6 OPP KLIPLEV SØNDERBORG KMG was the first and might be the only OPP Motorway project in Denmark Only functional basis requirements have been given (e.g. IRI, or location of bridges) Bank guarantee 40 Mio. Euro over 26 years Tender costs of approx. 4% of the project costs Contractors are ask to develop their own solutions they also trust Contractors has to handle new risks, e.g. Ground risk, utilities, neighbours, traffic

7 FACTS ABOUT THE PROJECT 26 km of 4-lane motorway between the E45 at Kliplev and the Alssund Bridge at Sønderborg 7 intersections 18 km of minor roads to be modified

8 FACTS 2 years for Design & Construction 26 years Operation & Maintenance 2,90 Mio. m³ Earthworks (mass balance) 0,35 Mio. m³ soft soil 0,90 Mio. m³ Lime Stabilisation to CL90 0,90 Mio. m² Cement Stabilisation to 0,80 Mio. m² Asphalt m dewatering pipes m slot drain (in-situ)

9 TECHNICAL PARAMETERS Cross section Homogeneous cross fall 30 Overall width 29.50m Green middle strip (2m) as a water tight construction 35 cm thick layer of compacted clay with mineral additives. Pavement Design 2.5 cm bitumen-concrete SMA 6+ (with noise reducing surface) Compact Asphalt 4 cm bituminous binding course ABB 11 8 cm bituminous bearing course GAB cm cement stabilized sand layer 40.5 cm compacted sand layer BL II xx cm lime stabilisation (incl. subsoil grade)

10 CROSS SECTION GENERATION ONE

11 LESSONS LEARNED - KMG Innovative pavement and reduced LCC Lime Stabilisation gives a basis to optimize the pavement design CS layers are an solution, cracks must be considered MMOPP vs. CS Inconstant pavement design Emergency Lane Compact asphalt and Slot Drain are an plus point

12 Kliplev Sønderborg Motorvejen

13 PAVEMENT DESIGN NEXT GENERATION We need, compare to CS, more flexibility to increase lifetime (20+) and avoid cracking Less and hydrophobic cement Use of Geogrids between GAB and AAB Semiflexible Pavements (AGRAC) Cement bundet asfaltgranulat-lag 85% (efter vægt) asfalt granulat 0/40 mm 15% sand og bliver, for at opfylde de styrkekrav 3,0% cement (type CEM III / B 42,5) og 6% vand MPa (mindst 2000 MPa trykstyrke efter 7 dage) Minimum 12,5 cm Asphalt Fordele: Halvstiv belægningsdesign Genbrug af asfaltgranulat Optimeret belægningsdesign og forlænget levetid Mindre revne- og spordannelsesrisiko MMOPP must be adjusted Simplify pavement construction

17 Concrete Roundabout

18 TOTALENTERPRISE IN DENMARK Since 2010 used for projects >100 Mio. DKK VD New Banedanmark projects > 200 Mio. DKK 60% Price 40% Technic & Management Paradigm change in VD, but projects which are tendered out at the moment are regarding design ready for TBL High influence of Designers Innovations are seen as a critic to their chosen Base-Solution Ask to optimize the LCC, but no freedom to do it 1% of Construction Costs for Tendering

19 TOTALENTERPRISE POSITIV EXAMPLE In case the Contractor intends to use solutions which are unconventional in relation to common Danish practice, the Contractor shall provide documentation that the solution fully complies with the basic requirements In addition, the contractor shall as a minimum provide information about lifecycle costs, maintenance and references to similar European structures in service.

20 TOTALENTERPRISE NEGATIV EXAMPLE

21 TOTALENTERPRISE WISH LIST Contractors need the freedom to develop innovative, but LCC orientated solutions A maintenance guarantee period of 10 years would promote that Evaluation must be done with an transparent tool, and not consultant driven We need a deeper understanding in the industry of new pavement forms (CS, KAS, KAB). E.g. with MMOPP you can design a MV with 8cm Asphalt Optimized pavements also need homogenised subsoil conditions
