The Canal & River Trust has put in place long term framework contracts for #ground investigation and #technical #engineering and #design services to help with #asset management in the face of #climate change. Waterways charity the Canal & River Trust cares for 3,200km of #canals and #river navigations across #England & #Wales. It also owns a large number of listed #structures and manages 1,579 locks, 55 #tunnels, 2,969 #bridges, 279 aqueducts and 71 reservoirs. Most of the canal network’s earth-built structures are more than two centuries old. The Canal & River Trust is thus seeking to understand how climate change is impacting the canal network, while aiming to future-proof its assets. It has opted for specialist #technical frameworks to help look after its reservoirs, embankments, cuttings and other structures. The trust’s in-house team will be able to call for support from Arcadis (UK), RSK Environment and Geotechnical Engineering Limited (GEL) for its programme of ground #investigations. The works will help establish the integrity of the canal network assets, assess potential #contamination, and monitor potential ground movement of canal structures or groundwater levels. The Canal & River Trust has also set up a technical engineering and design services framework with Arcadis (UK), PELL FRISCHMANN CONSULTANTS LIMITED and Stantec UK. The three consultants will support the trust during planning works required to keep the canal network open and safe. Canal & River Trust chief #infrastructure and programmes officer Malcolm Horne said: “The UK’s canal network is a fantastic example of long-lasting #civilengineering, living heritage that is still in active use today. This 250 year old network is also facing the impact of a challenging, changing climate, with the multiple storms in the past few months alone causing millions of pounds of damage. “To keep our canals safe and available for years to come, we must make sure our historic structures are sound, and that we’re planning our works with the best possible knowledge, both from our in-house expertise and drawing on the latest advances from other industries.” The charity is moving from a single to multi-supplier model for its professional service and #geotechnical inspection contracts from 1 April onwards. According to the trust, this will increase resilience for the delivery of #projects, and it will be able to access a wider range of #innovation, best practice options, technical and #sustainable solutions. The new contracts are awarded following a five-stage tender process carried out over 18 months. They are for a period of up to eight years, with an initial term of four years.

The recent incident has reignited discussions within the geotechnical industry regarding the inherent risks associated with trench or excavation work on construction sites. It serves as a stark reminder of the potentially catastrophic consequences of collapses and underscores the critical importance of prioritizing safety measures to protect personnel. This event prompts a necessary reflection on current safety protocols and highlights the need for continuous improvement in risk assessment, training, and implementation of preventative measures. As the industry grapples with this sobering reality, it is imperative that stakeholders collaborate to identify and address systemic challenges, embracing innovative technologies and best practices to ensure the safety and well-being of all individuals involved in trench and excavation operations. www.alphasafety.co.uk

"Precision and resilience: Overcoming the challenges of offshore pile driving to build the foundations of tomorrow's marine infrastructure." Failure in offshore pile driving occurs due to geotechnical challenges, equipment issues, environmental factors, design errors, and operational mistakes. Soil variability and resistance can hinder pile stability, while hammer malfunctions and pile defects compromise integrity. Dynamic ocean forces and adverse weather conditions affect accuracy and alignment. Incorrect pile selection and inadequate site assessments lead to unforeseen challenges. Poor installation techniques and lack of real-time monitoring further exacerbate issues. Mitigation strategies include comprehensive geotechnical surveys, robust design and planning, using quality equipment, regular inspections, employing skilled personnel, providing ongoing training, and implementing real-time monitoring systems. These measures help reduce risks, ensuring the safety and success of marine construction projects. video rights : Respective owners DM for removal/credits #piling #engineering #civilengineering #marine #piledriving #construction #civilconstruction #engenharia #engenhariacivil

TECHNICAL PAPER | The design and management of groundwater control for the construction of a railway box culvert By George French, OGI Groundwater Specialists Ltd (Cooling Prize Finalist 2023) Rochdale and Littleborough are communities in Greater Manchester that are at risk of significant flooding events, with several such events occurring in the past 20 years (Environment Agency, 2009). As a consequence, the River Roch, Rochdale and Littleborough Flood Risk Management project has been set up in partnership between the Environment Agency and Rochdale Borough Council to improve the infrastructure necessary to reduce the risk of flooding in the future. Part of the scheme involves the construction of two large attenuation reservoirs in Gale, Littleborough, that collect and store river water from the River Roch and nearby tributaries during storm events. For river water to reach the attenuation lagoon on the west side of the railway line, the construction of a culvert was required beneath the Network Rail Calder Valley Railway Line. The Calder Valley Railway Line is a busy line, with passenger and freight trains travelling between Manchester and Leeds, passing at least every 15 minutes. The culvert construction required a four day rail blockade during which the track was removed, the ground excavated, the culvert installed and the railway line reinstated. Due to the strict four day blockade for the completion of the main works, there was no time available for design modifications once the construction works commenced. Hence, a robust and resilient groundwater control system was required to ensure that the hydraulic groundwater head in underlying alluvium (clay, sand and gravel) and buried glacial channel (sand and gravel) was maintained below the excavation level in advance of and during the blockade works. Network Rail had the responsibility for undertaking the construction works. Its framework contractor J Murphy & Sons (Murphy) was appointed to build the culvert and its permanent designer Arcadis to design the culvert. The design included the construction of a 45m long precast concrete box culvert beneath the railway line. #technicalpaper #groundwater #construction #railway #culvert #groundengineering #CoolingPrize British Geotechnical Association
