Foundation Failure of the St. Thomas Church, New Delhi

The St. Thomas Church was built in 1933 in New Delhi. By oversight it was founded on a graveyard having graves at two levels. The comparatively heavy rains of 1958 and 1964 showed wide spread damage by differential settlement and tilting of tower. During the investigations in 1959 by the Central Building Research Institute, Roorkee, the earlier history of the site and church was examined. It was found that excessive damage had occurred in 1943 also and underpinning of foundations and buttressing of walls was done to arrest it. Collapse of graves below the foundations was the reason for damage which reoccurred, mainly in the portions which were not underpinned or partially underpinned. Effectiveness and feasibility of remedial measures vis-a-vis the soil investigations are discussed

Foundation Strengthening and Protective Measures for Sri Sangameshwar Temple at Kudal Sangam, Karnataka

Sri Sangameshwara temple situated at the confluence of two rivers developed noticeable tilt. Also the temple site be inundated by the back waters of the dam during floods. An elaborate plan of dismantling the temple and reconstructing it by the same stone pieces and statuary could be carried through partially only and the sanctum santorum portion housing the ‘Lingam’ had to be retained. Now the entire temple is to be reconstructed as and where it was. The temple was founded on a boulder platform with hetrogeneous river deposits below it. Honouring the constraints of uninterrupted daily worship rituals in the temple and the underside of the pedestal supporting \u27Lingam’ not to be disturbed, strengthening by providing a double row of piles around the existing structure and a protective wall around the site were recommended. The choice and design aspects of these measures are discussed

SECURE AND RELIABLE POWER SUPPLY WITH CHALLENGES- SMART GRID

Smart Grid implementations will certainly increase the quantity, quality and use of information available from advanced sensing, computing and communications hardware as well as software. There is virtually universal agreement that it is necessary to upgrade the electric grid to increase overall system efficiency and reliability. Many technologies currently in use by the grid is outdated and in many cases unreliable. The reliance on old technology leads to inefficient systems, costing unnecessary money to the utilities, consumers and taxpayers. To upgrade the grid and to operate an improved grid will require significant dependence on distributed intelligence and broadband communication capabilities. The access and communications capabilities require the latest in security technology which are reliable for extremely large, wide-area communications networks. This paper discusses features, reasons of development, barriers and their solutions for a smart grid system
