Oxford station upgrade: Trial holes drilled after complex utility diversions cause delays Trial holes are being carried out to inform the best route for complex utility diversions that have delayed Network Rail’s £161M project to revamp Oxford’s railway station. Network Rail and its contractors were forced to postpone the #replacement of the railway bridge over Botley Road – a key element of the station upgrade – this summer due to the complexity of #rerouting the #utilities. The #railwaycompany said that work to complete the #utilitiesdiversions could not be completed in time, “despite concerted effort by all organisations involved”. This included diversions of the mains #watersupply and sewer system. Thames Water is now excavating the trial holes along Botley Road on behalf of Kier Group – Network Rail’s principal contractor – that will collect information on the ground conditions and services below the road. Thames Water is expected to take five weeks to complete the work, which will take place on weekdays only. Since the summer, Network Rail has also been working with #stakeholders to try and secure agreement to identify alternative locations for the diversions of key utilities that serve #Oxford and #Oxfordshire. A Network Rail spokesperson said that there are “a number of challenges” with ground conditions and the subsurface at the site, the first being the quantity of utilities present beneath it. Another major challenge is a brick arch that was discovered underneath Botley Road in summer 2023, that was not previously recorded. The arch is believed to be #Victorian and was placed there to manage water levels. As such, the impact of removing it was unknown. On top of this, the area around Botley Road is prone to flooding due to the level of water table. An additional problem is that the ground conditions in the area are made up of Oxford #Clay, which historically presents challenges with construction projects due to its #soft and #porous nature. Following completion of the physical #trialhole works that will provide more information about the tricky ground conditions, Thames Water and Kier will require a further four weeks to validate the designs, cost, and programme to carry out the diversions. Preparation for the diversion of utilities, such as #water, #gas, #electricity and #broadband from under the road around the #bridge area began in November 2022. The Oxford Corridor Phase 2 project to upgrade the Oxford railway station will involve the construction of a new track, platform and accessible entrance on the west side of the station. The new #track and #platform will improve the safety of the line, create capacity for additional Oxford to Birmingham passenger services, and reduce journey times by up to two minutes.

Exciting times ahead as Barhale secures the coveted role to refurbish the historic £36m Northern Outfall Sewer (NOS)! An impressive project that channels the essence of Victorian engineering brilliance into the modern era. Originally crafted by Sir Joseph Bazalgette circa 1860, the NOS has been an unsung hero beneath London's bustling streets, efficiently managing a vast 300km³ catchment's wastewater. Its refurbishment is not just a nod to its heritage but an investment in London's future. Barhale's task is delicate and complex, with phased works designed to ensure uninterrupted flow for the sewer's 22,000 litres per second passage. And here's the clincher - no easy feat of over-pumping, but a strategy to maintain service while transforming the infrastructure with precision-engineered steel enhancements. Collaboration with Thames Water is key, plotting a course that sidesteps any disruption to the public. The Greenway footpath that overlays the pipeline will remain a tranquil passage for Londoners, reflecting Barhale's commitment to community and continuity. This isn't just maintenance; it's a meticulous modernisation promising another 120 years of service. And in the bustling heart of East London, as trains rumble and the city pulses, an extraordinary feat of engineering will unfurl unseen, securing the city's sanitation and setting a gold standard for urban infrastructure management. Expected to wrap up in summer 2027, this is indeed a venture that cements legacy while embracing innovation - a perfect blend of past and future. #Infrastructure #EngineeringExcellence #LondonSewerRefurb

Thames Tideway Tunnel: £4.5bn Super Sewer Begins Operation to Protect the River Thames After eight years of construction, the Thames Tideway Tunnel has officially started operations, with the first four of its 21 sites now activated. This £4.5bn project, also known as London’s "super sewer," is designed to tackle sewage pollution in the River Thames, which has long been an issue due to overflows from the city’s ageing sewer system. The tunnel, stretching 25km with a diameter of 7.2m, is built to intercept excess sewage and rainwater when the current system becomes overwhelmed. In its first 24 hours, the tunnel captured 589,000m³ of stormwater, preventing 219,000m³ of untreated sewage from entering the river, with the rest being managed by the existing Thames Water Lee Tunnel. Why This Matters: Environmental Impact: The tunnel reduces sewage pollution in the Thames, improving water quality and protecting aquatic life. Infrastructure Legacy: It complements Bazalgette’s 19th-century sewer system, which was originally constructed during the Great Stink, marking a major upgrade to London’s sewerage capacity. Collaborative Delivery: The project is being delivered by an alliance of top contractors, including BAM UK & Ireland, Morgan Sindall Infrastructure, Balfour Beatty plc, Ferrovial, Laing O'Rourke, Costain Group PLC, and VINCI. Full system integration is expected by 2025, and once completed, Thames Water will take over operations. The long-term benefit? A cleaner, healthier River Thames for Londoners and the environment.

Network Rail to recruit extra 400 drainage engineers Network Rail will channel £2.8bn of its total spend over the next five years into helping the railways better cope with extreme weather and climate change. The weather resilience programme will see Network Rail recruit almost 400 extra drainage engineers to increase the care and maintenance of its drainage assets to handle heavier rainfall. The infrastructure operator set out its plans to better cope with climate change as it entered its £43bn CP7 spending period yesterday. Network Rail will also ramp up investment in looking after thousands of miles of drains, cuttings and embankments promising a work boom for piling and groundworks firms. Plan to help combat major flooding like that in February near Rotherham in South Yorkshire. More than 20,000 cuttings and embankment will receive attention with over 300 miles being strengthened through renewal and refurbishment and over 900 miles seeing planned maintenance. More than 600,000 meters of drains will be built or rebuilt. Network Rail aims to improve remote digital monitoring, fitting more ‘smart’ movement sensors to cuttings and embankments to raise the alarm before a full landslip. The CP7 plan (at 2022/23 prices) for England, Wales and Scotland amounts to £42.8bn compared to £43bn in CP6. Network Rail said the spending plan would amount a 6% increase in regions’ expenditure between CP6 and CP7. Breakdown of £44bn CP7 spend: **£19.3bn on renewals (replacing old assets with new as well as investing in other capital expenditure to create a railway fit for the future e.g. digital signalling) **£12.6bn on maintenance (day-to-day upkeep of current assets) with regions spending 6% more on maintenance activity compared with CP6 **£5.3bn on support functions (things like safety & standards, timetabling, IT, HR) **£4.4bn on operations (things like signalling, stations, network controls) **£1.8bn ‘risk fund’ (a pot to be used as and when to cope with significant unforeseen events) Andrew Haines, chief executive, said: “Climate change is the biggest challenge our railway faces. The extreme weather of the past year that has seen an unprecedented 14 named storms, has taken its toll on our railway – with experts predicting more of the same to come. We are responding to that challenge with a huge investment in making our railway more resilient and better performing for rail users during such events. “We can never completely ‘weatherproof’ our railway, but we can be better prepared and mitigate the worst that Mother Nature throws at us, now, and into the future, to keep passengers and services safe and moving.

In the 19th and early 20th centuries, wooden pipes were a common solution for water distribution and sewage systems. These pipes were durable and relatively easy to install, made from hollowed-out logs, often of cedar or elm. Cities like Boston, New York, and Philadelphia relied on wooden pipes to support their growing populations. Philadelphia alone installed over 200,000 LF of wooden pipes by the early 1830s.| During this time, firefighting brigades faced the challenge of accessing water quickly during fires. They would dig down to the wooden water mains and use a hand auger to drill a hole into the pipe, allowing water to fill an earthen basin for use. After extinguishing the fire, they would seal the hole with a wooden plug, marking the spot for future use. This practice led to the term "fire plug." Did you know that Aaron Burr, better known for his infamous duel with Alexander Hamilton, founded New York City's first water system using wooden pipes? In 1799, Burr established the Manhattan Company to provide clean water to the city. However, a clause in the company's charter allowed it to use surplus capital for other purposes, which Burr cleverly used to start a bank. This bank eventually evolved into JPMorgan Chase, one of the largest financial institutions in the world. From a modern utilities infrastructure perspective, the use of wood for sewer and water pipes might seem odd, especially given advanced materials like HDPE and steel and ever-advancing slipforming techniques. Many wood pipes transported water reliably for over 100 years, a testament to the ingenuity and resourcefulness of early engineers. Their durability and longevity highlight a fascinating chapter in the history of urban infrastructure, showing that even seemingly primitive materials can stand the test of time. __ As Pursuit Managers for the civil infrastructure market, Mission Critical is the pivotal force behind companies winning their first CMGC, D-B, PD-B, P3, Federal and JOC pursuits.

🚧 Damaged and deteriorating bridges are a major concern when it comes to transportation infrastructures. Each year millions of dollars are spent on keeping these bridges structurally sound and functional. This is because bridge damage tends to be the result of multiple factors. These include exposure to harsh environmental conditions, variable loading and vibration, the presence of chlorides in de-icing salts, and more. Learn about 6 destructive and non-destructive methods for inspecting bridge damage and deterioration 👇 https://hubs.ly/Q02wTh9s0 #Bridge #ConcreteTechnology #Construction

After eight years, major construction work on London's £5bn super sewer is about to be completed. Known officially as the Thames Tideway Tunnel, it has been designed to reduce the amount of raw sewage that flows into the river. The 16 mile (25km) long pipe will divert 34 of the most polluting sewage outflows (CSO's) that have been discharging into the Thames. Critics say with climate change the tunnel may have a limited lifespan. "This is the moment we've all been waiting for," Andy Mitchell the CEO of Thames Tideway told BBC News from a boat above the tunnel on the Thames. "We're going to capture the vast, vast majority of the sewage that comes into the river and it will mean a cleaner river," he says. The final step is for a huge 1,200 tonne concrete lid to be lifted onto a shaft in east London. It's expected to take place sometime in the next few days. The first sewage is expected to flow into the tunnel this summer and it should be fully operational in 2025. Initially expected to cost £4.2bn, the tunnel has ending up costing about £5bn. That cost will be paid for by Thames Water customers over several decades with bills increasing by about £25 a year. The 7.2m (23ft) wide tunnel flows steadily downhill from Acton in west London to Abbey Mills in the east and during periods of sustained rainfall it will fill up with a mix of raw sewage and storm water. It can hold 600 Olympic sized swimming pools of liquid which will then be pumped to Europe's largest sewage treatment works at Beckton in east London. After testing over the summer the super sewer will be handed over to Thames Water. [BBC News] #engineering #thames #tideway #supersewer

Is the Government preparing to announce a privately-funded HS2 (High Speed Two) Ltd #Phase2a leg to Crewe? According to ‘rumblings’, HS2 may run from London Euston to Crewe, reinstating Phase 2a of the project, following a reversal of government policy. Currently no official confirmation from Government, but there is no question that this would be a positive and sensible decision regarding capital investment and infrastructure delivery - particularly interesting to note that it may be delivered by a private consortium. It is suggested that ministers have re-evaluated the cost-benefit analysis of HS2 and decided the railway should go beyond Birmingham. This probably won’t surprise anybody close to the programme, not least because it could play a key role in the government’s mission to rebuild Britain and grow the economy! #Infrastructure #FutureOfRail #CapitalInvestment #HS2 #Capacity #EconomicGrowth #Connectivity https://lnkd.in/eGWMiZRk
