Technical Control Bureau for Construction
General situation of the construction sector:
Non qualityFailures and damages
Direct and indirect costs
Design & works period cuts
Modifications & adaptations
Black box calculations
Subdivision of the works & lack of global
approach Structures & codes complexity
Coordination & communication default
First price & far after quality : short time view
Technical Control Bureau for Construction
Failure & damages :
From watertightness to stability, across infrastructure or superstructure, soil conditions, phasing or structure assembly...
Cost of the non-quality10-15% of the global investment !
(Based on European studies)

The sector • The builders, public and private owners (Engineers, Architects, Contractors) are looking for more confidence (an insurance)
The insurance • Requirement of a second opinion.
Aim Reduce failures and damages by a global prevention action
Design, calculations
Execution, materials
