Though work is expected to resume in about five weeks, the Dec. 24 collapse of a 50-meter-long portion of an unfinished, 1,100-m-long cable-stayed bridge, some 50 m above the river Chambal near Kota in Rajasthan, has left the National Highway Authority of India baffled. The accident killed more than 45 people. Many others still are missing. Crews are removing more than 8,000 tonnes of concrete that fell, killing more than 45 people. The $65-million project, 310 miles from New Delhi, consists of a 700-m-long cable-stayed structure with a 350-m main span and an access viaduct on either end. Hyundai Engineering
Environmentalists were disappointed by the two-week United Nations-sponsored Copenhagen climate- change summit, which failed to set binding emissions targets. But the Danish conference, attended by 119 government heads, has helped stimulate engineers to promote themselves as low-carbon champions. Indonesian floods are thought to be tied to climate change. Global summit in Copenhagen produced only an outline of how countries may address the issue, but engineering firms see clients who believe “decarbonizing” is going to happen.

The Delhi Metro Rail Corporation (DMRC) is close to completing tunneling for its second phase of construction, with less than 2 kilometers left out of 35 km, following the completion of India’s longest tunnel in an urban area built using the New Austrian Tunneling Method (NATM). The 2.85-km-long tunnel is part of the 22.7-km Airport Express Line, which will connect the Delhi city center to the international airport when completed in the summer of 2010.

Exasperated with neglect from the government of India’s eastern state of Bihar, two remote villages on top of a hill have built a 4-kilometer-long road using the most basic tools, including hammers, chisels and trowels. Barwan Kala and Barwan Khurd, located in the forested Kaimur Hills, have a combined population of 3,000. most of whom are farmers.

An investigation has been launched into why 1,000 sq m of roof was blown off Indira Gandhi International Airport’s six-month-old domestic terminal during a storm on Aug. 21 that had winds of over 90 kilometers per hour lasting 10 minutes. The section comprised about 5% of the 20,000 sq m high-tensile steel roof on the $100-million terminal. Photo: Manoj Kumar Investigators want to find out why new terminal roof section succumbed to wind. Delhi International Airport Ltd. (DIAL), the concessionaire that holds a contract to develop, manage and operate the airport, has formed a team to look into whether there
The global financial downturn has not passed over Macau, the world’s biggest gaming market. But work on four hotels of the 70% complete Las Vegas Sands development, stalled in November, is on course to begin again by the end of the year if the developer obtains financing to complete the $12-billion project, which includes an 1,800-room Sheraton and three casinos on reclaimed land known as the Cotai Strip. Rival Melco PBL Entertainment has raised $200 million in the U.S. to repay debts and accelerate repayments due on a $1.75-billion construction loan for the partially built $2.1-billion urban entertainment resort development,
A design flaw and inadequate concrete curing in a cantilevered segment of an elevated rail track being built in Delhi, India, caused the July 12 collapse that killed six people, according to a government report released on July 28. The rail agency Delhi Metro Rail Corp. (DMRC) may ban from further work the design-build contractor that holds several other contracts on the system. DMRC also is inspecting 87 piers previously constructed for the project. Photo: AP/Wideworld Report points to detailing flaws and concrete curing issues in girder collapse. A 4.2-meter-long cantilevered segment collapsed when crews with Gammon India, Mumbai, used
With an installed capacity of over 10,500 MW, India is currently the fifth-largest generator of wind power in the world. As it adds about 1,200 MW of wind capacity per year, the potential is far from depleted, but developers are faced with challenges in erecting the turbines in remote areas. Photo: Regen Wind Transporting large turbine blades to construction sites poses challenges. Unlike their Western counterparts, Indian developers often must find innovative means to transport large turbines through narrow, crowded roads to ill-equipped, hilly sites. “Non-availability of transport and cranes, lack of experienced manpower and infrastructure [lacking] such things as
A twofold collapse failure on a construction site for an extension of the Delhi Metro has officials investigating and rail opponents incensed. An elevated section of track came crashing down on July 12, killing six workers and injuring 20. One day later, three cranes trying to remove the launching girder had a “mechanical failure,” says Delhi Metro spokesman Anuj Dayal.
