Sea Link Protests

Posted by Kshitija Nadgouda on March 28, 2006

The Bandra-Worli sea link and the western freeway sea link project on the whole has come into the limelight again today, when the Indian Nightingale, Lata Mangeshkar announced that she would leave Mumbai if the flyover at Peddar Road was constructed.

It is sad to note that Lata Mangeshkar, a former Rajya Sabha member, is protesting this development only for personal issues -the proposed flyover alignment will obstruct the view from her first floor window.

The Peddar Road Residents Association (PRRA) is planning to take legal action against the PWD (Public Works Department) for witholding traffic survey data for the same flyover. The PRRA are of the opinion that the sea link project will ease traffic and congestion issues even without the Peddar Road flyover which was evident from traffic suvey that was withheld from them. They plan to meet Member of Parliament Milind Deora and also take a delegation to the central environmental ministry.

These two forms of protest caught my eye – both protesting the same issue, but in very different ways and for different reasons! Development versus Environment has always been a big issue worldwide. While everyone agrees that development is essential for the development of human race, nature and environment should not be sacrificed as a result.

India needs to have stricter Environmental laws and more stringent implementation of these laws. The Ministry of Environment and Forestry (MoEF) issued an environmental clearance for the project in February 2003. Several issues of concern pointed out by the Indian People’s Tribunal of Environment and Human Rights that I talked about on Friday, have been addressed.

The current quality of air, water and sound pollution have been studied and the impact on them during and after construction have been predicted. It will now be necessary to monitor these during and after construction and if they are exceeding the permissible limits, corrective action needs to be taken dynamically.

The question that arises is: Are the concerned Indian Government agencies and Departments pro-active and dynamic enough to handle this? It will remain to be seen…

Bandra Worli Sea Link in Mumbai, India

Posted by Kshitija Nadgouda on March 23, 2006

BWSL Visions
(Courtsey Dar Consultants)

The Bandra-Worli Sea link (BWSL) is an on-going project connecting the western suburbs of Mumbai to downtown proposed to be completed in 2007. The BWSL is a part of the Western Freeway Sea Link (WFSL) project undertaken by the Maharashtra State Road Development Corporation (MSRDC). It will be an alternate route for office-goers working in downtown, by-passing the Mahim Causeway.

(Courtsey MSRDC)

The BWSL with a total length of 5.6km, will have 8 lanes, expanding to 16 lanes at the automated toll plaza in Bandra. Two cable stayed bridges with a minimum clearance of 20m (for marine traffic) are proposed. The flyovers will rest on open foundations, and the bridges will rest on pile (drilled shaft) foundations. Lachel Felice and Associates, Inc. have been awarded the geotechnical design and supervision for the project.

In 2001, the Indian People’s Tribunal on Environment and Human Rights conducted a detailed inquiry on the necessity and feasibility of the BWSL. Several environmental issues were raised in the report they presented. Some of those are listed below:

  • Encroachment within the Coastal Regulation Zone (CRZ).
  • Negative impact on environment such as degradation of downstream water quality.
  • Negative impact on livelihood of fishermen due to reclamation of fishing areas.
  • Negative impact on marine ecology
  • Possible coastal erosion or silting of downstream water bodies
  • Increased traffic to increase severity of air pollution

Today’s post is dedicated to a few of the zillions of geotechnical resources available on the internet for Geotechnical Engineers.

Thats all I have time for today!

I was introduced to blogging by my husband – who not just encouraged me to start blogging, but almost nagged me into doing it. So here I am, trying my hand at it. From what he tells me, it seems addictive – lets see if I get hooked on to it! Check out his blog at Abhijit Nadgouda @ iface.

My interest in Geotechnical Engineering was kindled by our professor in Engineering College (Sardar Patel College of Engineering), Dr. S. Y. Mhaiskar. From Soil Mechanics to Machine Foundations, he made everything easy to understand but challenging at the same time.

So what in the world is Geotechnical Engineering you ask? Geotechnical Engineering is the study of soil in relation to the structures built on it. The structure could be as small as a pedestal or as large as a high rise. The behaviour of the soil resting under any structure will vary based on several factors such as type of soil, presence of ground water, type and size of the proposed structure, etc. The prediction of this sub-surface behaviour, the actions and remedial measures designed to mould it as per our requirements, constitutes a part of Geotechnical Engineering.
