    Mumbai water project record advance: TBM logistics and design notes for engineers

    Mumbai water project record advance: TBM logistics and design notes for engineers

    First reported on Tunnels & Tunnelling International – News

    30 Second Briefing

    Terratec’s T83B open TBM on the Mumbai water tunnel project achieved 752m advance in July 2025, claimed as a national record for a water tunnel drive using a single rail track and two mining locomotives. The cutterhead configuration, integrated ground support systems and operational flexibility have matched the alignment’s geology, sustaining high penetration and consistent progress. Productivity gains also stem from tightly planned logistics and cross‑shift co‑ordination, backed by Terratec field service engineers embedded with the contractor’s tunnelling team.

    Technical Brief

    • Single rail track haulage with only two mining locomotives constrains mucking capacity and material logistics.
    • Integrated ground support systems on the TBM reduce separate drilling/bolting cycles, shortening each advance round.
    • Embedded Terratec field service engineers enable on-the-fly optimisation of cutterhead use and support sequences.
    • Public acknowledgement by project leadership signals formal performance tracking and benchmarking against national tunnelling records.
    • Similar single-track water transfer tunnels could adopt comparable open TBM plus rail logistics where geology permits.

    Our Take

    Terratec appears only sporadically in our Infrastructure coverage compared with larger global TBM suppliers, so a 752 m/month advance in Mumbai is likely to be used as a key reference case in its bids for other high-capacity urban water and metro tunnels.

    Among the 158 Infrastructure stories in our database, very few urban water projects report this kind of single‑month excavation length, suggesting Mumbai’s geology, logistics and segment design have been optimised aggressively for advance rate rather than staged risk reduction.

    With completion targeted for early 2025, this performance benchmark in Mumbai could influence procurement criteria for upcoming Indian urban tunnelling packages, where clients may push contractors and OEMs to demonstrate similar advance rates without compromising lining quality or settlement control.

    DSIT’s CNI cybersecurity drive: design and monitoring lessons for engineers

    The Department for Science, Innovation and Technology has expanded its Cyber Runway Critical National Infrastructure programme with innovation accelerator Plexal to bring more cybersecurity SMEs into protecting UK energy, transport, water and digital networks. The scheme targets operational technology and industrial control systems used in assets such as substations, treatment works and tunnels, where legacy SCADA and remote monitoring are increasingly exposed to cyber-physical attacks. For civil and infrastructure engineers, this signals closer integration of cyber risk into asset design, condition monitoring and resilience planning.

    Gatwick PAS 2080 certification: whole-life carbon lessons for project teams

    London Gatwick has become the first airport globally to achieve PAS 2080:2023 certification for carbon management across its buildings and infrastructure assets. The BSI-verified standard requires quantified whole-life carbon baselines, option appraisal and reduction pathways for capital works, including terminals, piers, pavements and associated civil engineering. For designers and contractors working at Gatwick, future schemes will need to evidence embodied and operational carbon performance alongside cost, influencing material choices, construction methods and asset renewal strategies.

    Northern Ireland DfI AI road stock-take: asset management lessons for engineers

    Northern Ireland’s Department for Infrastructure has commissioned mapping specialist Gaist to deliver a network-wide digital stock-take of its road assets using AI-based condition assessment. High-resolution imaging and machine-learning classification will be used to catalogue carriageway defects, drainage features and street furniture, creating a georeferenced inventory to support maintenance planning amid a mounting roads backlog. For asset managers and pavement engineers, the move signals a shift towards data-driven prioritisation of resurfacing, patching and drainage interventions across the regional network.
