Modular Building Explained

What is modular construction

Modular construction involves the assembly of complete buildings using individual modules, which are built in a factory. These steel-framed modules are manufactured to precise tolerances under controlled conditions, where construction is not disrupted by poor weather or challenging site conditions. The modules are fitted out with all electrics, plumbing, heating and internal finishes in the factory. Once completed, the modules are delivered to site by road, and simply craned into position. Modules are connected on site to create complete buildings of any size, including multiple storeys.

How are modular buildings assembled on site?

1. Individual factory-built modules are positioned by crane.


2. The required modules are added, side-by-side or end-to-end, to create the required floor area.


3. A single building is created. The interior layout can be designed to your precise specifications using partition walls, stairs and lifts.


4. Extra storeys can be added to create all the space you need.

Why choose modular buildings from Portakabin?

Modular construction is rapidly becoming the building method of choice for organisations that need assured-quality buildings completed quickly and on schedule, with minimal disruption to the environment or the local area. No other construction method can match the speed of delivery, minimal waste and disruption, and future flexibility of modular building. 

  • Modular construction is up to 50% faster than traditional site-based construction1
  • Factory-based construction minimises time spent on site – which means reduced noise and disruption, and a cleaner, safer construction site
  • Cost and time certainty – modular construction projects are not subject to weather-related delays or shortages of on-site skills. In fact, Portakabin has a track record of delivering 99.7% of building projects on time and on budget.2 That compares very favourably with the construction-industry average of just 45% completed on time and 63% on budget3
  • Assured quality standardsPortakabin has earned the ISO 9001 certification for its quality-management systems, which cover everything from office processes to manufacturing procedures. Portakabin buildings are manufactured in a factory accredited to ISO 14001 for its environmental-management systems
  • Future flexibility – it’s easy to expand, reduce, reconfigure or even relocate modular buildings to meet your changing needs

  • Minimal waste – by constructing your building off site, up to 90% less site waste is generated than on traditional construction sites4
  • Fewer defects – all Portakabin 
    buildings meet strict quality standards, and we operate a zero-tolerance policy towards defects
  • Fewer vehicle movements – there are up to 90% fewer vehicle movements to, from and on the construction site,5 minimising transport-related emissions and disruption

Modular construction video 
This time-lapse video shows the speed of modular construction. The building, which was constructed in Reading for Foster Wheeler, comprises 78 modules assembled over an eight-day period. The video clearly shows how large buildings are constructed using the Portakabin modular method. Foster Wheeler is a global engineering contractor and power equipment supplier.
