Bent Flyvbjerg

Bent Flyvbjerg (born 1952) is a Danish economic geographer. He is Professor of Major Programme Management at Oxford University's Saïd Business School and the first Director of the University's BT Centre for Major Programme Management. He was previously Professor of Planning at Aalborg University, Denmark and Chair of Infrastructure Policy and Planning at Delft University of Technology, The Netherlands. He is a fellow of St Anne's College, Oxford.Flyvbjerg is the author or editor of 10 books and more than 200 papers in professional journals and edited volumes. His publications have been translated into 19 languages. His research has been covered by Science, The Economist, The New York Times, The Wall Street Journal, The Financial Times, The BBC, CNN, Charlie Rose, and many other media.Flyvbjerg received his Ph.D. in urban geography and planning from Aarhus University, Denmark. He has written extensively about megaprojects, decision making, city management, and philosophy of social science. He was a member of the Danish Infrastructure Commission and a director of the Danish Court Administration. He has twice held the Fulbright Scholarship. Bent Flyvbjerg was knighted in the Order of the Dannebrog in 2002.

His research has shown that competition between megaprojects and their sponsors creates political and organizational pressures that leads to the consistent overestimating of project benefits and the underestimating of project costs. The best megaprojects do not get implemented, but rather the ones that look best on paper. He argues that the ones that look best on paper are the ones for which costs and benefits have been misrepresented the most.

Customer Service System

The Customer Service System (CSS) of the BT Group (previously British Telecommunications) is the core operational support system for BT, bringing in 70% of income for the company (figures from 1997). BT rolled out CSS nationally in 1989 and provided an integrated system for telephony—order handling, repair handling and billing.BT Customer Service System (BT/CSS) was developed by Logica in 1984, costing £1bn to implement, representing the largest computer project undertaken in Europe and the largest integrated database in the world, at the time.In 2005, the CSS databases deployed by BT handled 23 million customers, with 13 terabytes of data spread out over 28 mainframe images. The databases supported 230 million transactions per day generated by over 40,000 users.CSS is still used by BT but it is now controlled by Openreach. BT retail migrated all accounts from CSS to a new billing system known as Geneva/Oneview/Avalon. This was to support the migration to WLR3.

Faraday Building

The Faraday Building was the GPO's first telephone exchange in London.

It started life as the Central telephone exchange at the Savings Bank building in Queen Victoria Street, opening for business on 1 March 1902 with just 200 subscribers. The Faraday Building is erected on the former site of Doctors' Commons, which had been the location of the Admiralty, Probate, and principal Ecclesiastical Court in England.

The Post Office’s first London telephone exchange served nearly two-and-a-half square miles of the capital – notable subscribers included the Treasury, the War Office and Fleet Street.

Take-up of the telephone by the public was very quick so that by 1905 the exchange capacity was extended to 10,000 subscribers, and full capacity was exhausted just three years later. To meet the growing demand from businesses in the City, a new common battery exchange was installed in 1906 with a capacity of 15,000 lines. This became 'City' exchange and officially opened in November 1907. In common with other exchanges in London, Central was able to connect subscribers to the Electrophone exchange at Gerard Street. Electrophone allowed people to listen to performances at certain London theatres and music halls while sitting at home.

In 1933, Faraday became the telephone centre of the world with the opening of the international telephone exchange. In 1935, an automatic exchange was opened with more than 6,000 working lines. The complex task of switching subscribers over to the new exchange involved 60 engineers and the opening was the culmination of more than 15 months’ hard work.

The construction of the Faraday Buildings obscured the riverside view of St Paul's Cathedral and directly led to the legislation protecting the views of St Paul's that has been used to thwart large buildings being erected around the various vantage points to see the cathedral. The City of London School and another telephone exchange, Baynard House, were built between the riverside and Faraday Building but are restricted in height to just three levels above ground.

During the Second World War, the Faraday Building was transformed into a redoubt where the Cabinet could retreat if the need arose and the Prime Minister could run the war in greater security than Downing Street could provide.

Guardian telephone exchange

Guardian Exchange was an underground telephone exchange built in Manchester in 1954. It was built together with the Anchor Exchange in Birmingham and the Kingsway exchange in London – all believed to provide hardened communications in the event of nuclear war. Today the underground site is used for telephone cabling. Constructed at a depth of 35 metres (115 ft), the tunnels are about 2 metres (80 in) in diameter. The exchange cost around £4 million (approximately £126 million in 2015 prices), part of which was funded by the United Kingdom's NATO partners.

International Network Services Inc.

International Network Services Inc. (INS) was a network architecture services provider based in Mountain View, California.

Following the collapse of the dot-com bubble, Lucent sold the unit back to employees and investors for an undisclosed sum. Then in 2007, INS was acquired by BT Group for £133 MM (now part of BT Advise Professional Services of BT (global services) based out of the USA.

Robin (answering machine)

The Robin is the sales name for the BT Answering Machine number 202A or 202B. It was released by British Telecommunications plc (now called BT Group) in 1985 and manufactured by Team Concepts International Ltd (Hong Kong).

The answering machine had a rather serious problem in that, if it was in "answer mode" and was inactivated (perhaps by a mains power failure), when the power was restored, it would not return to "answer mode" until the user manually restored it to such using a switch on the front of the machine. Despite this, it was a vast improvement on the BT Osprey answering machine.

St Nicholas Shambles

St Nicholas Shambles was a medieval church in the City of London, which stood on the corner of Butcher Hall Lane (now King Edward Street) and Newgate Street. It took its name from the Shambles, the butchers area in the west of Newgate Street. The church is first mentioned as St. Nicholas de Westrnacekaria. In 1253 Walter de Cantilupe, Bishop of Worcester granted indulgences to its parishioners.In 1546, Henry VIII gave the church, along with that of St Ewin (also known as St Audoen) and the dissolved Christ Church priory to the City corporation. A new parish was created for Christ Church, out of those of St Nicholas and St Ewin, and part of that of St Sepulchre. St Nicholas' was demolished in 1547.The site was extensively excavated in 1975–79 in preparation for construction of the GPO headquarters, (now the BT Centre). The excavations identified several phases of building. The original nave and chancel probably dated from the 11th century. They were extended in the late 12th century. Chapels were added to the east end in the 14th century, a north aisle was added to the nave in the first half of the 15th century, and, finally, the east end was rebuilt and a sacristy added on the north. The excavations included the grave yard. Among the finds was a woman who died in the later stages of childbirth.Surviving parish records, now held among the archives of St Bartholomew's Hospital, include an exceptionally detailed inventory of church books, plate, vestments and other possessions of 1457, and a series of churchwardens' accounts running from 1452 to 1526.

Tinshill BT Tower

The Tinshill BT Tower (also known locally as Cookridge Tower) is a 60.96 metres ( 200 ft) tall telecommunication tower located on the east side of Otley Old Road in the north of Leeds, West Yorkshire, England. It is in an elevated part of Leeds, with its base 192 metres above sea level. It is one of twelve BT towers built of reinforced concrete.

In 2002, prompted by a request from the local MP, Harold Best, it was the subject of a study by the Health Protection Agency, who concluded that the radio emissions from its various transmitters, were well below levels which might cause a risk to health for people nearby.

Tolsford Hill BT Tower

Tolsford Hill BT Tower is a telecommunication tower built of reinforced concrete at Tolsford Hill on the North Downs near Folkestone, Kent. Tolsford Hill BT Tower is one of the few British towers built of reinforced concrete and is 67.36 metres ( 221 ft) high.
