1 Basics

Initial conditions Budgetary deficits for construction, maintenance and operation for streets Dramatic deterioration of the conditions of streets and constructions High economic defeats caused by a reduction of the fixed asset, road traffic noise immission, inadequate road safety, congestions and longer ways extensive reduction of administration structures caused by budget reductions

1 Basics

First steps PPP – acceleration law / 08.09.2005 Coalition agreement: Stimulating of private capital within traffic way construction Introduction of lorry toll since 1.1.2005 Realisation of 4 (5) A- models Realisation of F- models Utilization of functional construction agreements Maintenance model / Thuringia for rural streets

3 Maintenance model in Thruringia

Example Maintenance model for state roads inside the Saale-Holzland-area

Pilot project for ca. 20 km Construction – Maintenance – Operation 30 years contract Guaranteed money for 30 years Functional announcement

3 Maintenance model in Thruringia

aimed to demand - renewal, maintenance and operation of a selected communal road network Functional announcement for construction, maintenance and operation Projectfinancing (private own capital) and forfaitation as elements for financing recompense linked to a fullfillment a special road network condition Availability linked with a bonus-malus system

• bligation inside the state budget

volume more than 100 Mio. € for 30 years gradually transfer within the rural road network road administration only responsable for origin administration tasks

3 Maintenance model in Thruringia

• Possibility of financing
• Task description

(functional)

• Life cycle view

(advantages in productivity)

• Distribution of risks
• repayment guided through achievement (Bonus/Malus, availability)
• Functioning market

(competition)

• Projectvolume

(compensation costs for transaction)

3 Maintenance model in Thruringia

Operation works guarantee for a continuing lightness and fluidity of traffic

Objective

Level of demand is to fulfill in all parts of work

structural maintenance Plant service service and maintenance of equipment cleaning winter maintenace further works e.g. road control Responsibility in the full time of 30 years

4 Foundations of searching for a road network

Existing structures (classes of streets, existing local operation units Representation of street conditions – stand and development Further optimization of life cycle (construction, maintenance – unit over 30 years) Definition of maintenance strategys Classification of operation works for PPP Adjusting with existing structures of local street authorities Possibilities of financing

4 Foundations of searching for a net

Development of a maintenance strategy

Objective Objective

Determination of the required maintenance demand on basis of the estimated road level for quality and expected condition development Determination for short-dated measures Determination transferable maintenance demands under consideration of financial devices Realization of a maintenance program attributed to the network with long maintenance time intervals and with a view to a great benefit by an improvement of the substance of roads

Quality assessment of surface conditions, pavement conditions and other road network facilitieste

Objective Objective

Assessment of road surface conditions

• Condition sizes
• Condition values
• separated value for

use and substance

• Complete value

Condition sizes are converted in condition values Weighting and assessment of separated values

5 Example for a PPP-solution for communal streets

View

Private sector works economically then the public maintenance and construction units. The lifecycle view brings over a certain time a high economically effect. The key for more PPP-utilizations goes over the political side and not over the public street authorities. There are given many possibilities for PPP-solutions in road infrastructure, but every single solution can be different from the other and demands other investigations.
