Northumbrian Water is investing £4M in Northumberland to install a new 6.6km potable water main to reinforce its existing distribution network and reduce outage risk. The scheme will create additional connectivity between key service reservoirs and trunk mains, providing alternative supply routes during maintenance or bursts. Designers and contractors will need to manage long linear works, multiple road and utility crossings, and pressure management to integrate the new main without adversely affecting existing network hydraulics.

Delivering the annual Serpentine Pavilion in Hyde Park requires engineers to turn highly experimental, one-off architectural concepts into buildable, demountable structures within a few months, often using unconventional geometries and materials. Recent pavilions have used complex steel space frames, CNC-cut timber shells and fibre-reinforced polymer elements, all designed for rapid off-site fabrication, minimal foundations and tight tolerances on a small urban site. For practitioners, the programme acts as a live testbed for digital design-to-fabrication workflows, temporary works strategies and performance of novel materials at full scale.

Kier has secured a two-year extension on South West Water’s £140M Network Services Alliance contract, covering maintenance and upgrade works across the utility’s full operational region. The framework typically includes repair and replacement of trunk and distribution mains, pressure management assets and associated civils on live networks, requiring tight outage windows and complex traffic management. For contractors and suppliers, the deal signals continued demand for trenching, no-dig rehabilitation, pipeline condition assessment and rapid reinstatement materials in the South West water infrastructure market.

PfH Scotland has launched a £300M, four-year framework to procure civil engineering, consultancy, specialist surveys, low‑carbon technologies and major retrofit works for public sector decarbonisation programmes. The framework is structured into multiple lots covering fabric upgrades, M&E decarbonisation (including heat pumps, solar PV and battery storage), and whole‑building retrofit, with call‑off contracts available to councils, housing associations and other public bodies across Scotland. Contractors will need capability in PAS 2035/2038‑aligned retrofit design, complex occupied‑building phasing and performance monitoring to compete effectively.

Thames Water is investing more than £20M to upgrade ageing potable water infrastructure in Woodley, Berkshire, as part of what it calls its biggest network modernisation in 150 years. Works are expected to focus on replacing critical trunk mains and local distribution pipes, refurbishing valves and service connections, and improving resilience against leakage and low-pressure events. For civil and geotechnical contractors, the programme signals multi-year demand for trenching, pipe-laying, and streetworks in constrained urban corridors with tight traffic management and groundwater control requirements.

Marenica’s uranium resource in Namibia has been increased by 35% to 134.5 million tonnes at 180 ppm U3O8 for 52.8 million lb., giving Elevate Uranium a total Namibian inventory of 129 million lb. across Marenica and the 76.2-million-lb. Koppies project. The calcrete-hosted portion now accounts for 98.6 million tonnes and 38.6 million lb., defined from 3,874 mainly shallow RC holes totalling 89,850 m, with mineralisation thickening eastwards in a palaeochannel system. Elevate is running bulk samples through its Namibian pilot plant to validate its U-pgrade process, which bench tests suggest can pre-reject most waste and roughly halve processing costs.

Gen Z buyers are driving a rebound in US natural diamond demand, accounting for 23% of value while only 18% of the population, with average spend per purchase of $4,080 versus $2,250 for Baby Boomers and average stone sizes rising to 1.86 carats. De Beers’ data from 950 independent US jewellers show natural diamonds still command 85% of diamond jewellery sales value, despite lab-grown competition and total natural supply falling towards 90 million carats, the lowest since 1987. For Botswana, Angola, Namibia, South Africa and Lesotho, stabilising US demand and the Luanda Accord’s 1% rough-revenue marketing fund could support mine revenues and rough prices after several weak years.

Norsk Hydro has declared a second force majeure on aluminium sales after its 648,000‑tonnes‑per‑year Qatalum smelter in Qatar, jointly owned with Qatar Aluminum Manufacturing Co. (Qamco), terminated Hydro’s long-standing metal marketing agreement and said it will not deliver under existing contracts. The move follows war-related gas disruptions in March that forced Qatalum to shut down and later restart at only about 60% capacity, with the original force majeure still in place. Hydro now warns it may be unable to honour contractual deliveries even if operating conditions improve, adding fresh uncertainty to Western aluminium supply chains.

Triple Flag Precious Metals is paying $440 million in cash for a gold stream over Queensland’s Ravenswood open-pit mine, giving it rights to 5.5% of payable gold, stepping down to 3.75% after 194,200 oz and 2.5% after 253,000 oz, with deliveries priced at 10–20% of spot. The 8.6 Mtpa operation, owned by EMR Capital and Golden Energy and Resources, produced 134,000 oz in 2025 and is targeted to exceed 200,000 oz by 2028 following upgrades. The stream, covering 1,800 km² of exploration licences including Buck Reef West and Sarsfield-Nolans, lifts Triple Flag’s 2030 outlook to 150,000–160,000 GEOs.

China’s gold market cooled sharply in May as domestic gold ETFs saw RMB8.2 billion (£0.9bn) of net outflows, ending an eight‑month inflow streak, and Shanghai Gold Exchange withdrawals dropped to 64 tonnes, the weakest May since 2010. The Shanghai Gold Benchmark Price PM fell 2.7% versus a 1.4% decline in the LBMA Gold Price PM, with a stronger renminbi, buoyant Chinese equities and strained jewellery affordability all diverting capital from bullion. In contrast, the People’s Bank of China added 10 tonnes, lifting official reserves to 2,332 tonnes, while net gold imports reached 157 tonnes in April.

Hertha Metals will break ground this summer on a Conroe, Texas plant to produce 10,000 tonnes per year of high-purity iron for neodymium-iron-boron magnets, using its FLEXHERS (Flexible Fuel Hydrogen Electric Reduction Smelting) process that couples an electric arc furnace with natural gas or hydrogen. The startup already runs a one-tonne-per-day pilot using Minnesota ore and plans to scale to roughly 500,000 tonnes per year within four to five years, targeting both magnet and electrical steel markets. With 90% of current high-purity iron output in China and a US DoD ban on Chinese-origin rare earth magnets taking effect on 1 January 2027, the project directly targets a looming supply-chain gap.

Silver inventories at COMEX and London have fallen sharply from pandemic-era peaks – COMEX registered stocks are down more than 75% to about 79.9 million oz., while LBMA vaults hold 27,454 tonnes (≈883 million oz.), 20% below their 2021 record – yet analysts argue this does not prove a structural shortage. The World Silver Survey 2026 projects a 46.3 million oz. deficit and estimates 762 million oz. drawn from above-ground stocks since 2021, but CPM Group stresses that investment flows, working inventories and scrap – including “billions of ounces” in jewellery and electronics – can rapidly re-enter the market.

Europe’s critical minerals shortfall is framed by economic geologist Dr Nicholas Vafeas as a policy choice, with the EU funnelling roughly €380 billion per year into tightly scripted, mission-oriented R&D that favours climate and digital themes but leaves little room for speculative processing, refining and separation technologies. On a comparable $500 billion R&D spend, China files about 1.8 million patents—over 3,500 per $1 billion—buying “optionality” in areas like graphite processing, rare earth separation and lithium refining long before they became strategic. For miners and processors, the message is that control over midstream capabilities, not just new deposits, will define Europe’s leverage in future supply chains.

Depletion of high-grade deposits, declining ore grades and sustained high commodity prices are pushing miners towards frontier resources in the Arctic, on abyssal plains and eventually in space. Capital is already moving into Arctic projects targeting onshore and offshore deposits in ice-affected conditions, while proposed deep-sea mining of polymetallic nodules on abyssal plains faces an intensifying regulatory battle at the International Seabed Authority. Asteroid mining remains a long-dated, largely conceptual option, but is shaping early research into in-situ resource utilisation, autonomous extraction systems and ultra-remote operations.

The Corporate Associates Presidential Group of ISSMGE will run a dedicated panel at the 21st International Conference on Soil Mechanics and Geotechnical Engineering in Vienna in 2026, focusing on the future of geotechnical engineering practice. Industry leaders from major consulting firms, contractors and equipment suppliers are expected to address digital design workflows, advanced in situ testing, and risk allocation in large infrastructure projects. Outcomes are likely to influence updates to corporate design standards, procurement strategies and adoption of emerging investigation and monitoring technologies.

Researchers at UC Berkeley, funded by Yuba Water, have launched a Levee Digital Twin Platform for the Yuba River corridor, integrating continuous sensor data, geotechnical models and inspection records into an interactive system for levee condition assessment. The platform combines real-time pore pressure and deformation monitoring with historical performance data to flag anomalous behaviour along specific reaches and embankment sections. Engineers can use the tool to prioritise field investigations, refine seepage and stability analyses, and plan targeted remediation before high-flow events.

Codelco has signed a collaboration agreement with French research institute CEA-Liten (Laboratory for Innovation in New Energy Technologies and Nanomaterials) to develop technologies for electrifying underground mining fleets across its Chilean operations. The partnership will focus on powertrain electrification, high‑density battery systems and charging strategies suited to deep, high‑altitude block cave and panel cave mines, where ventilation demand and heat load are critical constraints. Outcomes are expected to inform future specifications for electric LHDs, trucks and support equipment, with direct implications for mine power distribution, ramp design and ventilation sizing.

Komatsu has opened a new Surface Haulage Headquarters and Customer Experience Center in Peoria, Illinois, consolidating engineering and support for its large mining truck and haulage product lines. The facility is positioned as a hub for surface mining haulage solutions, bringing together design, testing and customer interface functions that were previously distributed across multiple sites. A ceremonial tree planting at the opening signalled a focus on sustainable growth, with the campus intended to support future development of lower-emission haulage technologies.

FLSmidth has launched the KREBS® OSA, an online particle size analyser that measures particle size distribution continuously and in real time directly in the process stream, rather than via manual sampling and lab assays. Installed on the grinding circuit, the unit gives immediate feedback on mill and cyclone performance, allowing operators to adjust variables such as feed rate, water addition and classification cut size without waiting for batch results. For plant metallurgists, this supports tighter control of grind size, more stable circulating loads and reduced risk of off-spec flotation feed.

PYBAR, a Thiess company, has secured new underground development contracts at Southern Cross Gold’s Sunday Creek gold‑antimony project and Agnico Eagle’s Fosterville gold mine in Victoria, plus a contract extension at MMG’s Rosebery polymetallic mine in Tasmania. The work packages centre on decline and level development, ground support installation and associated services for high‑grade narrow‑vein orebodies, including gold‑antimony and zinc‑lead‑copper mineralisation. For geotechnical and mining teams, the awards signal continued demand for specialist underground contractors capable of managing complex ground conditions in mature brownfield mines and emerging critical minerals projects.

Hägglunds has introduced the CA280 radial piston hydraulic motor from Bosch Rexroth as a compact, high-torque drive for heavy-duty mining duties where envelope and mass are constrained, such as mobile crushers, apron feeders and belt drives. The CA280 extends the existing CA series architecture, retaining the same low-speed, high-torque behaviour and direct-drive capability while reducing overall package size compared with larger Hägglunds CB and CBM units. For designers, the motor targets retrofits on crowded structures and frames, enabling higher installed power without major steelwork or gearbox changes.

The New South Wales Government has allocated an extra $190 million in its state budget to upgrade Windsor Road at Rouse Hill, a key Western Sydney arterial currently carrying more than 30,000 motorists per day. The funding targets capacity and safety improvements on this constrained corridor, which links rapidly densifying residential areas to major centres such as Norwest and Parramatta. For civil and pavement engineers, the scale of spend signals upcoming design and construction packages involving lane additions, intersection upgrades and associated drainage and utility relocations.

Work has started on a 67-home affordable housing scheme on a 2.23-acre site in Sunbury-on-Thames, delivered by Chartway Partnerships Group in partnership with Metropolitan Thames Valley Housing (MTVH). The scheme will provide a mix of one to four-bedroom properties and forms part of MTVH’s programme to build around 1,000 new homes a year, adding to its existing stock of 57,000 homes for more than 120,000 residents. For contractors and consultants, the project signals continuing pipeline demand for medium-density residential schemes across Surrey and the wider South East.

Temporary works for the 7m-deep, triangular basement at 30 Marsh Wall in Canary Wharf are being delivered using Groundforce Shorco modular hydraulic props, supporting a secant piled wall and capping beam installed by Murphy Group on a highly confined site. Phase 1 uses five MP250 props up to 18.4m long, including 813mm-diameter extension tubes and remote load monitoring on the longest members, plus MP150 knee braces, all stiffness-matched to a Plaxis 3D model to meet tight deflection limits. Phase 2 adds four 6.3m-long MP375 raking props at 45°, each rated to 375 tonnes and fixed into 1,200mm-deep stub columns in the slab and capping beam, enabling progressive removal of flying shores as the concrete core and slabs advance.
