Graham has begun structural steel erection for the new Castle Rock School in Coalville, Leicestershire, being delivered for the Department for Education and Lionheart Educational Trust. The steel frame phase establishes the primary load-bearing structure and grid, setting out future integration of precast floor units, façade systems and M&E penetrations. For civil and structural teams, this marks the point where foundation performance, column base tolerances and connection detailing will start to be tested against design assumptions on programme-critical timescales.

Calls for the UK government to move from signalling to delivery on its National Infrastructure Strategy centre on giving investors certainty over multi‑decade assets such as major rail upgrades, strategic road renewals and regulated water networks. Commentators warn that repeated policy reversals on projects like HS2 and delays to the £40bn+ pipeline for energy transition assets are pushing up risk premia and diverting capital to markets with clearer frameworks. For contractors, consultants and materials suppliers, the message is to plan around regulatory stability, long‑term funding models and credible delivery timetables rather than headline announcements.

£31M safety upgrades at Lambeth Bridge have been completed by Transport for London and the Tarmac Kier Joint Venture, reconfiguring both the northern and southern roundabouts at what has been labelled one of London’s most dangerous junctions. Works focus on segregated cycle lanes, simplified traffic movements and redesigned pedestrian crossings to cut conflict points between vehicles, cyclists and foot traffic. For civil and highways engineers, the scheme signals continued investment in complex urban junction remodelling, with emphasis on geometry changes and user separation rather than purely signal-control solutions.

Barhale has secured a £12.5M contract from Thames Water to carry out statutory inspection and maintenance on the Thames Water Ring Main (TWRM) and key North London Abstraction and New River Zone raw water tunnels. The programme will focus on large-diameter, deep tunnel assets that form the core of London’s potable water transfer system, where access, ventilation and confined-space working will be critical planning constraints. Geotechnical and structural findings from the inspections are likely to drive future lining repairs, leakage control and long-term asset life modelling for these strategic tunnels.

Thames Water is reported by the BBC to be a step closer to nationalisation, raising the prospect that its £18bn-plus capital programme for London’s ageing sewers, trunk mains and treatment works could shift to direct government control. Any move to public ownership would affect financing and delivery of long-term infrastructure such as the Thames Tideway interfaces, major resilience upgrades to Victorian-era assets, and AMP8 regulatory commitments. Contractors, consultants and materials suppliers with framework positions should prepare for potential changes in procurement models, risk allocation and project phasing.

Resouro Strategic Metals’ PEA for the Tiros rare earths and titanium project in Minas Gerais, Brazil, outlines a 500,000 t/y starter operation producing about 90,000 t/y TiO₂ concentrate and 3,636 t/y TREO over an initial 20-year mine life, with post-tax NPV8 of $714.9 million and IRR of 44.2%. The deposit hosts 1.4 billion tonnes of measured and indicated resources at 12% TiO₂ and 4,000 ppm TREO, with the starter pit targeting less than 1% of this inventory. Near-surface, low-strip mineralisation, conventional processing, and reported recoveries of 68.7% TiO₂ and 67% REE to mixed carbonate underpin the staged development strategy.

Canada has granted Italy priority access to its critical mineral reserves, reinforcing a year of bilateral deals including Eni’s nearly C$100 million offtake-linked investment in Nouveau Monde Graphite’s Matawinie graphite project in Québec and Italy’s entry into the Critical Minerals Production Alliance. Rome plans to collaborate with Ottawa on stockpiling, with a clear focus on battery metals and defence-related inputs such as graphite, nickel and rare earths. Parallel talks cover Canada’s planned purchase of Leonardo M‑346 advanced jet trainers and a proposed Defence, Security and Resilience Bank to finance long-term defence projects.

Vedanta Group has completed its long-planned demerger, listing four new companies on the Bombay Stock Exchange and National Stock Exchange covering critical minerals, aluminium, oil and gas, power, and iron and steel. The move separates these commodity verticals into focused entities, giving investors direct exposure to discrete value chains from bauxite-to-aluminium and iron ore-to-steel, alongside upstream hydrocarbons and power generation. For mine planners and project financiers, the new structure may change capital allocation, JV options and offtake strategies across Vedanta’s Indian and African assets.

Boliden’s Aitik open-pit copper mine has secured a renewed environmental permit from Sweden’s Land and Environment Court, authorising continued production of up to 45 Mt of ore per year. The decision also approves specified methods for staged tailings dam raising and revised water management practices, giving regulatory backing to Aitik’s long-term waste storage and process water handling strategy. For geotechnical and process engineers, the ruling provides clarity on allowable dam construction techniques and water balance controls for one of Europe’s largest copper operations.

Southern Water has started enhancement works on the River Anton along Western Avenue in Andover, Hampshire, targeting a constrained urban reach adjacent to key utilities and transport links. The project is expected to focus on channel stabilisation, bank protection and habitat improvements, likely involving in-channel structures, local scour control and regrading of embankments to manage flood risk and sediment transport. Contractors and designers will need to manage works within a narrow corridor, maintaining service continuity and access while working in and around live watercourses.

Ports are being forced to retrofit safety‑critical assets such as quay walls, fender systems and ageing crane rails while remaining fully operational, as container volumes, vessel sizes and regulatory scrutiny all rise. Engineers are increasingly sequencing works around tidal windows and berth occupancy, using modular precast elements, temporary moorings and staged isolations to avoid taking entire berths out of service. The approach demands tighter interface management between marine civils, terminal operators and pilots, with construction tolerances and access planning driven by live navigation and cargo‑handling constraints rather than conventional shutdown conditions.

Railway upgrade works on the Midland Mainline will disrupt services between Bedford and London over the next two weekends as engineers tackle a concentrated package of track and systems improvements. Network Rail teams are expected to renew sections of rail and ballast, adjust overhead line equipment and carry out signalling upgrades on this intensively used commuter and intercity corridor. Civil and track engineers should anticipate temporary speed restrictions, altered possession windows and access constraints for any parallel works in the Bedford–London section during this period.

Sinkholes discovered by Network Rail engineers on a rail bridge outside Purley have forced the closure of all lines between Purley and East Croydon, severing direct rail links between central London and Gatwick Airport. The defect was identified during planned engineering works, prompting immediate suspension of services on this key section of the Brighton Main Line. Geotechnical teams now face urgent investigation of foundation conditions and void extent beneath the bridge, with stabilisation and monitoring requirements likely to dictate the duration of disruption.

Amey has secured two Eastern Region Assessment Contracts (ERAC) with Network Rail worth a combined £40M, covering structural and geotechnical assessments across the Eastern route. The frameworks will support asset condition evaluation and capacity checks on bridges, culverts, retaining walls and earthworks, informing renewals and strengthening works on key passenger and freight corridors. For consultants and contractors, the awards signal continued demand for detailed assessment to optimise life extension and target capital interventions on ageing rail infrastructure.

Solar-1, a new NOAA satellite to be stationed at the Sun–Earth L1 Lagrange point, will extend warning times for geomagnetic storms that can induce damaging currents in long high-voltage transmission lines and transformers. By providing earlier, higher-resolution measurements of solar wind speed, density and magnetic field, Solar-1 will allow grid control centres to pre-emptively reconfigure networks, reduce loading on vulnerable 400kV and 275kV circuits, and adjust reactive power support. For civil and electrical engineers, this supports more robust design and operational planning for geomagnetically induced current resilience.

Undergrounding 20km and 50km high-voltage transmission sections is significantly more expensive than using overhead lines on steel lattice pylons, according to a UK government-commissioned cost study by Ramboll. The analysis compares full-life costs for underground cable systems – including deep trenching, joint bays, transition compounds and higher repair complexity – against conventional overhead construction. For project teams weighing community pressure to bury lines, the findings signal materially higher capex and O&M, with major implications for route selection, consenting strategies and whole-life cost assessments.

Esso has been fined £1M by the UK Health and Safety Executive after 2.4t of highly flammable liquefied petroleum gas leaked from ageing plant at ExxonMobil’s Fawley Refinery due to failures in managing equipment integrity. The incident, which exposed workers to “life-threatening risks”, stemmed from inadequate inspection and maintenance of pipework and associated fittings in a hazardous area of the site. Process safety engineers and asset managers are likely to face closer scrutiny of inspection regimes, corrosion monitoring, and lifecycle replacement strategies for high-pressure LPG systems.

Greater Manchester mayor Andy Burnham has pledged to reinstate the cancelled HS2 Phase 2 leg between Birmingham and Manchester if he becomes prime minister, reviving a high-speed corridor originally designed for 360km/h operation and released capacity on the West Coast Main Line. The commitment would reopen questions on safeguarding of the former HS2 route, reactivation of major structures such as the planned Crewe hub and Manchester Piccadilly underground station box, and integration with Northern Powerhouse Rail and existing classic-compatible rolling stock strategies.

Arafura Rare Earths is targeting a September construction start on its A$1.23 billion Nolans project, 1,140 km southeast of Darwin, to create Australia’s first fully integrated ore-to-oxide rare earths mine and refinery producing 4,440 tonnes per year of NdPr oxide over a 38-year life. The project, now backed by A$887 million in equity and about $1.01 billion in debt, includes an on-site oxide processing plant accounting for 90% of capex and aims to produce 144,000 tonnes per year of high-purity phosphoric acid byproduct. Offtake deals already cover up to 3,820 tonnes per year of NdPr oxide with Hyundai, Kia, Siemens Gamesa, Traxys and Australia’s Critical Mineral Strategic Reserve, with contracts indexed to non-Chinese rare earth price benchmarks.

Gina Rinehart has taken a “significant stake” in Elon Musk’s SpaceX, with Australian Financial Review valuing the investment at over $1 billion within SpaceX’s record $75 billion IPO, signalling a bet that launch and lunar infrastructure will drive long-term demand for critical minerals. Hancock Prospecting already holds major positions in Lynas Rare Earths and MP Materials, and CEO Garry Korte flagged potential commercial arrangements between these assets and SpaceX. For mining strategists, the move ties terrestrial rare earths and battery metals portfolios directly to NASA’s Artemis timeline, lunar ISRU concepts and early asteroid-mining experiments such as AstroForge’s metallic NEA mission.

Petra Diamonds’ move to place the Finsch mine into business rescue and start a Section 189A retrenchment process at Cullinan has put about 689 and 1,090 jobs respectively at risk, according to South Africa’s National Union of Mineworkers. Business rescue practitioners Daniel Theodorus van Jaarsveld and Luke Bernard Saffy have assumed control at Finsch, where production is being suspended while a creditor-backed restructuring plan is drafted. The cuts follow a four‑year slump in natural diamond demand, with global output expected to drop to about 90 million carats in 2026, the lowest since 1987.

Montage Gold has increased total contained resources at its Koné gold project in Côte d’Ivoire by almost 58%, to 244 million measured and indicated tonnes at 0.8 g/t (6.2 Moz) plus 93 million inferred tonnes at 0.68 g/t (2 Moz), following roughly 330,000 metres of drilling since the 2024 feasibility study. Satellite deposits Gbongogo Main and South and Koban now host 1.6 Moz measured and indicated at 1.51 g/t and 766,000 oz inferred at 1.34 g/t, materially lifting potential head grades for early pit phases. Construction at Koné remains on budget and ahead of schedule, with first gold pour targeted for late Q4 2026 and a further 90,000-metre drill programme in progress across the district.

Gold prices are forecast by UBS to fall a further $300–$900/oz, with strategists Dominic Schnider, Giovanni Staunovo and Wayne Gordon seeing momentum driving the market towards $3,850–$4,000/oz in the near term after a muted reaction to the US–Iran conflict and stronger-than-expected US jobs data. The bank has already cut its year-end target from $5,900 to $5,500/oz after January’s record near $5,600/oz was largely unwound as higher real yields and a possible Fed rate hike weighed on bullion. UBS remains constructive over 12 months, assuming up to 50 bps of Fed cuts in 2027, continued central bank buying and pressure from US fiscal deficits.

Rising resource nationalism and expropriatory measures in African cobalt, copper, gold and lithium projects are driving more investor–state arbitrations, but investors often doubt they can monetise awards against states with limited attachable foreign assets and constrained reserves. Hogan Lovells’ Markus Burgstaller and colleagues with Kroll urge integrating arbitration counsel and asset tracers from the outset to map non-immune assets, using London’s courts and financial infrastructure to target bank accounts, commercial property and bond payment flows. They stress politically sensitive assets, coordinated reputational pressure on lenders and markets, and timing enforcement around government changes to force negotiated settlements rather than purely symbolic seizures.
