  2. General situation of the construction sector: First price & far after quality : short time view Black box calculations Modifications & adaptations Design & works period cuts Non quality Failures and damages Direct and indirect costs Subdivision of the works & lack of global approach Coordination & communication default Structures & codes complexity

  3. Origin of the damages

  4. Failure & damages : From watertightness to stability, across infrastructure or superstructure, soil conditions, phasing or structure assembly... Cost of the non-quality 10-15% of the global investment ! (Based on European studies)

  10. How to reduce failures and damages?How to manage these risks ? 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

  11. SECO • Founded in 1934by the sector as : • Cooperative association • Independent technical board • Independent third party • Recognized by the (Re) Insurance companies • Belgian leader also active in more than 20 countries • More than 3 billions EUR of current works supervised • Turnover : 22 millions EUR • 500 to 700 new projects per year (about 25.000 projects) • 200 persons (160 engineers)

  12. A preventive technical supervision Concept and design • Basic principles (soil and subsoil analysis, choice of foundations, stability...) • Tender documents • Detailed drawings • Parallel calculations performed by SECO Execution on site and in workshops • Regular visits • Critical phases Quality of the materials • Voluntary certification • Inspection in factories

  13. Reduction of technical risksSome examples Railway Station: Communication

  14. Reduction of technical risksSome examples Bridge: Calculations

  15. Reduction of technical risksSome examples Tunnel: Execution

  16. Reduction of technical risksSome examples Building: Design

  17. Reduction of technical risksSome examples Bridge: Design - joints

  18. Reduction of technical risksSome examples Tunnel Design Execution

  19. Reduction of technical risksSome examples Renovation

  20. Reduction of technical risksSome examples Buildings - Steel Structures

  21. Philosophy and methodology of SECO • Not compulsory in the Netherlands importance of a real adapted service:“Think and bring added value for the client; give confidence” • Financial & technical independence • Very high level specialists with large experience • Team work for each project • Risk analysis & quick Scan: critical points identification and strength on project weakness, prevent the repetition of similar errors • Efficiency based on internal knowledge analysisand large experience(Expert System, sharing of know-how) • “Problem solvers” spirit

  22. Our servicesTwo main sectors of activities Buildings • Main fabric • Shell and finishing works • Light facadesand external joinery • Timber and steel structures • Technical installations • Sustainable construction : support and assessment Valideo and Breeam Civil Engineering • Bridges and viaducts • Towers, chimneys, pylons • Tunnels • Roads and runways • Ports and quay walls • Water treatment plants and sewage networks • Landfills

  23. The Inherent Defects Insurance (10 years) Who • Constructors (Contractors & sub contractors), Architects, Consulting Engineers, Developers About • Buildings and Civil engineering works Cover • Structures (stability) & Majors parts (roofs, facades, ...)

  24. The Inherent Defects Insurance (10 years)implemented in the Netherlands • Cover  material damages to the works (structure & major parts) damages causes to third parties possible extension to finishing works & services • Collective insurance policy : no recourse against faulty parties • Linked to the works, not the insured parties (one premium) • Voluntary system (add value essential)
