Technical requirements: Request for Proposals to act as Technical Advisor to HRADF to compile “Risk Analysis without the involvement of Vehicles Carrying Dangerous Goods” for the tunnels of Egnatia Motorway
HRADF is seeking to engage a specialised and highly experienced technical adviser who fully understands the technical and operational issues of road tunnels in Greece, and of the Motorway in particular, in order to provide its services on compiling the necessary "Risk Analysis without the involvement of Vehicles carrying Dangerous Goods" reports for sixteen (16) tunnels of Egnatia Motorway as shown in Table 1 hereof (the “Advisor”).
The objective of the present contract is the successful completion of the commissioning of the particular tunnels by the Tunnel Administrative Authority (DAS), therefore the "Risk Analysis without the involvement of Vehicles carrying Dangerous Goods" individual studies and they shall be deemed to have been properly delivered by the Advisor only upon the unqualified (i.e., without further comments) and reserved acceptance thereof by the Tunnel Administrative Authority (DAS).
The Risk Analysis studies should be compiled according to the guidelines issued by the Tunnel Administrative Authority - DAS (version 2011), "Risk Analysis Methodology of road tunnels without the involvement of vehicles transporting dangerous goods – Scenario based approach". The risk analysis studies should be compiled by the use of appropriate software for:
A. Risk Analysis Studies by using three-dimensional (3D) CFD simulations and B. Risk Analysis Studies by one-dimensional (1D) simulations.
The Risk Analysis Studies must include the modeling of fire with HRR = 100MW with the characteristics defined in Scenario 7 of the above-mentioned guidelines issued by Tunnel Administrative Authority (DAS), as follows:
Involvement in the fire of a heavy truck (average value) → HRR peak 100MW with the following characteristic values: tmax = 300sec, tD = 3.900sec and td = 5.100sec.
Data regarding the construction, the characteristics, and the equipment of the tunnels as well as the traffic and wind data will be provided if, where and to the extent that they are available.
For each tunnel, the Risk Analysis will be submitted in the form and structure required by the relevant issue (version 2011), "Risk Analysis Methodology of road tunnels without the involvement of vehicles transporting dangerous goods – Scenario based approach" of the Tunneling Administrative Authority (DAS). The Analyses will be submitted in printed and digital form in both English and Greek and will be accompanied by the digital files of the simulations and results for the software that will be used.
Tunnels that will be studied using three-dimensional (3D) CFD simulations are the following: S2 Mesovouniou, S3 Grikas, S1 Selianis, Votonosiou, Anthochoriou, Dio Korifon, S1 (Asomaton),  S10 Vermiou, and S12 Polymylou.
For these tunnels, multiple consecutive 3D CFD simulation scenarios will be considered to determine the required combination of hazard mitigation measures in order to ensure safe evacuation.
The selection of the measures that will be examined and proposed as a result of the Analyses shall be made with the aim of minimizing their costs and implementation time, as well as avoiding increased budget measures that would require a longer period of study and installation (e.g. complete mechanical ventilation systems, sprinkler systems, shorter distance between emergency exits, etc).
The Adviser shall prepare and include in the studies to be compiled a preliminary cost estimate for all the measures proposed, analysing the materials and installation works, either at market prices or at Public Works prices per individual tunnel analysed and studied.
Tunnels that will be studied using one-dimensional (1D) simulations are the following: Vasilikou, S11 Polymylou, S1Ν Αg. Nikolaou, Dodonis, Krimnou, Kalamion and S13 Polymylou.
These tunnels are equipped with mechanical ventilation systems and based on previous analyzes and simulations may be authorised without requiring additional construction measures. For the specific tunnels based on the results of the Analysis, potential targeted operational measures will be proposed. The Adviser shall prepare and include in the studies to be compiled a preliminary cost estimate for all the measures proposed, analysing the materials and installation works, either at market prices or at Public Works prices per individual tunnel analysed and studied.
