The recent completion of the Rockfall Mitigation Project along US 340 in West Virginia marks a significant milestone in enhancing safety and connectivity in the region. Led by Access Limited, a prominent rockfall mitigation firm, and Triton Construction Inc., the project was finished nearly two weeks ahead of schedule despite expanded scope requirements. Activities encompassed stabilizing the corridor through rock slope scaling, hazard removal, and rock bolting, along with repairing damaged pavement and guardrails. Additional measures like draped and pinned mesh, ground-level rockfall barriers, and on-slope attenuator systems were installed to minimize future rockfall risks. With the area's historical importance and high traffic volume, the project aimed to ensure safe passage for the estimated 24,500 daily vehicles, including commuters and tourists. Access Limited Construction, now a part of GeoStabilization International®, showcased its expertise and commitment to safety, completing the project efficiently while contributing to reduced carbon emissions from diverted traffic. #rockfallmitigation #geology #geotechnical #geotechnicalengineering

The stretch of coastline from Dawlish to Teignmouth in South Devon is a rare instance where two passions and interests meet - those being geotechnics and the railways. Since the inception of the South Devon Railway by Isambard Kingdom Brunel in 1844, this stretch of line has seen a fair share of trials of then unproven technology and methods; from the infamous Atmospheric Railway and the later experimental ballast epoxy trials to mitigate against washouts of the track bed, alongside the novel approaches taken to reinstate this artieral route from Exeter to Plymouth after Storm Desmond in 2014. Sometimes though, sticking to known principles does a world of wonders. Both rock meshes and rock bolts have been utilised on this stretch to help shore the stability of the area’s iconic red sandstones - a lithology known for high porosity and block failure with an increase in pore water pressure. These means of cliff stability management are seen to great effect behind the trialing powercar of one of Great Western’s Castle Class units, 43186 ‘Taunton Castle’ as it heads to Exeter St David’s. More recently, the completion of the rockfall shelter adjacent to the northern portal of Parson’s tunnel is a major undertaking by Network Rail to provide a final line of defence to aid in the upkeep of this scenic stretch of line. Although these type of structures have been in use for several decades in remote areas of Scotland, it’s hoped that this structure will provide further robustness to a line already threatened by more powerful storms. #devon #railway #geotechnical #engineering #cliff #networkrail #cliffstability #civilengineering

Ok so history was made last night in the Netherlands - late last night my Dutch friends and colleagues at Rijkswaterstaat were taking the brunt of #stormpia. Winds blowing across the north sea resulted in surges across their coastal defences with the Maeslantkering (Maeslant barrier) being closed in anger for the first time in its history to protect Rotterdam against a forecast storm surge of +3.17m NAP. Peter Vlam and his team were calm and professional in the first official deployment of the barrier monitoring the computer system known as 'BOS' and co-ordinating with the Port of Rotterdam ensuring the navigational traffic was stopped allowing the barrier to close. The barrier was closed at 20:10 with water levels rising to +3.34m NAP on the downward side of the barrier preventing a forecast level of +3.17m NAP of water in Rotterdam; some 170mm above the operational closure level of the barrier. The team successfully managed the closure through the night re-opening the barrier around 03:00 this morning and reinstating navigational traffic to the Port of Rotterdam. This barrier is the largest barrier with a ball-shaped joint hinge in the world, with the hinge diameter measuring 10 metres, and weighing 680 tonnes. The construction of the barrier cost 450 million euro and is the height of the Eiffel Tower - each side. More information can be found here on the structure - https://lnkd.in/enwncJMJ Well done to the team and everyone involved in ensuring we protect people and infrastructure. Often the unsung heroes working in the middle of the night when most are asleep not knowing how they are being protected. I wish you all a safe and well recovery from the event and a less 'excitable' Christmas and New Year.

One of the reasons I love working in Streaming analytics and IoT domain is the impact it has on real world critical scenarios. My first project in the IoT division at SAS was to integrate some of the calculations that Rijkswaterstaat (RWS) already had to calculate water surge, into SAS Event Stream Processing (ESP) to do real time calculations in buoys deployed out in the sea. Today morning when I was reading this post, the first thing that came to my mind was the possible impact those ESP servers running those calculations were having here. #iot #streamingdata #realtimeanalytics

Automatic closure of Maeslant barrier at designed 3 meter above NAP level (zero is about equal to average sea level in North Sea) !!!

As sea levels rise, we will see more such deployments. Governments at all levels must stop studying and start executing mitigation projects. Carbon taxes will not stop floods and storm surges. Infrastructure will. #civilengineering #Ports #climatemitigation #sealevelrise

At Cummins Cederberg - Coastal & Marine Engineering, we’re at the forefront of leveraging cutting-edge coastal engineering modeling to ensure the safety and efficiency of mooring operations for large cruise and oil vessels. 🚢 Our dedicated team is undertaking comprehensive dynamic mooring analyses, assessing the impact of various environmental factors such as wind, waves, and current on critical mooring components including bollards, fenders, and mooring lines. 🌊 Why is this analysis crucial, you may ask? Picture this: the loads exerted on mooring components could surpass their rated strength due to excessive motions. The repercussions could be dire, with mooring lines snapping under immense force, resulting in adverse impacts to infrastructure and overall safety at the mooring site. Our in-depth analyses establish safe vessel mooring conditions to help optimize arrangements and ultimately enhance port operations. By evaluating the vessel's response to environmental conditions we're able to provide site specific insights that drive informed decision-making. 📈✨ #CoastalEngineering #MooringAnalyses #MaritimeOperations #EngineeringExcellence
