Thame Valley Viaduct
The Thame Valley Viaduct is a viaduct which will carry the High Speed 2 railway line in the United Kingdom. It traverses the River Thame near Aylesbury in Buckinghamshire. As early as February 2020, specific consultancies regarding the viaduct have been conducted. A competitive tender for its construction was undertaken during mid-2021. During April 2022, the final design for the viaduct was revealed. It is to be constructed by a joint venture of Eiffage, Kier, Ferrovial Construction and BAM Nuttall, collectively called ''EKFB''. The viaduct shall be largely pre-fabricated and assembled onsite; this approach is claimed to save time and money, while also aiming to reduce any impact upon the local community. Measures to minimise and mitigate the auditory and visual presence of the structure have been incorporated into the design. Once completed, the viaduct will have a length of 880 metres (2,890 feet) across its evenly-spaced 36 spans, while only having a height of . It is inten ...

High Speed 2
High Speed 2 (HS2) is a high-speed railway which has been under construction in England since 2019. The line's planned route is between Handsacre – in southern Staffordshire – and London, with a Spur line, branch to Birmingham. HS2 is to be Britain's second purpose-built High-speed rail in the United Kingdom, high-speed railway (after High Speed 1, the London to Channel Tunnel link). London and Birmingham are to be served directly by new high-speed track. Services to Glasgow, Liverpool, and Manchester are to use a mix of new high-speed track and the existing West Coast Main Line. The majority of the project is planned to be completed by 2033. The new track is being built between London Euston railway station, London Euston and Handsacre, near Lichfield in southern Staffordshire, where a junction connects HS2 to the north-south West Coast Main Line. New stations are planned for Old Oak Common railway station, Old Oak Common in northwest London, Birmingham Interchange railw ...

Steel
Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to steel's high Young's modulus, elastic modulus, Yield (engineering), yield strength, Fracture, fracture strength and low raw material cost, steel is one of the most commonly manufactured materials in the world. Steel is used in structures (as concrete Rebar, reinforcing rods), in Bridge, bridges, infrastructure, Tool, tools, Ship, ships, Train, trains, Car, cars, Bicycle, bicycles, Machine, machines, Home appliance, electrical appliances, furniture, and Weapon, weapons. Iron is always the main element in steel, but other elements are used to produce various grades of steel demonstrating altered material, mechanical, and microstructural properties. Stainless steels, for example, typically contain 18% chromium and exhibit improved corrosion and Redox, oxidation resistance versus its carbon steel counterpart. Under atmospheric pressures, steels generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concrete
Concrete is a composite material composed of aggregate bound together with a fluid cement that cures to a solid over time. It is the second-most-used substance (after water), the most–widely used building material, and the most-manufactured material in the world. When aggregate is mixed with dry Portland cement and water, the mixture forms a fluid slurry that can be poured and molded into shape. The cement reacts with the water through a process called hydration, which hardens it after several hours to form a solid matrix that binds the materials together into a durable stone-like material with various uses. This time allows concrete to not only be cast in forms, but also to have a variety of tooled processes performed. The hydration process is exothermic, which means that ambient temperature plays a significant role in how long it takes concrete to set. Often, additives (such as pozzolans or superplasticizers) are included in the mixture to improve the physical prop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carbon Neutrality
Global net-zero emissions is reached when greenhouse gas emissions and removals due to human activities are in balance. It is often called simply net zero. ''Emissions'' can refer to all greenhouse gases or only carbon dioxide (). Reaching net zero is necessary to stop further global warming. It requires deep cuts in emissions, for example by shifting from fossil fuels to sustainable energy, improving energy efficiency and halting deforestation. A small remaining fraction of emissions can then be offset using carbon dioxide removal. People often use the terms ''net-zero emissions'', ''carbon neutrality,'' and ''climate neutrality'' with the same meaning. However, in some cases, these terms have different meanings. For example, some standards for ''carbon neutral certification'' allow a lot of carbon offsetting. But ''net zero standards'' require reducing emissions to more than 90% and then only offsetting the remaining 10% or less to fall in line with 1.5 °C targets. Organ ...

Noise Barrier
A noise barrier (also called a soundwall, noise wall, sound berm, sound barrier, or acoustical barrier) is an exterior structure designed to protect inhabitants of sensitive land use areas from noise pollution. Noise barriers are the most effective method of mitigating roadway noise, roadway, railway, and industrial noise sources – other than cessation of the source activity or use of source controls. In the case of surface transportation noise, Noise mitigation#Roadways, other methods of reducing the source noise intensity include encouraging the use of Hybrid vehicles, hybrid and electric vehicles, improving Automotive aerodynamics, automobile aerodynamics and tire design, and choosing low-noise Pavement (material), paving material. Extensive use of noise barriers began in the United States after noise regulations were introduced in the early 1970s. History Noise barriers have been built in the United States since the mid-twentieth century, when vehicular traffic burgeoned. ...

Joint Venture
A joint venture (JV) is a business entity created by two or more parties, generally characterized by shared ownership, shared returns and risks, and shared governance. Companies typically pursue joint ventures for one of four reasons: to access a new market, particularly emerging market; to gain scale efficiencies by combining assets and operations; to share risk for major investments or projects; or to access skills and capabilities.' Most joint ventures are incorporated, although some, as in the oil and gas industry, are "unincorporated" joint ventures that mimic a corporate entity. With individuals, when two or more persons come together to form a temporary partnership for the purpose of carrying out a particular project, such partnership can also be called a joint venture where the parties are "''co-venturers''". A joint venture can take the form of a business. It can also take the form of a project or asset JV, created for the purpose of pursuing one specific project, ...

Invitation To Tender
An invitation to tender (ITT, also known as a call for bids or a request for tenders) is a formal, structured procedure for generating competing offers from different potential suppliers or contractors looking to obtain an award of business activity in works, supply, or service contracts, often from companies who have been previously assessed for suitability by means of a supplier questionnaire (SQ) or pre-qualification questionnaire (PQQ). Unlike a request for proposal (RFP), which is used when a company sources for business proposals, ITTs are used when a government or company does not require the submission of an original business proposal and is looking solely to award a contract based on the best tender submitted. As a result, whereas ITTs are often decided based on the best price offered, decisions on RFPs may also involve other considerations such as technology and innovation. Both are forms of reverse auction. At the same time, variants may be requested in an ITT, whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Right Of Way (public Throughway)
A right of way (also right-of-way) is a specific route that people, animals, vehicles, watercraft, or utility lines travel, or the legal status that gives them the right to do so. Rights-of-way in the physical sense include controlled-access highways, railroads, canals, hiking paths, bridle paths for horses, bicycle paths, the routes taken by high-voltage lines (also known as wayleave), utility tunnels, or simply the paved or unpaved local roads used by different types of traffic. The term ''highway'' is often used in legal contexts in the sense of "main way" to mean any public-use road or any public-use road or path. Some are restricted as to mode of use (for example, pedestrians only, pedestrians, horse and cycle riders, vehicles capable of a minimum speed). Rights-of-way in the legal sense (the right to pass through or to operate a transportation facility) can be created in a number of different ways. In some cases, a government, transportation company, or conservation no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
