National Highways has started procuring one of the world’s largest tunnel-boring machines for the Lower Thames Crossing, as the project’s forecast cost rises to £11bn for the new road tunnel beneath the Thames Estuary. The TBM will be sized for twin-bore highway tunnels carrying dual carriageway traffic, demanding large-diameter excavation, high face pressures and complex segmental lining logistics in soft estuarine ground. Contractors and designers will need to manage settlement control, water ingress risk and spoil handling at a scale comparable with only a handful of global road tunnel schemes.

Mott MacDonald has been appointed by Iarnród Éireann to lead Ireland’s national Connect rail programme, a multi-corridor upgrade of intercity routes linking Dublin with key regional cities. The commission covers programme management, systems integration and multidisciplinary design for track, structures, stations and digital signalling across the existing heavy rail network. For civil and geotechnical teams, the role points to upcoming packages involving corridor capacity works, bridge and formation upgrades, and staged construction on live lines under Irish and EU interoperability standards.

A new survey of UK rail sector leaders reports a sharp fall in confidence, with 64% of respondents expecting market contraction and most suppliers either freezing recruitment or cutting staff. Contractors and consultants cite delayed enhancements, uncertainty around Control Period 7 workbanks and paused major schemes such as HS2 phases beyond Birmingham as key drivers. The findings signal tighter competition for renewals frameworks, pressure on design and project management capacity, and potential delays to geotechnical and civils packages on secondary routes.

Drypool Bridge in Hull has reopened to traffic after a 10.5-week full closure, as Esh Construction completes the initial phase of a major repair and strengthening programme on the key river crossing. The works form part of a staged refurbishment to extend the operational life of the movable bridge structure and improve reliability of its mechanical and structural components. Engineers and contractors now shift to the next phase while maintaining traffic flow, which will influence access planning and inspection regimes for similar ageing urban bridges.

Homes England has awarded Transport for London a £23M grant to deliver a new bus link that will unlock the proposed Docklands Light Railway extension to Thamesmead, a key growth area in east London. The bus corridor is expected to establish passenger demand and safeguard a future DLR alignment, reducing risk for subsequent rail and geotechnical works across challenging former industrial and riverside land. For civil engineers, the funding signals early-stage transport-led regeneration, with phased surface transport preceding higher-capacity rail infrastructure.

A proposed £5bn merger between two UK-listed infrastructure investment trusts has collapsed after key shareholders objected to the combined vehicle’s perceived risk profile. Investors were reportedly concerned about increased exposure to higher-risk assets within the trusts’ mixed portfolios of transport, energy and social infrastructure. The failure of the deal may constrain capital available for large, long-duration projects and signals that institutional backers are currently wary of structures concentrating construction and demand risk.

Sealants & Pavement Adhesives, led by Managing Director Kevin De-Simone, is positioning itself as one of the few Australian suppliers offering both pavement sealing machinery and bituminous sealant products from a single source. The family-run business provides crack sealing equipment alongside hot-applied joint sealants and pavement adhesives, targeting road maintenance crews seeking tighter integration between plant and consumables. For asset owners and contractors, the combined supply and training model is aimed at improving seal performance and consistency on sprayed seal and asphalt rehabilitation works.

Grassroots road safety funding in Victoria will see 316 local football and netball clubs share $700,000 through the Transport Accident Commission’s Club Rewards Program, with each AFL Victoria‑aligned club able to earn up to $10,000. The grants support community‑led campaigns on issues such as speed, drink‑driving and seatbelt use around regional and metropolitan grounds, where match‑day traffic and informal parking often create high‑risk conflict points. For road engineers and planners, the programme may generate local data and partnerships useful for targeting low‑cost safety treatments near suburban and rural sports precincts.

Miller Homes Scotland West has acquired the 33-hectare former Clydesdale Steelworks brownfield site in Bellshill to deliver the Hawthorn Green residential development, the first phase of a wider regeneration exceeding 430 homes. Phase one will comprise 97 three-, four- and five-bedroom semi-detached and detached units, with initial site preparation starting this month and main construction scheduled for next year. First completions are targeted for early 2027, signalling long-term remediation, groundworks and infrastructure demands on a large ex-industrial site in North Lanarkshire.

WHC Hire Services in the West Midlands has become the first UK firm to offer an electric Kubota mini excavator by converting a conventional diesel unit using its in-house Requip Electric Retrofit system. The retrofit replaces the original engine with a battery-electric powertrain, allowing contractors to use familiar Kubota compact excavators on zero-tailpipe-emission sites and in low-noise, enclosed or urban environments without waiting for OEM electric models.

Southern Water has signed a £7m, six-year framework with Dutch firm Samotics to roll out its SAM4 electrical signature analysis (ESA) condition monitoring system across around 600 wastewater and clean water sites in southern England. A one-year trial on 1,458 critical assets detected 63 failures on submersible sewage pumps and other pumping equipment, avoiding an estimated £5m in damage and penalties by catching blockages, air locks and mechanical faults early. SAM4 analyses real-time current and voltage signals, with AI plus human-in-the-loop validation delivering 97% fault-classification accuracy and under 1% false positives via a remote dashboard.

DSM Demolition has begun an 18‑month contract to clear major industrial structures at the former Fiddlers Ferry coal‑fired power station near Warrington for Peel NRE’s regeneration scheme. Works cover specialist asbestos removal, demolition of remaining coal conveyors, the flue gas desulphurisation plant, precipitators and storage silos, plus systematic de‑planting of the turbine hall and control room. Peel NRE is supported by D360 Consulting Engineers, Addleshaw Goddard, Arcadis and Turley, signalling substantial technical, legal and planning input as the brownfield site is prepared for mixed‑use redevelopment.

Tilbury Douglas has appointed Jack Dixon as managing director of its fit-out subsidiary Paragon, signalling a push to expand its London-focused interior construction and refurbishment workload. Dixon joins from Structure Tone in London, where he spent nine years and most recently served as divisional director, bringing major commercial fit-out experience. The move targets growth with private sector office and commercial clients while maintaining Paragon’s core public sector and central government fit-out portfolio, particularly in a buoyant London market.

Cirencester-based labour supplier Hercules has opened a permanent office in Motherwell to serve Scottish construction and utilities projects with both site-based and office-based skilled staff. Chief executive Brusk Korkmaz says the move targets Scotland’s acute skills shortage in renewables, transport and civil engineering, offering pre-trained, safety-focused teams able to mobilise quickly on major infrastructure works. The company plans to invest in local talent pipelines, apprenticeships and digital workforce management to give contractors compliant, productive crews and support long-term project delivery capacity.

Kier has secured two NEC4 Engineering and Construction Contract packages worth £44.4m to upgrade 12 Southern Water wastewater treatment works under the £3.1bn AMP8 strategic delivery partner framework. A £19.9m ECI contract covers early-stage design and development at six sites including Chickenhall (Eastleigh), Fullerton and Paddock Wood to increase capacity and meet WINEP-driven environmental and population requirements. A second £24.5m ECI contract covers six further works such as Tonbridge and Felbridge, focusing on process upgrades for tighter ammonia, phosphorus and BOD removal performance.

Balfour Beatty Rail is rolling out Engine Carbon Clean (ECC), an Advanced Hydrogen Technologies system that injects on-demand hydrogen into engine air intakes, across its entire tamper fleet after trials showed a 15.79% emissions reduction over a simulated full-year maintenance cycle. The non-intrusive process targets carbon build-up in combustion engines to improve fuel efficiency, extend engine life and cut CO₂, CO, NOx and N₂O, with road-vehicle deployments reporting up to 30% fuel and CO₂ savings. Delivered with K2C Rail and 1stinrail (RSK Group), ECC is configured to meet rail standards and support IFRS-aligned ESG reporting.

German materials firm FibreCoat has developed zinc-coated fibres for use in reinforced concrete, claiming cathodic corrosion protection for embedded steel in highly alkaline environments where aluminium rapidly degrades. Dispersed within concrete mixes for marine and coastal structures, the zinc fibres could, subject to testing, extend asset service life by 20–30 years at a fraction of the cost of titanium fibre reinforcement. Chief executive Robert Brüll positions the heavier, less reflective zinc coating as a structural, durability-focused alternative for multi-storey car parks, docks, ports and bridges.

Picko Global is expanding a circular resource recovery model that processes mine tailings and waste rock through modular plants in Southern Africa to extract residual metals and construction aggregates. The company uses mobile crushing, screening and dense media separation units to treat legacy dumps and current waste streams, targeting fine fractions often bypassed by conventional concentrators. For mine operators, the approach offers potential reductions in tailings storage volumes and rehabilitation liabilities while generating saleable products from previously stranded material.

The Minerals Council of Australia has backed the Federal Government’s National AI Plan, urging a “dynamic” regulatory approach that supports rapid deployment of AI across mine planning, autonomous haulage and remote operations centres. MCA argues that prescriptive rules could slow adoption of tools such as machine-learning orebody models and predictive maintenance systems on large haul truck fleets and fixed plant. For geotechnical and processing teams, the stance signals continued policy support for data‑driven decision‑making rather than tight up‑front constraints on specific AI technologies.

Glencore plans to lift copper output to about 1.6 Mt/y by 2035 and above 1 Mt/y by 2028, but has cut its 2026 guidance to 810,000–870,000 t from 930,000 t after setbacks at Chile’s Collahuasi joint venture with Anglo American. The company will restart the Alumbrera mine in Argentina in Q4 2026, targeting over four years some 75,000 t copper, 317,000 oz gold and 1,000 t molybdenum, using existing MARA concentrator and logistics infrastructure for brownfield synergies. A $1 billion cost-saving drive by end‑2025 includes about 1,000 job cuts and a broad operational review.

Copper prices on the London Metal Exchange hit a new record above $11,400 per tonne after a surge in warehouse withdrawal orders signalled rapidly tightening available stocks and pushed the global benchmark up more than 30% year-to-date. Traders are diverting large volumes of metal to US ports as Comex futures price in potential 50% tariffs on primary copper from 2027, while producers prepare record 2026 premiums for European and Asian buyers. Supply risk is amplified by mine disruptions at Ivanhoe’s Kamoa-Kakula complex in the DRC and Glencore’s 40% output drop since 2018, raising the prospect of a Q1 2026 squeeze.

Ivanhoe Mines expects contained copper output at the Kamoa-Kakula complex in the DRC to fall to 380,000–420,000 tonnes in 2026, down from 437,061 tonnes of copper concentrate in 2024, before rising about 30% to 500,000–540,000 tonnes in 2027 at grades of 3.5–4.5%. Seismic-induced flooding in May halted underground mining for about three weeks, with dewatering now 70% complete in the western zone and 60% in the eastern zone, and 13.4 km of workings rehabilitated, including 4.6 km dewatered. A revised life-of-mine plan due late Q1 will assess lifting mining rates to 17 Mt/y, up from about 6 Mt of ore expected in 2026, and a potential new concentrator.

Agnico Eagle topped MINING.COM’s November Global Mining Power Rankings large-cap category with 12.21% of votes, backed by a 108% Toronto share price gain over 12 months, reaffirmed 2024 guidance of 3.3–3.5 Moz and on-schedule underground expansion at Canadian Malartic, plus an $80 million Avenir Minerals critical minerals push following a $180 million stake in Perpetua’s Stibnite gold‑antimony project. Ivanhoe Electric led small caps with 5.1% of votes on progress at the Santa Cruz copper project in Arizona and a “technology-driven” US exploration platform. District Metals headed micro caps with 6.1% after Sweden lifted its seven-year uranium mining ban, improving the outlook for its Viken uranium‑vanadium project with an inferred 1.5 billion lb uranium resource and a market value above C$153 million.

Appian Capital Advisory has provided a $150 million package, combining a senior secured debt facility and a gold stream agreement, to support Atlantic Group’s up to $305 million acquisition of Barrick’s Tongon gold mine in Côte d’Ivoire. Barrick has received $192 million in cash with up to $113 million contingent on gold price and resource milestones, while Atlantic will run a downside gold price protection programme to stabilise mine cash flows. Tongon, producing about 140,000 oz of gold in 2025, holds 620,000 oz proven and probable reserves plus 700,000 oz measured and indicated resources across a 2,136 km², five‑concession land package.
