Abstract:

Infrastructural projects under a Design, Build, Finance and Maintenance contract (DBFM) need a different approach for information management.

This paper gives an insight of Dutch initiatives in the HSL ZUID project (High speed rail track from Amsterdam to Antwerp). This contract is awarded is 2001 and delivered as a DBFM contract in 2007. Today the track is in operation and the maintenance contract started. One of the challenges is the stability of the rail track in relation to the soft soil in this part of The Netherlands. Tunnels and bridges are creating fixed points in the substructure of the rail track and the soil in between these fixed points is soft. An important issue for the operation of this rail track is the possible damage of the track caused by whether bad design and construction or by the different movements in the substructure. Glass fiber sensor systems are used to monitor deviations at the points where the fixed substructure transfers to soft soil. Some examples will show the relation between contract requirement, needed data and the use of sensors. The aim of the research is to show that monitoring the performance of a structure is conditionally for the execution of a DBFMO contract.

The following questions will be addressed: What are the contract requirements? How has the system been designed to show and approve that the supplier meets these requirements? Which data are needed in this quality system? How can new technology support the secure monitoring of the desired data? How can monitoring of the performance create the condition for DBFMO contracts?
