Sheppey Crossing
The Sheppey Crossing is a bridge which carries the A249 road across The Swale (a tidal strait of the Thames Estuary), linking the Isle of Sheppey with the mainland of Kent. The four-lane crossing measures 21.5 m (71 feet) in width, at a height of 35 m (115 feet) over the water. The A249 links the M20 and M2 motorways to Sheppey. The bridge opened in 2006, and it provides an alternative highway to the neighbouring Kingsferry Bridge that was completed in 1959. The Sheppey Crossing is not open to pedestrians, bicycles, or horses, and these continue to use the older bridge, as does the railway line to Sheerness. Both bridges are monitored by an automatic number plate recognition (ANPR) system to detect lawbreaking vehicles. Construction The bridge was constructed as part of a £100 million plan to improve the A249 between the M2 and the port of Sheerness. The Kingsferry Bridge, which previously carried the A249, suffers from two major drawbacks: It has only one lane in each dire ...

Dual Carriageway
A dual carriageway ( BE) or divided highway ( AE) is a class of highway with carriageways for traffic travelling in opposite directions separated by a central reservation (BrE) or median (AmE). Roads with two or more carriageways which are designed to higher standards with controlled access are generally classed as motorways, freeways, etc., rather than dual carriageways. A road without a central reservation is a single carriageway regardless of the number of lanes. Dual carriageways have improved road traffic safety over single carriageways and typically have higher speed limits as a result. In some places, express lanes and local/collector lanes are used within a local-express-lane system to provide more capacity and to smooth traffic flows for longer-distance travel. History A very early (perhaps the first) example of a dual carriageway was the ''Via Portuensis'', built in the first century by the Roman emperor Claudius between Rome and its port Ostia at the mouth of t ...

Automatic Number Plate Recognition
Automatic number-plate recognition (ANPR; see also #Other names, other names below) is a technology that uses optical character recognition on images to read vehicle registration plates to create vehicle location data. It can use existing closed-circuit television, road-rule enforcement cameras, or cameras specifically designed for the task. ANPR is used by police forces around the world for law enforcement purposes, including to check if a vehicle registration, vehicle is registered or Vehicle licence, licensed. It is also used for electronic toll collection on road pricing, pay-per-use roads and as a method of cataloguing the movements of traffic, for example by highways agencies. Automatic number-plate recognition can be used to store the images captured by the cameras as well as the text from the license plate, with some configurable to store a photograph of the driver. Systems commonly use infrared lighting to allow the camera to take the picture at any time of day or night ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jack (mechanical)
A jack is a mechanical lifting device used to apply great forces or lift heavy loads. A mechanical jack employs a screw thread for lifting heavy equipment. A hydraulic jack uses hydraulic power. The most common form is a car jack, floor jack or garage jack, which lifts vehicles so that maintenance can be performed. Jacks are usually rated for a maximum lifting capacity (for example, 1.5 tons or 3 tons). Industrial jacks can be rated for many tons of load. Etymology The personal name ''Jack'', which came into English usage around the thirteenth century as a nickname form of ''John'', came in the sixteenth century to be used as a colloquial word for 'a man (of low status)' (much as in the modern usage 'jack of all trades, master of none'). From here, the word was 'applied to things which in some way take the place of a lad or man, or save human labour'. The first attestation in the ''Oxford English Dictionary'' of ''jack'' in the sense 'a machine, usually portable, for lifting ...

Marsh
A marsh is a wetland that is dominated by herbaceous rather than woody plant species.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p Marshes can often be found at the edges of lakes and streams, where they form a transition between the aquatic and terrestrial ecosystems. They are often dominated by grasses, rushes or reeds. If woody plants are present they tend to be low-growing shrubs, and the marsh is sometimes called a carr. This form of vegetation is what differentiates marshes from other types of wetland such as swamps, which are dominated by trees, and mires, which are wetlands that have accumulated deposits of acidic peat. Marshes provide habitats for many kinds of invertebrates, fish, amphibians, waterfowl and aquatic mammals. This biological productivity means that marshes contain 0.1% of global sequestered terrestrial carbon. Moreover, they have an outsized influence on climate resi ...

Private Finance Initiative
The private finance initiative (PFI) was a United Kingdom government procurement policy aimed at creating "public–private partnerships" (PPPs) where private firms are contracted to complete and manage public projects. Initially launched in 1992 by Prime Minister John Major, and expanded considerably by the Blair government, PFI is part of the wider programme of privatisation and financialisation, and presented as a means for increasing accountability and efficiency for public spending. PFI was controversial in the UK. In 2003, the National Audit Office felt that it provided good value for money overall; according to critics, PFI has been used simply to place a great amount of debt "off-balance-sheet". In 2011, the parliamentary Treasury Select Committee recommended: In October 2018, the then-chancellor Philip Hammond announced that the UK government would no longer use PFI; however, PFI projects will continue to operate for some time to come. In 2021, Robert Naylor warned ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carillion
Carillion plc was a British multinational construction and facilities management services company headquartered in Wolverhampton in the United Kingdom, prior to its liquidation in January 2018. Carillion was created in July 1999, following a demerger from Tarmac. It grew through a series of acquisitions to become the second largest construction company in the United Kingdom, was listed on the London Stock Exchange, and in 2016 had some 43,000 employees (18,257 of them in the United Kingdom). Concerns about Carillion's debt situation were raised in 2015, and after the company experienced financial difficulties in 2017, it went into compulsory liquidation on 15 January 2018, the most drastic procedure in UK insolvency law, with liabilities of almost £7 billion. In the United Kingdom, the insolvency caused project shutdowns and delays in the UK and overseas (PFI projects in Ireland were suspended, while four of Carillion's Canadian businesses sought legal bankruptcy protection) ...

Tonne
The tonne ( or ; symbol: t) is a unit of mass equal to 1000 kilograms. It is a non-SI unit accepted for use with SI. It is also referred to as a metric ton to distinguish it from the non-metric units of the short ton ( United States customary units), and the long ton ( British imperial units). It is equivalent to approximately 2204.6 pounds, 1.102 short tons, and 0.984 long tons. The official SI unit is the megagram (symbol: Mg), a less common way to express the same mass. Symbol and abbreviations The BIPM symbol for the tonne is t, adopted at the same time as the unit in 1879.Table 6 . BIPM. Retrieved on 2011-07-10. Its use is also official for the metric ton in the United States, having been adopted by the United States |
Structural Awards
The Institution of Structural Engineers' Structural Awards have been awarded for the structural design of buildings and infrastructure since 1968. The awards were re-organised in 2006 to include ten categories and the Supreme Award for structural engineering excellence, the highest award a structural project can win.

Special Protection Area
A Special Protection Area (SPA) is a designation under the European Union Directive on the Conservation of Wild Birds. Under the Directive, Member States of the European Union (EU) have a duty to safeguard the habitats of migratory birds and certain particularly threatened birds. Together with Special Areas of Conservation (SACs), the SPAs form a network of protected sites across the EU, called Natura 2000. Each SPA has an EU code – for example the North Norfolk Coast SPA has the code ''UK9009031''. In the United Kingdom As at 21 September 2006, there were 252 classified SPAs and 12 proposed SPAs in England, Scotland, Wales and Northern Ireland. The Conservation (Natural Habitats etc.) Regulations 1994 implement the terms of the Directive in Scotland, England and Wales. In Great Britain, SPAs (and SACs) designated on land or in the intertidal area are normally also notified as Sites of Special Scientific Interest (SSSIs), and in Northern Ireland as Areas of Special Scientific ...

Vertical-lift Bridge
A vertical-lift bridge or just lift bridge is a type of movable bridge in which a span rises vertically while remaining parallel with the deck. The vertical lift offers several benefits over other movable bridges such as the bascule and swing-span bridges. Generally speaking, they cost less to build for longer moveable spans. The counterweights in a vertical lift are only required to be equal to the weight of the deck, whereas bascule bridge counterweights must weigh several times as much as the span being lifted. As a result, heavier materials can be used in the deck, and so this type of bridge is especially suited for heavy railroad use. The biggest disadvantage to the vertical-lift bridge (in comparison with many other designs) is the height restriction for vessels passing under it, due to the deck remaining suspended above the passageway. Although most vertical-lift bridges use towers, each equipped with counterweights, some use hydraulic jacks located below the deck. ...
