Benefits of Karanttia prefabricated element and modular solutions

Prefabrication has been proven to enhance the productivity and time management of construction projects. Unexpected and unforeseen additional costs or site delays in construction are eliminated. Fully completed assemblies for construction sites are quick and bring substantial schedule savings. In prefabrication, industrial construction approaches are put to practice away from the construction site, which means that subassemblies for the building project can be made full-time in pace with the construction works progress, regardless of weather and season. For the duration of the design stage, Karanttia’s design team is at the customer’s disposal. The design team consists of an architect, HVAC and electrical designers, and a structural designer.
