Defect Liability Period including Operation & Maintenance cost for 4 years has been 0.5% of Civil Construction Cost per year. Price Escalation during construction period of 7 years has been taken.

5 SALIENT FEATURES OF TUNNELA km long Main Tunnel proposed on NH 1 to facilitate all weather connectivity between Srinagar and Leh. Length of Egress Tunnel is km. Western (Srinagar side) Portal : At Baltal (Km 95) Eastern (Leh side) Portal :At Minamarg (Km 117) Single tube two way tunnel with parallel egress tunnel. Three ventilation shafts, of which two shafts also to be used as construction shafts.

6 SALIENT FEATURES OF TUNNELSix working faces proposed. Estimated time for construction: Months Civil Construction Cost: Rs 5486 Crore Total Project Cost: Rs Crore Defect Liability Period: Years Operation & Maintenance Period: Years # Eastern portal face available for working round the year. # Work not possible at rest of the faces for about four months during the winter period.

15 Facilities & Safety FeaturesUninterruptible Power Supply (UPS) system Tunnel emergency lighting Emergency call system (ECS) CCTV monitoring  Variable message signs (VMS)  Traffic lights  Over height vehicle detection  Traffic logging equipment  Guidance system  Tunnel radio system  Internal telephone system  Sound system  Tunnel physical variables measurement system  Escape route lighting  Integrated tunnel control system- Supervisory Control and Data Acquisition (SCADA)

16 Function (SCADA SYSTEM)The ventilation shall be monitored and controlled in the Operating & Maintenance Centre (OMCs) via the Supervisory Control and Data Acquisition (SCADA) system. When the ventilation system function works in the normal mode of operation, the fresh air shall be introduced through the inlet portal and it shall push the engine emissions along the tunnel length up to the outlet portal or the exhaust shafts where the emissions shall be vented. The jet fans shall be fully reversible and may be activated from the tunnel control centre by means of the Programmable Logic Controller (PLC) in accordance with the functional protocols to be established. Each fan and jet fan shall be connected to the SCADA system via a PLC. The SCADA system shall be programmed to identify each cable for all of the fans. The SCADA system shall monitor the data received from all of the pollution measurement sensors. When the SCADA system detects values exceeding their defined limits, it shall then instruct the appropriate fan to switch on. A data cable from the fan motor shall be wired back to the SCADA system via the PLC and this shall inform the SCADA system about the current status of the fan (for example motor run status, motor speed, etc.) The fans can be switched on as required from the PLC to adjust the system performance to the particular necessities, i.e. light traffic hours, peak hours, emergency, etc.
