Rome-Naples high-speed rail route

WORK DETAILS.

ASACERT – QUALITALIA on behalf of the IRICAV UNO Consortium carried out the in-progress Technical Control service on the works of the 1st Functional Lot of the Rome-Naples High-Speed railway section. The Rome-Naples High-Speed line is part of Railway Axis No. 1 of the Trans-European Conventional Railway Network and allows high-speed trains to pass through the section between the capital and the capital of Campania. The scope of the Technical Control service includes the civil works subject to static testing related to the Rome-Naples High-Speed section, which is a total of 200 km long, also including the works already completed (minor works and finishes completed by the “substantial deadline” of 31/08/2005). The works subject to inspection are divided into different macro-types:

• Bridges and viaducts
• Natural galleries
• Artificial tunnels
• Railroad riders, underpasses and interference
• Technology buildings.

SERVICE

ASACERT – QUALITALIA carried out the in-process Technical Control service on civil works subject to static testing pertaining to the 1st Functional Lot of the Rome-Naples High-Speed railway section. The total amount of work was €2,300,000,000. The service consisted of several inspection phases that the ASACERT – QUALITALIA team carried out with its usual professionalism thanks to the presence of qualified technicians and experts in the specific fields of interest.

• Phase 1 – Audit at the IRICAV UNO Consortium.
• Phase 2 – On-site audit: acquisition of IRICAV UNO Consortium QS documentation (QM and Procedures).
• Phase 3-Processing of significant samples: the works constituting the total of the 1st Functional Lot are 1,059 including 106 natural and artificial tunnels, 113 viaducts, 233 road and rail interferences, 41 buildings, 308 embankments, 39 interferences with subsystems and 219 trenches. Following analysis by the working group, a sample of 243 works were selected to undergo static testing for an amount exceeding €1,000,000:
  • • 94 natural and artificial tunnels
    • 145 viaducts and overpasses
    • 4 manufactured.
  Among them, the following 25 works subject to static inspection exceeding €10,000,000 have assumed essential importance:
  • • 14 natural and artificial tunnels
    • 11 viaducts.
  The remaining part of the sample consists of the secondary works identified from the information available and updated following the conduct of the audits to sample about 300 works, or 30 percent of the total.
• Phase 4 – On-site monitoring on sample works: this phase was carried out according to a predefined schedule with the client through inspections carried out along the railway line. A corresponding site inspection report was prepared for each work inspected.
• Step 5 – Verification of design drawings: this step was carried out on a sample of construction drawings chosen from those kept in the site archives. The sample was chosen taking into consideration the main types of works present. The corresponding design analysis report was produced for each typological construction project.
• Step 6 – Review of completed structure reports and static acceptance certificates issued: the corresponding document analysis report on the completed structure report and acceptance certificates was produced for each work.

RESULT

In-depth documentary analysis was carried out at the construction site, where access was gained to all documentation produced during the execution of the works and where any nonconformities found could be analyzed. At the end of the in-process Technical Control service carried out by ASACERT – QUALITALIA, it was possible to issue a positive judgment based on the results of the verification audits carried out.
