TRADITIONAL OF PREFAB HOMES?

/in , , /by

Until now, when we asked ourselves whether we wanted traditional or prefab homes, the answer was always quick: we preferred traditional ones.

Traditional construction assures security, as the house is built with bricks and concrete; and offers variety of designs and durability over time. However, more and more families are discovering the advantages of prefabricated construction.

Prefab homes arise as a result of the evolution that architecture and engineering have undergone in recent years. This evolution resulted in the application of the highest technology to finishes, designs and construction materials, thus allowing the appearance of a wide variety of prefab homes: steel, wood, concrete… all of them with two characteristics in common: reduced costs and shorter construction time.

Prefab homes have many advantages. Among them we can highlight: construction time, which is reduced by half compared to traditional construction; use of high quality materials, that show high resistance to climate changes and meteorological phenomena; portability, being recoverable by more than 90%; safety, provided by the appropriate assembly technique; variety of designs, with more than a thousand finishes; minimum maintenance needed and, of course, reduced costs.

In Silicon Valley itself, where access to housing is difficult even for engineers from large companies like Amazon and Google, these companies have ordered 300 prefab homes for their employees, saving up to $700 a month.

Former employees of huge companies like Aaron Holm, who worked in product management for Amazon, or Michael Marks, one of Tesla’s first investors, have been quick to create startups dedicated to the manufacture and assembly of prefab homes. The business incubator Y Combinator, cradle of the successful Airbnb, Dropbox or Reddit, has also decided to invest in this future-oriented construction and has gone one step further: it has created a startup, Acre Desingns, which creates prefabricated and energy-efficient homes.

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 Security Guard Cabin at Ivory Coast | Prefabri Africa

/in /by

We carried out a new modular construction project in Ivory Cost. On this occasion we provided a prefabricated security guard cabin for a client at Abidjan.

Technical features: Prefabricated Security Guard Cabin Ivory Coast

Floor structure

The floor structure frame of the prefabricated security guard cabin is formed by galvanized sheet profiles shaped in cold. There are OMEGA galvanized steel straps placed transversally achieving major stability supporting vibrations and heavy load. This floor structure supports up to 250 kg/m2 uniformly distributed.

  • 18mm thickness special anti-humidity phenolic plyboard floor
  • Covering: sintasol Traviata 6026

Roof structure

The roof structure frame for this porta cabin is formed by longitudinal galvanized profiles and transversal straps conformed in cold. There are OMEGA galvanized steel straps placed transversally. These omegas support a trapezoidal sheet of 0.6mm thickness, screwed to the profiles through self-tapping screws with waterproof washers.

Columns

The columns are formed by galvanized sheet profiles shaped in cold. These columns are screwed to the floor and the roof of the porta cabin with special screws. There is a round PVC pipe with the diameter of 75mm serving as a gutter hidden in the interior of the column. A lacquered metal sheet in the interior of the module that fastens the electrical mechanisms, plugs, switches and electric protection panel covers the column.

Side walls

The lateral closure is composed of PUR 40mm thick insulating sandwich panels. Each panel consists of two lacquered galvanized steel sheets with a thermal and acoustic insulation layer in the middle formed by injected polyurethane self-extinguishing resins.

The panel is very resistant against humidity, staying unalterable over the years.

False ceiling

The false ceiling of the porta cabin is formed by galvanized and pre-lacquered metallic blades in white silicone polyester (0.5mm thickness). Fiberglass insulating material of 80mm thickness and vapour barrier is placed between the roof structure and the false ceiling.

The internal free height of this module is 2.275mm.

External carpentry

The external carpentry of the guard porta cabin is fabricated in white aluminium profiles.

The carpentry of this cabin is composed of:

  • Exterior door 975x2060mm with a handle and a lock
  • Glazed panel in white aluminium. Glass 3+3.
  • Sliding window 1800x1200mm.

Electrical installation

The electrical installation of the guard porta cabin 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 of low voltage. Electrical supply is connected to the electrical box with an independent protection via magneto-thermal switches and switches necessary for lighting, emergency devices (if necessary), air conditioning and other uses. The box is protected against the direct and indirect contacts, overcurrent or short circuit.

  • Waterproof lights with diffuser 2x36W
  • Plug entries 16A+TT
  • Surface switches of 10A+TT

In the standard prefabricated modules the electrical wiring is concealed behind the false ceiling and the tops of the columns, so the whole electrical installation is completely hidden.

Finishing

  • The whole structure of the guard cabin was painted in grey.
