Government plans to ban retention withholding in construction, cap payment terms from large firms to small suppliers at 60 days, and mandate late-payment interest at 8% above the Bank of England base rate written into contracts. The Small Business Commissioner would gain powers to investigate suspected poor payers, adjudicate disputes outside court, and levy “significant” fines in the tens of millions, plus force large companies to publish explanations for poor performance. Construction bodies, including the National Federation of Builders, are pushing for alternative performance mechanisms such as accessible surety bonds or insurance during the consultation on the retention ban’s implementation.

Plug-in balcony solar panels will go on sale in Lidl stores across Great Britain within months, following government moves to modernise regulations for “plug-and-play” devices that connect via a standard mains socket without formal installation. The UK is drawing on continental experience, where Germany alone adds around 500,000 such micro-PV units a year, to cut household grid demand and exposure to volatile fossil fuel prices linked to the Iran war and wider Middle East conflict. In parallel, the new Future Homes Standard will require most new low-rise homes to incorporate on-site renewable electricity generation, predominantly roof-mounted PV, alongside low-carbon heating such as heat pumps or heat networks.

Government plans to ban cash retentions in construction contracts aim to “prevent the abuse of retention payments in construction”, signalling a major shift in how risk and defects liability are managed across UK projects. The move would directly affect standard forms such as NEC and JCT, where 3–5% retentions are commonly withheld through practical completion and defects periods. Contractors and subcontractors could see significant changes to cashflow, security instruments (bonds, project bank accounts) and commercial negotiation of quality and defect-remedy provisions.

Per- and polyfluoroalkyl substances (PFAS) are shifting from a niche contamination issue to a core design constraint for water, wastewater and brownfield infrastructure, as regulators tighten limits on “forever chemicals” in soil and groundwater. Civil engineers are being pushed to integrate PFAS-specific measures such as high-pressure membrane treatment, granular activated carbon and specialised landfill liners into drainage, flood defence and remediation schemes. The trend signals more complex risk assessments, higher lifecycle costs and potential redesign of legacy assets where PFAS-impacted leachate or run-off was not previously considered.

Komatsu has run its 2026 North America Advanced Technician Competition at its Cartersville Customer Center in Georgia, putting 10 dealer-network diesel technicians through two days of scored tasks. Participants were evaluated on technical capability, quality of work and safety while working on Komatsu mining and construction equipment, mirroring field diagnostics and repair conditions. The event signals continued OEM emphasis on high-skill diesel maintenance as fleets integrate more complex hydraulics, electronics and emissions systems, with dealer technicians remaining critical to uptime and asset life.

HS2 Ltd has been instructed by the transport secretary to assess lower‑speed, simplified technical options for the high‑speed rail scheme, with claims that this could save “billions” of pounds and recover programme delays. Reducing design speeds from current high‑speed specifications would allow relaxation of some horizontal and vertical alignment constraints, potentially shortening tunnels, easing curve radii and reducing earthworks volumes. Any change would have direct implications for trackform design, slab track versus ballast choices, OLE configuration and geotechnical risk profiles along critical sections such as long cuttings and deep bored tunnels.

Construction of a 6km offshore breakwater with Europe’s deepest foundations is pushing marine geotechnical limits, with caissons and foundation elements installed in exceptionally deep water using heavy-lift vessels and precision positioning systems. Complex offsite fabrication of large concrete units, likely in a dedicated casting yard with slipform or match-cast techniques, is being coordinated with narrow marine weather windows and high-capacity barges to maintain programme. For designers and contractors, the project stresses accurate seabed characterisation, robust scour protection detailing and tight control of tolerances during submerged placement.

Waiting weeks for critical crusher and drill components due to fragile global supply chains is forcing mines into unplanned downtime that can cost hundreds of thousands of dollars per hour in lost production. MASPRO is pushing a reliability model based on locally manufactured, fully traceable wear parts and spares for primary crushers and production drills, with short lead times and stock held close to major Australian mining hubs. For maintenance and reliability engineers, the shift places new emphasis on inventory strategy, supplier proximity and verified component performance over lowest unit cost.

Queensland’s north-west copper sector is set for a major expansion as the State Government declares the proposed $2.3 billion Eva copper mine a prescribed project, fast-tracking approvals in the Mt Isa–Cloncurry district. The Eva project, owned by Copper Mountain (now part of Hudbay Minerals), is planned as a large-scale open-pit operation targeting multiple copper-gold deposits using conventional crush–grind–flotation processing. The decision signals strong backing for new sulphide concentrator capacity in an area already constrained by ageing infrastructure and long-haul concentrate logistics.

Panasonic’s latest TOUGHBOOK range is being deployed on Australian mine sites where devices must survive dust ingress, vibration and extreme temperatures that routinely destroy standard laptops. Units are tested to MIL-STD-810H and IP65–IP66 levels, with magnesium-alloy chassis, daylight-readable touchscreens usable with gloves, and hot-swappable batteries to support 12–20-hour field shifts. For geotechs, surveyors and maintenance crews, the key gain is reliable digital access to pit-wall monitoring, equipment diagnostics and mine-planning data directly at the face or on mobile plant.

Glencore has appointed industry veteran Peter Sharpe as chief executive officer of its Australian coal business, following the departure of previous head Ian Cribb. Sharpe will oversee a portfolio that includes large open-cut and underground operations in New South Wales and Queensland, supplying both thermal and metallurgical coal into export markets. The leadership change comes as Glencore navigates approvals, rehabilitation obligations and community pressure around its coal assets, including the proposed extension of the Glendell and Hunter Valley operations.

Macmahon has secured the mining services contract for the restart of the Mount Carlton gold mine in Queensland, signalling a move from care-and-maintenance back to full-scale open-pit and underground production. The scope is expected to cover drill-and-blast, load-and-haul and potentially underground development, requiring rapid recommissioning of mobile fleets, dewatering systems and ground support in previously inactive stopes. Geotechnical teams will need to reassess pit wall stability and underground conditions after the production hiatus, with updated monitoring and slope management plans before ramp-up.

Volvo Autonomous Solutions’ Volvo FH autonomous truck fleet at Brønnøy Kalk’s Velfjord limestone mine in Norway has expanded from a single shift to three shifts, now hauling all production from the pit to the crusher. The driverless trucks operate on a dedicated 5 km haul route through a tunnel to the processing plant, using GPS, lidar and radar for navigation and obstacle detection. For mine planners, the move signals growing confidence in fully autonomous, round-the-clock haulage on fixed routes with clearly defined geofences and traffic controls.

Top mining CEOs will convene in Peru for the World Mining Congress 2026 (WMC), bringing together senior decision-makers from across the global industry in a single venue. Confirmed participants include Iván Arriagada and other leaders from major international mining houses, signalling strong C‑suite engagement with the event’s technical and strategic agenda. For engineers and project managers, WMC 2026 is likely to be a key forum for announcements on capital allocation, technology adoption and long-term plans affecting project pipelines and supply chains.

Caterpillar has renewed its agreement with Fortescue’s Chichester Metals Ltd and FMG Solomon Pty Ltd to continue deploying Cat MineStar Command for hauling across three iron ore operations in Western Australia, including the Chichester Hub. The extension keeps Caterpillar’s autonomous haulage system integrated with Fortescue’s existing truck fleets and mine control infrastructure, rather than shifting to an alternative OEM platform. For mine planners and engineers, the deal signals continued standardisation around Cat’s autonomy stack for haul route design, traffic management and fleet productivity analytics at these sites.

A construction contract within the $85 million Wakehurst Parkway upgrade in New South Wales has been awarded to Ertech, with detailed design completed and physical works due to start mid‑year after site establishment in the coming months. The package is expected to focus on corridor capacity and flood‑related resilience improvements on this key arterial link between Seaforth and Narrabeen, where closures from heavy rainfall have historically disrupted traffic. Geotechnical and pavement engineers should anticipate substantial earthworks, drainage upgrades and pavement reconstruction under live‑traffic staging.

The National Transport Research Organisation is upgrading and expanding its fleet of pavement survey vehicles, with Chief Technology Officer Russell Gallagher leading several systems claimed as world firsts for the transport sector. The refreshed fleet integrates multi-sensor platforms on single vehicles, combining high-speed laser rut and texture measurement with continuous ground penetrating radar and high-resolution imaging. For asset owners, this enables network-level structural and surface condition data to be collected in fewer passes, improving calibration of pavement performance models and targeting of rehabilitation budgets.

Globe Metals and Mining is advancing the Kanyika niobium project in Malawi, aiming to challenge Brazil and Canada’s dominance in a market where niobium has no practical substitutes in high-strength low-alloy steels and advanced alloys. The project targets niobium and tantalum concentrates for use in micro-alloyed structural steels, gas pipelines and high-temperature turbine components, where small niobium additions (typically <0.1 per cent) deliver major strength and weldability gains. For miners and metallurgists, Kanyika signals emerging African supply that could reshape long-term offtake, pricing and risk strategies for niobium-dependent steel and superalloy producers.

Structural testing is presented as a non-negotiable step for mining infrastructure, validating the integrity and fatigue performance of critical assets such as conveyor gantries, processing plant platforms, and heavy-equipment support frames. Australian Mining Services (AMS) is cited using load testing, strain gauging and non-destructive examination on welded joints, bolted connections and high-stress nodes to detect cracking and deformation before service failures occur. For engineers, the message is to embed scheduled structural testing into lifecycle management, particularly where dynamic loads, corrosion, and vibration govern design behaviour.

The re-election of the South Australian Labor Government has cleared the political path for long-delayed mining reforms, with industry leaders pressing for streamlined approvals under the Mining Act and faster processing of Program for Environment Protection and Rehabilitation (PEPR) submissions. Key priorities include reducing multi-year lead times for greenfield copper and critical minerals projects in regions such as the Gawler Craton and Coober Pedy, and improving coordination between state planning, native title negotiations and environmental regulation. For geotechnical and mine planners, any statutory time limits or clearer PEPR requirements could materially change front-end study schedules and risk allocation in feasibility work.

Caterpillar has renewed its agreement with Fortescue to continue deploying Cat MineStar Command autonomous haulage and drilling systems across the miner’s Pilbara iron ore operations. The deal extends support for existing autonomous truck fleets and remote operations centres while enabling further integration of fleet management, high-precision guidance and collision avoidance on Caterpillar 793 and 789-class haul trucks. For geotechnical and mine planners, the expanded automation framework means tighter control of haul profiles, bench geometry and traffic interactions, with data streams feeding back into pit design and road maintenance strategies.

CAPS Australia is deploying modular nitrogen generators and compressed air systems from global OEM partners to support underground mining maintenance in Australian operations. The skid-mounted nitrogen units are engineered to match site-specific pressure, purity and flow requirements for tasks such as tyre inflation, longwall equipment servicing and inerting, reducing reliance on delivered gas cylinders. For mine operators, the key shift is towards on-site, containerised utilities that can be scaled or relocated between declines and workshops as production layouts change.

Mac’s Truck Rental has supplied a 32‑tonne Volvo FMX 8×2 low‑profile beavertail on long‑term hire to X‑Hire Platforms, its first Volvo FMX chassis, selected for higher payload capacity and durability across mixed-access construction sites. Over the past year Mac’s Truck Sales has also delivered 12 DAF trucks to Eagle Plant Hire, including four new DAF XF 480 32‑tonne 8×2 rigid crane trucks with Fassi F710RA.2.26 cranes and DAF XD450 26‑tonne 6×2 flatbeds with Fassi F545RA.2.25 cranes, all with twist‑lock layouts engineered in‑house to secure 10–32 ft cabins and welfare units.

McLaughlin & Harvey has secured an £87.7m contract from Caledonian Maritime Assets Limited for a £107m redevelopment of Port Ellen Ferry Terminal on Islay, including major land reclamation to expand marshalling and laydown areas and construction of a new dedicated ferry berth with dredging, fendering and upgraded bollards. The scheme adds a new linkspan, fixed ramp, shore power charging, a larger terminal building, and a substantially extended commercial quay roughly four times the current length, plus a longer fishing berth with segregated offloading zones. Works start June 2024 after Fèis Ìle and run to 2029, supporting operation of two new Islay-class ferries and upgraded active travel and vehicle-charging facilities.
