Why modular

Factory precision. Site speed.

A modular building is made in a factory while its site is prepared, so the two run at the same time instead of one after the other.

IDEC designs modular and prefabricated buildings for module manufacturers, pre-engineered building suppliers and main contractors, from concept to shop drawings and as-built records. Our projects include NEOM, KAFD in Riyadh, Amaala and Jeddah.

  • Workforce accommodation
  • Residential communities
  • Offices and site facilities
  • Container buildings
  1. 01

    Faster to deliver

    Factory and site work run in parallel. Studies report projects delivered 20 to 50% faster than conventional construction.

  2. 02

    Built under factory control

    Members are cut by CNC machines straight from the model and checked at each stage, away from wind, dust and rain.

  3. 03

    Less waste, lighter foundations

    Off-site methods can cut construction waste by up to 90%. Light steel modules weigh about 30% of masonry, so foundations are smaller.

  4. 04

    Can be moved and reused

    Steel modules are bolted together, so they can be taken apart and set up again on a new site.

From foundation to fit-out

How a module is built

Layer by layer from the foundation to the roof, then the design and model behind it, and the finished building.
