Near 50% more UK construction firms are on the brink, with Begbies Traynor’s Red Flag Alert reporting 9,981 companies in ‘critical’ distress in Q4 2025 (up 46.1% year-on-year) and 108,213 in ‘significant’ distress (up 10.9%). The worst-hit segments include ‘Development of building projects’ (14,968 firms, +12.7%), ‘Construction of Domestic Buildings’ (12,121, +9.9%) and ‘Specialised design services’ (6,666, +15%), alongside sharp rises in electrical and MEP trades. BTG warns stalled projects, high input costs and HMRC tax enforcement are squeezing cash flow, raising counterparty and supply-chain risk.

Clancy has begun a £10m Thames Water mains renewal in Haringey, replacing more than 8km of ageing distribution pipes across 29 streets over a two‑year programme. Initial works in February focus on The Broadway, Crouch Hill, Ridge Road and Oakington Way, targeting an area that has suffered multiple main bursts and supply interruptions in recent years. For civil and utility engineers, the scheme signals continued investment in network resilience and leakage reduction on older urban assets, with close coordination promised with Haringey Council to minimise traffic and resident disruption.

At least 200 artisanal miners are reported dead after multiple shallow coltan mine shafts collapsed at the Rubaya mining complex in North Kivu, eastern Democratic Republic of the Congo, following heavy rainfall. Local authorities say informal pits on steep, highly weathered slopes failed almost simultaneously, with narrow unsupported stopes and adits giving miners little chance to escape. The incident again exposes the absence of geotechnical design, ground support, drainage control and regulated access in rebel-held artisanal coltan operations across the region.

NRW Holdings has secured a bulk earthworks contract from Rio Tinto for the West Angelas Sustaining Project in Western Australia, covering access development to five new satellite iron ore pits. The scope includes construction of haul roads, pit access corridors and associated earth platforms to integrate the new pits into the existing West Angelas operations. For geotechnical and civil teams, the work will centre on large-scale cut‑and‑fill in Pilbara bedrock and regolith, haul road geometry for ultra-class trucks, and tie-ins to established drainage and mine infrastructure.

PYBAR’s Raise Bore Division has mobilised to BHP’s Prominent Hill copper-gold mine, 650 km northwest of Adelaide, to construct multiple ventilation raises and inclined ore passes linking the Malu orebody to the new Wira Shaft. The raiseboring programme follows an “innovative study” phase and is aimed at improving ore flow geometry and airflow paths into the shaft infrastructure. Geotechnical and mine planning teams will need to integrate new raise locations with existing stopes and development to manage stability, dilution and long-term ground support demands.

Australian Droid + Robot has formed a strategic collaboration with Intel to integrate Intel edge computing hardware into its Explora XL rugged underground robotics platform, targeting deep and inaccessible mine workings. The upgraded Explora XL is designed to process LiDAR, video and sensor data on-board rather than via surface links, enabling faster mapping, inspection and decision-making in areas with poor communications. For geotechnical and operations teams, this supports remote stope and drive inspections, ground-condition assessment and re-entry checks without exposing personnel to unsupported ground or irrespirable atmospheres.

E-LIX™, the chloride-based hydrometallurgical process developed by electrochemist Dr Eva Lain in 2014, is progressing from lab concept to commercial deployment as a standalone alternative to conventional smelting for copper and polymetallic concentrates. The process operates at atmospheric pressure and relatively low temperatures, using selective leaching and electrowinning to treat high-arsenic and complex feeds that are difficult to place in traditional smelters. For mine developers, E-LIX™ offers a potential on-site refining route that could reduce concentrate transport, simplify arsenic management and change project flowsheet assumptions.

Engineers Collective’s latest podcast episode marks the 200th anniversary of the Menai Suspension Bridge, Thomas Telford’s pioneering 19th‑century crossing between mainland Wales and Anglesey. The discussion revisits its original wrought‑iron chain design, 176m main span and circa 30m clearance for shipping, and the challenges of constructing masonry towers and anchorages in a high‑tidal, exposed strait. Guests explore how subsequent strengthening, deck replacement and traffic loading upgrades inform current practice in long‑span bridge assessment, heritage conservation and asset management.

Spey Viaduct’s collapsed spans over the River Spey will be cut and lifted out in sections under a Moray Council plan to create safe access for structural and geotechnical investigation following the 14 December failure. The segmented removal will allow close inspection of critical elements such as bearings, pier foundations and connection details that are currently submerged or unstable in the river channel. Findings are expected to inform both the viaduct’s future and any revisions to inspection and scour management regimes on similar river crossings.

Gold built Victoria’s mining legacy, but the state is now targeting a new wave of critical minerals including rare earths, lithium and high‑purity alumina alongside its established gold sector. Exploration is intensifying in the Bendigo and Stawell zones, with juniors and majors using deeper diamond drilling and modern geophysics to chase structurally controlled deposits beneath historic workings. For geotechs and mine planners, the shift means more complex underground designs in highly altered host rocks and greater emphasis on tailings reprocessing, acid‑forming potential and multi‑commodity processing flowsheets.

Rio Tinto has strengthened its share structure as major institutional investors signal support for a potential merger with Glencore, positioning the combined group as a dominant player in iron ore, copper and aluminium. A deal would consolidate Rio’s Pilbara iron ore system and Oyu Tolgoi copper interests with Glencore’s large thermal coal, cobalt and zinc portfolios, concentrating ownership of several Tier 1 orebodies. For geotechnical and mining engineers, such consolidation could accelerate portfolio-level decisions on mine life extensions, brownfield expansions and closure schedules across multiple continents.

The Minerals Council of Australia is pushing for a Victorian mining growth plan centred on school outreach, TAFE pathways and university places in geoscience, metallurgy and mining engineering, alongside faster permitting. Recommendations include streamlining approvals under the Mineral Resources (Sustainable Development) Act, expanding regional training hubs near centres such as Bendigo and Ballarat, and aligning curricula with mine automation and critical minerals processing. For operators, the agenda signals potential relief on project lead times but also a need to engage earlier with education providers to secure skilled labour.

SLR Consulting’s mining sector lead for Africa and the Middle East, Angus Bracken, argues that sustainability decisions must be based on integrated insight across the full value chain, from conceptual scoping through operations to closure. He points to linking mine design, tailings and waste rock strategies, water and energy balances, and closure landforms in a single decision framework, rather than treating ESG, permitting and technical studies as separate workstreams. For engineers, this means earlier trade-off studies on haul profiles, processing routes and residue storage options to avoid costly redesign late in the project cycle.

Zoomlion is developing a wide-body battery trolley haul truck option that builds on the recent resurgence of trolley-assist systems at large open pits such as Collahuasi and Los Pelambres, which currently rely on diesel-electric trucks. The concept targets battery-electric trucks drawing power from overhead catenary on uphill hauls, using on-board batteries for off-trolley sections to cut diesel use and ramp emissions. For mine planners, this points to future pit designs and ramp geometries explicitly optimised for mixed catenary–battery operation rather than pure diesel haulage.

Codelco and Schneider Electric have signed a memorandum of understanding to form a strategic alliance focused on digital transformation and energy efficiency across Codelco’s mining operations. The framework targets co-development and deployment of advanced automation, power management and data-driven optimisation solutions, likely integrating Schneider’s EcoStruxure platforms with Codelco’s existing process control and electrical systems. For mine operators, the move signals more systematic use of real-time energy monitoring, load management and process digitalisation to cut operating costs and emissions intensity at large-scale copper assets.

Trafo Power Solutions has designed and supplied a skid‑mounted mobile substation for an Australian mine, providing a transformer and associated switchgear on a single transportable base for rapid deployment. Managing Director David Claassen says the in‑house engineered unit is built for harsh mining conditions, with a robust steel skid, integrated cooling and protection systems, and plug‑and‑play terminations to minimise on‑site installation time. The solution allows the mine to relocate power infrastructure as pits advance, reducing civil works and downtime during reconfiguration.

The $148.8 million Mandurah Estuary Bridge Duplication has opened its new westbound carriageway to traffic, easing pressure on the existing bridge that currently carries more than 33,000 vehicles per day between southern Mandurah and the city centre. The project adds a parallel structure across the estuary, effectively doubling lane capacity on this key north–south coastal route in Western Australia. Remaining works will focus on completing the eastbound duplication, tie-ins and approach road upgrades, which will influence future traffic loading, maintenance access and estuary-side geotechnical performance.

More than one million trips have already been made through Victoria’s West Gate Tunnel since opening in December, with over 20 per cent of journeys by trucks diverting heavy vehicles away from inner‑west residential streets. The twin tunnels and new links to the Port of Melbourne, central city and CityLink are easing congestion in suburbs such as Footscray, where arterial corridors previously carried high freight volumes. For civil and traffic engineers, early usage data will inform ramp metering, pavement performance monitoring and future freight route planning across Melbourne’s west.

Australasian Railway Association has issued new recommendations on how federal financial support should be structured for state and territory rail infrastructure, linking funding models to measurable growth in revenue, jobs and wider economic output. The submission calls for more predictable, long‑term Commonwealth commitments to multi‑year rail programmes, rather than ad‑hoc project grants, to stabilise supply chains and specialist labour. For engineers and contractors, the proposals signal a push towards larger, programmatic rail packages and clearer investment pipelines for works such as Inland Rail sections and station precinct upgrades.

The SMP Alliance has released a “legacy and learnings” report detailing how its alliancing model delivered smart motorway upgrades and retrofit emergency areas amid major programme disruption and scope change. The report covers collaborative planning between National Highways, designers and contractors, rapid redesign of refuge areas and technology systems after the 2023 smart motorway cancellations, and re‑sequencing works under live traffic. For practitioners, it sets out practical lessons on risk‑sharing, integrated control centres, and standardised design packages to keep lane closures and possession durations to a minimum.

The government’s £45bn Northern Powerhouse Rail (NPR) pledge is facing scepticism from opposition MPs, with the scheme branded “castle-in-the-air planning” amid a lack of detailed route, phasing or funding breakdown. Transport secretary Heidi Alexander insists the Department for Transport has absorbed HS2 lessons on cost escalation, land acquisition and phased delivery, signalling tighter cost controls and earlier constructability input for new high-speed and upgraded corridors. For civil and rail engineers, the key uncertainty is how NPR’s scope will balance new-build alignments with upgrades to existing trans-Pennine routes.

Anglian Water has opened procurement for a £1.5bn major projects framework covering AMP8 design-and-build works to cut pollution and upgrade water and wastewater assets across eastern England. The multi-lot framework will target schemes such as storm overflow upgrades, new or expanded treatment works and network resilience projects, with packages expected to span civils, MEICA and process engineering. Contractors will need strong track records in regulatory compliance for water quality and environmental permits, plus capacity to deliver large, multi-site programmes under tight outage and consent constraints.

Biodiversity net gain requirements on Nationally Significant Infrastructure Projects are being framed as a source of “desperately needed” long-term climate resilience, with large linear schemes such as new highways, rail corridors and strategic energy infrastructure able to create continuous habitat networks at scale. Experts point to legally secured 30‑year management plans, species-rich grassland and woodland planting, and restored wetlands as measures that can buffer flood risk, reduce heat stress and stabilise soils around major assets. For designers and contractors, this shifts BNG from a planning obligation to a core part of geotechnical and drainage resilience strategy.

Australia’s Federal Government has released an Australian Critical Minerals Prospectus detailing 49 mining projects and 29 midstream processing proposals across commodities such as lithium, rare earths and high-purity alumina. The prospectus is aimed at attracting offshore capital into upstream deposits and midstream plants, including projects like Iluka Resources’ Eneabba monazite operation in Western Australia, to build domestic separation, refining and value-adding capacity. For engineers and project developers, the document signals a pipeline of greenfield and brownfield work spanning mine development, concentrators and chemical processing infrastructure.
