Building of the Litschberg Basic tunnel and the Szekszrd Danube bridge

Report ID: 76

In the summer of 2002, the Swiss Federal Audit Office (SFAO) celebrated the 125th anniversary of its founding. Friendships among the invited foreign guests were strengthened and there was a resolve to
continue the successful cooperation. An agreement was made with Hungary to organise a parallel audit
on investments in the area of transport infrastructure and to focus on the following topics:

• The Szekszárd bridge construction investment within the context of motorway investments in Hungary
• Tunnel construction investments within the context of the New Rail Link through the Alps (NRLA).

Apart from reinforcing and intensifying relations, the joint activities are intended to contribute to enhancing the specialist knowledge of both audit authorities.

In order for this approach to take place, delegations visited Hungary in the summer of 2003 and visited Switzerland in the spring of 2005. The revised work is now published in a joint report which will be released by both audit authorities within the scope of EUROSAI and EU activities.

Joint Report on Parallel Audits of Expenditure on the Construction of the Motorway Prague – Dresden

Report ID: 276

In 2005 and 2006, the two supreme audit institutions of Germany and the Czech Republic conducted parallel audits of expenditure on the construction of the motorway Prague – Dresden (D 8 motorway in the Czech Republic and the A 17 motorway in the Federal Republic of Germany).

The motorways are connected by a border bridge co-financed by the two countries. By working together SAI Germany was able to audit in depth the efficiency of the funds used for building the border bridge. As a result of working closely SAI Czech Republic  was furnished for comparative purposes with the necessary data of German cost levels of bridges and tunnels.

As part of the joint audit effort motorway bridges on the D 8 and A 17 were compared based on the prices per square metre of area of the bridge structure. The statistical analysis of prices made it possible to identify bridges that came at a high cost per square metre. This analysis revealed that the border bridge was the most expensive bridge as compared to other large bridges having a length of over 100 metres. The price increase could also be attributed to the delays occurred in the tender procedure.

When auditors analysed the costs of tunnel structures they found that the prices of tunnels are considerably higher on the D 8 motorway than the prices of comparable tunnels in Germany.

Benefits
The cooperation achieved the objectives of both audit institutions. The two supreme audit institutions developed a database of the prices of bridges and tunnels that can be relied on in future audits.
