the opportunity for guided or non-guided basketball games offer. In addition, there will be several streetball tournaments in the future.

The idea behind the project is to offer a freely accessible sports facility that can be used all year round and in all weather conditions, thus offering great potential for use. The outdoor hall above the main court fulfills exactly this objective: The structure consists of a glulam structure, is covered with a textile membrane and protects the pitch from rain and snow. At the same time, the textile membrane is translucent, so no artificial lighting is needed during the day and players can play in even, natural light. In addition, the membrane offers a high level of thermal and acoustic comfort and thus guarantees one thing above all: enjoy playing in any weather! In addition, the outdoor hall made of wood and membrane is a real eye-catcher, making the new facility in Prenzlauer Berg a real hot spot for basketball players.

[TESTIMONIAL] GERARD ALAZARD, MAYOR OF LUZECH (FRANCE)

“A two-in-one sports facility for Luzech”

 

For more than a year, the town of Luzech (46) and its 2,000 inhabitants have been enjoying a covered sports hall including a multi-sports surface and a tennis court. The town’s major Gérard Alazard talks about the completed project.

Why did you decide to build this sports facility?
Our previous secondary and primary schools, with a respective capacity of 250 and 200 pupils, were redesigned into a brand new school complex with a much larger admittance (700). To cater to these new requirements, we had to add a second sports facility to the existing gymnasium. Because we already had rugby changing rooms that were not being used during working hours on weekdays, the extra sports grounds were all that was missing.

Why did you choose the structure proposed by SMC2?
We are located in a historically classified area, right next to a 12th century tower. So we wanted an elegant structure that was neither massive nor imposing. In addition, the structure had to be lightweight because it was going to be built on floodable terrain.
Furthermore, the solution proposed by SMC2 is highly advantageous price-wise: a classic gymnasium would have cost about three times more. Operating costs are also much lower since the translucent fabric lets a lot of light through, making artificial lighting necessary in the evenings only. An added advantage is the fact that the facility doesn’t need to be heated.
And last but not least, the work was done fast, with earthworks beginning in November 2016 and the entire worksite completed in April 2017. The structure was assembled from late December to late March and was a genuine feat of engineering involving 24-metre long beams that had to be lifted into a hammed-in area with tricky access.

Could you introduce the building to us please?
With a floor area of 1,723 m2, the building is divided into two volumes, each featuring a different kind of sports floor. The first volume contains a multi-sports surface for handball, basketball (1 main court and 3 mini-courts running width-wise), volleyball (1 terrain main court and 3 courts width-wise), tennis and badminton (up to 7 courts). To fit all these uses, this volume has an all-purpose sports floor. The other part of the building houses a porous concrete tennis court to encourage this sports the whole year round, which isn’t the case with the existing outdoor courts. This second area also provides 4 additional badminton courts in case the timetables of the three physical education and sports teachers overlap.
This sports hall includes a lot of technical features like staggered facades, roof overhangs, relative humidity control, decorative artwork printed on frontages, etc.
In all, the structure is used 50 hours a week by the schools and about 30 hours by the sports clubs, i.e. nearly 12 hours a day. After almost a year in operation, we are highly satisfied and have had a lot of very positive feedback from regular users and visiting players alike.

[TESTIMONIAL] JEAN-LOUIS REYNAUD, MAYOR OF PRESSINS (FRANCE, 38)

We wanted an airy covered structure for a wide range of activities.

 

In early July, Pressins (38), a town of 1,160 inhabitants, inaugurated its school’s outdoor gym. The town opted for the Preosport® solution and is now enjoying a sports facility that can host a wide selection of activities.

 

How did the project begin?
Our school, which has more than 160 pupils, didn’t have a gym area suitable for children’s activities, including sports. So we made the most of our 700 m2 plot of land adjacent to the school to build a covered structure. The aim was also to supplement our sports facilities: a tennis court, a football field and a bowling pitch.

 

Why did you choose the solution from SMC2?
The Preosport® is an airy structure that’s covered and designed to be a fully-fledged outdoor gym for use the whole year round. We also liked the fabric membrane that lets a lot of light through. In addition, it was easy to build a customised facility: its dimensions are 22 x 70 m with a height of 5.50 m under the roof. It includes several marking layouts, football goal cages, school equipment and a height-adjustable net for tennis, badminton and volleyball. As for the floor, we chose a coated aggregate solution.
It’s a structure that features a lot of highly technical solutions. For instance, it has a discreet single sloped roof to drain off rainwater from the single roof pitch located alongside an existing drainage ditch. So we didn’t need to install a special drainage system. It’s also a structure that’s ideal for multi-activities, which seamlessly matched our needs and intentions. Lastly, it was also an economic choice since the cost is significantly lower than a traditional gymnasium.

 

How is this facility being used?
It is mainly used for school and extracurricular activities, but also by the town’s associations, both sporting and others. For example, the outdoor gym is used for the school fete, jumble sale and some group meals with up to 150 guests. The gym is freely available the rest of the time. In addition, because the structure is independent from the schoolyard, we also hire it out for private events, especially evening events, as it has a manually-adjustable lighting system. Since it was inaugurated, the feedback is very positive so we’re satisfied with this investment, especially since the structure is easy to manage and requires no special maintenance.

[TESTIMONIAL] “THIS CLOSED BUT AIRY STRUCTURE IS AN EXCELLENT COMPROMISE”

In December 2016, Gagnac sur Garonne (31), a town of some 3,000 inhabitants, inaugurated ASTRIA, a Preosport housing a multisports area and a bowls pitch. Patrick Bergougnoux, the municipal councillor in charge of finance and project prime contractor, talks about this investment meeting a number of requirements.

 

How did the project begin?
Because the town did not have a gym, we had been intending to build a covered facility for many years to supplement the two outdoor tennis courts, two football fields, bowls pitch and the association halls (gym, dancing, music, etc.) we did have. We had a plot of land available nearby the existing structures, but it was in a flood-risk zone. After a lot of thought, we decided to invest in a Preosport from SMC2 because it demanded fewer building permit constraints than a gymnasium.

 

What was behind this choice?
It is an excellent compromise because it’s a roofed structure with closed sides that let the air in because they feature slats along the lower sections and micro-perforated fabric along the upper sections. Having a roofed facility was important to be able to host school and club activities, in particular for children. In addition, this system avoids having to pay high operating costs since there is no heating and very little lighting thanks to the structure featuring translucent tensile fabric that lets in natural light. Lastly, it blends into the environment perfectly, an important criterion for a rural town like ours.

 

Could you tell us about this sports facility?
The first section features a 45 x 36 m structure housing two multisport areas separated by a moveable net, for football, tennis, basketball, badminton and volleyball. When it’s not subdivided, the area measures 40 x 20 m and can therefore host handball and futsal matches. So, the French Football Federation has accredited this field at futsal level 3 and the two lengthwise areas (34 x 17 m) at futsal level 4. This dual playing area can host several sports activities simultaneously, which is highly appreciable because the facility is used very intensively by the two nearby schools and the Gagnac Sports and Culture Association (more than 1,600 members in all).
The second section, located further along, measures 36 x 10 m and houses a bowls pitch. It can accommodate up to 4 games for an official competition and a few more for training and friendly games.

 

What feedback have you had so far?
Feedback has been very positive since this investment has empowered the existing football, tennis and French bowls associations to continue play even in bad weather conditions. Furthermore, this facility has fostered the creation of a badminton club and is expected to provide incentive for leisure activities involving basketball or volleyball. As far as operation goes, the facility is run like a gymnasium: it is reserved to municipal and club activities with free access not currently contemplated.

[TESTIMONIAL] CHAVENAY GETS A TWO-IN-ONE SPORTS FACILITY

The town of Chavenay in the Yvelines department has built indoor tennis courts plus a judo and dance hall. Completed about a year ago, this sports facility is giving a new lease of life to the town’s sporting life, according to Siegfried Jahn, deputy mayor in charge of works.

 

What made you build this sports facility?
The existing sports hall was the former girls’ school: so it goes without saying that the design wasn’t right and it was very cramped. Moreover, we had no covered tennis courts, which meant a lot of members were pulling out to join clubs in the surrounding towns. The club’s membership dropped from 200 to fewer than 150 in a short lapse of time. So we obviously needed to fix the problem. And we were right to do so because our tennis club’s membership has since risen above the 200 mark. In addition, we were able to host the Gally Tournament very successfully.

 

How did you make your choice regarding the structure?
We had to respond to several constraints because we are in a historical village. So, we had to work with the architects from Bâtiments de France. For instance, we weren’t allowed to put up a bubble structure over the tennis courts like many other towns have done. We then started finding out about the other solutions available to us. We got interested in SMC2’s portfolio and roofing system, especially from the architectural design viewpoint. This was an important criterion for us. We needed a facility that met all these constraints and one that would blend seamlessly into our environment. We are entirely satisfied with our choice and I would like to commend the efficient team work that went on with the company’s technicians in addition to its professionalism.

 

Could you tell us about the facility?
Both courts (45 x 40 m) are roofed by a wood frame with large side windows. The roof features a translucent covering provided by a tensile fabric membrane and a roof frame with 100% wood cladding. The facility is very bright and is not heated, but merely tempered at 12 °C. Because of our geographical location, heating would be pointless with respect to the investment involved. This solution easily provides for use the whole year round except perhaps for a fortnight over the year in the event of extreme cold or hot weather. Both courts are lit with LED floodlight arrays. One of the courts is marked for handball (with a fold-away goalpost system) for school children.
We also have a small complex featuring a 100 m2sports hall, changing rooms, washrooms and reception. The hall is divided into two for judo and dancing. It is mainly used by the town’s multisports club as well as its schools and the outdoor leisure centre.
This structure responds to a whole series of requirements and revitalises our town’s sporting life in addition to enhancing its attractiveness.

CONSTRUCTION OF A COVERED FOOTBALL PITCH FOR GÖTTINGEN UNIVERSITY (GERMANY)

CONSTRUCTION OF A COVERED FOOTBALL PITCH FOR GÖTTINGEN UNIVERSITY (GERMANY)

 

In 2016, SMC2 built a 2132 sqm covered football pitch for Göttingen University in Germany. The University Sport Department wanted a covered area for football playing which would be accessible all year round and whatever the weather would be.

 

The University priority was to make an aesthetic building and its main structural requirements were a wooden frame and a translucent cover, that is why the University was seduced by SMC2 technical skills and commercial offer.

 

Thanks to SMC2 expertise, the building process was quite fast for such a complex structure which perfectly respects technical and aesthetic requirements. In spite of its dimensions, this covered football pitch fits perfectly in its immediate environment and makes other German universities envious of it.

PREOSPORT®: THE OUTDOOR GYM

Faced with a real lack of sport and leisure facilities, with matters made worse by schools’ new schedules, their favour of extracurricular activities, and a shortage of available land, SMC2 developed a new indoor sports and recreation area solution that can be used to revamp an existing sports centre or develop a new site.

This concept is attracting the attention of more and more local communities. Nord, a French department in the north, is proof of this: it recently chose to start a development programme based on the concept by offering subsidies to cover sports facilities.

PREOSPORT® has many strengths: not only does it enable people of all ages to enjoy athletic activities year-round, this multipurpose indoor sports facility also has the advantages of being environmentally-friendly and economical.

A true “outdoor gym”, this solution is based on an innovative construction principle that offers many advantages:

  • Moderate investment and low upkeep costs
  • Turnkey solution, quick to implement
  • Long-lasting infrastructure: 30+ year lifespan / fabric cover guaranteed for 17 years

Sports for all

A true outdoor gym, the PREOSPORT® makes sport accessible to everyone, year-round, all while providing optimally comfortable playing conditions for all its users: natural lighting and real acoustic comfort (no echoing). Plus, its fabric cover provides protection from the elements in summer and winter. This allows athletes to take part in their sports in an open air environment regardless of the weather outside.

Developing sports facilities on a budget

Thanks to construction methods that favour dry processes and eco-materials, the PREOSPORT® is within communities’ reach, involving only a moderate investment. As it requires very little upkeep, it can become a true means for development for areas that suffer from a lack of sports facilities. For the price of a single traditional gym, 10 PREOSPORT® facilities could be built. This covered sports and recreation area can be used to revamp an existing sports centre or develop a new site.

 

PreoSport®: The Outdoor Gymnasium by SMC2

Ecologically-friendly and sustainable

Composed of a glued laminated timber roof structure with a fabric membrane, the PREOSPORT® boasts a lifespan of over 30 years and is 100% recyclable. Thanks to its eco-construction processes, installation has a minimal environmental impact.

 

 

SCHOOL PLAYGROUNDS: THE ADVANTAGES OF TEXTILE

The school playground combines many uses within a kindergarten, a primary school, a secondary school or even a high school. It provides shelter for pupils, offers shelter in bad weather and hot weather, and provides a space for recreation and games. For its installation, there are different solutions, such as the composite membrane. What are the advantages of textile architecture for this type of project?

TEXTILE ARCHITECTURE: MULTIPLE DESIGN POSSIBILITIES

Just like a textile façade, a schoolyard equipped with a composite membrane enhances the architecture of your buildings. It can be adapted to various styles and constraints in order to fit into different environments. In compliance with NV 65 and CTS safety standards, textile architecture takes into account all the design aspects of your project:

  • The load-bearing capacity of the materials and their adjustable tensile strength: tensile strength, thickness ;
  • The dimensions of the school playground: height and surface area depending on the school, as well as the number of classes and pupils it accommodates;
  • The possibility of integrating several adjacent or independent structures;
  • Customisation options: colour of the composite fabric, appearance of the posts, etc.
  • The school canopies can be self-supporting or leaning against the facades of the buildings.

THE SCHOOL PLAYGROUND: AN ESSENTIAL SHELTER FOR OUTDOOR ACTIVITIES

The school playground remains a privileged place to gather pupils, organise events and allow children to have fun. It is a transitional space between the school and the playground and provides permanent shelter from the elements and the harshness of the season. The composite fabric can be of varying degrees of translucency, providing natural light for optimum comfort.

The composite membrane, which acts as the fabric, also has a low thermal inertia. This means that there is no heat transfer. This prevents the temperature under the covered area from rising. In addition, it provides valuable shade from UV rays and glare on sunny days in summer. This is essential to ensure the safety of the children and to prevent any alarming symptoms, such as sunstroke.

THE COMPOSITE MEMBRANE FOR A SCHOOL PLAYGROUND: AN ECONOMICAL AND DURABLE STRUCTURE

SMC2’s know-how is applied to many innovative architectural creations, such as modular wooden constructions dedicated to the education sector or multi-sports halls. Whatever the structure concerned, it is important to take into account the management and operating costs of the assets. This is also true for school playgrounds in textile architecture. They require only the simplest of occasional maintenance, in particular through the application of an anti-fouling varnish.

A textile fabric is perfectly waterproof and is protected against UV rays, dirt, natural ageing and atmospheric pollutants. This ensures its longevity and durability for many years. In addition, the cost of building a school playground with a composite membrane is less expensive than structures with “classic” materials. Its lifespan is equivalent or even superior. SMC2 creations are guaranteed for 25 to 30 years, making them a long-lasting investment.

ANCHOR EACH SCHOOL PLAYGROUND CONSTRUCTION PROJECT IN AN ECO-RESPONSIBLE STRATEGY

With SMC2, choosing a school playground with composite fabric also means benefiting from a sustainable development policy. The metal-textile structures respect eco-responsible criteria in order to reduce the environmental impact at the time of installation, then during occupation and use of the premises. Each material used is subject to rigorous selection. Wood, metal and composite fabric are designed to be fully recyclable at the end of their life cycle. During the construction process, you save energy and the building is ready for use more quickly.

[TESTIMONIAL] JEAN-PHILIPPE RECAMENTO, PRESIDENT OF THE TENNIS CLUB AMICALE COURVILLOISE (FRANCE)

« A structure that fits perfectly into the landscape »

 

SMC2 has just built a covered structure for two tennis courts in Courville-sur-Eure (France). Blending in perfectly with the surrounding listed monuments, it allows the club to take its development to a new level. We spoke to Jean-Philippe Récamento, president of the tennis club, who initiated the project.

 

Why did you want to cover two courts?

Until now, we only had two outdoor porous concrete courts and a few slots in two gymnasiums to practice during the winter. These conditions were insufficient to offer year-round activities to our 110 members. So, to create a new dynamic within the club, it was decided with the town hall to cover the two existing courts (while renovating them) and to build two additional outdoor courts.

 

What was the main problem with the project?

The site is located near several listed buildings (Saint-Pierre Church, Porte Saint-Nicolas, etc.), so it had to accommodate a facility that would fit in perfectly with its surroundings and meet the requirements of the Architectes des Bâtiments de France. The company SMC2 was chosen for this project and was able to adapt perfectly by proposing a structure that met the desired criteria. The white textile roofing membrane allows a maximum amount of light to pass through. It is guaranteed for 22 years and does not require any particular maintenance. On the façade, the membrane is brown in order to blend in with the park next door. In addition, the sub-base of the building is 4 m high in order to be in line with the clubhouse and thus obtain a harmonious whole. Inside, the structure has a wooden frame with a single line of intermediate posts.

 

Can you present the building?

The building consists of a 140 m2 zinc clubhouse with changing rooms, storage rooms, an office and a living area. Afterwards, the sportsmen and women have direct access to the sports area, which consists of two courts with a needle-punched membrane and a very fine ceramic sand filling. Both courts are lit by about 30 LED spotlights each. However, so far we haven’t had to use the lighting much, except from 5.30 or 6 pm, because the textile membrane allows a maximum of light to pass through, without it being a nuisance for the sportsmen, with no shadow areas. It’s very pleasant, while allowing us to save energy.

 

What is the first feedback from users?

The members are very satisfied because the playing conditions are optimal. Since they were inaugurated in September, the indoor courts have been very busy: about 40 hours a week for training, a dozen hours at weekends for competitions, not counting the slots reserved for leisure activities… With these new facilities, the club has already increased the number of members to 140 and our objective is to reach 250 in the near future.
