A major junction in Stockport has reopened after a year-long, £20M reconstruction replacing the Greek Street bridge over the West Coast Main Line. The rail overbridge, which carries a busy roundabout above one of the UK’s highest‑traffic intercity corridors, was fully removed and rebuilt under extended possessions to minimise disruption to Avanti West Coast and freight services. For civil and rail engineers, the scheme illustrates the logistical and staging demands of replacing a critical overbridge on a live main line in an urban setting.

A Ten Minute Rule Bill introduced by a backbench MP in the House of Commons seeks to overhaul how personal protective equipment is specified, designed and procured across the public sector, including for construction and infrastructure works. The proposal targets inclusive PPE sizing and fit for women and smaller-bodied workers, rather than relying on scaled-down male templates, and would place duties on contracting authorities to require compliant kit in framework and project tenders. If adopted, it could force revisions to site safety policies, supplier frameworks and risk assessments where ill-fitting PPE currently compromises protection and task performance.

Scotland will not support new nuclear projects, with ministers rejecting small modular reactors and fusion as “unproven” and “experimental” and instead prioritising capital for onshore and offshore wind, solar and marine renewables. The policy stance signals future grid and civil works centred on high-penetration variable generation, storage and transmission upgrades rather than nuclear-grade foundations, containment structures and cooling water infrastructure. Developers can expect planning and funding levers to favour large offshore wind arrays, repowering of existing wind farms and associated port, cable route and substation construction.

A £165M government roads fund has been launched to deliver junction upgrades, link roads and access improvements needed to unlock “stalled” housing and employment sites across England. Funding will target off-site highway constraints that currently block planning consents, such as substandard single-access routes, overloaded roundabouts and missing spine roads into large allocations. For civil and geotechnical teams, this signals near-term demand for design and delivery of new connectors, localised widening, pavement reconstruction and associated drainage and utilities diversions tied directly to specific development parcels.

Tameside Council has launched a £54M highways maintenance framework tender aimed at upgrading carriageways, footways and associated assets across the borough, with scope for use by other Greater Manchester and neighbouring authorities. The multi-supplier framework is expected to cover routine and reactive maintenance, resurfacing, drainage works and structures repairs, favouring contractors offering innovative methods such as low‑carbon asphalts and digital asset management. Bidders will need to demonstrate capability for working under live traffic, coordinating with utilities, and delivering to tight possession windows.

Balfour Beatty has joined the High Speed Rail Group (HSRG), adding one of the UK’s largest design-and-build contractors to an organisation that advocates for high-speed rail policy and delivery across schemes such as HS2 and Northern Powerhouse Rail. The move brings Tier 1 experience in complex rail civils, including bored tunnels, long-span viaducts and high-speed trackbed formation, directly into HSRG’s technical and policy work. For geotechnical and civil engineers, this signals closer contractor input into standards, constructability, and value engineering on future high-speed corridors.

Two headline contracts worth about £3bn have been signed for Britain’s fourth high‑voltage subsea electricity “superhighway” between Scotland and England, advancing a major reinforcement of north–south transmission capacity. The deals cover manufacture and installation of long‑distance HVDC subsea cables and associated converter station equipment, forming part of the network upgrades needed to move larger volumes of Scottish offshore wind and other renewables to English demand centres. Contractors will face complex marine installation, landfall civils and grid interface works, with tight coordination around existing subsea infrastructure.

BULK26 in Melbourne on 10–11 April will focus on predictive conveyor monitoring, next-generation transfer point guarding and dust control technologies across ports, terminals, stockyards and mine load‑out facilities. Exhibitors and speakers will cover condition‑based maintenance for high‑tonnage conveyor systems, advanced chute and liner designs to reduce impact wear, and engineered guarding solutions that maintain AS/NZS compliance while improving access. For plant, maintenance and materials‑handling engineers, the event offers direct exposure to vendors and case studies targeting common bottlenecks such as spillage, belt misalignment and unplanned conveyor downtime.

AIC Mines has reported record copper ore reserves at its Eloise and Jericho projects in Queensland, following an updated mineral resource and reserve estimate that extends mine life and supports higher long-term throughput at the Eloise processing plant. The combined underground operations, which target structurally controlled, high-grade sulphide lodes, are being optimised around existing decline access and ventilation infrastructure to reduce unit costs and improve stope sequencing. Geotechnical and mine planning teams will need to reassess ground support, paste fill requirements and scheduling to align with the larger reserve base and extended production horizon.

Aeris Resources has more than doubled the scale of its Golden Plateau drilling programme at the Cracow gold operations in Queensland after continued high‑grade intercepts from recent holes. The expanded campaign targets extensions of the historic Golden Plateau orebody beneath and along strike of previous workings, aiming to convert near‑mine mineralisation into additional underground reserves. For mine planners and geotechs, the move signals a stronger focus on resource definition drilling around existing infrastructure rather than greenfield step‑out, with potential to extend Cracow’s production profile.

Queensland Mining & Engineering Exhibition (QME) will return to the Mackay Showgrounds from 22–24 July 2024, bringing together underground coal, METS and decarbonisation suppliers across more than 250 exhibitors. The event will feature live demonstrations of autonomous and battery-electric equipment, mine ventilation and dust-control systems, and digital fleet management platforms tailored to Bowen Basin operations. For geotechnical and operations teams, QME offers direct access to OEM engineers, case studies from nearby longwall and dragline sites, and cross-industry sessions on decarbonising diesel haulage and improving asset life.

Canada and Quebec are negotiating a rescue of Glencore’s Horne Smelter in Rouyn-Noranda, the country’s only copper smelter and one of the few North American plants able to treat both copper concentrate and about 100,000 tonnes of e‑waste annually, after the company paused nearly C$1 billion of planned investment over tighter arsenic limits. Quebec may delay a new 15 ng/m³ arsenic cap to 2029 and keep it to at least 2033, while Ottawa considers roughly C$150 million in support for pollution-control upgrades, despite the proposed limit remaining five times above the provincial safety threshold. Closure would further strain North American smelting capacity, disrupt supply to customers such as Nexans’ Montreal operations, and intensify local health and legal pressures already linked to elevated chronic obstructive pulmonary disease rates and a certified class-action lawsuit.

Montage Gold has increased measured and indicated resources at the Koné deposit in Côte d’Ivoire to 4.63 million oz grading 0.69 g/t, a 21% grade uplift, while Gbongogo Main now holds 783,000 oz indicated at 1.51 g/t after a 174,000-metre, 12.5-metre–spaced drilling campaign refined higher-grade shoots and structural controls. The fully funded project, with initial capex of $545 million and targeting c.300,000 oz/year over the first eight years of a 16-year life, remains on-budget and ahead of schedule for first gold in Q4. Financing includes a $625 million Wheaton Precious Metals gold stream (up to 19.5% of payable production, then stepping down) plus $125 million in Zijin-backed debt and subordinated streaming.

Fireweed Metals has secured a C$61.5 million non-brokered placement from JX Advanced Metals and the Lundin Family Trusts to advance its Macpass zinc-lead-silver and Mactung tungsten projects in Yukon, plus the early-stage Gayna zinc-germanium-gallium project in the Northwest Territories. Macpass currently hosts 56 million indicated tonnes at 5.49% zinc, 1.58% lead and 24.2 g/t silver, while nearby Mactung holds 41.5 million indicated tonnes at 0.73% WO₃, with feasibility work targeting completion in early 2027. Recent backing also includes $15.8 million from the US Department of Defense and up to C$12.9 million from Canada’s Critical Minerals Infrastructure Fund to connect Macpass to the road network.

Washington is committing up to $1.6 billion to USA Rare Earth to develop the Round Top mine-to-magnet chain in Texas, despite the project’s low-grade, mineralogically complex deposit and the company having no commercial mining or magnet output ahead of a targeted late‑2028 start. The deal would see the Commerce Department retain an equity stake even without investing cash, while USA Rare Earth must still raise $1.5 billion via Cantor Fitzgerald, run by Commerce Secretary Howard Lutnick’s sons, prompting conflict-of-interest concerns. Parallel ventures such as ReElement Technologies and MP Materials show continued dependence on federal price floors, grants and state-backed financing to keep US rare earth projects viable against Chinese competition.

Agnico Eagle Mines is taking a 14.21% non-diluted stake in Cascadia Minerals by buying 29.31 million units at C$0.26, with attached warrants that could lift its interest to 19.9%, providing about C$7.6 million of a total C$8.9 million financing. The funds will advance Cascadia’s 180 km² Carmacks copper-gold project in central Yukon, which has a 2023 PEA outlining a post-tax NPV5 of C$330 million, 38% IRR and measured/indicated resources of 651 million lb copper and 302,000 oz gold, ahead of a 15,000 m drill campaign in spring 2026. A parallel strategic alliance in Yukon’s Stikine Terrane will see Agnico fund up to C$3 million over three years per project (and potentially a further C$12 million) for 51–80% earn-ins, plus a separate Catch property deal requiring C$10 million over three years, signalling sustained funding for porphyry exploration and drilling contractors in the district.

Sigma Lithium’s share price jumped as much as 40% after it reported a 47% operating cash margin in Q4 2025, generating US$31 million in cash and cutting total debt by 35% to US$141 million. Two new offtake deals for high-grade lithium oxide concentrate from Grota do Cirilo cover 70,500 tonnes in 2026 worth US$96 million and 40,000 tonnes per year for three years worth US$50 million, with Q2 cash inflow projected to reach US$96 million. Following the January restart, Sigma plans a second plant to lift Grota do Cirilo capacity to 520,000 tonnes of concentrate per year by 2027.

Resolute Mining has signed a Memorandum of Understanding with Nimba Mining Company, a 100% Guinean state-owned entity, to co-develop gold projects in one of West Africa’s most prospective gold belts, under the oversight of Guinea’s Ministry of Mines and Geology. The partnership covers joint mineral resource assessment, detailed geological studies and frameworks for potential large-scale gold production, aligned with the State’s Simandou 2040 Programme. Resolute views Guinea as a candidate for its fourth mine, while NMC aims to increase local content in the national mining ecosystem.

Topping out of the five-storey MY Central office block marks a key milestone in Railpen and Socius’s £180m Mill Yard mixed-use campus on Devonshire Road, Cambridge, which will deliver 110,000 sq ft of flexible workspace, 70 build-to-rent apartments and a 2,100 sq ft nursery by 2027. Morgan Sindall Construction is targeting NABERS Design for Performance 5-star and BREEAM Outstanding ratings for the all-electric buildings, using its CarboniCa tool to pursue an embodied carbon saving of 5,013 tonnes and diverting 99% of waste from landfill. The scheme includes 1.55 acres of public green space with over 120 trees, green roofs, bat/bird/bee boxes, hedgehog habitats and a 280% biodiversity net gain target, plus a community pavilion by George King Architects, perimeter running track and secure cycle facilities.

McCann has secured a street lighting term service contract worth up to £18m with the London Borough of Hillingdon, covering an initial seven-year period extendable to twelve. The contract covers maintenance of around 25,000 assets, including 5,130 illuminated signs, bollards and centre island posts, 4,170 non‑illuminated signs and solar or reflective bollards, and 240 feeder pillars, plus full planned and reactive works. Scope includes column replacement, structural testing, cyclical electrical testing, night scouting and a 24‑hour emergency response, alongside wider highway-related works.

The Future Homes Hub has launched a cross-sector Water Smart Growth Board (WSGB) to coordinate integrated water management for new housing growth across England, linking developers, water companies and regulators. The WSGB will focus on aligning housing delivery with water resource constraints in stressed catchments, promoting measures such as higher water-efficiency standards in new homes and strategic SuDS deployment. For civil and geotechnical teams, the move signals closer scrutiny of drainage design, surface water attenuation and groundwater impacts at masterplanning stage.

The UK government’s commitment of at least £22bn to build eight carbon capture and storage (CCS) projects is largely focused on conventional amine-based post‑combustion systems, locking early schemes into high solvent regeneration energy and complex corrosion‑controlled plant. Concentrating funding on this single technology risks under‑investing in alternatives such as solid sorbents, oxy‑fuel combustion and direct air capture, which have different temperature windows, footprint requirements and integration options with existing industrial sites. For civil and process engineers, this narrows scope for optimising plant layouts, heat integration and long‑term retrofit flexibility across diverse emitters.

Metso has signed a major agreement to supply its VSF solvent extraction and electrowinning (SX-EW) technology to Southern Peru Copper Corporation’s Tia Maria greenfield project in Cocachacra, Arequipa. The SX-EW plant is designed to produce 120,000 t/y of high-purity copper cathode, using Metso’s modular VSF cells and integrated electrowinning circuits. For process and project engineers, the deal signals a commitment to heap leach–SX-EW flowsheets at Tia Maria rather than conventional concentrator–smelter routes.

Liebherr’s new 100 t R 9100 G8 mining excavator is moving into series production after pre‑series field validation and will replace the previous R 9100 G6 in the company’s 100 t class. The OEM is targeting the same deployment envelope as the G6 fleet while offering an updated eighth‑generation (G8) platform that standardises components with larger Liebherr mining excavators. For mine planners and maintenance teams, the key implication is a drop‑in successor for existing 100 t fleets with improved parts commonality and lifecycle support.
