The Nuts And Bolts Of Successful Construction Projects: Fill & Download for Free

All over the world people are using Old Bridges made of Steel Collapsing . Materials used for the construction and Quality of Construction is the main reason .Old Godaveri Arch Bridge in River Godavari in the Raiway route from Vijayavada to Kolkata is 116 years Old now and All the Stone Masonry Pillar are still Standing Strong enough by defending the heavy water flow in this 4.5 km wide River . Maximum Speed of Wind in this area is 200km/hour. The location of Old & New bridges are only 60km away from the Bay of Bengal. Length of Every beam between two Pillars are 45 m and the Pillar are made with Stone Masonry .New Bridges Vs Old BridgesWhen comparing this Old Godaveri Arch Bridge with the Collapsed Flyover at Ganesh talkies in Kolkata, we can find that 116 year Old Stone masonry Pillar is Strong now also But the Pillar with Steel is Collapsed with Steel Beams above that in this generation . The British engineers constructed 4500m length bridge with in three years from 1897 to 1900 without any Hitech Machinery , But nowIVRCL company has done Suitcase Business with the Ruling Political Parties for the past Seven Years . The illegal tie up of Politicians and Contractors / Builders are the Reason behind the Tragedy of a Building Collapsed in Chennai in last year and now the the Collapsed Flyover in Kolkata . Engineers of the construction company and the Engineers in Government Department are equally responsible for this tragedy.Wrong Step of IVRCL company in Bridge Construction ManagementWhenever a company is starting a construction project in any states in our country , politicians of ruling party and the senior level engineers in Government Department will recommend the name of few engineers related to them . Contractor will be forced to deploy them As thy don't have any other choice . According to Construction management this is Old Story / Old Technic. Whenever a Politician / Officer in Government is recommending an engineer , we used to deploy him first in another project for Six months to One Year as a training policy of the company to understand about the engineer . In Engineers we can find Technically Handicapped Engineers, Officially Handicapped and Socially Handicapped Engineers . While deploying a New Engineer the Team Leader should identify in which category ( above mentioned three Category ) this engineer belongs to .So before giving permanent employment for an engineer came through Recommendation , we have to be very cautious /double cautious.Using Steel Made from Scrap by melting it in Re-Rolling MillAll the bridges mentioned below are more than Hundred years Old but still no damage for the main structure , Deck of these Bridges are also made of Steel . So why the Steel pillar and Beam of Flyover in Kolkata Collapsed . There is Only one Answer " Steel Of Old Age is made from The Iron Ore only " But 90% of the Steel available in Our Country is made out of Scrap . Steel Made from Scrap is Dominating the Market .Complete Scrap of World Trade Center is brought to the Tamil Nadu sea shore and through the RE-Rolling Steel Factory people of our country used it . Chennai , Bangalore, Gujarat, Kolkata and Chatisgarh are the Scrap Head offices .We are having only SAIL, Visakhapatanam Steel Plant and Tata Steel manufacturing Quality Steel from Iron Ore.List of Old Steel Bridges without any damage now(1) Old Howrah Bridge in Kolkata is opened for traffic in 1943 . This Bridge is having a length of 705 m is made of Steel Only.First Bridge in Kolkata " Pontoon Bridge " is Built by Sir Bradford Leslie in1874 and it was re-designed and Howrah Bridge was constructed in 1942**To bridge up the gap between Howrah and Kolkata .Previously, a Pontoon Bridge was built by Sir Bradford Leslie in 1874 .However, that bridge was Re-Designed and Howrah Bridge was constructed in 1942. It was opened for public use from February 1943. It took around 7 long years tocomplete the construction. In 1920, six engineers were recruited for apermanent bridge between Kolkata and Howrah. During the first term of the committee, Sir Rajendra Nath Mukherjee was the Chief Engineer for the project. Tata Steel supplied the steel.Howrah Bridge is counted among the busiest cantilever bridge across the globe. It is reckoned as an outstanding engineering work accomplished by the British. Amazingly, the entire structure of the bridge does not include any nuts or bolts. The bridge was made from 26500 tons of high tensile steel, supported by 2 piers. Each pier of the Bridge is around 90meters above the road . At the time of its construction, Howrah Bridge was acknowledged as the third longest cantilever bridge. Presently, it is the sixth longest bridge of its type in the World.Howrah Bridge features two sections that covered the whole bridge connecting both the sides. Howrah Bridge boasts a length of around 1528 feet and it has a width of about 62 feet.There were 7 feet wide pavements on either side of the bridge . The road of 48 feet with 8 lanes serves commuters and traffics all round the day. The Height of Howrah Bridge from the riverbed is 29 feet.Howrah Bridge bears a regular traffic load of roughly 90,000 vehicles and countless pedestrians. On June 14, 1965, the bridge was renamed after the Nobel laureate Rabindranath Tagore and famously called Rabindra Setu.(2) Old Godavari Arch Bridge across River Godavari in Andhrapradesh was oped for Rail Traffic in 1900, and having served its full utility period , was decommissioned in 1997.This bridge was 2nd longest bridge in Asia .Construction of the bridge commenced on November 11, 1897.This bridge was constructed with Stone Masonry and Steel Girder Beams above that . It has** 56span**s each of 45.7 m and is 3480m long. The rail bridge served its full life span of 100 years . The Bridge was named after Mr Arthur Elibank Havelock, Governer of Madras during British period . Chief engineer of this project was Mr Frederick Thomas Granville Walton and assistant engineerswere Mr R.A. Delanougerede, MrF.D.Couchman & Mr J.E.Eaglesome.(3) Golden Gate Bridge connecting San Francisco & California in US. Length of Bridge is 2737 m length opened for traffic in 1937. The Golden Gate Bridge is a suspension bridge spanning the Golden Gate strait between San Francisco Bay and the Pacific Ocean.(4) Old Tower Bridge in LondonLondon Bridge have spanned the River Thames between the City of London and Southwark , in central London. The current crossing, which opened to traffic in 1974, is a Steel Box girder bridge built from Concrete and Steel. This replaced a 19th Century Stone Arch Bridge, which in turn Superseded a 600 year old medieval structure . This was preceded by a succession of timber bridges, the first built by the Roman Founders of London.(5) Old London Bridge Built in 1209 was the first stone bridge in the world .This is the first Iron Bridge built in the world . This great bridge had 20 massive arches. It stood for over 600 years until it was demolished in 1831.The huge bridge actually had buildings, houses and shops in its entire length and was the only way to cross Thames river in in London . This bridge was constructed to shut down another Old Timber Bridges, built by the Roman founders of London.(6) Pamban Bridge of 2000m length ( Sea Bridge made of Steel with a length 2065m ) is opened for Train Traffic in 1914 . This was the first Sea Bridge in Asia and Longest Sea Bridge up to 2010 when we inaugurated Bandra Worli Sea Link Bridge. One Span in the Center of Pamban Bridge was having the Mechanism to fold up to give way for ships passing through the Sea.( 7) Old Steel Bridge in Kochi with a Mid Span having the Mechanism to fold up for the passage of Vessels passing through the Sea.This Old Mattancherry Bridge was built in 1940 by Mr Robert Charles Bristo. The bridge was built with wood and steel, and is a fine example of British Engineering. The bridge served its Designed Life Span till 1998 when the new bridge came close to it. Today the old Mattancherry Bridge is allowed only for two wheelers .(8) Steel Bridge 128 years Old in Feroke in Kozhikode .Now also all kind of vehicles are using this road as it is the only bridge connecting Feroke with Kozhikode. This is old road bridge. the bridge was completed in 1888. British Engineers has adopted a special method of filling its pillars with molten lead to add Strength and Flexibility .(7) Suspension Bridge / Hanging Bridge in PunalurThe first motorable bridge in India, constructed in 1877. It was built as a Suspension Bridge / Hanging bridge due to lack of Concrete Technology at that period and situated near the Kerala Tamil Nadu border . This bridge is known as the lap of Western Ghats and have a length of 400 foot. It was constructed in 1877 by Scottish Engineer Mr Albert Henry . This suspension bridge was built to prevent wild animals from crossing into the town from the forest area of " Old Kattu Pathanapuram ". As local residents were sceptical, the bridge engineer MrAlbert Henry demonstrated the Strength of Bridge by sitting in a Country Boat in the river under bridge with his family while Six Elephants crossed through the bridge .This may be the only bridge having the deck with Wood . Government has done the renovation of bridge and maintaining it as a Monument of Public Attraction.
