January 2021: The Municipal Corporation of Greater Mumbai (MCGM) extended the road network of the city with a belt road seaside, already partly realized with the Bandra-Worli Sea-Link bridge, crossing the Mahim bay. This new route, the Mumbai Coastal Road, is 30 km long and mostly on bridges and is closed at its south end by an approx. 4 km long tunnel. This links the Worli interchange to the Marine Drive, also known for its arched shape called the Princess Necklace, towards Nariman Point near the renowned monument of the Gateway of India.
The design of the tunnel was awarded to Lombardi Group by Larsen & Toubro, the company selected for its realization and the largest contractor in India.
After 1 year of design and the completion of the preliminary works, the largest hydroshield TBM in India was lowered in the launching shaft (becoming part of the future ramp to the surface portion of the project) last December. The TBM "Mavala" was activated this January 2021, the 11th day, under the auspices and presence of the state Head Minister of Maharashtra, whose capital city is Mumbai. The TBM is manufactured by China Railway Construction Heavy Industry Co. Ltd. (CRCHI) according to the design specification Lombardi defined and calibrated in cooperation with the contractor and the manufacturer.
The TBM has the largest diameter today in India (12.19 m), allows the installation of precast segments of 35 cm thickness according to the named "universal geometry". On its invert, a precast utility box harbours all canals, technical ducts and the cabling for the ventilation, the lighting, the detection and the tunnel management.
Lombardi Group presence in the project is assured by its Indian branch, the headquarters in Switzerland and the contribution of its Italian branch. It developed the civil work design of the tunnel and the related works (the cross passages and the technical buildings) and the design of the ventilation system, the safety equipment and the electromechanical equipment, as well as the complete SCADA system (Supervisory Control And Data Acquisition) for the operation management and control as well as in case of accident or of maintenance. Fire accidents with 100 MW fire power (heavy truck with high fire potential, according to the Rijkswaterstaat curve) have been simulated by 3D CFD (Computational Fluid Dynamics) analyses in order to define the efficiency and the characteristics of the ventilation system (Saccardo system).

|47||Validated risk assessment tool LoRis 2.0 in accordance to the Swiss guideline ASTRA 89005|
June 2019: It is in all our interest to reduce the risk and provide a high level of safety to tunnel users. Swiss guidelines ASTRA 19004 and 89005 define a quantitative assessment methodology that describes the role of risk analysis in decision making and the evaluation of measures to achieve a higher safety in tunnels of the national roadway system. This methodology has been implemented in LoRis, an internally developed tool that facilitates the investigation of risk and provides information about cost-effective measures for existing as well as new tunnels.
LoRis is built on a Bayesian network, a probabilistic model, that computes the individual risk and relevant FN curves for fatalities and injuries. The underlying scientific approach takes quantitative information regarding events, and processes consequences using mathematical functions and CFD-simulations. The methodology is applicable to tunnels with a length greater than 300 m, open to the transit of normal, heavy goods and dangerous goods vehicles.
The tool is in continuous development, following the statistical trend of base rates, ready to employ the newest principles and perspectives of the roadway research community.
