PREFABRICATED WORK CAMPS | PREFABRI AFRICA

/in , /by

Prefabri Africa is specialized in the design, manufacture and assembly of prefabricated work camps. We take part in construction, mining, oil & gas sectors. We also manufacture refugee camps.

We provide a complete service, which includes design, fabrication, transport and assembly of constructions at the place indicated by our clients.

We have available two modular construction systems based on client’s needs:

  • MODULAR CONSTRUCTION SYSTEM (CM)
  • FIXED MODULAR CONSTRUCTION SYSTEM (CMF)

Moreover, we have at our disposal high-standard products, made thanks to an European technology designed to withstand climatic conditions, cold, extreme heat and humidity.

PREFABRICATED WORK CAMPS: MODULAR CONSTRUCTION SYSTEM

Our modular construction system is based on fabrication and assembly of the free-standing prefabricated modules realized with a galvanized steel structure and insulating sandwich panels enclosing walls.

Those prefabricated modules can be used for independent spaces or for modular units via an assembly of different modules horizontally or vertically.

With this system there is no need to modify the foundations because the module is not fixed in the ground. Modules can be moved easily, that is why it is a perfect option for temporary or permanents camps.

Moreover, the CM system allows us to transport the modules in KIT (or Flat-Pack), which facilitates the on-site assembly, that can be done by untrained staff.

In addition to standard models, we manufacture made-to-measure modules with different dimensions, technical characteristics, interior layouts and equipment.

FIXED MODULAR CONSTRUCTION SYSTEM

We recommend choosing this system for projects such as permanent workspaces, which require a combination of specific spaces:  cafeterias, bedrooms, workshops and warehouses.

This system is based on metallic manufactured structures that are fixed to the slab previously made. The lateral enclosure is made with sandwich panels composed of steel sheet and polyurethane foam or Rockwool. The displacement to a new place requires the whole disassembly of the modules that is why this system is rather recommended for permanent camps.

Compared to  CM system, it provides a lot of advantages such as the versatility of the assembly, reduced costs, reduced transportation costs by delivering the materials disassembled but also  the possibility to get more opened-spaces, without pillars.

 

Security Portable Cabin for a photovoltaic power plant l Prefabri Africa

/in , /by

Prefabri Africa has carried out a new modular construction project applied to industrial solutions in Valencia. On this occasion, we installed two security portable cabins that will be used by the engineers of this photovoltaic plant to monitor the operation and production of the solar panels of the plant.

Our prefabricated solutions are ideal for this type of usages, given the advantages they offer with regard to traditional construction: logistical ease, quick installation of the structures, the minimal need of civil works and the modulation of spaces.

In this case, each of the security portable cabins is composed of a set of modules formed by two prefabricated diaphanous modules assembled. We used modules of 6,00×2,35m so the surface of each portable cabin goes up to 30m2. The security cabins are divided into two distinct areas: a working area for the engineers and a storage area for materials and control devices, which are connected by a sliding door. In the storage area, the floor structure has been reinforced to support a maximum load of 1200kg/m2 uniformly distributed. The modules were installed directly by Europa Prefabri with two technicians on site.

Technical specifications of the project: Security Portable Cabins for a photovoltaic power plant

Floor structure

The floor structure frame is formed by 2 vertical and 2 horizontal galvanized sheet profiles mm shaped in cold. There are OMEGA galvanized steel straps placed transversally achieving major stability supporting vibrations and heavy load. These straps support a water resistant phenolic plywood of 18mm thickness covered with grey PVC vinyl covering.

The floor structure described supports up to 250 kg/m2 uniformly distributed. We reinforced the floor structure in the storage area to a maximum load of 1200kg/m2.

Roof structure

The roof structure is formed by 2 vertical and 2 horizontal galvanized profiles shaped in cold. There are OMEGA galvanized steel straps placed transversally. These Omega steel straps support a trapezoidal galvanized metal sheet of 0.6mm thickness.

Columns

The columns are formed by asymmetric galvanized steel profiles shaped in cold of 2.00mm thickness. The columns are screwed to the floor structure and roof structure using special screws. There is a round PVC pipe with the diameter of 75mm serving as a gutter hidden in the interior of the column. The column is finished on its interior with a lacquered sheet that fastens the electrical mechanisms, plugs, switches and electric protection panel.

Side walls

The lateral closure is composed of sandwich panels, of 40 mm thickness. These sandwich panels are made of a two sided lacquered sheet on a galvanized base and count with intermediate thermal and acoustic isolation. In terms of fire resistance, this kind of panel has been classified as M2 material, which means it is highly fire resistant. It has been proven to be highly resistant to water, remaining unalterable over time.

False ceiling

The false ceiling is formed by galvanized and pre-lacquered metallic blades in white silicone polyester (0.5mm thickness). Between the false ceiling and the roof plate is placed an 80mm insulation fiberglass blade with vapour barriers.

The internal free height of these modules is 2.475 mm.

External and internal carpentry

The external and internal carpentry of the security portable cabins is manufactured in PVC or aluminium profiles lacquered in white.

The named carpentry consists of:

  • Exterior door 815x2060mm with a handle and a lock.
  • Interior sliding door 1200x2300mm with a handle.
  • White PVC 2 wing sliding window 815x1045mm.
  • White WC window 1 wing 815x500mm.
  • White PVC 2 wing sliding window

Electrical installation

The electrical installation system is complete except for the electrical line up to the location of the module. All the electrical system and installations are adapted to the safety requirements.

Electrical supply is connected to the electrical box with an independent protection via magneto-thermal switches and switches necessary for lighting, emergency devices (in case of having ones), air conditioning and other uses. The box is protected against the direct and indirect contacts, over current or short circuit:

  • Waterproof lights with diffuser 2x36W
  • Oval Outdoor Wall Light 60w
  • Plug entries 16A+TT (when placed in the bathrooms these are waterproof)
  • Surface switches of 10A+TT

In addition, we carried out the complete installation of voice and data supplies for the security portable cabins.

Manufacture and assembly of site office at Reims (North of France)| Prefabri Africa

/in , , /by

Prefabri Africa has carried out a new modular construction project in France. Last October we have finished the manufacture and assembly of three different site offices at Reims (North of France) for construction project purposes.

Technical features: Site offices at Reims

  • First tranch site offices: composed of 3 portable cabins of 6 x 2,40 m, one of them with a bathroom.
  • Second tranch site offices: composed of 5 portable cabins of 6 x 2,40 m, one of them with a restroom.
  • Third tranch site offices: composed of 15 portable cabins of 6 x 2,40 m, in two heights, with outside stairs. In this ensemble, there are 3 full restrooms.

For transport and logistics, we have manufactured 5 portable bathrooms for the site office completely finished and the other portable cabins have been manufactured and transported on KITS, for its assembly at the construction works.

As you will see in the pictures we attach, the structure is painted in the customer’s corporate colour.

The manufacture of the different site offices has been made with double panel in most of the modules to allow its individual use in the future or with different configurations. As permanent or temporal works infrastructure, portable cabins construction camps are the best option for easy assembly solutions.

The insulation of walls and windows can be adapted in thickness of material to adapt to any climate conditions or fire/sound proof applications in order to always offer the best solution and features to each project.

The spaces created with the different portable cabins and prefabricated modules can be easily adapted to the project needs: offices, dining halls, dressing rooms, bathrooms and sanitary facilities.


ADVANTAGES OF MODULAR CONSTRUCTION


Sustainability and recycling

Prefabri Africa is environmentally engaged, that is why our products are recyclable and can be dismantled. Industrialized construction allows a more efficient use of resources, by reducing toxic emissions and generating less waste.

Quality

construccion modular solucion constructiva para empresas europa prefabri

Industrialized construction in factory allows applying different quality controls in the production process, benefiting labour risk prevention by working on safer environments. On the other hand, it allows having a total control on the product manufacturing.

Customisation

Each customer is unique and has specific needs. The versatility of modular construction allows us to adapt our products to each customer, customizing the dimensions, distribution, materials and finishing of the constructions.

Insulation

We use innovative light materials that can have better levels of thermal and acoustic isolation and energy efficiency compared to traditional constructions.

A completely finished steel structure that consists of a floor-structure, a ceiling structure and pillars, each of them with its independent structural elements, compose prefabricated modules.

Dissembling and transportation

All modules can be easily transported, completely assembled in trucks, but also disassembled or in KIT (Flat-Pack system), which allows us to transport several modules in one truck or sea container, reducing transportation costs.

The design of our modules enables to assemble and disassemble them easily, even by personnel without any previous experience, thanks to the instructions and videos we provide.

PREFABRICATED LOCKER ROOMS

/in , /by

Here is one of our constructions realized last month. It deals with a modular building of locker room for workers installed in Madrid. Our client FCC trusted in us to complete successfully their project of construction. Modules have been installed on a metallic structure to optimize the use of the whole building space, to stock some tools. Indeed, the area available is really small. This project has been realized with standard prefabricated modules, but we added a “overcovering” with two slopes to secure the impermeability of the building and to increase the heating insulation. The degree of the inclination of the “overcovering” is due to the installation of the air conditioning equipments, those ones being protected by this “overcovering”. Other characteristic of this project: in the sanitary modules the standard floor (wood + vinyl tiled) has been replaced by a specific floor, made up of trapezoidal flooring, on which has been poured the concrete. The finishing touch : ceramic floor.
