KEEPING INDIA’S BOOMING IT INDUSTRY WATERPROOF - CASE STUDY I
1.Edelweiss/IBM
DESCRIPTION OF THE PROBLEM:
In 2008 Edelweiss, one of India’s leading financial service companies struck the highest deal in real estate by purchasing a 3 basement, G + 14 stored RCC building for approximately 250 crores with a built-up area of 2 lakh sq. ft. to house their corporate office. As part of their IT infrastructure, this building was also going to house Edelweiss’s main server room, battery room, electrical room, and UPS. The entire IT infrastructure for Edelweiss’s operation was designed, built, and maintained by IBM.
The structure consisted of RCC columns and PT slabs. In order to provide external glazing to the structure, extended cantilevers were cast along the entire periphery of the bldg. During June 2010 monsoon, rainwater seeped in through these extended cantilever portions which resulted in leakages in the server room and UPS area. It was also found that the existing PT slabs were porous resulting in the passage of water through the entire slab. This resulted in the shut down the mainframe thereby hampering entire trading activities of the company. Due to this major break down the clients demanded full proof waterproof system to ensure business continuity.
The clients approached Sunanda’s Concrete Materials Consultancy Division, based on our exemplary track record of delivering results. This site was especially complicated since the slab was post-tensioned and hence it was impossible to grout it. Consequently, the selection of a waterproofing system, design, implementation of a foolproof waterproofing specification, and on-job quality assurance assumes paramount importance.
Post a detailed inspection, identification of weak spots, the custom methodology was recommended, approved, and executed in a record time of 45 days.
MECHANISM OF WATERPROOFING
Mechanism of Waterproofing by Proper Cement Hydration
One of the products of hydration of cement is cementgel or Tobermorite, which is formed upto water cement ratio 0.65 to 0.7. At lower w/c ratio, it is formed more and more and vice versa. This hydration product has absolutely least co-efficient of permeability, i.e., 7x10-14 cm/sec and by itself blocks the pores and capillary in the concrete. This can result into good waterproof concrete of 10-10 to 10-12 cm/sec. However,...
Various permutations and combinations in specifications can avoid such problems, for example, the following alternatives can be considered:
1.Give a water impermeable coating on the finished surface of IPS – Though this method can prove effective on a short-term basis, may create problems subsequently. It is observed that the coatings based on pure solvent-based polymers, though effective do not function for a larger duration due to its requirement for a thoroughly clean and dry surface. From...
KEEPING INDIA'S BOOMING IT INDUSTRY WATERPROOF
The Information Technology industry in India has increased its contribution to India's GDP from 6.1% in 2009-10 to 6.4% in 2010-11. According to NASSCOM, the IT–BPO sector in India aggregated revenues of US$ 88.1 billion or Rs. 4.4 lakh crores in FY2011.
The combination of several factors makes India an attractive country for foreign investors and in particular for foreign investment for internet-based businesses. India is the 5th largest economy in the world ranking above France,...
