50 percent reduced speed due to flaws in the construction of Ahmedabad Metro

Safety regulator seeks third party audit of Ahmedabad Metro operations

In August and September 2022, the Commissioner of Metro Rail Safety-CMRS inspected the railway work of 40 kms of Metro Rail. In which many flaws have come to the fore. This directly affects the safety of the passengers. The Gujarat Metro Rail Corporation (GMRC) has been asked to plug the loopholes. Metro Rail has not considered them serious even after major flaws have come to the fore. Many defects have been found in the pier, station and construction. Which is dangerous for 7 lakh passengers.

The structure of a ghat near Thaltej had collapsed. There were two such incidents.

A report has been prepared by Gujarat Metro Rail Corporation identifying various types of defects in the Ahmedabad Metro. In which Sabarmati railway station, underground tunnel, Kankaria station, cracks in the piers and defects in construction, trestle piers, doors have come to the fore. Questions have arisen on the security of the Gandhidham Railway of the Railway Department. Therefore, the speed of the Ahmedabad Metro with a speed of 80 kmph has been reduced to 45 kmph. Indian Express reports.

who is responsible?

Now, questions are being raised on the working of companies like Nippon Signal Company, URC, Kumar Infraprojects, DRA-CICO JV, Afcons Infrastructure, Larsen & Toubro, Tata Projects, CRCC JV, Simplex Infrastructure, Ranjit Buildcon, Ranjit JV, Simplex Infrastructure, Tata Huh.

PM Modi

Prime Minister Narendra Modi will inaugurate the first phase of 40 km of Ahmedabad-Gandhinagar Metro Rail on 30 September 2022. However, the Metro Railway Safety Commissioner (CMRS) has asked for third party audit – 90 other conditions are being fulfilled. In addition – the structural strength and quality of tunnel sections and viaducts and elevated section piers are said to be certified.

The PM will inaugurate the remaining 13.3 kms of the first phase connecting Thaltej and Vastral on the East-West Corridor and 18.83 kms on the APMC-Motera Highway which is part of the North-South Corridor. The 6.5 kilometer rail is running for 4 years. The Gujarat government on Saturday announced that both the routes would be opened to the public two days after the inauguration on the occasion of Gandhi Jayanti.

Track cost

The 39.26 km long Ahmedabad Metro Phase 1 project consists of two lines and 32 stations. An expenditure of Rs 10,773 crore was fixed. Now that cost has become about 14 thousand crores.

The cost of metro rail in 2003 was Rs 3500 crore. The cost has increased manifold because of Modi’s incompetence.

32 stations

The 20.73 km Line-1 (East-West or Blue Line) connects Vastral village and Thaltej village with 17 stations in between. It has an underground section of 6.5 km with four underground stations. The 18.87 km Line 2 (North–South Corridor or APMC Red Line from Vasna to Motera) has 15 stations.

Several technical flaws have been found in both these lines.

More than 7 lakh passengers at risk

Since there has been a delay of 10 years, the cost has increased by Rs 2 to 5 thousand crores. If the 40-km Phase-I was completed on time, the Metro would have started operations in 2018. 4.50 lakh passengers will travel annually in 2018 and 6.50 lakh in 2021. Today 7 lakh passengers will travel in 2022. There are 10 times as many people under train tracks. In this way 17 lakh people can be at risk. Every day 2 thousand people are going to sit in the metro.

Underground dangerous

The CMRS also demanded a technical audit of the tunnel ventilation system in the underground section of the metro. He points to “shortcomings”, such as the lack of protection against possible train derailments in flying sections on railway lines. During the mock drill, concerns were expressed about the time taken by the Metro to evacuate the passengers.

Speed is halved

GMRC replied on 14-15 September 2022 that the issues have been resolved. The project is safe for operation. However, conditional authorization was given in the authorization letter issued to GMRC earlier this week for the inauguration of the Ahmedabad Metro. In some sections, the speed has been asked to be kept up to 45 kmph. The maximum speed of metro rail is 80 kmph.

Railway line danger

A metro track has been built on the Indian Railways between Ahmedabad and Bhavnagar. As stated in the CMRS letter, the North-South Corridor passes through sensitive areas adjacent to Indian Railway lines. No special protection is provided for this. The derailment of the railway line below threatens the safety of the metro poles. No action has been taken to remove it.

Improper design

The speed limit between Paldi and Old High Court building stations has been kept at 60 kmph instead of 90. The metro was properly designed to be safe on the railway track after a risk analysis was done by the NITs or IITs. Necessary security measures should have been taken for this. There should have been a security wall. Priority has to be given to the safety of metro trains.

Cracks in pillars

The CMRS in the report stated that, during the inspection of the North-South corridor, it noticed deficiencies. There are cracks in the pillars and culverts. Measures need to be taken for long term stability and security. IITs were advised to conduct third party audits within three months to check structural strength, quality of viaducts and piers. Indian Express reports.

In the tunnel no communication network

There is no mobile network coverage inside tunnels and underground stations. There should be continuous communication of trains within the tunnel. But this is not the case in Ahmedabad.

Steel girders bad

Validate the design and quality of work is essential. Third party audit was requested for steel girders. Span steel girders are non-standard. It has been used at many places on the metro route. Some bolts were found to be loose and cut and broken.

Reduce speed

The security body has not evaluated the quality of the Sabarmati Open Web Girder Bridge. Remove the shortcomings of the metro and get it certified with rights within a month. Till then, the metro has been asked to run at a speed of 60 kmph on the bridges passing over the tracks of the Indian Railways. Indian Express reports.

Sabarmati station was not investigated

Sabarmati metro station was not put up for inspection. It required separate approval before it could be opened for public use. CMRS has asked for permanent closure of the station. Trains have been instructed to leave the station. Sabarmati station is an important station as it connects passengers of Metro, Railway, BITS and Bullet trains here.

Kankaria station left without investigation

Like the Sabarmati station, the underground Kankaria East station was not allowed to be inspected. Trains have been asked not to stop at both these stations.

Old signal

Platform screen doors of metro stations have been damaged. To certify the quality of the systems. Some signaling equipment is an old wreck. Its manufacturing date is 2018. This is not acceptable in new metro works. The signal has been asked to be changed immediately.

Cracks in the tunnel

There are cracks in the tunnels of the East-West Corridor. There are traces of leakage in the underground section. There is lack of cracks, reinforcements, castings, piers, bridges and Sabarmati bridge.

River bridge fault

A speed limit of 60 kmph has been asked on the Sabarmati Bridge. There are errors in six spans and other cases. Told to fix it in a month. Third party audit was done by RITES for structural safety.

Check the tunnel

Tunnel ventilation system for underground section will have to be improved. An upgrade is needed. A technical audit of the tunnel’s ventilation system and fire safety clearance was sought from the fire department. CMRS also advised third party quality audit to verify the structural strength and quality of Viaduct, Pierce and Tunnel segments over a period of three months.

Inclined pillar

CMRS inspected this corridor between Apparel Park and Thaltej station on 20-22 August and 4 September. The section of 6.5 km from Vastral village to Garment Park is already operational. During the inspection, they found a pillar bent at Commerce Six Road. Therefore, it is said to maintain the speed of 45 kmph on the Thaltej road. Recommended measures and third party audits to check pillar safety and certification.

Elevator failure

The faulty lift has been repaired and the PSD has been asked to repair the doors. Branded water coolers were asked to be installed. Groundwork for Ahmedabad Metro – for which DPR was prepared from 2005 onwards. After seven years of construction, the first phase of the project is said to start commercial operations later.

Question from Rathore

Gujarat Metro Rail is a joint venture between the Government of Gujarat and the Government of India. Its Managing Director SS Rathore believes that this project has been completed with the conditions. But he was not ready to discuss matters related to the security of the Metro. Rathod believes that a third party audit has been called for to re-evaluate the safety and structural quality of the elevated and metro rail, which had earlier sought this for 6.5 km.

Metro Phase-1 was targeted to be completed by January 2020. But due to delay in operations, the target was pushed ahead.

Construction company dispute

The IL&FS company, which was trapped in the scam of Rs 1300 crore, was again entrusted with the responsibility of the metro rail project of Ahmedabad. As the project was revived after 8 months, the smell of rampant corruption remained. Which has been proved to be true by this report. In 2018, the central government was struggling with a bank loan of 91 thousand crores on IL&FS.

The company is embroiled in liquidation disputes, financial irregularities and irregularities.

The contract worth Rs 382 crore was re-awarded to Gujarat Metro Rail Corporation and Engineering and Construction Company Limited.
