    Hudson Tunnel funding deadline: schedule and risk takeaways for project teams

    Federal funding for New York’s US$16bn Hudson Tunnel Project has been frozen, forcing the Gateway Development Commission to suspend works from 6 February after spending over US$1bn and employing about 1,000 site workers. A Manhattan federal judge has issued a temporary restraining order, giving the administration until 5 p.m. on 12 February to restore reimbursements or appeal, while contractors warn that demobilisation, resequencing and remobilisation will add cost and delay. Sites are now in “safe-pause” mode, with dewatering, ground support and environmental monitoring maintained, and assembly of two Herrenknecht TBMs in New Jersey likely to slip beyond the planned spring 2026 launch without funding certainty.

    Gold price climbs on US–Iran ceasefire: risk and planning notes for miners

    Gold jumped as much as 3% to a three-week high above $4,850/oz after the US and Iran agreed a two-week ceasefire, easing fears that Middle East-driven oil price spikes would lock in higher inflation and delay US Federal Reserve rate cuts. Prices are still down about 9% since the war began and remain below the near-$5,600/oz record hit earlier in 2026, with analysts warning the rebound is fragile and highly sensitive to any breakdown around the Strait of Hormuz. Longer term, Goldman Sachs and Wells Fargo maintain bullish targets of $5,400/oz and $6,300/oz respectively.

    Vale CEO charges reinstated: Brumadinho dam failure lessons for engineers

    Brazil’s Superior Court of Justice has reinstated criminal charges against former Vale CEO Fábio Schvartsman over the 25 January 2019 Brumadinho Córrego do Feijão tailings dam collapse, which killed more than 250 people and erased about US$19 billion from Vale’s market value in a single day. Federal prosecutors cited extensive internal documentation alleging Schvartsman assumed the risk of death by not acting on known instability issues at the upstream tailings structure, overturning a Minas Gerais court’s habeas corpus ruling. The decision restores 16 defendants, including ex‑Vale staff and TÜV SÜD consultants, with over 160 witnesses scheduled and hearings expected to run into next year, keeping corporate accountability for dam safety in sharp focus.

    Industrialising SMR delivery in the UK: design and layout notes for engineers

    Industrialising delivery of small modular reactors (SMRs) is being pushed as critical if the UK is to convert its renewed nuclear ambitions into a scalable, low‑carbon baseload fleet. Proponents argue for factory‑fabricated reactor modules, standardised civil works and repeatable balance‑of‑plant designs, rather than bespoke, site‑specific construction seen on gigawatt‑scale projects like Hinkley Point C. For civil and geotechnical engineers, this points to highly standardised nuclear island foundations, modular containment structures and logistics‑driven site layouts that can be replicated rapidly across multiple locations.

    BRICS+ central banks now hold about 6,000 tonnes of gold, or 17.4% of global reserves, up from 11.2% in 2019, with Russia (2,336 tonnes), China (2,298 tonnes) and India (880 tonnes) the largest holders. Annual official-sector gold buying has averaged roughly 1,000 tonnes over the past four years, doubling after 2022 sanctions on Russia, and BRICS+ countries accounted for more than half of purchases between 2020 and 2024. The report flags Saudi Arabia as a potential “wild card”, noting that a shift to a 5% gold allocation could alone match projected total central bank demand for 2026.

    BNG for NSIPs delay: implications for DCO strategy and design teams

    The BNG Federation accuses the UK government of breaking its promise to set a clear timetable for applying biodiversity net gain (BNG) rules to nationally significant infrastructure projects (NSIPs), leaving major schemes in a “regulatory vacuum”. Developers of large highways, energy and rail projects currently lack certainty on when and how the statutory 10% BNG requirement will apply, complicating land acquisition, habitat design and long-term management plans. The federation warns that without a defined start date and guidance, DCO applications and environmental impact assessments risk delay and redesign.

    Goldman copper downside warning: pricing risk lens for mine planners

    Copper’s early-2026 rally above $14,500/t has fully reversed, with prices now around $12,000/t and down 2.5% year-to-date after the Iran war and Strait of Hormuz disruptions pushed energy costs higher and clouded global growth. Goldman Sachs, led by analyst Aurelia Waltham, has cut its 2026 base-case copper target to $12,650/t from $12,850/t, versus an estimated “fair value” of about $11,100/t, and warns of a “severely adverse” downside scenario if the strait stays blocked. For project modellers and mine planners, the bank’s note signals weaker near-term demand assumptions and greater price risk around expansion and hedging decisions.

    Revival’s Utah Mercur gold mine: drilling, capex and schedule for project teams

    Revival Gold’s 2025 drilling at the past-producing Mercur gold project in Utah returned one of its strongest South Mercur intercepts to date, with hole RMC25-031 cutting 74 m at 2.8 g/t Au from 91 m downhole, including 13 m at 8 g/t from 13 m depth, and RMC25-032 intersecting 84 m at 1.1 g/t from 14 m. The company, which now owns 100% of Mercur after buying Barrick’s remaining stake, is advancing a heap leach operation based on a PEA outlining US$208 million capex for a 10-year, 95,000 oz/y mine. A 16,000 m follow-up drilling and engineering programme will feed into a pre-feasibility study targeted for Q1 2027, ahead of a potential construction decision in 2028 and first production in 2029.

    MAXAM MS406 45/65R45 loader tyre: fitment and cost-per-hour notes for mines

    MAXAM Tire has added a 45/65R45 size to its MS406 E4/L4 off-the-road tyre line, targeting heavy loader applications in mining and large quarry operations. The MS406 design uses a deep tread pattern and reinforced casing to handle high load cycles and abrasive conditions, aiming to extend service life and reduce unplanned downtime on large wheel loaders. For mine operators, the new size broadens fitment options on 45-inch rims, supporting tyre standardisation across mixed fleets and tighter cost-per-hour control.

    Pilot Crushtec TwisterTrac Stage V at Hillhead: fleet and emissions notes for engineers

    Pilot Crushtec will use the Hillhead 2026 show (23–25 June, UK, c.20,000 visitors expected) to launch its latest-generation TwisterTrac VS350E Stage V mobile crusher and push for an expanded European dealer network. The VS350E, a track-mounted vertical shaft impact unit, is configured for quarrying, construction and recycling applications where EU Stage V emissions compliance is now mandatory. Stronger distribution in Europe signals more local support and parts availability for high-spec mobile crushing fleets on both greenfield and brownfield sites.

    East Somerset Junction Easter upgrades: track renewal lessons for rail engineers

    Engineers restored rail services through Somerset after completing Easter bank holiday works at East Somerset Junction, between Westbury and Taunton, several hours ahead of schedule. Teams replaced life-expired rail, sleepers and ballast on this key junction, working within a tight multi-day possession to minimise disruption on the route. The renewal improves track geometry, drainage and bearing capacity at the junction, reducing future maintenance interventions and supporting higher reliability for passenger and freight operations.

    McEwen Copper’s $4B Los Azules plan: project economics and design notes for engineers

    McEwen Copper is seeking about $4 billion in financing, including export-credit support from agencies such as the US Export-Import Bank and the US International Development Finance Corp., to build the Los Azules copper project in Argentina. The feasibility-stage operation targets copper cathode production, not concentrate, with planned output of 205,000 tonnes per year for the first five years, then averaging 148,000 tonnes over a projected 22-year mine life, extendable to 33 years. Backers include Stellantis and Rio Tinto’s Nuton, with a $300 million IPO and first production by 2030 under consideration.

    Hunterston B AGR transfer: decommissioning workstreams mapped for contractors

    Hunterston B in North Ayrshire has become the first advanced gas-cooled reactor (AGR) nuclear power station to transfer from EDF to direct UK Government ownership as it moves into the full decommissioning phase. The twin-reactor AGR plant, which ceased generation in 2022 after more than four decades of operation, will now be managed through the Nuclear Decommissioning Authority’s framework. For civil and geotechnical contractors, the shift signals upcoming packages for reactor dismantling, large reinforced concrete demolition, waste encapsulation structures and long-term coastal site management.
