great engineering feats.. succeses and failures

statesman

Mokshgundam visweswarayya was awarded SIR title by british rule for executing great engineering feat at vizag entrance channel for stopping sand and deepening the natural canal for movement of ships. he choose to sink two empty hulls of ships on specified location which has really stopped sand and made a usefull canal for ships to enter in to the port of vizag. todays countrys premierNo.1 port which is handling 55 million tonnes would not have been in existance without Sir.MV creative mind.

Memebers are requested to insert various engineering feats wether they are succesful or big failures in this tread.

Recent times big engineering failure

I was stunned to know GMR group which has executed national highway project between Tuni and Anakapalli section of NH5 on BOT basis and got 7 years lease rights to collect toll have done a big blunder in construction of high way by following PQC (Paved quality concrete) method by laying concrete road for speedy completion of project by engaging Madhukon constructions, a sub contractor who brought a paver from USA worth 8 crores, a very expensive machine for laying roads and completed the road in spite of knowing that this method is a failure in north indian highways. this PQC road has costed GMR 275 crores out of 575 crore total project cost and now the road has given away. GMR realised the same and started repairing the road by removing the total concrete in panels and recasting the road again. This failure is attributed to technology
and not only poor workman ship, what ever it is Rs. 275 crores money is criminal waste, besides expenditure for relaying, though government does not loose any thing, GMR has to foot the bill for recasting the road.

I don’t know whether this is classified as great engineering feat but when you go by train from Vizag to Araku, you wonder at the Herculean task that Indian Railways took to lay this hazardous track in the mountains and valleys of eastern ghats in a dense Dandakaranya forest. In fact the whole DBK ( Dandakaranya-Byladilla-Kirandol ) line, as it s popularly called, is an enginnering marvel of Indian Railways. The only other track that can challenge this is Konkan Railway in the Western ghats.

Vizag--kirandul railway line has been laid by a japanese company but not by indian railways off course for indian railways. This is a great engineering marvel with curved bridges that too simply supported shows the real excellence of civil engineering designed some 6 decades ago.
