Implementing lean construction and turning visions into reality

Upon completion of the contract award procedures, io-consultants takes you through the whole implementation phase up to acceptance and commissioning of the buildings and facilities and beyond.


With our project management experience and lean construction methods, we streamline and simplify the construction cycle for reliable and safe project implementation. We focus on keeping within the project schedules and budgets, and delivering cost certainty while simultaneously ensuring the agreed quality and services.
