Wall-climbing robots from a Birmingham-based firm have completed non-destructive testing on a 200m-tall reinforced concrete chimney at an EDF facility, proving they can adhere and manoeuvre on near-vertical surfaces at height. The trials focused on remote NDT data capture on the external shell, replacing rope-access technicians for ultrasonic and visual inspection passes over large areas in a single deployment. For asset managers, the approach points to faster condition assessments, reduced working-at-height exposure, and more frequent monitoring of tall stacks and cooling structures.

A rival Liverpool Street station redevelopment concept has been unveiled, with its architect claiming it can be delivered for around half the cost and in roughly half the construction time of Network Rail’s current scheme, while requiring significantly less demolition. The alternative proposal is understood to retain more of the existing station fabric and over-site structures, reducing structural interventions and associated temporary works. For contractors and designers, the approach signals potential for lower programme risk, fewer possessions and reduced disruption to deep foundations and adjacent assets.

Rail freight and passenger operators warn that the proposed Great British Railways (GBR) structure could “mark its own homework”, with the infrastructure manager, system operator and contracting authority concentrated in a single body rather than separated between Network Rail, ORR and DfT. Stakeholders fear this blurring of roles will weaken independent economic regulation of track access charges and capacity allocation on key freight corridors such as Felixstowe–Nuneaton. Concerns also centre on deterring international investment in rolling stock and terminals, where long-term concessions and predictable regulatory frameworks are critical.

Approval of a new underground exploration tunnel at Southern Cross Gold’s Sunday Creek antimony–gold project in central Victoria will allow drilling from underground rather than surface pads, targeting high‑grade shoots at depth while reducing disturbance to farmland and native vegetation. The tunnel will be driven from freehold land into the main mineralised corridor, enabling tighter drill spacing and improved structural definition of the orogenic system. For geotechs and mine planners, the shift to underground drilling will refine resource geometry, de‑risk future decline design and inform ground support regimes early.

Building products manufacturer Marshalls has parted company with chief executive Matt Pullen with immediate effect, less than two years after his January 2024 appointment, following half-year results showing operating profit down 37% and pre-tax profit down 46% despite a 4% revenue increase. Chief commercial officer Simon Bourne becomes interim CEO while the board begins an external search for a permanent replacement. Chair Vanda Murray signalled a push to “refocus” and accelerate the Transform & Grow strategy, indicating likely scrutiny of product mix, margins and capital allocation on future schemes.

HE Services (Plant Hire) has placed a £25m order with Marubeni-Komatsu for more than 250 excavators ranging from 1.5-tonne minis to 49-tonne machines, in one of the largest fleet upgrades in the company’s history. The staged deliveries, running into next year, will refresh assets across 11 depots including Ashford, Cardiff, Durham and Daventry, targeting higher performance, reliability and operator comfort on hire. Contractors can expect newer Tier-compliant kit and greater availability for earthworks, utilities and infrastructure jobs across the UK.

National Timber Group, the UK’s largest independent timber distribution and processing group with 47 sites and 1,150 staff, has entered administration, with Alvarez & Marsal appointed on 26 November 2025 and an accelerated sale process launched. Administrators have made 561 immediate redundancies, closed 13 branches and mothballed some production facilities, while other depots continue trading under brands including Thornbridge, Arnold Laver, Rembrand Timber and Norclad. Contractors, joinery shops and house-builders reliant on NTG’s structural timber, sheet materials and engineered products face short‑term supply disruption and potential regional gaps in merchant coverage.

McLaren Construction has been appointed main contractor for Global Holdings’ 100,000 sq ft Xylo office in Clerkenwell, billed as the UK’s largest all-timber frame commercial building and costed at about £57m. The nine-storey structure will use glulam beams and cross-laminated timber supplied by Hybrid Structures to store more than 2,400 tonnes of CO₂, targeting embodied carbon 50% below a typical London office and operational emissions cuts of up to 82%. Designed for LETI Pioneer, NABERS UK 5.5-star and BREEAM ‘Excellent’, completion is scheduled for Q2 2028.

Excellon Resources is targeting deeper gold-silver mineralisation at the past-producing Mallay underground mine in Peru, where historical output focused on silver-lead-zinc veins. A new technical report outlines potential at depth below existing workings and along strike of the Mallay and Manto Santa Elena structures, supporting a possible restart scenario. For mine planners and geotechs, the shift to deeper targets implies renewed underground development, updated ground control in previously mined areas, and re-evaluation of shaft, hoisting, and ventilation capacity for a gold-silver focused operation.

Karnalyte Resources is promoting a proposed 70‑year potash operation 175 km east of Saskatoon, designed to produce 2.2 million tonnes of potash and 104,000 tonnes of hydromagnesite annually. The long mine life and dual‑product output signal a large, stable brine and ore resource, with implications for long‑term tailings, brine management and process plant design. For contractors and consultants, the scale suggests sustained demand for solution mining expertise, evaporation pond or crystalliser design, and associated rail and bulk handling infrastructure.

Dundee Precious Metals’ latest study for its Serbian gold project forecasts average annual production of 148,000 oz of gold, signalling a mid-scale operation in regional terms. The updated plan will drive mine design, processing plant sizing and tailings storage requirements, with knock-on effects for pit slope optimisation, haul road geometry and water management. Contractors and consultants can expect demand for detailed geotechnical investigation, open-pit stability analysis and materials handling design aligned with this throughput profile.

Centerra Gold has taken a 9.9% equity stake in Canadian explorer Metal Energy, matching similar 9.9% positions it has built in several other Canadian juniors over the past year. The move signals continued interest in early‑stage exploration exposure without triggering takeover bid thresholds common in Canadian securities rules. For geotechnical and mining teams, the backing of a mid-tier producer may accelerate drilling, resource definition and geotechnical characterisation on Metal Energy’s projects, potentially bringing new nickel or base‑metal targets forward in the development pipeline.

Panama will release the first audit results on First Quantum Minerals’ Cobre Panama copper mine in December, with initial reports expected as early as next week as the government weighs whether operations can restart. The review covers compliance with the 20-year concession contract, environmental obligations in the Donoso and Omar Torrijos districts, and fiscal terms linked to the mine’s reported multi-billion-dollar investment. Outcomes will directly affect one of Central America’s largest open-pit copper operations and contractors tied to associated port, power and tailings infrastructure.

Guardian Metals is advancing a pre-feasibility study at its Pilot Mountain tungsten project in Nevada, targeting completion in the first half of next year as it positions the historic district for a potential restart. The work is expected to refine open-pit and underground mine designs, update JORC-compliant resource estimates for tungsten, copper and silver, and optimise processing flowsheets for scheelite and wolframite concentrates. For geotechnical and mine planners, the PFS will be critical for pit slope parameters, underground ground support regimes and tailings storage options in an arid, seismically active setting.

A feasibility study for the Wynyard potash deposit in Saskatchewan confirms a 70‑year mine life with positive project economics, positioning the operation for long-term, stable returns. The assessment indicates sufficient ore reserves and process design robustness to sustain multi-decade production, with infrastructure and mine planning structured around extended shaft, hoisting and processing plant utilisation. For engineers, the long horizon implies emphasis on durable ground support, staged tailings and brine management, and flexible materials handling systems that can accommodate evolving extraction sequences over several decades.

Australia’s net zero pathway is putting pressure on contractors to cut embodied carbon from construction, which currently contributes about 10 per cent of national emissions, with interim targets of a 43 per cent reduction from 2005 levels by 2030 and net zero by 2050. Coates points to practical site measures such as switching to electric or hybrid plant where feasible, right‑sizing temporary equipment fleets, and using low‑carbon fuels. For civil and infrastructure projects, early planning of plant utilisation and temporary works can materially reduce both fuel burn and upfront Scope 3 emissions.

Rangers Football Club has commissioned a wide‑ranging feasibility study to examine redevelopment options for the 50,817‑capacity Ibrox Stadium in Glasgow, a Category 4 UEFA venue with a 190,000m² site footprint. Consultants are expected to assess structural upgrades to the existing bowl, potential expansion of spectator capacity within current urban constraints, and modernisation of concourses, access routes and hospitality areas. Any scheme will need to address ageing reinforced concrete elements, crowd flow under current safety regulations, and construction phasing to maintain matchday operations.

Construction has started on a long‑planned south Dublin link road intended to ease chronic congestion in a major suburban employment and residential hub. Contractor Bam is delivering the scheme, which will connect existing arterial routes to create an alternative corridor to heavily loaded local streets and junctions. For civil and geotechnical teams, key issues will include working within a dense urban environment, managing traffic during phased tie‑ins, and coordinating utilities diversions around live commercial and housing developments.

Construction of SSEN Transmission’s high-voltage subsea electricity link between Orkney and mainland Britain has passed its first year, with the scheme now shifting from enabling works to full delivery. Key milestones include completion of major onshore civil works for converter station sites and substantial progress on landfall infrastructure to receive the subsea cable. SSEN reports early local economic gains through Orkney-based contractors and supply-chain participation, signalling ongoing demand for marine civils, HDD landfalls and grid-connection geotechnical works in a challenging coastal environment.

Infrastructure is framed as the essential backbone of modern civilisation, with the author contrasting current built systems against a hypothetical world without treated water, roads, railways, schools, hospitals or electric power. The piece links long-term human wellbeing to decisions now on how we design and deliver assets such as heating and cooling networks, transport corridors and water treatment plants. For engineers, it signals continued pressure to integrate resilience, low‑carbon materials and whole‑life performance into everyday project choices rather than treating them as add‑ons.

Strabag, Arup and partners have secured major construction and design packages for the 2.2km Fehmarn Sound immersed tunnel, the inland section linking Germany’s road and rail network to the Fehmarnbelt Fixed Link. The new tunnel will replace the existing Fehmarn Sound Bridge, removing a key capacity and clearance constraint on the corridor between Puttgarden and Denmark. For geotechnical and structural teams, the award signals imminent detailed design on immersed-tube foundations, marine-ground interfaces and transition structures tying into the main Fehmarnbelt tunnel.

Budget 2025 commits the UK to expanding nuclear generation capacity while legislating to end oil extraction in the North Sea, signalling a structural shift in long-term energy infrastructure investment. New nuclear build and life-extension of existing stations will drive demand for large-scale civil works, including deep excavations, high-spec reinforced concrete containment structures and upgraded grid connections. Decommissioning of offshore oil assets will accelerate requirements for subsea plugging and abandonment, platform removal and repurposing of existing jackets and pipelines for carbon capture and storage or offshore wind.

Government backing for major schemes in the Autumn Budget has drawn a broadly positive response from the UK construction and infrastructure sector, which sees it as confirmation that capital projects remain central to the growth strategy. Industry bodies are focusing on delivery of large, long-term programmes such as rail upgrades, strategic road improvements and energy transition infrastructure, where multi‑year funding certainty is critical for contractor pipelines. For engineers, the key issue will be how quickly budget commitments translate into procurements, site mobilisation and resolved planning risk.

Chancellor Rachel Reeves’ 2025 Budget confirms government backing for major UK transport schemes, including the Lower Thames Crossing, Docklands Light Railway (DLR) extensions and new rail connections. Support for the Lower Thames Crossing signals continued commitment to a new Thames road tunnel and approach roads east of London, intended to relieve the heavily loaded Dartford Crossing and M25. Funding clarity for DLR and rail links gives promoters confidence to progress statutory processes, detailed design and ground investigations.
