Extremely exciting proposal by AW & CW. Seeing as the last public water supply reservoir (Carsington, Derbyshire) in the UK was built in 1991, I wonder what new methods, such as engineering, design & BNG, will be put to use. Worrying to read about the water shortfalls identified by Anglia and Cambridge, being 593Ml/day & 43.5Ml/d respectively. #watermanagement #dco #climatechange #reservoir #reservoirengineering

In the early 21st century, many oil and gas structures in the Gulf faced severe deterioration. These piled structures were built in the 70s and did not stand the test of time. The harsh weather conditions in the Gulf and Red Sea proved to be too much for the latest construction trends at the time. As an engineer, it is important to advise clients on what will last for the lifetime of the project. Comparing reinforced structures to plain concrete ones, it is clear that building with plain concrete is a wise choice for durability and maintenance. A special issue by CIRIA is even dedicated to concrete in the Gulf. Interestingly, coral reefs are a great example of marine structures that last for thousands of years, made of a material similar to concrete - calcium carbonate. Therefore, it is recommended to use calcium carbonate to build marine works that will stand the test of time. #port_engineering #coastalprotection #coastalengineering #marine_structures #marinas #waterfront #wateredge #engineering #extreme_events #environmentalimpact #the_gulf

🏔️ Slope Stability in Pipeline Construction: A Practical Calculation ⛰️ Slope stability analysis is crucial in ensuring the safety and success of pipeline construction projects, especially in dynamic environments like Trinidad and Tobago. Here’s a practical, simplified example of how to approach this: Scenario: A pipeline trench is planned on a slope: Slope height (H): 10 meters Slope angle (β): 30° Soil properties: Unit weight (γ): 18 kN/m³ Cohesion (c): 25 kPa Friction angle (φ): 30° Radius of circular failure surface: 12 meters Number of slices: 5 Goal: Calculate the Factor of Safety (FOS) to assess stability. Method: Using the Bishop’s Method of Slices for Limit Equilibrium Analysis, divide the slope into five sections and analyse the resisting and driving forces. Resisting force (R): c⋅ L+ (W ⋅cosα) ⋅ tanφ Driving force (D): W ⋅ sinα Here, W, the weight of each slice, is calculated as (γ⋅slice length.H)/number of slices. After completing the calculations: Resisting Force (R): Sum of cohesion and friction components. Driving Force (D): Total downslope weight component. Factor of Safety (FOS): R/D=2.39 Conclusion: The FOS of 2.39 indicates a stable slope (> 1.0) with a significant safety margin. This ensures the slope can handle planned excavation and construction activities without failure. Slope stability isn’t just about numbers—it’s about protecting people, projects, and the environment. A detailed analysis like this ensures safe and efficient operations in pipeline construction. How does your team address slope stability challenges?

Anchor tensioning can be a idle construction techniques to increase Gabion retaining wall stability. Something Papua New Guinea DoW should consider. It's expensive but serves long time service.

A geotechnical investigation is a series of tests and analyses conducted to understand the physical properties and behavior of soil, rock, and other earth materials at a specific site. The purpose of a geotechnical investigation is to provide critical information for the design and construction of infrastructure projects such as buildings, bridges, dams, and tunnels. The investigation typically includes site reconnaissance and geological mapping, borehole drilling and sampling, laboratory testing of soil and rock samples, In-situ testing (e.g., cone penetration tests, pressuremeter tests) This information is used to: - Determine suitable foundation designs - Optimize construction materials and methods - Assess potential risks and hazards (e.g., landslides, soil liquefaction) - Develop strategies for soil improvement and stabilization A thorough geotechnical investigation helps ensure the safety, efficiency, and cost-effectiveness of construction projects and longevity of a Superstructure.

Geotechnical reports are used to obtain information and data when proposing a plan for a new structure, or attempting to repair one that has fallen into disrepair due to subsurface conditions. Geotechnical reports coincide with site investigations and also delve into the construction capacity of soil or fill materials MKC INFRASTRUCTURE LIMITED #mkc #work #sitework

Muckshifters called up for £2.2bn Abingdon reservoir Thames Water is starting early supplier engagement with firms interested in delivering a 45 million cu m earthworks programme for its proposed new reservoir in Oxfordshire. Planned reservoir to south of Oxford, near Abingdon The Abingdon reservoir could cost up to £2.2bn to build and would supply water to 15m people across the South East. Consultants Arup and Binnies were appointed joint venture technical partners this summer with Costain securing a deal to start clay compaction trials to understand the ground conditions at the site. Costain Group PLC will deliver three test embankments, each around 50m long, 20m wide, and up to 3m high, using the same plant and methodology as the proposed reservoir embankments The fieldwork programme will help to inform an application for development consent in 2026. Indicative designs and an interim masterplan for the new reservoir, which has a capacity of up to 150m cu m and a surface area of 7km2, are now out to public consultation. If Development Consent is granted in 2028, construction is expected to start in 2029 for opening in 2040. The scale of opportunity for earthworks firms and heavy plant machinery is significant. An estimated t45million cu m of material will be excavated and moved to build the reservoir’s embankment structures, which rise to 15m and 25m The majority of the earthworks are expected to be carried out across six main summer working seasons (March to October). Mohit Farmah, head of procurement and supply chain at Thames Water, said: “Early engagement will ensure we have a pipeline of interested companies in place and ready to bid for contracts as soon as they are released.” As an initial step, companies with an interest in delivering the proposed earthworks programme are invited to complete a short market sounding questionnaire. Click for market briefing report, and the accompanying questionnaire can be found here. Thames Water is seeking responses by the 30 August.

Caisson sinking and underpinning shaft construction techniques are illustrated in this video briefly. These methods are generally used in soft ground condition. The caisson sinking can also be divided into dry and wet method. You can learn all these techniques in our Online Tunnel Engineering course in details. Our course also cover many other shaft and tunnelling construction methods.
